SyncScope

Hi folks,
I had the idea of an oscilloscope synchronized to the input so that the display would be essentially static. In the analog world this was based on zero crossing. We can do better in the digital world using correlation. This SyncScope2 will grab a larger chunk of data and display a section with highest similarity (= correlation) with the last displayed data. The result is a quiet display, and you don't have to adjust trigger thresholds etc. as in the old days. If you have a synth with an animated wave display, you might want to check this out.

Have fun!

Neat, thanks MV. BTW I'll get your reverb design done within at least 3, 4 days

This is excellent Martin and immediately went into my toolbox.

The more tools we have for analysis and display the better. I make very frequent use of your Slow Scope for example and it’s been able to show stuff that I wouldn’t have been able to work out without it.

Thank you for this and all the other amazing stuff you’ve shared with us.

Cheers

Great work Martin!

Thankyou, Martin. As I mostly make effects for my bass, rather than synths, the problem of stable triggering for dynamically changing waveforms with multiple zero crossings is one that comes up rather a lot for me. Problem solved! There's something rather hypnotic about watching a bass pluck slowly morph shape, now that they're not jumping around all over the place!

Thank you all. Glad you find it useful.
