Automatic ADSR mode
Automatic ADSR mode will play the ADSR envelope, as set within the menu, over and over again. Automatic
ADSR mode is selected with the modulation mode switch choosing ‘A’.
Testing automatic ADSR mode
1.
Start the modulator with the default settings
See System reset
2.
pg 31
3.
Choose a parameter to modulate on an effect unit, keyboard or MIDI controller
4.
Select ‘A’ using the mode switch and the ADSR envelop will immediately start playing.
5.
Press the on/off/calibration switch so that the ON LED lights
6.
Play a note on an instrument, and the modulation will be heard.
The modulation waveform will be using the default ADSR parameters in the system menu.
7.
Access the menu (mode on/off/calibration switch)
8.
Rotate the minimum depth control to find “Ar” (Attack rate). This sets how quickly the envelop rises.
Set this to 10 using the max depth control.
9.
Rotate the min depth control further until “dr” (decay rate) is found. This sets how quickly the
envelope will fall to the sustain level. Set this to 10 using the max depth control.
10.
Continue to rotate the minimum depth control set SL (sustain level), St (sustain time) and rr (release
rate) to zero.
11.
Rotate the min depth control to find the Sc (scale setting). This adjusts the overall time for the
envelope. Set this at 5.
12.
Play a note on the instrument being modulated and the modulation will be heard.
13.
Adjust the scale setting for the overall length required.
14.
In this example the attack and decay have both been set for 10 x 10 milliseconds. That equates to a 5
Hz vibration (5 times a second backwards and forwards). Settings less than five milliseconds can have
unpredictable but interesting results, depending on the other ADSR settings.
ADSR trigger mode
Trigger mode is used to trigger the ADSR envelope. ‘Atrg’ must be selected from the system menu for trigger
mode to function. The maximum modulating output of 127 in any modulation mode, will trigger the ADSR
envelope. The shape of the envelop is set in the menu. The stages of the envelope can be set with a
minimum time of 50 milliseconds and a maximum of 99 seconds which gives a wide range of possibilities.
When the overall envelope shape is set, the scale setting can be used to vary the time over which the entire
envelop executes.
There are three trigger modes
1.
One shot (tnno)
When the modulating output reaches the maximum depth the envelope starts and completes. If the
modulation output remains at the maximum depth, the envelope will repeat.
2.
Hold (tnnH )
When the modulating output reaches the maximum depth the envelope starts and holds at the
sustain section until the modulating output reaches maximum again, at which time the envelope
finishes sustain, begins release, and completes.
3.
Repeat (tnnr)
