Ravemaker - Techno Beats is a synth bass line and drum machine sequencer that lets you hyperfocus on one bar loops. It has a full-blown monosynth, and unlocking the app adds Chorus, Tape Delay, and Reverb effects. Unlock allows users to swap in samples with advanced sequencing features: retrigger, probability, and velocity, and fills: including euclidean fills. Dwell in your rhythm and iterate pointilistically, then export your loop to audio.
