We get first our look at Jeannie, a Teensy based 8-voice wavetable synthesizer designed as a DIY kit and coming along like a storm.


It’s still under development but TubeOhm has released the first video of sound examples from the prototype and it’s shaping up nicely.

Jeannie is surprisingly small with the interface based around a colour TFT screen, an encoder, a handful of buttons and four knobs. But inside we have 8 voices with 2 oscillators per voice derived from a wavetable of 64 waveforms. Each voice gets 3 LFOs, 2 envelopes and a multimode filter. There’s a unison mode that features all 16 oscillators in all their detuned gooiness. There’s cross-modulation and Ring Modulation and an internal effects chip with the usual reverb, chorus, delay and so on.

Along with the main Jeannie synthesizer there will be an additional DSP extension board to add further effects. This is based on the FV-1 and an EE-Prom so you can also write your own effects programs if you feel so inclined.

Both the synth and the DSP board will be available as DIY kits and include a little bit of surface mount soldering. Although they say they’ve created a lot of room around them to make it as easy as possible.

Lots of development still to come but it’s sounding great and ended up with an 8-voice polysynth sounds like a very cool DIY project to me. No information on pricing or release date but they say they’re on schedule.
