Hard Sync with Gen Saw Example

    May 23 2013 | 3:09 pm
    I've got hard sync working with the gen~ blit saw. I notice that there's pulse when moving from harmonic to harmonic with the fundamental vs the sync signal. Any thoughts on how to smooth this out?

      hi peter
      please explain more.

      There's a swell in amplitude as it locks into the next harmonic. It seems logical, but undesirable, and I'm trying to figure out if I can lessen this characteristic when sweeping the slave frequency.

      Hi Peter, unfortunately I don't read very well genexpr and I find difficult to help you with the code, but I'm studying blit and hardsync. My solution starts from the consideration that in hardsync we have a series of complete and sliced waves: my idea is that the sliced one can be interpreted like a wave with higher frequency and lower amplitude. To create a smooth transition between harmonics I use a linear interpolation between two blits with differents harmonic contents, as found on the bottom of this useful tutorial:
      Mine isn't a real solution, it is more a fake simulation of hardsync, but gives decent results even with bleps and sinusoids. I hope it can be helpful

      Thanks, this is really helpful!
      Man, my hard-sync algorithm doesn't look great against saw~...
