I’d love “direct” recording on CF, but I absolutely don’t count on it, even if it’s possible with a RC505, recording up to 2GB, around 3H30m on a microSd card!
With OT I tested 8 recordings at the same time, directly played at different start positions, it worked perfectly. A FLEX track playing its previous recording and other recordings can even record itself!
RAM only…

So yes, @craig theoretically 1m04s max per track for 8 recordings, with free RAM.
