The VM911-A Dual Trigger Delay module is similar to the VM911 Envelope Generator, but instead of outputting dynamic envelope voltages, it simply delays voltages. With short time settings, it's useful for "double-attack" type sounds; with longer settings, it can be used to delay the onset of layered sounds.

When a gate voltage is sent to the Gate jack, the envelope generator outputs a voltage that changes dynamically according to the settings of its four stages.

Inputs, Outputs, and Controls

Delay Time- Defines the length of time the gate voltage is delayed. The time range is from 2ms to 10 seconds.

Input- Patch gate voltages to this input.

Output- The delayed gate output voltage.

Coupling Mode- Coupling allows the top and bottom sections to operate in a couple ways depending on the current setting, as follows:

  • Off: Top and bottom sections work independently.

  • Parallel: The top delay section's Input jack triggers the timing circuit for both top and bottom sections simultaneously.

  • Series: The top delay section's Input jack triggers the timing circuit for the top section, then triggers the bottom sections timing circuit when it's done. This is the same as patching the top Output to the bottom Input, and is useful for achieving longer delay times, or guaranteeing that the second output will always follow the first regardless of time settings.
