I can barely remember those days..
but...yes, created a good amount of cd-rs with it....16mb sd card goes a long way....stack some sample banks, record on the fly, with the on board effects, going into my peavey amp with on board fx, sending that into my vinyl to cd-r recorder, then played back into the sp404, usually using the isolater or (vinyl sim & dj looper, ect.) for a final mix of that backing track...
so it would be the background starting point, then id paint with it...over it...those days were pure alchemy, had micro cassettes and mic's plugged into it, sometimes id get a cassette i recorded of people on the bus talking or just me walking to the store(id have a tape recorder always) and let the whole tape run into the delay then id, take a recording of that and play it back into the delay again with another new pre recorded field cassette going into it at same time..and in those days I had no pedals....idk wtf i was doing but the sound collages turned out great.
so yeah, experiment with it.
now in days I just like recording snippits of people sayin stuff that hits a chord with me...and just now while screwin around with it I remembered you asked about it so here I am, recorded a little diddy with a particle and judder going into the 404's reverb and used a truckloud and the filter on me gristlizer to play over it with....siiiiiiiiick.
no clue what i just said....somthin about alchemy.
oh yeah, been using that distortion on the sp 404....that slicer is fuckin weird in a great way...gotta love reversing everything!
