Groovesizer TB2

Groovesizers are kit-built DIY sequencers and synths. They’re open-source instruments, which means firmware for the Groovesizers can be freely examined, shared and changed in the beginner friendly Arduino IDE.

With the Quartet firmware, the TB2 is a 4 voice paraphonic wavetable synth shield for the Arduino Due development board. The TB2 features 2 oscillators per voice, an ADSR envelope, LFO, digital filter,  arpeggiator, as well as a 16-step sequencer.

For sound generation, the TB2 makes use of the pair of 12-bit DACs built into the Arduino Due’s 32 bit ARM processor. The TB2 uses an SD card for storing patches and sequences, and it also allows the user to load single cycle waveshapes for the two oscillators and the LFO.

The Attack! firmware turns the TB2 into a 6 voice drum machine with a 32-step sequencer.
