Hi all,
Virus TI2, Osc 2, Classic Mode: For Osc 1> Osc 2 FM mod there is a choice of FM modes, the first three sourced from Osc 1 according to the manual. My question is do the first two tri-wave modes override the preselected wave of Osc 1, or are in addition to it, or what?? Then the third mode is the selected wave of Osc 1 and I am assuming it includes all Classic mode waves? Can someone explain, please?
Thanks!

The triangle waves override the wave from OSC 1. They just use the pitch of OSC 1.
IOW, only the "Wave" mode actually uses OSC 1 directly as the FM source.
Therefore you can use a classic complex waveform for OSC 1 but still have the more simple triangle available for FM.

Thanks oliAtBass! Much appreciated!
You could just pull up an Osc 1 tri-wave in the Wave fm mode too then, but I guess Access thought bi and uni polar tri's were relevant enough to have their own modes? -
The bi-polar Triangle is what you would get if you use the mode "Wave" and set OSC 1 to a triangle wave form. The uni-polar triangle for FM is different: It will result in a very different spectrum. Try the following:
- start with Init patch
- set OSC 2 to sine wave
- set OSC balance all to OSC 2 (!)
now you hear only OSC 2. You will hear the full result of the any applied FM.Now try the following:
- set OSC 1 to a sine wave
- set FM mode to wave
- change FM amount
--> listen to result- set OSC 1 to a triangle wave
- change FM amount
--> listen to result (should sound different)- set FM mode to bi-polar triangle wave
- change FM amount
--> listen to result (should sound the same)- set FM mode to uni-polar triangle wave
- change FM amount
--> listen to result (should sound very different) -
Thanks again! Knowing what to listen for really helps!
