    Musicians will love the Atmegatron because it is quick and easy to create and manipulate amazing sounds. The Atmegatron can do everything from bright square wave leads, to dirty basses, to wild sci-fi effects.

    Programmers will love it because it is built on the Arduino platform and the software is open source. This allows programmers to change or add new features and upload them to the Atmegatron.

    Synthesis Engine
    The Atmegatron uses the Atmel 328P processor, which is also at the heart of most Arduino development boards. Audio is generated by modulating a PWM output of the processor and then filtering off the modulation frequency. The Atmegatron uses analogue circuitry in the form of a steep 3rd order Chebyshev filter to maintain the high end, while still filtering off the modulation frequency.

    The Atmegtron's software uses 2 loops to create it's unique sound. One loop uses an interrupt to update the PWM output at audio frequencies. The other loop is slower and is used for everything else (MIDI input, process the wavetable, update LFOs, envelopes, arpeggiators etc). This unique synthesis method means that while the Atmegatron is clearly at home among classic Chiptune synthesizers, it also sounds highly individual.

    The structure of the Arduino code that is shipped in the Atmegatron can be tweaked as much as the user desires and re-uploaded using the Arduino development environment.
