Hard Sync with Gen Saw Example

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?

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~…
