Is There Any Pattern Command To Automate The Instrument Envelopes

couldnt find any info in the docs…

Short answer: no.

i guess there is something like Axy in ft2 …no ?

The only thing you can do in the pattern is prevent the envelope from being retriggered by using the Ghost note technique. (Entering a note and remove the instrument number afterwards)

If you’re really needing this, you can use a sampler instead.
