The Power of Teensy Teensy* is a readily available development board with a 32 bit processor that works with the Arduino development toolsets. It supports real time processing of high quality audio signals. There is an extensive open source library of audio signal processing code, including a tool to draw a signal processing diagram that will generate Teensy code. You can quickly develop audio processing and signal generation capabilities with very little custom code. Eurorack Ready Euroshield turns a Teensy development board into a Eurorack synthesizer module. It uses standard patch cords for input and output of standard Eurorack level audio, CV and MIDI signals. It uses the standard Eurorack power system. It mounts easily into a rack while keeping the Teensy exposed. It enables you to use the available Teensy development tools and open source code libraries to get creating quickly. Features Two audio inputs and outputs using the Eurorack -5V to +5V standard DC coupling allows audio ins and outs to be used as control voltage connections MIDI input and output via 3.5mm TRS minijacks Board design allows mounting in Eurorack while exposing the Teensy Built-in controls enable users to create a fully functioning product: Two knobs One push button 4LEDs 10 demo Sketches include sample code for filtering, reverb, and VCO. System Requirements In addition to the euroshield, here’s what you will need: Teensy Development Board* version 3.0 up to 3.6 sold by PJRC and other sources. Version 3.2 is recommended. PC or Mac for running the development tools and programming the Teensy module. Arduino development tools – open source provided by the Arduino foundation. Teensyduino development tools – open source provided by PJRC adds teensy specific functionality and a highly capable audio library. Eurorack compatible case with power and 8HP available. A USB A to microB USB cable MIDI Adapter to connect TRS Minijacks to 5 Pin DIN MIDI (optional)
