Judging by rereading this I feel the need to make sure… there are two 404s, the SP-404 and SP-404sx. I’ve seen both thrown around as if they’re interchangeable o.O

the OG 404 needs an app to compress audio to the 404’s format.

the 404sx uses wav files. it’s in the name, ‘linear wave sampler.’

so, OG 404: you need to convert samples from the 404, or sample it into the OT.

newer 404sx: you can dump the same 16 bit wav files into either machine’s card.
