A generative audio patch for Patchblocks. Plays a random sequence of notes over an alternating base note and optional sub-bass.
The patch comprises three pulse (square wave) oscillators routed through a low pass filter to the analogue and digital audio outputs.
- Oscillator 1 plays a random melody with quarter notes selected from the pentatonic scale.
- Oscillator 2 also plays quarter notes and alternates between one and two octaves below the tonic note.
- Oscillator 3 plays at tempo three octaves below the tonic note.
A feedback delay can be applied to the bass (Oscillator 2). Delay time is at double tempo.
Tempo is set to 60bpm within the patch itself.
Left Knob: Set tonic note in range C4 - B4
Right Knob: Filter cut off
Left Button: Switch delay on bass in/out
Right Button: Switch sub-bass in/out
Left LED indicates delay on/off. Right LED indicates sub-bass on/off with flashing tempo.
