Click on the trigg "in" plug on the envelope
Generally the envelope is triggered by the keyboard. The use of a trigger delay allows you
to make the modulation appear after a determined time, as long as the note is still active.
You will obtain a different sound depending on the length of the note.
Choose the "dual trigger" option on the envelope
The starting and stopping of the sequencer can also be done using a trigger signal.
Triggered by the keyboard the sequencer is initialized on every On note. You will obtain
trigger synchronization by playing the MIDI keyboard. Triggered by a particular note, the
sequencer can appear only after an introduction for example.
