They hope to raise $15,000 to fund the production of the plexiglass synth and they’ve already got about $6,000 in orders. You can support the production at different levels, including $300 for the fully assembled synth.
They describe the NTH synth as a ‘fun-to-use, sonically-rich, hackable music synthesizer’. It features digital oscillators, an analog low-pass filter, an integrated step sequencer, MIDI I/O, and simple, intuitive controls.
Upon successful funding, production of the NTH will begin and the entire design will be open-sourced.
Audio examples, product photos, and additional documentation can be found at the NTH website.
