Proposal
The basic idea is an arpeggiator with 10 different presets having control over the volume harmonies being created. These presets go from simple major and minor scales to random notes creating unique sounds.
User Controls
Buttons control the presets, either on or bypass. Three knobs are also included; one to control the pitch of the starting note, the other one to choose the rate (speed) of the harmony and the third one to control the sustain of the notes, while a bigger knob controls the volume of the arpeggio. The purpose of the rate control is to be able to adjust the feel of the harmony, which could go from a slow arpeggio to a fast pattern of notes being played as background.
