I’ve taken a few extra steps with my Audulus version of the Hordijk OSC SYNC. As much as I’d enjoyed the wide range that came with not having any tracking between the syncing and synced oscillators, I realized of course that as soon as sequencing is introduced, tracking becomes desirable/necessary. Along with a tracking switch allowing selection between full, 2/3, or 1/3 (around ‘c.v.’ = zero as a reference point), I also added an external input for the sample and hold. 1
Using external modulation with the S&H allows for some interesting effects. I’ve uploaded two demo patches to the Audulus forum: In the first the TwinPeak filter is pinged with low pulses creating a resonant percussive sounds. It’s fun to explore the different timbral results that can be obtained by simply changing the tracking setting. The second patch creates an arpeggiator like effect – with this one it can be fun to turn up the modulation dial and/or add some subsquare modulation.
It’s also possible to achieve some granular-like effects with external modulation on the S&H – as Rob Hordijk demonstrates in this video.
In the absence of normalized inputs in Audulus there’s also the output that needs to be connected to the S&H input when using the internal signal. ↩
