But like you say there is no temporal variability possible with the command “Feedback-delay” : the effect is constant like a comb. I tried combining a few [below] thinking they may interact to change the effect with time , but no joy
(feedback-delay s 0.001 0.01)
(feedback-delay s 0.003 0.03)
(feedback-delay s 0.005 0.05)
(feedback-delay s 0.010 0.01))
What about varying the ratio that each feedback-delay contributes to the final result according to (3?) LFOs, each oscillating at a prime-number frequency so there is no repetition.
So the ratio of the notches is always changing , (not quite the same as a flanger), e.g. …
It’s an approximation of the guitarist moving about on stage getting feedback from different monitor-speakers, each with their own constant resonant-frequency.
