7–1 7 - Internal effect processor The internal effect processor of the TM-D4000 allows a variety of high-quality effects to be added to the mix, while keeping the signal in the digital domain. The processor can be used either while recording, or on mixdown, as explained here. 7.1 Routing the processor The processor signal path is not limited to a single setting. The send to the processor may be routed to suit the current purposes of the project. These settings are made using the I/O SETUP screen, accessed through the DIGITAL I/O key (see 3.1, “I/O setup”). 7.1.1 Effect processor feed The EFFECT selection at the bottom of this screen allows the internal effector to be fed by either the Aux 1 and 2 send pair, or by the Aux 5 and 6 send pair. Remember that Aux 1 and 2 can be set to be pre- or post-fader, unlike any other Aux send pair. For this reason you may be using them as a foldback mix in a recording session, and you may want to use Aux sends 5 and 6 to drive the internal processor. Remember that the feed to the processor can be mon- itored using the appropriate MONITOR SELECT keys [22] . NOTE Regardless of the Aux busses which are selected as the inputs to the internal effector, the Aux buss signals are also output at the appropriate AUX OUTPUT jacks [56] in parallel with the feeds to the internal processor. 7.1.2 Processor input mode The feed to the processor can be mono (from either or both of the Aux sends) or stereo. This is set from the EFFECT screen, accessed through the EFFECT key in the Mixing section [13] (not the EFFECT key in the Library section). The knob of POD 2 in the second row is used as an rotary switch to change the input to the internal pro- cessor between the following four modes: STEREO (both Aux sends are input to the proces- sor separately), L Mono (the odd-numbered Aux send only is input in mono, R Mono (the even- numbered Aux send only is input in mono, L+R Mono (the two Aux sends are summed and pre- sented as a mono signal to the processor). 7.1.3 Effect processor input level The Aux sends control the level of the signals sent to the effect processor, which also has its own digital input level control (POD 1 in the screen above). This ranges from -¢ (full cut of the input signal) to +0dB (relative to nominal), in 128 steps using the POD 1 knob. This level is applied after the appropri- ate level selected using the Aux send master. 7.1.4 Effect processor return The I/O SETUP screen shown above is also used to use the effect processor return. There is only one module that can take the effect out- put as a return; the ST IN 2 output. Select INT EFFECT on the ST-IN 2 selection on this screen. If this setting is not made, you will not be able to hear the effects produced by the processor. The ST IN 2 module can be routed to busses, etc., and can also be sent to Aux sends 1 and 2 (if these are being used as the foldback sends).
7 - Internal effect processor—Effect types 7–2 NOTE Turn off the Aux sends from this module to the Aux busses that feed the processor. If you send from the effect return module back into the effect processor, feedback will result. This applies, of course, to all effect returns, but it is particularly easy to overlook on an internal effect processor. 7.2 Effect types The effect processor provides a number of different major effect types (some of which have sub-types), as listed here: • Reverb (Hall, Room, Live and Studio sub-types) • Gated Reverb • Delay (Stereo, Ping-pong and Multi-tap) • Chorus • Flanger • Phaser • Pitch shifter • Exciter • Dynamics (Compressor/Limiter/Expander) • De-esser The Compressor/Expander/Limiter available as an effect here is different from the dynamics processors available for each module. Settings made and stored for the effect processor in this setting cannot be recalled for channel dynamic effects, and vice versa . Likewise, the gated reverb effect uses a gate which is independent of any channel dynamics processor gate settings. 7.2.1 Selecting a basic effect type The way in which an effect is selected is from the library. The library contains a number of different preset effects, which may be used “as is” or used as starting points for experimentation and creation of new effect settings, which may be stored in the library. 1 Press the EFFECT key in the Library section [4] . Notice that the current settings for the effect send and return, as well as the currently- selected effect, are shown at the top right of this screen. 2 Make sure that the central lower part of the screen is pointing towards the right (as shown above). If it is not, turn the SHUTTLE wheel clockwise, so that it reads LIST SCROLL (not CHAR SELECT ). 3 Turn the JOG dial to scroll through the list of available effects. As the effects are high- lighted, the effect type is shown in large char- acters on the screen. Effects which are preset library effects are shown with an inverse R ( R ead-only). 4 When the effect to be recalled has been high- lighted, move the cursor to the on-screen RECALL button, and press ENTER . 7.2.2 Editing a recalled effect The EFFECT key in the Mixer section (not the EFFECT key in the Library section) is used to bring up the EFFECT screen, Up to four POD knobs in the top row may be used to set parameters for the effect, as follows. Effect type POD1 POD2 POD3 POD4 Reverb Room typeReverb timePre-delayDiffusion ValuesHall, Room, Live, Studio 0.1 – 37 (s) 0 – 250 (ms) 0 – 127 Gated reverb Gate modeGate thresholdGate timeDensity ValuesNoise gate, Gate reverb, reverse–60 – 0 (dB) 10 – 400 (ms) 0 – 127

If it is not, turn the SHUTTLE wheel clockwise, so that it reads LIST SCROLL (not CHAR SELECT ). 3 Use the JOG dial to select an unused effect memory location, or a memory location which can be overwritten with the new edited values. 4 Move the cursor to the on-screen STORE button, and press ENTER . If the memory location in which you are stor- ing the new effect already contains an effect, a popup window will ask you for confirma- tion that you want to overwrite the existing data. You cannot overwrite any of the preset read- only memories. 5 Naming of effects is done using the library screen, as described in the section on library functions.

8–1 8 - Library functions This section introduces the principles of operating the library functions for the following settings which can be edited, stored and recalled: • snapshots • dynamics processor settings • equalization settings • effect processor settings The way in which these library functions are carried out are similar for all of these, except for the snap- shot functions, which are slightly different, and are explained separately. Each library has a number of preset memory loca- tions, and a number of user memories: The preset memory locations in each library are “read-only” and cannot be overwritten by user set- tings. However, they may be recalled, and used as starting points for user settings, with the edited parameters being stored in a user location. Each library is independent of the other libraries; entries allocated for one library cannot be used by another library. Library settings can be stored “offline” using MIDI System Exclusive data dumps to MIDI data filing devices or suitably-equipped personal computers. 8.1 Snapshot memories Snapshot memories may be stored and recalled from almost any display screen. There are two dedicated keys for the store and recall of snapshots ( STORE and RECALL ) in addition to the + and – keys which are used to step through the snapshot memories. All digital audio parameters are stored as part of a snapshot library entry. However, I/O setup parame- ters, including clock source, analog audio settings (analog trim, phantom power, mic/line switching, etc.) are not stored as part of a snapshot library entry. The SNAPSHOT key is used to display the snapshot library screen, allowing renaming, etc. of snapshot library entries, as explained below. 8.1.1 Snapshot 00 This snapshot is a special case. It resets all settings to a “neutral” snapshot. All faders are set to nominal levels, and pan controls are set to center, etc. Specifically: Snapshots (all digital settings)1 pre-set “neutral” setting; 60 user settings Effector (internal effect processor)51 pre-set settings, 77 user settings EQ (channel equalization settings)20 preset settings, 80 user settings Dynamics (channel compression and gating)20 pre-set settings, 80 user settings Item Value EQ switch ON EQ gain (all bands) 0dB EQ frequency (LO/LM/LH/HI) 99 Hz/1 kHz/4 kHz/10.1 kHz EQ Q (LO/LM/LH/HI) L.SHELF/8.65/8.65/H.SHELF Fader level 0dB Cut OFF Aux send levels (all) – ¥ Aux pre/post (Aux 1,2 only ) POST Aux ON/OFF ON Pan/BAL CENTER Image width STEREO100% MONO switch STEREO Surround L-R CENTER Surround F-R F45 Surround L-R Div 100% Surround F-R Div 100% SUB level 0dB Aux master levels 0dB Aux master link OFF Aux master cut OFF Buss level 0dB Buss links OFF Buss cuts OFF Dynamics on/off OFF Dynamics type COMP Dynamics parameters THRESH/RATIO/ATTACK/ RELEASE/OUTGAIN/AUTO- MAKEUP 0dB/ – ¥: 1 /5ms/5ms/0dB/OFF Dynamics links OFF (except for ST IN 1 and 2) Dynamics trigger (not shown as link is off)BOTH Effect in 0dB Effect type REVERB Effect (as Library 1) ROOM TYPE/REV TIME/PRE DELAY/DIFFUSION HALL/3.4sec/52ms/125 Link OFF Pad level 0dB Phase switch Normal Pan gang OFF Sample delay 0sample Delay switch OFF Buss assignments No Assign
8 - Library functions—Snapshot memories 8–2 This snapshot is read-only; it cannot be overwritten with user snapshot data. 8.1.2 Recalling a snapshot The current snapshot entry is displayed at the top left of the display screen. An inverse E to the right of the snapshot number indicates that the current settings differ from those stored in the snapshot library memory. 1 Press the + or – key to change the snapshot entry displayed at the top left of the screen. The library entry number is displayed in inverse video, showing that the library entry is selected for recall, but as not yet actually been recalled. 2 Press the RECALL key to recall the library entry. NOTE When a library entry is recalled, there may be sudden jumps in level. You are advised to turn down the level of the monitoring systems before recalling a snapshot library entry. Snapshots can also be recalled from the snapshot library screen, using the on-screen RECALL but- ton, as mentioned in the section below (8.1.5, “Nam- ing a snapshot”). The on-screen UNDO key can be used to reverse the effects of the last snapshot recall. If no snapshot has been recalled before the UNDO key is pressed, an appropriate error message is displayed. Pressing and holding the SHIFT key and pressing the RECALL key will have the same effect as using the UNDO button. 8.1.3 Storing a snapshot As mentioned above, an inverse E following the snapshot number at the top right of the screen indi- cates that the current settings differ from the values stored in the library entry. To store these current settings into a library entry: 1 Press the + or – key to change the snapshot entry displayed at the top left of the screen. 2 Press the STORE key to store the settings to the library entry. If the library entry already contains data, an appropriate message appears asking if the existing data is to be overwritten. The current settings may, of course, be stored in the currently-selected library entry, overwriting the settings already stored there. If the “neutral” setting ( 00 ) is selected, a message appears on the display screen reminding you that this memory area is read- only and cannot be overwritten with other data. Snapshots can also be stored from the snapshot library screen, using the on-screen STORE button, as mentioned in the section below (8.1.5, “Naming a snapshot”). 8.1.4 Copying a snapshot Although there is no dedicated function which allows the copying of the snapshot data stored in one library entry to another library entry, it is easy to use the recall and store facilities to recall a snapshot, select another library entry, and store the recalled snapshot into the newly-selected library entry. 8.1.5 Naming a snapshot To help you remember the function of a snapshot, snapshot library entries can be named with up to 16 alphanumeric characters (and punctuation). The names of existing snapshot library entries can be used as starting points for entering new names, reducing the time and effort needed to enter names. 1 Press the SNAPSHOT key: Stereo/direct assignments (St:ON)/(Dout:OFF) Surround assignments (Srnd:ON)/(Sub:OFF) Cut group No Assign Fader group No Assign Snapshot name INITIAL-DATA Item Value
8 - Library functions—Snapshot memories 8–3 2 The SHUTTLE wheel is used to change the function of the center lower portion of the screen. In the screen shown above, this por- tion of the screen is used to manage the list of library entries. 3 The JOG dial is used to scroll through the list of entries. note that as the entries in the list are highlighted, a graphical representation of the faders is shown above the list. The fader map to the left of the screen repre- sents the current fader position, allowing comparison of a library entry with the cur- rent fader positions. 4 When the name of an entry which is to be used as the basis for a new library entry name is highlighted, the cursor keys are used to move the cursor to the on-screen · NAME button. 5 Press the ENTER key to transfer the name of the currently-selected list entry to the name editing area on the right of the screen. NOTE This procedure does not transfer the snap- shot itself; only the name of the snapshot library entry. To recall the snapshot of the cur- rently-selected list entry, use the on-screen RECALL button, or the hardware RECALL key. 6 Turn the SHUTTLE wheel counterclockwise to change the function of the center lower portion of the screen to name editing: 7 Use the JOG dial to move the cursor inside the name of the snapshot entry to be edited. 8 Use the cursor keys to move the cursor through the list of available characters, and the ENTER key to insert the highlighted character at the cursor position in the name. There are two special buttons below the list of characters: the INSERT button inserts a character at the cursor position, and the DELETE button deletes the character at the cursor position. The number keypad can also be used for direct entry of numeric characters in the name. 9 When the name has been edited, turn the SHUTTLE wheel clockwise so that the center portion of the screen controls the list scroll- ing functions. 10 Use the JOG dial to select the library entry into which the edited name will be stored. 11 Move the cursor to the on-screen NAME¸ button, and press ENTER . The edited name will now overwrite the current name (if any) of the highlighted library entry. NOTE This does not overwrite the snapshot data in the library entry, only the name of the library entry. Use the on-screen STORE button or the hardware STORE key to store snapshot data. 8.1.6 MIDI dumping and loading of snapshot library entries Snapshot data (except for snapshot 00) can be trans- mitted to MIDI devices such as sequencers, data fil- ers, etc. allowing mixer settings to be stored alongside MIDI sequences, or simply as a convenient offline storage method.
8 - Library functions—Other libraries 8–4 1 Press the MIDI/MC key [5] until the BULK screen appears: 2 Move the cursor to the SNAPSHOT checkbox, and press ENTER. Note that the other libraries can also have their data dumped and loaded together with the snap- shot library entries (i.e. more than one checkbox can be checked at the same time). 3Move the cursor to the box at the right of the checkbox. Use the JOG dial to scroll through the list of options: ALL snapshot library entries, the current settings ( Current Data ), or an individual snapshot library entry, from 01 to 60 ( Library01 – Library60). 4Make any preparations on the receiving device so that the bulk dump data can be received successfully. 5Move the cursor to the BULK DUMP but- ton, and press ENTER to start the bulk dump. As the data is being transmitted, the follow- ing popup “bargraph” appears, to indicate the progress of the operation: Note that pressing a cursor key will stop the operation. After the MIDI data has been transmitted, the popup message changes to the following: Restoring snapshot data from a MIDI bulk data trans- fer is carried out in the following way: 1Make sure that MIDI is selected as the Communication Speed in the Automation Setup screen. 2Make sure that the MIDI channel is set to be the same as the MIDI channel when the dump was made from the TM-D4000 (if this is not known, the OMNI ON function can be turned on). 3Start the transfer of the System Exclusive data from the MIDI device. NOTE If the transfer is interrupted, the TM-D4000 may be left in a “random” state. Either make the data transfer again, allowing it to com- plete, or turn the TM-D4000 off, wait a few seconds, and turn it on again. It is strongly advised that the TM-D4000 con- trols are not moved during a dump process, either in or out), as this may affect the suc- cessful trasnmission of data. Also note that after a dump transmission, if the faders have accidentally been moved during the transmis- sion, they will return to their original (pre- dump) position as soon as the dump is ended. The format of the MIDI System Exclusive bulk dump data is given in the section on MIDI. 8.2 Other libraries The other libraries: EQ, dynamics processor and effect processor, are very similar to each other in the methods used for storing and recall of library entries.
