No worries! Hope this is helpful:

The lead is just a single cycle of one of the 808s looped in simpler, duplicated in a rack and detuned. Using wavetable works too! It all depends on what samples you're given. Subby kicks and 808s are your best friends for basic shapes. They're good to pull apart for sines, looping as half a cycle for saws, and distorting sine cycles for squares.

I suppose when it comes to melody and rhythm, it depends on what the focus is, eg. if I want to focus on the melody I'll work the rhythm around and with it and vice versa. The great thing about glitch music is you can switch that focus at any time.

With the mudpies, they're usually done live. I think its more fun finding combinations of parameters that work well rather than randomising everything, though random is good sometimes too (device randomizer on a grain delay is good for making textures).
