hi...

i know what envelope 3 is, but can someone confirm for me what
envelopes 1 and 2 are?

i seem to remember that envelope 1 is the filter envelope and envelope
2 is the amplitude envelope but i can't find that anywhere in the 2.0
manual.

so is "E1A" in the sequencer destination the same as "filter envelope
amount"?
