Currently the subject of a Kickstarter campaign, the Arcano MIDI NES Chiptune Synthesizer, by Arcano Systems LLC, is an AVR-based MIDI synth that allows musicians to create Nintendo style chiptune music. Here's the story in their own words...

The Arcano MIDI NES Chiptune Synthesizer is a minimalistic, microcontroller-based synth designed to emulate the classic chiptune sound of the Nintendo Entertainment System's APU (audio processing unit.) The synthesizer's MIDI input allows musicains create NES-video-game-style chiptune music by simply connecting a MIDI keyboard or other MIDI device.

No programming is required. Each Arcano MIDI NES Chiptune Synthesizer includes a preprogrammed microcontroller; however, each synth also features a 6-pin AVR programming header, allowing programmers to flash the embedded ATmega328 microcontroller with their own custom software. The programming header enables hackers to create their own custom waveforms, envelopes, software low-frequency oscillators, and PCM samples.

Unlike many other microcontroller-based synthesizers which use internal PWM peripherals to generate weak, scratchy, low-quality audio signals, the Arcano MIDI NES Chiptune Synthesizer uses an auxiliary digital-to-analog converter chip to create a clear, high-quality audio signal.

Specifications:

• 3-note polyphony
• 1/8'' (3.5mm) jack mono audio output
• MIDI input through standard MIDI DIN connector
• 7-segment LED waveform mode indicator
