3. The modules and their functions  ^

(5) ENVELOPE GENERATOR (EG) 2

[eg2 module]
- envelope generator 2

[one] HOLD TIME
Adjusts how long EG operation will continue (remain on), even after the trigger signal has already gone from on to off (after a key has been released).
[two] DELAY TIME
Adjusts how long the beginning of the attack time will be delayed after the arrival of the trigger signal.
[three] ATTACK TIME
Adjusts how fast the envelope signal will rise to peak value after the delay time is completed.
[four] RELEASE TIME
Adjusts the time it takes for the envelope signal voltage to fall from peak value to minimum value after the trigger signal turns off or the hold time ends.
[five] TRIGGER INPUT
For the trigger signal used to control the timing of the EG. When this trigger signal's voltage drops from +2.5V (or higher) to 0V (GND) or goes from open to earth (GND), EG operation begins. When the signal returns to its original condition (+2.5V or open), the EG will maintain operation, as is, until the end of the hold time, after which the release time will elapse and the EG will stop.
[six] [seven] ENVELOPE OUTPUT
Two kinds of envelope signal are provided. Output (6) [ms50 env1] can be connected to the modulation VCA (MVCA) for delayed vibrato, or to the VCO FM IN for trigger switch controlled pitch bends. Output (7) [ms50 env2] can be used for pitch bends controlled by the KBD TRIG trigger signal every time you play a key on the keyboard.
[eight] DELAY TRIGGER OUTPUT
This jack provides a trigger signal delayed by the amount of time set by the delay time knob.

The envelope signal from VCA-2 is used for pitch bends, delayed vibrato, and other effects different from the volume changes produced through the VCA. In this HDAR system, the four knobs control the times shown in the figure below.

[eg2 envelope]
- EG-2 envelope signal

The EG-2 DELAY TRIG OUT can be used to trigger the beginning of the operation of another EG module. If you do this, the second EG module will start generating its envelope signal after being delayed for the set amount of time.

For example, you could connect the MS-10 to the MS-50, so that when you play the MS-10's keyboard, you will first get a sound from the MS-10, then, after the delay time you have programmed on the MS-50's EG-2, the MS-50's EG-1 will start to generate its ADSR envelope signal. Therefore the sound produced by the MS-50 will begin after the MS-10, and will be delayed the length of time you set on the EG-2. Of course, this is only one example. Once you get the basic idea of how the EG-2 works, you'll be able to use it for a wide variety of purposes. Experiment!
