That is what i was saying. Would be nice if they add the option to make it behave better, when using higher frequencies.
It reminds me of the sound when using low quality mode in Dune, when using an OSC to modulate something.
I've searched the manual for info about the mod matrix in combination with OSC3 and OSC6, but couldn't find any relevant information about it, other then the 2 osc's can be used as mod sources.
