LFO to pitch...
 
Hi !
I'm new on this forum but I'm a virus user since 13 or 14 years. I've got a TI 2 desktop.



I'd like to modulate the pitch of the oscillator 3 with an LFO. But this modulation must be just 1/2 ton.
If I set just the value 1 in the LFO 1 to osc 3 pitch, it modulates 1 ton.


Same if I do that in the mod matrix with bi or unipolar LFO 1.


Any idea to modulate pitch osc with an LFO but not more than 1/2 ton ?


Many thanks.

Hi, welcome.

By 1/2 ton, you mean 1 semitone? (1/12th of an octave?)

'Pitch' is used for semitones, but if you need something smaller you need to modulate 'Detune'. So Osc3detune, not Osc3pitch. 'Detune' gives you a range of approximately ±50 cents at each extremity.

Well... After different tests with a tuner at the output :
Modulating by a value of 1 in the mod matrix :
LFO to coarse pitch ! no less than +- 1 semitone
LFO to detune : no more than half a semitone !


I can never modulate the oscillator just 1 semitone ! :confused:

You can do it with indirect modulation, e.g.

Slot 1:
LFO -> Osc pitch
Slot 2:
10% -> Slot 1 amount

hope this helps ))

Good idea ! Gonna try ! Thanks and sorry that I did not come check here earlier !

Do you have to use those exact values btw?

Hi Calvino,

Haven't visited in a while, just saw your question.

"10%" is simply a fixed-value modulation source. I didn't specify the modulation amount - you have to tweak it by ear.
