[SOLVED][MATH HELP] Map Feedback delay to freq

[vanerio]

Hi!
I have a problem that I can't solve myself. I wan´t to create a multiparameter that maps Feedback´s delay parameter to a log scaled freq, so I can link note modulators to it accordingly. in my DAW
Here I have a preset with 3 multiparameters:
1º. This is the multiparameter I am not able to map myself. I want the delay to match the freq that the multiparameter is showing. Delay milliseconds must go from 50 ms (20 Hz) to 0.05 ms (20 Khz).
2º. This is a multiparameter that maps delay to freq, but not in a log scale, so it can´t be mapped to note modulators in my DAW.
3º. This is a simple multiparameter that converts delay to linear scale, in case it helps anyone out there.

Can anyone help me with this issue?
Thank you very much in advance!

I don't fully understand what you're trying to do, but I think you might want to look at the Parameter Expression topic for MPs. Using the ability to supply a conversion expression, you can employ the several functions to convert between log and linear values, access other MP current values and a whole lot more.

No sure what topic are you refering too, could you please be more specific?

What I want to do is that multiparameter 1 sets the feedbacks´s delay to the milliseconds corresponding to each frequency.
For example:
20 Hz = 50 ms
20000 Hz = 0.05 ms
So I want to map the entire frequency range of multiparameter 1.

I believe this is what you were looking for. Enter a frequency in the multiparameter and you will get a delay length of one cycle of that frequency, e.g.
100 Hz = 10 ms
1000 Hz = 1 ms
20/20kHz = 50 / 0.05 ms
