GMS-634EU Programmable Processor


The GMS-634EU Programmable Processor has a Teensy 3.1 processor board with a 32 bit ARM Cortex-M4 processor, USB interface, 96MHz clock, 512K of program memory and 65K of data memory. The supporting module includes two analog inputs with attenuators, two extra potentiometer-controlled voltage sources, 2 analog outputs supported by a two channel 12 bit DAC, two gate level inputs, two gate level outputs, a two channel in and out audio interface with a 24 bit 96 KHz sample rate CODEC, a standard 5 pin DIN MIDI input and output, and a 3.5mm stereo headphone output with level control.

By using the Arduino IDE with the Teensyduino add-in users of this module can download their own sketches to the module to utilize the processing power and substantially larger program space contained in this processor. A number of modular synthesizer specific sketches are available and can be downloaded and run in this module using the Teensy support libraries and some minor code modifications. In addition, libraries are provided to allow users to access the provided stereo CODEC as a high quality stereo audio input and output. The input and output jacks support -10dB line level signals.

The module can be purchased assembled or in kit form. The kit includes a Teensy 3.1 processor with pre-installed headers. The surface mount header that is used to access more of the processor I/O is also pre-installed. The CODEC board is supplied with pre-installed headers, too. The CODEC board has a socket for a mini-SD card, accessible from the rear of the module, and has been configured with SD card libraries in the Arduino environment.

The kit comes complete with all the parts and with the potentiometer leads pre-assembled. Even the solder is included. All the builder needs to assemble this kit is a narrow-tip soldering iron, long nose pliers, diagonal cutters, a small flat blade screwdriver to secure the knobs and a small or medium Phillips screwdriver. A wrench for tightening the pot and jack nuts is also recommended.

This kit includes complete instructions for assembly and is recommended for builders with intermediate kit building skills.
