atmegatron complete

price : $299.00



same classic atmegatron at a new lower price. now with atmegatron v2 software preloaded and a huge selection of alternative software versions to download from the manufacturer's website.

the atmegatron complete is a revolutionary new synthesizer that takes classic 80s chiptune sounds and adds powerful new features.

musicians will love it 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.

play
8-bit monophonic midi synthesizer
unique wavetable pwm synthesis audio engine.
quick and intuitive controls, no complex menu systems

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 diagram below shows the wavetable processing chain. this is the structure of the arduino code that is shipped in the atmegatron, but this can be tweaked as much as the user desires and reuploaded using the arduino development environment.
