Leslie-ish sound from flanger

[Processaurus]

Found a nice, albeit subtly different way to use the flanger. If you skip the internal oscillator in the flanger, but send a fast triangle LFO through the mod matrix to the flanger delay time knob, it does a different sounding thing than the regular flanger. Setting was
Delay time - 10 oclock
Regeneration - 10 oclock
Rate - 0
Width - just a tad to give some stereo width
Mix - 50/50

Sounded more leslie- like. That’s the Doppler effect, could possibly be improved by tricks people do making faux Leslie guitar effects- there’s a tremolo (amplitude modulation) aspect to the sound, as well as a tone change when the spinning horn is pointing away from you.  Seems to sound more vintage with a less bassy sound, I liked the Steiner in hi-pass mode, just cutting out the lows.

A nice article on faking the Leslie sound, I think something like figure 15 is possible with the Matrixbrute. The bit about the pitch vibrato/Doppler effect being 90 degrees of phase shift from the amplitude modulation/tremolo effect could be doable with the 2 LFO’s synced to the master clock, but using the phase shift on LFO 1 to make it shift the cycle relative to LFO 2.
