Eurorack delayed envelope VSL D-ENV self-cycling looping feature demo
1. Jump the GATE IN jack and D-G IN jack with a stackable.
2. Set the DELAY to maximum, and the HOLD to about 50%.
3. Use another cable plugged into the jumper at the D-G IN jack and momentarily connect to the INV OUT jack (this takes advantage of the INV OUT's resting or nominal +8V for a positive trigger feed into the D-G IN jack which in turn feeds the DELAY timer a signal to start the timing process.
4. In less than one second after initially connecting the INV OUT to the trigger cable, move it over to the D-G OUT jack before the HOLD L.E.D. goes out. If you connect before then, you should have a self-cycling D-ENV!
The above procedure is safe to perform on the D-ENV module. Any deviation from this method, including different voltages, different systems, or modifications are not recommended by VSL.
