Hey Oli, thanks for jumping in here! Do you have the knob mode set to snap? I'm also doing this directly on the hardware. This is how I'm experiencing the bug on my Ti2 keyboard.
1. I set the knob response mode to snap.
2. I load a patch and play some notes on the keyboard.
3. The patch sounds like all of the soft knobs are turned all the way down to 0 before I start touching any of the controls.
4. I start turning one of the soft knobs clockwise, but I don't hear any change to the sound. On the display, the stored value of the soft knob shows up in brackets as [127.]
5. Once I fully turn the knob clockwise to 127, that activates the "snap." At this point, I can turn it back counterclockwise and it will start affecting the sound. The problem with this is that I'll get an audible jump in the sound once I do start turning the knob counterclockwise. I'm clearly hearing a parameter jump from 0 to 126.
So when I load a patch, the Virus incorrectly thinks that all of the soft knobs have a stored value of 127, but the sound coming from the synth makes it clear that they actually should have a stored value of 0.
Because you have to pass the knob through the stored value to activate the snap before your knob twiddling will have an audible affect on the sound coming out of the synth, I have to turn the soft knob to 127 before I can use it to affect the sound in real time. The Virus OS thinks that I've correctly activated the snap at 127 and am now smoothly turning the knob counterclockwise back towards 0. But in fact, I'm hearing a jump from 0 126 when this happens.
