Zeppelin Design Labs Macchiato Mini Synth

   (0 reviews)

The Macchiato Mini Synth is a fun, great-sounding, easy-to-use digital synthesizer that fits in the palm of your hand. Ready-to-play or build it yourself from a fun and easy kit! Get a sleek black plastic cabinet — kit or ready-to-use — or make your own cardstock cabinet using the provided template (cardstock not included).

Requires 9V DC power. Use a battery (not included) or pick up a plug-in power supply.

If you are an Arduino enthusiast, you can hack the open-source software that runs the Macchiato, or download updates and flash them to your synth for a whole new sound.

Fun for DIY audio enthusiasts, geeks, hacks, 8-bit nerds, chip music heroes , teachers, musicians, kids, aunts, gramps and champs.

The Macchiato Mini Synth is a versatile little 8-bit synthesizer you can build and mod yourself — or get it fully assembled and ready-to-play. 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 synth kit can be completed in an evening. It’s an easy build, suitable for ages as young as 13 (with supervision).

Whether you buy the synth as a kit or ready-to-play, it comes with a template you can use to make your own cabinet from a cereal box or specialty cardstock from the craft store. Optionally, you can order a sleek black plastic cabinet, either as a simple kit or ready-to-use. Finally, with some ingenuity, you could make your own cabinet or chassis, install the synth and apply the groovy Macchiato labels.
