The Macchiato Mini Synth is a versatile 8-bit synthesizer that you can build and mod yourself! It features a built-in 13-note capacitive-touch keyboard with 2-note polyphony, MIDI IN, and eight control knobs for shaping your sound.

The Oscillator waveform can be switched between: Sine, Triangle, Saw and Square, while the octave range can switched over 4 octaves. Expression can be added with an adjustable Attack/Decay envelope and MIDI control over Pitch Bend, Modulation, Velocity, Volume and Portamento. Macchiato also features a built in low-pass filter with LFO modulation and controls for LFO Rate, Depth and Cutoff Frequency. LFO shapes available are Sine, Saw, Ramp and Square. Audio is routed to either a 3.5mm TRS or TRRS male jack or the 1″ built-in speaker.

This synth kit can be completed in a single evening – it’s an easy build and suitable for ages as young as 13 (with supervision).
