Any chance that Osc1 FTune, Osc2 FTune, OscAll FTune will be added as mod destinations? If not, could a couple mod sources for 25% and 50% of DC be added? (Using DC as source and other mod slot as destination, the minimum amount 1 with DC is still too large for fine pitch control.)
It's clunky to have to use the mod wheel to scale down the amount of modulation.
