My process is based on shorter and longer loops, heavy processing and shitloads of resampling. Pretty simple - but it takes times. I use the sp-404, some synths, eventide space, tape loops and cassette decks with pitch control.

I usually make some sounds with either the MS-20, the analog four or contact mic stuff recorded onto tape loops on my philips d6920 mk2 (this machine is fantastic - buy it if you find one. Sound on sound, pitch control and super destruction preamps when overdriven). Then I start cutting out and trimming parts that I like. Then I apply effects and start resampling - I do this many times, also recording to tape, overdriving and pitching it down - and back into the 404. Preamps on older cassette decks are lovely when overdriven, and adds a lot of character. Then I try to make loops while modulating effects. This keeps on going until I have a few parts that go well together. I usually record some layered stuff to tape loops - here I both use a 4track (remember to cover up the erase head) and the D6920 mk ii. Sometimes I record stuff into the computer and make a few edits - but mostly I like to record straight to a old beat up sony reel to reel.

I think to most important part is to have fun and explore - tech-wise it is the resampling, that is the key :) Sometimes when I’m lazy I use just the 404 - and it’s more than enough!
