(I'm not perfect in English, but I assume the phase drifting effect caused by
detune is called "phasing")
If 2 oscillators have constant (not modulated) detune, the phasing rate is
bigger at higher
pitch, more precisely: phasing rate relates exponentially to pitch and doubles
at each octave.
For certain sounds, a constant pitch-independent phasing rate would be
desireable.
Here is one solution that achieves it:
(drawback: it needs the modwheel or one
of the CCs W,X,Y,Z to set detune)
Oscillators: same wave, exactly (!) same pitch, no detune
Mixer: both waves at same level (63)
Modmatrix:
Mod 3: src: modwheel; amnt: +17; dest: Osc2 pitch
Mod 4: src: keyfollow; amnt: -45; dest: M3 Amount
The modwheel sets the phasing rate.
Here's another implementation that doesn't require the modwheel:
Oscillators: same wave, exactly (!) same pitch, no detune
Mixer: both waves at same level (63)
Modmatrix:
Mod 3: src: maximum; amnt: -17 (or whatever); dest: Osc1 pitch
Mod 4: src: maximum; amnt: +17 (or whatever); dest: Osc2 pitch
Mod 5: src: keyfollow; amnt: +45; dest: M3 Amount
Mod 6: src: keyfollow; amnt: -45; dest: M4 Amount
You set the phasing rate by the amounts of M3/4, both must have the same
absolute value and M3 must be negative and M4 positive.
