RED kits are currently available in the store!
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.
Currently, Groovesizer kits come in two flavors. The RED is a 16-step MIDI sequencer and granular synth.
It’s a great kit for first-time DIY builders with a low parts count and clear building instructions.
In spite of its straightforward design, the RED features a number of advanced sequencing features such as various bank and pattern playback modes, note entry quantized to preset and user defined scales, 32 memory locations for storing patterns, and MIDI sync in and out.
The current flagship model is the Groovesizer MB.
It can be transformed into a number of different instruments (sequencer, synth, drum machine, or midi controller) thanks to a growing range of firmware options.
Already available are the Alpha (32-step sequencer and 3 voice monosynth), Bravo (4-voice, 8-bit drum machine), Delta (32-step sequencer and granular synth), Golf (32-step, 12-track MIDI drum sequencer), Foxtrot (clip and scene launcher for Abelton Live), along with a template for developing one’s own firmware.
Here’s a jam with a Groovesizer RED synced to a Groovesizer Golf triggering drum sounds on a Zoom MRT-3.
The Groovesizer philosophy is twofold. The first is to provide a platform suitable for beginners to learn about the design and coding of microprocessor based electronic musical instruments. The second is to create DIY instruments with a unique voice and feature set, and that are capable of holding their own in the studio or on stage.
