Quad Envelope is a 4-channel AHDSR (Attack / Hold / Decay / Sustain / Release) envelope. Each channel operates completely independently. In addition to AHDSR parameters, you can also set parameters that can be selected with a switch for each channel. Use the Env select button at the bottom to select a channel before editing.

The envelope setting time can be switched from Slow / Fast / Tempo Sync with a switch. In the case of Tempo Sync, the time is set in sync with the input clock. In addition to the usual ADSR, there is also a Hold stage, so you can control the time (Hold time) to stay at 100% height before decay.

AHDSR envelope (red is Linear curve in Slow mode, blue is Exp curve in Fast mode)

"Gate" and "Loop" switch the trigger mode for each envelope. The difference in operation depending on the button state is as follows
When the Loop button is off
  • Gate button off: Performs once from the beginning to the end of the envelope (1 sustain time)
  • Gate button on: sustains while gate is high
When the Loop button is on
  • Gate button off: The loop will be retriggered by the gate input, while the loop continues (sustain time 0). It becomes a resettable unipolar LFO.
  • Gate button on: Loops only while the gate is high. Can be used as a continuous hit envelope
If you hold down the CH1 button and press one of the CH2-4 buttons, that channel and 1 channel will be linked, and the envelope of the channel linked by the CH1 gate input will also be gated.

The Quad Envelope has a clock input, and the operation of the five parameters of AHDSR can be recorded and looped for each channel in 5 steps synchronized with the clock (automation). Select the channel to record and move the slider while pressing the RECORD button. Automation can be cleared by holding CLEAR and moving the slider. The reset input is used to reset the automation sequence. The automation sequence direction can be changed for each channel.

You can also link with Varigate 8 + / 4 +, and if you share the same power bus, you can:
  • If not patched to CLK, Varigate's clock will drive automation
  • Saving presets on the Varigate side: By saving on the Varigate side, you can save the automation sequence on the Varigate side. The number of presets that can be stored at this time depends on the Varigate side.
