About dynamic modulation (Dmod)

Dynamic modulation (Dmod) is a function that lets you use MIDI messages or the TRITON STUDIO’s controllers to control specific effect parameters in realtime. BPM/MIDI Sync is another function that controls effect parameters, and is used to synchronize the LFO speed of modulation-type effects or the delay time etc. of delay- type effects to the tempo of the arpeggiator or an external sequencer.

For details on each of these functions, refer to PG p.246, 248.

Setting example:

We will show how you can use dynamic modulation to control an effect parameter in realtime.

1As described in the procedure for “Effect settings for a program” (☞p.140), set “IFX1” to 049: L/C/R BPM

Delay. Verify that a delay sound is being output.

2Access the Program P8: Edit-Insert Effect, IFX1 page.

Using Dmod to change the delay level by moving the joystick away from yourself

3Set “Input Level Dmod” to +100.

4Set “Src” to JS+Y: CC#01. The delay sound will disap- pear.

The input level to the effect can be controlled by the joystick. As you move the joystick away from yourself, the delay sound will gradually increase.

Using Dmod to modify the feedback level from [SW1] key

5In P1: Edit-Basic, select the Controller Setup page,

and set the function of “SW1” to SW1 Mod.: CC#80 (Toggle).

6Return to P8. Set “Feedback Src” to SW 1: CC#80.

7Set “Amt” to +30.

When you (move the joystick away from yourself and) press the [SW1] key, the feedback level will increase, and the delay sound will continue for a longer time. The “Amt” setting specifies the feedback level that will be in effect when the [SW1] key is pressed. If “Amt” is set to –10, pressing the SW1 key will reduce the feed- back level to 0.

Using the BPM/MIDI Sync. function to synchronize the delay time to arpeggiator tempo changes.

8Set “BPM” to MIDI.

9For L, C, and R, set “Delay Base Note” and “Times” as desired.

For this example, set “Delay Base Note” to and “Times” to x1 so that the effect will be easily under- standable. The delay time will repeat at an interval of a 8th note.

0Rotate the [TEMPO] knob, and the delay time will change.

When you (push the joystick away from yourself and) press the [SW] key, the feedback level will rise, and the delays will become longer.

AWhen you turn on the ARPEGGIATOR [ON/OFF] switch, the arpeggiator will begin playing.

Select any desired arpeggio pattern. When you rotate the [TEMPO] knob, the delay time will change in syn- chronization with the changing tempo of the arpeggio.

If you rotate the [TEMPO] knob to change the tempo while the delay is sounding, noise may occur in the delay sound. This is because the delay sound becomes discontinuous, and is not a malfunction.

For some effects, you can synchronize the LFO fre- quency to the tempo. Set the effect parameters “BPM/MIDI Sync” to On, and “BPM” to MIDI. For details refer to PG p.248.
