easiest way to record long samples

I have borrowed a Moog Little Phatty that I would like to record before I have to give it back. I'd like to record about 20 seconds of each note from C1-C5. The plan is to then play those notes back in full-polyphonic later on.

I have an idea of how to get it done, but maybe you guys know of a better & quicker way.

I was thinking of buying a cheap 1in-1out USB MIDI device and set FL Studio up as Master. Go into FL piano roll and set each note to play for 20 seconds and then have the audio recorded in Sound Forge.

I was planning on doing recordings of saw, then recordings of square.

I figured I would try this before buying $2k+ for polyphonic Moog lol

thanks for any help you can share

Autosampler for Mac is what I've used to create my keygroup programs in the past, but it has been discontinued since Apple bought the company.

The advantage of using an automated app is that you can specify the notes per octave, number of notes per velocity range etc. It'll also add fades at the end of each recording, remove DC offset and bundle them into a Kontakt program which you can easily disassemble and piece together something for the MPC. I wouldn't have the patience to do it all manually now though. Life's too short.
