Harmonic resonances

Hello.
I'm trying about harmonic resonances.
I've just linked the following

I add that xmod/feedback for ping pong fx at longer delay time, but I need steps of 10 microseconds in delays for harmonic tuning, so modDelay modules would suite better (with a subtle chorusing time modulation, perhaps)

Any advice for different ways?

Try CW's Comb Filter, it's also short delays AFAIK (don't have the pulsar machine here). I think it even has keyfollow for delay times like that

Hi, at0m.
I'll try the comb filter, although at the moment I don't figure well how to patch it and how to set resonance level to increase sustain.

I've some problems tuning that stuff posted before.
The calculation of the oscillation time of a certain frequency could be 1/frequency(Hz); then multiplying the result per 1000 I could obtain the period in mS.
But setting a delay time so obtained I can hear a resonance nearly one semitone lower the choosen note...

Sorry. Patched that way, delay times are one influenced by the other, so the frequency calculation become rather complex (if it's still possible to talk about frequency, considering the double period).

But using delay time modulation it result in a really STRANGE FLANGE fx .

Does anybody can tell me more about modulation fx?

I'm not sure about this, but I know chorus create delayed copies of the input signal modulating them in pitch, flanger modulate delay time and pitch (at lower delay times), and phaser modulate just delay time (phase shifting).
Is this correct?
