Fundamental in VOSIM

    Apr 27 2017 | 10:17 pm
    I have been experimenting with the VOSIM gen~ patch.
    In VOSIM, the fundamental (period) is determined by: (N x T) + M, where N is the number of pulses, T is the width of each pulse and M is the delay time before the next burst of pulses.
    How would you go about keeping the resulting frequency constant when adjusting the parameters and vice versa?

      I think you'd need to do something like this. Somehow implement this logic:
      1. start with default values ie T=2, N=4, M=2, so therefore P=10 (f=100hz)
      2. if P is changed, calculate new value of M, given the default N and T values
      3. if M<0, make it 0 and calculate new value of T
      4. if T< 0.2 decrease N by 1, recalculate T for new N
      5. if T>P/N (given M==0) then increase N by 1, recalculate T for new N
      you might be able to do this with max patching, but stuff like this would be easier to do using js

      I managed to make a javascript to do it-- hope it works for you

      I've only just seen this. I will try the js file and let you know how I get on. Thank you.

      Awesome, works great. Thanks. :-)
      Now I'm off to get morphing between rhythms and pitches while having the desired target pitch fit clearly with other stuff in Ableton. Cheers.

      glad you finally looked at it!

      Sorry to bump an old thread, but I can't see that you can message a member directly... @Floating Point are you available to chat privately? I've been playing with this again and want to see if you want to develop this further. :-)

      Are you in the Max/MSP facebook group?
