John Parks has released the Trellis Feather dsp-G1 synthesizer over at Adafruit Learning.

“The DSP-G1 makes beautiful, classic paraphonic synth sounds, similar to the famous 1980s Roland Juno-6. You can play up to five notes at once, each with three oscillators, and you can dial in multiple wave shapes, detuning, LFO, 24db filter, ADSR envelopes for the amplifier and filter, and more!
