Creating slight variations in a simple beat with control voltage. All analog gear in my modular synth. Slightly "mastered" in audacity (normalization, compression, limiter).
Deep bass groove tracks were created with audacity and some great stuff i downloaded from freesound. Tags: deep bass drum 120 120bpm loop beats rhythmmy music.
Inspired by beat mapping a flock of crows chirping; i mapped my own rhythm and beat using a variety of sounds. I don't believe such an instrument exists but it sounds lovely. If you wish to use this, credit my name; otherwise enjoy.
