[Update: August 29, 2017] The successful Percussa Super Signal Processor (SSP) Eurorack module Kickstarter campaign will be over by the end of this week. The campaign hit it’s original funding goal withing a few days, and now you have just a few days left to get this powerful digital synthesis platform at the backer price of $1,500.
Early backers also get “a front row seat” in helping to determine the final software features of the SSP. See the details of this innovative Eurorack module below before visiting its Kickstarter page.
A Kickstarter campaign for the Percussa Super Signal Processor (SSP) Eurorack module
—the result of interaction with the Eurorack community since the company launched the Percussa Engine and Synthor System 8 at the Winter NAMM 2017 show—is now live.
The SSP is very similar to the Percussa Engine synthesis platform, but it comes with additional input and output connectors, featuring Eurorack-compatible voltages, and will fit in a 60HP wide space in a Eurorack system.
Only a couple of days into its Kickstarter campaign, the Percussa
SSP reached its initial fundraising goal, but there is now a new funding “stretch” goal that if reached will ensure the SSP includes MIDI Multidimensional Polyphonic Expression support.
Among the SSP’s important features include a quad-core ARM Cortex A17 1.8GHz processor, 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
* 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 off 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), which allows one to donate five Percussa SSP modules to five schools of your choice, giving students access to this powerful Eurorack module.
