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
