Ultrabeat features extremely fast envelopes and uncommonly powerful LFOs. Use these modulation sources to perform extreme modulations of the oscillator and filter parameters.
Try modulating as many targets as possible.
Don’t be afraid of using extreme settings.
Use a quick envelope to drive the filter to self oscillation for a fraction of a second.
Use a few LFO cycles at a much higher rate than other cycles.
Experiment with the Dirt parameter or the bit crusher.
