First the demo, then the request for help -
Five dollar synth - this is the current synth engine in action driven by a five dollar kids keyboard
See it through to the end for the super smooth sounding 16Khz sine waves -
Can anyone with a musical ear come up with some arpeggios for a standalone version of the five dollar synth - the video is a clear demonstration that the musical side is not my strong point.
I Know that more people would build the project if it was standalone without having to hack a keyboard - my idea is to have a simplified version using four or five potentiometers to select from a range of arpeggios, the arpeggio playback rate, pitch and waveform - four pots and a big sound - (the fifth pot can be saved for a modulation function).
The current features of the project are -
16Mhz Sample rate, arpeggio record and play back, adjustable arpeggio rate, built in echo/delay, four waveforms, seven octave transpose.
So if you have any musical ideas and want to contribute to what should be a fast to build noisy little project, fire away - midi note numbers can be plugged straight in to the code.
