Which assignment algorithm are you using for the DCA? I notice Yamaha use a simple round robin approach for assigning channels on the SFG-05 expander with FM Voicing. Recently I coded a modified round robin routine for NYYRIKKI's FM-PAC routine for the Yamaha keyboard. However what's really needed is a modified FIFO, where notes enter a queue after they are released so that the least recently used channel is used for the next note. The modified part of this routine is, where a new note is requested that is still sounding on one of the channels, you re-gate that channel rather than assigning another to the same note. Another aspect is the question of whether notes should enter the FIFO when they are pressed (key-on) or released (key-off). I would suggest that percussive tones should use the former and sustained tones the latter, in Yamaha terminology.
