91 TASCAM 788 Digital PortaStudio 10 – Routing and scene libraries The 788 allows you to store and recall commonly- used assignment (routing) patterns as well as scenes which contain the settings for the mixer. Up to 10 scene settings may be stored in a library area for each song, which is automatically stored when the song is saved.Routing patterns are stored in a common library area, available to all songs, and are automatically saved when the 788 is powered down. There is no need to perform a special operation to save either type of library data. Routing libraries In the routing library, you store up to 128 patterns of input assignments to library entries. The assignments stored in the routing patterns include: the assignments of the inputs to the mixer channels (see “Assigning sources to mixer channels.” on page 36)the inputs to the sub-mixer (see “Assigning inputs to the sub-mixer” on page 37) the effect assignments (see “Setting up EFFECT 1” on page 81 and “Setting up EFFECT 2” on page 82). NOTE The assignments of virtual tracks to tracks are not stored as part of a routing patterns. These assignments are stored as part of a song. Saving the current routing settings to the library You can save to the routing library while playback is stopped, or while playing back or recording. To store the current routing settings to a library entry: 1Press the QUICK SETUP key. 2Use the dial to scroll down to the ROUTING LIB. entry in the list, and press ENTER: 3There are two tabs on the top of this display: the READ tab allows you to read settings from the library, and the SAVE tab allows you to store the current settings to the library.If the SAVE tab is not highlighted, press the Á key to highlight it. 4Use the dial to scroll to the entry where you want to store the current settings. TIP You can give a title to the highlighted entry at this point, fol- lowing the instructions in “Entering and editing titles” on page 26. 5Press ENTER. The settings are saved and the display returns to the home screen.
10 – Routing and scene libraries–Scene libraries 92 TASCAM 788 Digital PortaStudio Loading routing settings from the library You can load previously stored routing settings from the library while playback is stopped, or while play- ing back or recording. NOTE Take care when changing routing settings via MIDI control while playing back or recording, as major changes to the routing settings may “open up” some channels and close others, giving unexpected results, which could result in a spoiled recording or even damage to monitoring equipment and your ears. To load routing settings from a stored library entry: 1Press the QUICK SETUP key.2Use the dial to scroll down to the ROUTING LIB. entry in the list, and press ENTER: 3Use the dial to scroll to the entry from where you want to load the new routing settings. 4Press ENTER. The settings are loaded and the display returns to the assign map screen (see “Viewing assignments” on page 37), where you can view the effects of the load. Scene libraries The 788 also allows you to load and store up to ten mixer scenes in a library for each song. These scenes are stored automatically when the song is saved. The 788 stores the following mixer settings as part of a scene: Input assignment (including virtual track assignment) EQ settings Effector settings and assignment Effect and aux send levels PanDigital pad/gain Track cue mixer settings (level and pan) Fader settings (including the STEREO fader) Sub-mixer settings Since routing is included as part of a mixer scene, you do not need to store routing assignments sepa- rately from scenes unless you need to use the routing assignments in other songs. NOTE Monitor settings (selection and level), and TRIM control settings, are not stored as part of a scene. Saving a scene to the library You can save to the scene library while playback is stopped, or while playing back or recording. To store the current scene settings to a library entry: 1Press the QUICK SETUP key. 2Use the dial to scroll down to the SCENE LIB. entry in the list, and press ENTER:3There are two tabs on the top of this display: the READ tab allows you to read scenes from the library, and the SAVE tab allows you to store the current scene to the library. If the SAVE tab is not highlighted, press the Á key to highlight it. 4Use the dial to scroll to the entry where you want to store the current settings. TIP You can give a title to the highlighted entry at this point, fol- lowing the instructions in “Entering and editing titles” on page 26. 5Press ENTER. The scene is saved and the dis- play returns to the home screen.
10 – Routing and scene libraries–Scene libraries TASCAM 788 Digital PortaStudio 93 Loading scenes from the library You can load previously stored scenes from the library while playback is stopped. You cannot load scenes (or change scenes using MIDI Program Change commands) while playing back or recording. If you attempt this, a message appears: TRANSPORT MOVING. To load scenes from a stored library entry: 1Press the QUICK SETUP key. 2Use the dial to scroll down to the SCENE LIB. entry in the list, and press ENTER:3Use the dial to scroll to the entry from where you want to load the scene. 4Press ENTER. The scene is loaded and the dis- play returns to the assign map screen (see “Viewing assignments” on page 37), where you can view the effects of the load. Other matters concerning scenes Because the physical position of the faders on the 788 may not always match the position of the faders as recalled by the scene, this may cause unexpected results if you do not consider in advance what is hap- pening when a scene is loaded. This section explains some of the issues involved. In this example, a channel’s physical fader is set at a high level, and a scene is loaded from the library, where the internal fader setting is at a lower level. NOTE This also applies to the STEREO fader, as well as the individual channel faders. As explained in “Internal and physical faders” on page 45, this means that when the FADER/PAN screen for the channel is shown, the values of both the internal fader and physical fader are shown: The menu option described earlier in “Internal and physical faders” on page 45 allows you to specify what will be done when an internal fader value is loaded which is different from the physical fader value. The CATCH option is probably the best option to choose in many cases, allowing you to leave the channel level unchanged until the physical fader catches the internal fader (that is, it matches the level of the internal fader). The REAL option ignores the internal fader level which has been loaded—the physical fader is the only method of setting the level. The JUMP option means that if the physical fader is moved, though, the level will instantly jump (up or down) to the physical fader position. This can cause unexpected results, and should be used with caution. Physical fader Internal fader Internal value and marker Physical fader value and marker
94 TASCAM 788 Digital PortaStudio 11 – Synchronization You can expand the options available to you when using the 788 by connecting it and synchronizing it to other musical equipment. Typically, this extra equipment will be MIDI-based (sequencers, drum machines, synthesizers, etc.). Of course, although it is possible to record MIDI instruments on the 788 tracks during the initial stages of the recording project, it may make more sense to use the eight audio tracks of the 788 for material that cannot be automated via MIDI (guitars and other acoustic instruments and of course vocals). When it comes to mixdown time, the 788 allows you to extend the eight available audio tracks by playing additional sources through the sub-mixer and adding them to the mix (see “Sub-mixer” on page 48). To make this work, though, the MIDI instruments and the 788 must be synchronized to each other, so that playback on one set of sound sources (the recorded audio tracks) keeps time with the sequenced MIDI tracks. The 788 can synchronize with MIDI equipment in a number of different ways, as explained in this sec- tion, allowing a high degree of flexibility in the setup. As well as synchronizing to other devices, it is also possible for the 788 to control other devices or to be controlled by them (see “MMC and MIDI functions” on page 101). NOTE All synchronization is carried out through the two MIDI ports on the rear panel of the 788, no matter what kind of synchronization is used, or the role of the 788 in the syn- chronization chain. The 788 cannot use audible SMPTE/EBU timecode from the timestripe track of a tape. If the source to be synchro- nized with the 788 only has audible timecode available, it must be converted to and from MIDI timecode (MTC) as appropriate. Master or slave? The terms master and slave are used to name the con- troller and the controlled units in a chain of devices such as the 788 and other audio devices. However, it is possible for a unit to be a master unit in one configuration at the same time as being a slave in another.For example, the 788 may be set up to be a timecode master (other units receive their timecode from the 788 and act accordingly), and a control slave (it receives stop/start commands, etc.) from other units. A 788 can also be a timecode (MTC) slave, and in this way, two 788s can be synchronized. How to measure time? There are two ways of counting time in music: one is the number of minutes and seconds since the begin- ning of the piece. This is the way in which tape recorders, etc. count time. The other method of counting time is the number of bars (measures) since the beginning of the piece. This is the way in which MIDI sequencers typically count time.There is no direct relationship between these two ways of counting, as the relationship depends on the tempo of the piece. When synchronizing, therefore, one unit in the chain must be capable of making a map which relates the minutes and seconds of one system to the bars and beats of the other. If the tempo stays fairly constant throughout a piece, this is a matter of fairly simple arithmetic, but if the tempo changes through a piece, this is not so easy to do.
11 – Synchronization–Synchronization methods TASCAM 788 Digital PortaStudio 95 Synchronization methods The 788 can use the following output synchroniza- tion methods for synchronization with other units: MIDI Time Code (MTC) This is an absolute time position, which allows times to be defined to frame accuracy or better (the number of frames in a second depends on the frame rate, as explained later in this section). MTC has no direct relation to bars and beats in a song. MIDI clock A MIDI clock defining the tempo at which a MIDI song is played back can be recorded. MIDI Song Position Pointer (SPP): MIDI Song Position information data is used to position the slave device at the correct position in a song, expressed in bars and beats. Song Position Pointer information alone has no relationship to absolute time (minutes and seconds). Synchronization settings on the 788 These synchronization methods listed above are used in the following way by the 788 when it is acting as a synchronization master for other units: MTC The 788 outputs MIDI Timecode to the slave unit. It is the responsibility of the slave unit (sequencer, etc.) to turn this timecode into musically meaningful, i.e. bars and beats, information. This can also be used to synchronize another recording device which is not MIDI-based, but which can accept MTC, for example, another 788. syncTrk (sync track) In this way of working, the 788 is synchronized to a slave MIDI device (sequencer, etc.) which is capable of recognizing and acting on MIDI clock and SPP information. The tem- pos to be used throughout the piece are first worked out on the slave device, and they have been finalized, the sequencer plays MIDI into the 788, which records the clock. The 788 can then play back these tempos, along with SPP information, and thereby act as a MIDI clock master for the system. Tempo Map In this way of working, the tempos and time signatures throughout the song are entered on the 788, which then acts as the master unit, calcu-lating the clock timings and transmitting them, together with Song Position Pointer information, to the slave devices. In addition, the 788 can synchronize as a slave to incoming timecode (MTC), generated by a MIDI sequencer, etc. Note, however, that the MTC output by some computer systems may be a little erratic and unstable, and it is recommended that you do not use this method of synchronization with sequencers, but rather with other recording devices which can output stable MTC (such as other 788s). Each of these different synchronization methods has its advantages and disadvantages. The most impor- tant thing to remember is that once something is recorded on the 788, it is impossible to change its tempo. By contrast, if something is recorded on a MIDI sequencer, it is easy to change its tempo. For these reasons, you may find it easiest to deter- mine the tempo on the sequencer, and record the MIDI sync track (click track) first. After you are completely happy with the tempo of this track, you can start to add the acoustic instruments, and lock the timing of the recorded sounds to that of the MIDI data.
11 – Synchronization–Making synchronization settings 96 TASCAM 788 Digital PortaStudio Making synchronization settings The 788 synchronization settings are all carried out using the SYNC/MIDI menu. All synchronization information is carried through MIDI, so typically the MIDI OUT of the 788 must be connected to the MIDI IN of the MIDI device to which it is being synchronized, and the MIDI IN of the 788 should be connected to the MIDI OUT of the other unit. Synchronization master/slave setting on the 788 To determine whether the 788 will act as the master or the slave with regard to synchronization: 1Make sure playback and recording are stopped, and press the MENU key. 2Use the dial to scroll down to SYNC/ MIDI , and press ENTER. 3Use the dial to highlight SYNC, and press ENTER. 4Use the § and ¶ keys to move the cursor to SYNC SRC. 5For internal synchronization (that is, the 788 becomes a synchronization master), use the dial to select INT. For external synchroniza- tion (synchronization slave), use the dial to select EXT. NOTE If external synchronization is selected, the 788’s transport keys (including jog and repeat) will not work until the syn- chronization is received at the MIDI IN port. This is shown when you try to play or record, for example, by the appro- priate key indicators flashing until the MTC is received. The 788 display also shows EXT SYNC when external synchronization is selected as explained here. 6Press ENTER to return to the home screen, or use the § and ¶ keys to select another option. Selecting the master synchronization type If the 788 is set to be the synchronization master, you must then set the type of synchronization signal out- put to the slave units: 1Make sure playback and recording are stopped, and press the MENU key. 2Use the dial to scroll down to SYNC/ MIDI , and press ENTER. 3Use the dial to highlight SYNC, and press ENTER. 4Use the § and ¶ keys to move the cursor to SYNC GEN. 5There are four options available here (explained in more detail in “Synchronization methods” on page 95): OFF The 788 does not output any timing or sync information from the MIDI OUT when playing back or recording. MTC MIDI Time Code—the 788 outputs MIDI timecode when playing back or recording. CLOCK The 788 outputs a MIDI clock together with the Song Position Pointer information from the edited Tempo Map (see “Tempo map” on page 98) to synchronize an external sequencer. SycTRK The 788 plays back a previously-recorded sync track (see “Sync track” on page 97) with SPP information, to synchronize an external sequencer. NOTE When the 788 is acting as a synchronization slave, the only synchronization source which is valid is MIDI Timecode. MIDI Timecode frame rate MIDI Timecode allows the use of different frame rates, which allow synchronization with all types of timecode available from other devices. 1Make sure playback and recording are stopped, and press the MENU key.2Use the dial to scroll down to SYNC/ MIDI , and press ENTER. 3Use the dial to highlight SYNC, and press ENTER.
11 – Synchronization–Sync track TASCAM 788 Digital PortaStudio 97 4Use the § and ¶ keys to move the cursor to FRAME RATE. 5Use the dial to select the frame rate for the out- going timecode (or timecode to be received as a slave).6Press ENTER to return to the home screen, or use the § and ¶ keys to select another option. When you have made the selection on the 788, the other device (sequencer) must also be set to the same frame rate as that set on the 788. If they are different, you will not be able to synchronize the system prop- erly. This applies whether the 788 is acting as a time- code slave or a timecode master in the system. TIP We suggest that unless you are working with video or mov- ies, you use the 30ND setting, as this provides more frames per second, and hence greater precision. MIDI Timecode offset (788 as slave only) When the 788 is slaved to incoming MIDI timecode, you may need to adjust the time difference, so that the time used on the 788 closely corresponds to the “real” time. For example, if the MIDI timecode master starts the timecode playback at 00:57:00:00, and the actual piece starts at 01:00:00:00, you might want to enter an offset of 3 minutes, so that when the piece starts, the ABS time on the 788 display shows 01:00:00:00 (see “The time display” on page 26). The MTC setting on the screen display will always show the incoming timecode values. 1Make sure playback and recording are stopped, and press the MENU key.2Use the dial to scroll down to SYNC/ MIDI , and press ENTER. 3Use the dial to highlight SYNC, and press ENTER. 4Use the § and ¶ keys to move the cursor to MTC OFFSET. 5Use the Ó and Á keys to move the cursor to the hours, minutes, seconds and frames field, and use the dial to adjust these values. NOTE The maximum value you can set here is 23:59:59:xx (where xx is one less than the number of frames in a sec- ond—see “MIDI Timecode frame rate” on page 96). Sync track You can record a sync track from the source MIDI device, which allows the 788 to act as the synchroni- zation master later on.The sync track is not an audio track, but is a record of the MIDI clock. When replayed, SPP information is included. It allows subtleties in tempo which are not possible with the tempo map method of working Recording the sync track Before starting to record the sync track, make sure that: the tempo changes of the sequence are fixed and will not be changed in the future the MIDI OUT of the sequencer is connected to the MIDI IN of the 788 the sequencer is set to transmit MIDI Clock and information when replaying 1Make sure playback and recording are stopped, and press the MENU key.2Use the dial to scroll down to SYNC/ MIDI , and press ENTER. 3Use the dial to highlight SYNC TRACK, and press ENTER. 2424 frames/second.

11 – Synchronization–Tempo map 98 TASCAM 788 Digital PortaStudio 4Cue the sequencer to the start of the song (it is not possible to record from part of the way through). 5Press ENTER/YES on the 788. The sync track is now “armed” and the display shows Wait for Start . 6Start playing back the sequence. If the connec- tions have been made properly, the 788 display shows Recording... To interrupt the recording of the sync track before the end, press NO.7At the end of the sequence, or if the sequence is stopped, the 788 display shows Complete. Press EXIT/NO to save the sync track. If you press ENTER/YES at this point, you will re-arm the sync track and you will have to record it again. NOTE The 788 and the sequencer should be independently con- trolled here (that is, neither should be a control slave of the other). See “MMC and MIDI functions” on page 101. The start of the sync track is always the ABS 00:00:00:00 point, that is, the first beat of the first bar falls at the zero point. It is not possible to offset the sync track. Using the sync track To use the recorded sync track to control the external sequencer from the 788: 1Make sure that the synchronization source for the 788 is set to INT (internal)—see “Syn- chronization master/slave setting on the 788” on page 96. The MIDI OUT of the 788 should be connected to the MIDI IN of the sequencer. 2Set the SYNC GEN parameter on the 788’s SYNC screen to SycTRK (see “Selecting the master synchronization type” on page 96). 3Set the sequencer to respond to an external clock source and make it ready to accept an external MIDI Start command. 4Return to the home screen on the 788, and press PLAY. The sequencer starts playing back at the time position corresponding to the ABS time on the 788. NOTE You do not have to start playback at the beginning of the song. If you locate to a time position on the 788, the sequencer will pick up the correct time from the MIDI SPP data output by the 788. Although it is possible to change to the bars and beats dis- play on the 788, the values displayed when using the sync track do not correspond to the bars and beats on the sequencer, unless a tempo map is entered on the 788 where the signature changes correspond to those in the sequence (note that even if the bar/beat position matches the sequencer, the tempo probably will not). You should therefore usually use the ABS time values when locating, as these are generally more meaningful location values. Tempo map You can enter the tempo map to allow the 788 to send tempo (clock) and SPP information to a MIDI device, when it is not possible to record a sync track. Another advantage of using the tempo map is that it allows you to locate to bars and beat positions on the 788, as described in “Direct location (ii)” on page 61 (using the sync track does not automatically map the bars and beats), and this is therefore a more “musi- cal” way of controlling the synchronization of the 788 with a sequencer. Entering and editing the tempo map You must enter the tempo map manually, using the procedure described here: 1Make sure playback and recording are stopped, and press the MENU key. 2Use the dial to scroll down to SYNC/ MIDI , and press ENTER.3Use the dial to highlight TEMPO MAP, and press ENTER.
11 – Synchronization–Tempo map TASCAM 788 Digital PortaStudio 99 4There is one entry automatically included in a new tempo map. The four columns in the dis- played table correspond to the following: 5Use the Ó and Á keys to move between the three editable fields, and use the dial to change the values of these fields. BAR This value cannot be changed to a value which is equal to or less than that of the entry before it, and it cannot be changed to a value which is equal to or greater than that of the entry after it. SIG You can set the time signature using the follow- ing rules: the number of beats in a bar can be set to be any number from 1 through 8, and the value of the beat can be 1 (full note (semibreve)), 2 (half-note (minim)), 4 (quarter-note (crotchet)) or 8 (eighth- note (quaver)). Values such as 7/8 are therefore possi- ble, but 11/4 is not. Tempo The maximum tempo value is 250.0, and the minimum value is 20.0. You can set the decimal part of the tempo value independently of the main part. 6Use the INSERT (MOVE) key to insert a new entry after the currently highlighted entry. 7Use the § and ¶ keys to move between entries in the tempo map table. 8Use the DELETE (SILENCE) key to delete the currently-highlighted entry. 9Press ENTER when you have entered the com- plete tempo map. NOTE The tempo map must correspond to the musical structure of the song on the sequencer. If part of the song is in 3/4, but the tempo map is all in 4/4 time, it will be impossible to relate the tempo map to the song. TIP It is not possible to enter a tempo change part of the way through a bar, and therefore you cannot do gradual speed- ing up and slowing down using a tempo map. If you need this kind of capability, we suggest that you do these tempo changes on the sequencer, and then use the sync track facility to record the tempo changes from the sequencer. The tempo map is stored as part of the song on disk and is reloaded automatically together with the song. It is therefore possible for you to make a song, com- plete with a tempo map, store it to removable media, and take it to another 788-equipped facility Using the tempo map When the tempo map has been recorded, you can use it in the following way: 1Make sure that the synchronization source for the 788 is set to INT (internal)—see “Syn- chronization master/slave setting on the 788” on page 96. The MIDI OUT of the 788 should be connected to the MIDI IN of the sequencer. 2Set the SYNC GEN parameter on the 788’s SYNC screen to CLOCK (see “Selecting the master synchronization type” on page 96). 3Set the sequencer to respond to an external clock source and SPP information and make it ready to accept an external MIDI Start com- mand from the 788.4When you start playing the 788, from the home display, the MIDI device will also start playing. 5You can use the bars and beats facility on the home display of the 788 to locate to specific bars and beats in the sequencer song. NOTEN The tempo of the sequencer playback will be determined by the tempo map on the 788, and will not be affected by the settings made on the sequencer. If you make a tempo map, this can be used as the source for the internal metronome (if the tempo does not need to change inside a bar).

11 – Synchronization–Using MTC to control a sequencer 100 TASCAM 788 Digital PortaStudio Using MTC to control a sequencer 1Make sure that the synchronization source for the 788 is set to INT (internal)—see “Syn- chronization master/slave setting on the 788” on page 96. 2Set the SYNC GEN parameter on the 788’s SYNC screen to MTC (see “Selecting the master synchronization type” on page 96). 3Set the sequencer to respond to MTC. Usually, sequencers will start automatically when MTC is received, if set up in this way. 4When you start playing the 788, the sequencer will start playing at the point located to by the 788.5Use the ABS timing method to locate to time- based points on the 788. NOTE The tempo of the sequencer is determined by the sequencer itself. If you record a track on the 788 in time with the sequencer, and then change the sequencer tempo while the sequencer is synchronized to the 788 in this way, the recorded audio track will be out of time with the MIDI tracks. Bars and beats on the 788 have no meaning when syn- chronizing in this way, unless a tempo map is manually entered on the 788. Not every sequencer or sequencer program is capable of accepting MTC. If your sequencer cannot accept MTC and use this to synchronize, you must use one of the other methods of synchronizing with the 788. Metronome The 788 also includes a metronome, which is related to the internal tempo map and takes its timing from the map. If you use the metronome, you should take care that the tempo used in the tempo map matches the tempo map of all other instruments in the setup. NOTE The metronome can only be output when the SYNC GEN option is set to CLOCK or SycTRK (“Selecting the master synchronization type” on page 96). It cannot be output when it is set to the OFF or MTC values. It can be output through the monitor speakers, or as a MIDI note. 1Make sure playback and recording are stopped, and press the MENU key. 2Use the dial to scroll down to SYNC/ MIDI , and press ENTER. 3Use the dial to highlight METRONOME, and press ENTER. 4Make sure that the SETUP tab is high- lighted. Use the cursor keys and the wheel to set the following parameters: OUTPUT Determines the kind of metronome: OFF (no metronome), INT (internal, through the MONITOR OUTPUTs and PHONES) and MIDI (a MIDI note; see below) MODE Determines when the metronome will be output: REC (recording only) or RECPLY (recording and playback) INT LEVEL Sets the level of the metronome when INT is selected as the output type (from 0 through 127). 5If you selected MIDI as the output type, use the Á key to select the MIDI tab: CH The MIDI channel on which the metronome note will be transmitted (10 is the General MIDI channel used for drums). ACC. NOTE The note on which the accented (first beat of the bar) metronome will be output. (ACC.) VELO The velocity of the accented metro- nome notes (usually louder than the other beats). NORM. NOTE The note on which non-accented metronome notes will be played. (NORM.) VELO The velocity of non-accented metronome notes.
