Fine tune as mod destination

[mikehammon]

Hi,

While programming some sounds I've found that I'm missing some finer control over pitch modulation. Even an amount of 1 is to large when trying to get some subtle pitch modulation. One way to add this possibility without messing with the current range would be to add a few modulation destinations with a smaller pitch range:  Osc1 FTune, Osc2 FTune, OscAll FTune.

Would setting a small enough amount value be what you're looking for?

No, the problem is that there's too few steps in the semitone range.

After checking again I can see there's a difference between using LFO amount directly versus using the mod matrix. If using the mod matrix the amount 1 corresponds to about 25 cent and amount 2 around 50 cent.

If using the LFO amount directly I'd say that you have about double the resolution, i.e. amount 2 is 25 cent and 4 is 50 cent.

I'd like to have the 127 values in the +- 100 cent range or something similar...

Most of the time I've used the mod wheel to control LFO amount to get those smaller fractional values.

I agree that a more fine resolution is needed. There is a not so subtle phasing that is desirable in the single digit cent range for detuning. Having only large increments sounds, well, digital...

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.

Using this as a workaround for a more gentle pitch modulation by Env3:
-> Setting Env3 attack = zero, setting sustain level around 50% rather than zero, and using a longer decay rate (to compensate for Env3 only going down to sustain 50% rather than zero)
-> Modulating Osc1Freq by the minimum-allowed amount of 1
-> Turning Osc1's fine tune down enough so that when Env3 reaches its sustain level, Osc1 will be back at its proper pitch

Really clever way to do tiny, tiny detuning stuff with gated sequencer and scaled through mod slots.
- first detune a negative fixed amount with fine tune
- insert numbers in gated sequencer, one for each voice
- scale that number through mod slot so it scales down
- set gated sequencer to advance on voice trigger so each voice get a different detune
