This is a fairly basic 1 oscillator with Amp and Filter both with individual envelopes. It has a MIDI in and an 42 button keyboard that is tuned/scaled to an Arabic mode with C as the Root. across 4 Octaves. My first patch… and post try not to beat me up too much. There is also MIDI in to control the Synth with and External Keyboard on MIDI Channel 2. Also the Audio IN is being passed through the Reverb and Panning Delay.
