The Yamaha AN1x Synthesizer mailing list

Hello all. I've just taken a bass sound on the AN1x and started 
fiddling around with it, as you do of an evening. I noticed that when 
you have one key pressed down, if you press another no note is 
triggered. I thought it might be due to the fact that it was in mono 
or legato mode, so I changed that to Poly and, just to avoid any 
other complications, I made sure Portamento was off and I switched 
Layer from Unison Dual to plain old Single. And yet the situation 
remains - I can play a three-note chord, say, but when I go to change 
one of the notes (with the others still pressed down), I get no noise 
from that new key.

I've fiddled around with some of the parameters, opening up the VCA 
and VCF envelopes, for example, but that doesn't alter it either.

I've probably overlooked something simple here, as usual. Any ideas, 
clever people?

Cheers,
Martin
