Percussa Super Signal Processor (SSP) Now on Kickstarter


Percussa's Super Signal Processor (SSP) eurorack module is now on Kickstarter here. If you haven't been following progress on the module, be sure to see the Percussa label for previous posts including demos with the prototype. The label does bring up everything featuring Percussa in reverse chronological order, so just scroll down to find them.

The following is the official press release:

"(August 4th, 2017, Los Angeles, CA) Today at 8am los angeles time our kickstarter project, the Percussa Super Signal Processor (SSP) Eurorack module, is going live.

It's the result of interaction with the eurorack community since we launced the Percussa Engine and Synthor System 8 at the Winter NAMM 2017 show in Anaheim, CA.

The SSP is very similar to the Percussa Engine, the synthesis platform we showed at the NAMM show, but comes with additional input and output connectors, featuring eurorack-compatible voltages, and will fit in a 60HP wide space in a eurorack system.

Among features of the SSP that are important to note, are a quad core ARM Cortex A17 processor @ 1.8GHz, one of the fastest ARM processors available, offering over 20,000 DMIPS of computing power (typical eurorack modules use cortex M4 or M7 processors which stay under 500 DMIPS), and high end ADC and DAC chips by AKM, supporting sample rates up to 192kHz and 32-bit resolution.



The SSP will feature 8 outputs and 16 inputs, and will support running multiple software DSP modules in parallel on multiple cores. The SSP comes with the same features of the Percussa Engine, featuring its rule-based patching system, preset storage and recall, and DSP modules such as:

Wavetable Oscillator with true 3D morphing (XYZ) and cloud features
Sampler with Layering features
LFO with multiple waveforms (sine, saw, square, triangle)
Variable Frequency Noise
DC generator
Enveloped Generator with Exponential A and DR
Waveshaper
Comb Filter
State Variable Filter
Step Sequencer
Important to note is that the Percussa SSP will support loading your own software DSP modules, which can be programmed in the C++ language. The SSP comes with the same wide-screen IPS display of 1600x480 pixels as the Percussa Engine and will feature an optimized user interface and workflow for eurorack users. The buttons and encoders will be located around the display for increased usability.

In terms of connectivity, the SSP will offer USB host and device ports for connecting a laptop for direct digital audio recording, or a USB MIDI class device for controlling the SSP. Storage wise the SSP will run of a microSD card, and a 16GB professional grade card is included in the main kickstarter pledges for the product. The SSP comes with 2GB of internal RAM which is especially useful for loading large WAV files.

One of the interesting features of the SSP is that it offers the same sampling features as the Percussa Engine, allowing you to record audio direct to SD card as WAV files, and then immediately use those WAV files as wavetables for the wavetable oscillator and sampler modules, without having to load them into software on a computer first. Everything can be done directly on the eurorack module.

In terms of pledges, the kickstarter offers normal production units, special pledges for early birds, customization options and special low serial number editions, as well as an interesting Godfather and Godmother pledge (only one of each), wich allows you to donate 5 Percussa SSP modules to 5 schools of your choice, giving students access to this powerful eurorack module.
