Re: [ARSCLIST] One-bit files

[Craig Breaden <breaden@xxxxxxx>]

Richard,

Yes he can capture at 96/24 on the Korg, but he's still struggling
some with the interface (so this is also a question of comfort level
for him).

Next time he brings the machine in I'll do the tests you suggest and
let you know the results.

Many thanks,

Craig
