imho hardware envelopes on ay sucks (i used it on msx-basic "mml" back in the 80s ) - i prefer using volume macros a lot! (which is actually the only way to have "envelopes" on sn, scc, etc.)

technically, i think that the envelope internal counter register always resets when you change the value of any frequency registers, which is what the arp effect does

I need to know how volume macros work now.
