Otem Rellik, developer of the Raspberry Pi FM Touch Synth or Looper is back with a new Synthesizer. Unfortunately the 4 units are already sold out but it makes sense to report because it is not mass-produced synth but an amazing homemade instrument by a musician.

Arcus is a compact drum Synthesizer & sampler that looks like a DIY version of the Teenage Engineering OP-Z. It features 4 drum voices (kick, snare, high hat, tom) and 1 sample slot. Sounds can be modified with different parameters and refined with 3 global effects. It also includes a 64-step sequencer with step automation for all parameters.

I really like this groove-box style drum Synthesizer in the beautiful wood look. I hope the developer decide to build more of it but he tells in the intro video that he will probably release the code on GitHub, so other musician can build a unit as DIY project.
