Groovesizer Alpha – first taster

June 24, 2013 · Posted in Uncategorized 

The Groovesizer is an arduino-based DIY 32-step sequencer / synth – the project is based around a custom PCB that in it current form features 4 rows of 8 tactile switches and leds – the final version will add a fifth row of buttons and leds dedicated to control functions. It features an embedded hackduino, an 8-bit DAC option, an LM386 amp output, MIDI in/out/sync and is configurable to work with some of the most popular existing arduino audio projects. Firmware can be updated from the arduino IDE, either via an AVR ISP programmer, or by flashing the chip on an arduino board and swapping it out. Furthest along in its development is the Alpha firmware which features a 3 oscillator monosynth. Other firmware will include the Bravo which borrows code from the Bleeplabs Bleepdrum https://www.sparkfun.com/products/11606 , the Charlie, based around the Illutron 4-voice wavetable synth http://www.instructables.com/id/Turn-… , and the Delta, based on the original Groovesizer with the auduino synth engine http://www.youtube.com/watch?v=9zsxWf…
The complete kit with PCB and all components will be sold for around US$100 – follow the progress on this project at http://groovesizer.com
