Percussa SSP Eurorack Module Update

Sampler Scrubbing and Modulating on the Percussa SSP Eurorack Module Published on Sep 14, 2019 PERCUSSA

"New Sampler Scrubbing Features + Usability Fixes + Bugfixes

scrubbing code has been added such that if the sampler is not looping and you change start, length or Xfade, there are no glitches that can be heard. It now sounds like a tape head or vinyl record moving. Modulating start/length now is also smooth because it uses the same scrubbing code.

start/length logic has been changed so there is no more “inversing” of the from / to playback region. This should make it easier to use the sampler and to know what’s happening.

A level setting has been added per-sample so you can adjust the level for each of the 8 samples in the sampler module. This setting also allows inverting the sample playback (range is -1.0 to 1.0).

various other bugs in the sampler were fixed in the process and the code cleaned up and optimized.

New Quad SVF + Bugfixes + Optimizations

The SVF now has 4 inputs and 20 outputs (4x5). It’s now a quad-filter, which means you have 4 independent filters in one module. Each filter has 5 outputs, and the name of the outputs has been shortened to HP, LP, BP, PK and NT.

It doesn’t matter if you use 1, 2, 3 or 4 of the filters because the CPU cost is the same. Filter processing is done in parallel on the CPU now so this change does not increase CPU usage.

Cutoff / resonance mod inputs also had an issue previously where the mod signal would be scaled on the inputs, this has now been fixed. It’s possible that similar issues were present on some mod inputs of other modules, so this fix should take care of that as well."
