one press on th keyboadr produce? I was under the impression that holding down one key would use two voices, irregardless of instrument? Some of them produce 6 or even 8... is that normal or is it MOL playing tricks on me?
You probably have layered instruments of some sort. A four-layer instrument would use 8 notes. Try moving the mod wheel and see if you get a nice crossfade crecendo. Its 4 layers from soft to loud, stacked with the Mod wheel controlling the volume from one to the next. Also, some instruments might have release tails for ambience that will hold the polyphony a little longer.
