I am trying to troubleshoot a multi-timbral song I've composed for the Virus TI Desktop. The Virus appears to be running out of DSP power at one point in the song. At first, a particular FX sound would only play about 50% of the time. By removing some notes/parts around the time that sound is triggered, I can at least make it trigger 100% of the time- but there is often a loud pop now right before you hear the sound, which is not part of the patch itself. This only occurs about 50% of the time- so the note always plays now, but half the time it's accompanied by a loud pop.
The Virus is not clipping (max volume's just a little higher than -6db for the mixed output), so I'm almost certain this is a DSP/polyphony issue. (Also, while I do have the Virus Control plugin loaded, all audio is going out Analog Out 1+2, not the USB audio. My audio interface is a RME Fireface UFX at 44.1kHz, 24-bit, 256 samples, and I do not experience performance-related pops of this nature with any other instrument.)
Anyway, in this thread, I noticed this passage:
Zitatthere are 2 chips in the Ti and they each get one synth part; 1st chip gets part 1. 2nd gets part 2, then the 1st gets part 3, and 2nd chip gets part 4....etc. What does this mean? Simple: If you use a thick unison lead and pads on channels 1, 3 and 5 you might run out of voices, even though the 2nd chip still has DSP power to spare.
So, my question: What exactly is this saying? Does the virus assign even-numbered multi parts to one chip, and odd-numbered parts to the other? If so, wouldn't that mean the virus never used all its DSP power if you were using it mono-timbrally (only one multi part)?
I ask, because I wonder if I can minimize the DSP load during my song by shuffling the parts around. I don't want to bother with this if the Virus actually distributes the DSP load differently.
