Bert Schiettecatte based in Los Angeles California has created a new Percussa Super Signal Processor Eurorack Module which she has launched via Kickstarter this month and thanks to backers has already passed the required pledge goal to make the jump into manufacture.
The Percussa Super Signal Processor eurorack module is based on one of the fastest ARM processors available, the quad core Cortex A17, and high end ADC/DAC converters. Key Features and specifications of the Percussa Super Signal Processor :
Audio I/O
• 8 outputs via high end AKM DAC with 32 bit resolution / 192kHz sample rate (AK4458)
• 2 inputs via high end AKM ADC with 32 bit resolution / 192kHz sample rate (AK5552)
• Support for eurorack DC voltage level ranges on inputs and outputs (-5V to +5V)
• Low-noise power supplies and op-amp stages, featuring 0.1% resistors
Control Voltage I/O
• 14 inputs via industrial ADCs or via AKM audio ADCs (see “status of project” section)
• Support for eurorack DC voltage level range (-5V to +5V)
DSP Processing
• Quad core processor running at 1.8 GHz per core 32-bit SIMD and 64-bit floating point arithmetic
• 32-bit floating point ADC/DAC input / output
• Capable of running multiple software modules in parallel on multiple cores
Synthesis Engine
• Supports recording audio inputs and outputs directly to SD card for instant wavetable / sample creation or recording of live performances without the need for external software
• Supports loading your own WAV files into the Wavetable Oscillator and Sampler software modules, via the SD card (limited only by SD card size / RAM size)
• Coarse and Fine frequency controls on all Oscillators
• Comes with a set of 100+ pre-recorded samples / wavetables
• Storage and Recall of Presets and Settings with the press of a button
• Rule-based fast 2D patching
• Supports routing / mixing multiple inputs to multiple software modules
• Supports routing / mixing multiple software modules to multiple outputs
