So in my attempt to try understand the multiple facets of the Octrack, I dived a bit into the recording part and due to the RAM constraint, you have basicly between 5 min (24 bits) to 8 min (16 bits) of internal recording that the OT can one shot. The next best solution is to have an external recorder and record long enough musical parts and put them back to the OT CF card via a laptop.
That was until I discovered that the Akai Force can directly write into the CF card of the OT without passing through an computer. Which other external gear/groovebox could do the same? Akai MPC One/Live/X line? Maybe the SP404 mk2? Some specific recorder with an USB mode?
