Although the Roland TR-8’s Scatter effect can sound a bit gimmicky over a regular beat, it can be a great source of glitchy percussion and effects when used purely as a sound source on its own. Ramp the knob up to explore its buzzy, granular-style tones, then quickly sweep the knob back to capture unique repeats and speed shifts.
Electronic drums are awesome sound sources for FX design. Throw a kick through a cavernous reverb to create breakdown booms; granulise hats into background textures; and reverse percussion to make rubbery, bubbling elements.
Bolster a synth line by layering a short, subtle hi-hat or rimshot over each note of the riff. This’ll add gentle front-end sharpness that may be lacking in the original synth sound.
Ring modulation and frequency shifting can be a bit too dissonant when applied to musical sounds – but that makes them ideal for processing drum machine hits and loops!
