If you have a [phasor~] controlling a bunch of stuff and you wanna to have lots of different frequencies, one way of doing this is:
[phasor~ 1] | [*~ 8] | [wrap~]
which will increase the frequency by eight times. But if you wanna have a decimal number in [*~ ], say 11.7, then the last ramp of the increase will be cut at a certain point (here at 0.7, if I'm not mistaken). Someone once sent me a patch here in the list where he was doing this with [biquad~] and decimal increments were possible, but I can't find that patch anywhere, and I've no idea what coefficients I have to send to [biquad~] to achieve this. Anyone knows?
Well, I've found the patch. It's this:
[phasor~ 1] | | [0 0 1 -1 0( | / | / [biquad~] | | [0\ <- increment multiplication | | [*~ ] | [max~ 0] remove negative dirac | [fexpr~ fmod($x[0]+&y[-1], 1)] integration of the signal with a wrap
The comments are from the person who made, I'm sorry but can't remember who it is...
