Yes it is! I'm conscious that there may be 2 separate issues are here.

1: The Midi Timing of the Virus TI as a standalone midi Synth.
2: The issue I mentioned regarding heavy patches and fast modulation/envelopes tripping up the sound.

I'm inclined to think they may be one of the same. I'm speculating here but if there are DSP resource issues as a standard midi synth this could be alleviated to an extent by loosening the sound reaction time so that lots of notes don't start exactly together. I know midi is a serial protocol and no 2 notes can sound exactly together, but by reducing reaction time would give the hardware more processing time (not good!).

With Virus Control the data has to appear out sample accurately apparently. This would disallow the theory above, but since I have experienced these modulation and envelope discrepancies, that could also be as a result of DSP resources lacking.

I'm happy to be proven wrong - in fact I hope I'm wrong, because as it stands I don't feel I can make a complex sound and have it play back correctly unless I'm using only one channel.
