Percussa has announced the release of new software updates for the Percussa SSP Eurorack module, containing new software modules and several new software features.

Scrubbing code has been added to the sampler module.

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.

New VCA and Quad SVF modules have been introduced as well.

The new quad-VCA module can be used as a VCA or mixer. Each VCA takes an audio input (A) and a control input, and the control signal is used to scale the audio signal. Both the audio and control inputs have attenuation parameters. There is also a gain parameter per VCA, and each VCA has an individual output. Besides that there is also a SUM output which is the sum of all 4 VCA outputs, which allows you to use the VCA as a mixer.

The SVF now has 4 inputs and 20 outputs (4×5). 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.

Furthermore, the step sequencer module has been updated.

Percussa SSP step sequencer

We’ve done a massive update to the step sequencer module – we’ve added a playback window, with a start position (from). The pattern length parameter controls the length of the playback window and you can move the playback window anywhere in the 64-step pattern using the from parameter.

You also can control the direction of playback using the new Dir input and there are special inputs to be used with the new MIDI clock/start/stop/continue signals of the MIDI module (see below). Besides all this we upgrades the step sequencer from 3 modulation inputs to 14 inputs.

The MIDI module now has 4 new modulation outputs (clock, start, stop, continue). The signals can be used in any way you want and with any module you want, internally in the SSP or externally, for example to control other sequencers or modules in your rack.

Using the multichannel audio/cv streaming over USB, you can even send the signals to your DAW, and your DAW can function as the MIDI clock source (for example, connect a USB MIDI interface to the SSP’s host port, then connect this interface via MIDI cables to your computer’s MIDI interface, to receive the MIDI clock).

Besides adding new software modules and new features, Percussa also introduced various processing optimizations as well as several bug fixes.
