MPC 4000 · BackFlip
The MPC 4000 loads from a USB stick in its front port. BackFlip builds a 64-pad program around your WAVs, all four banks in one file, and saves it straight to the stick. Here is the way that works, tested on my own 4000.

From a folder of WAVs to a program on your MPC 4000.
On the 4000: Load or Save, then UTILITY (F2). In the Do field, turn the jog wheel to FULL or QUICK FORMAT, choose the removable USB device (not the hard drive), and press DO IT.
Drag WAVs onto the pads one at a time, or a whole folder at once. Four banks of 16, so up to 64 sounds per kit.
The RAM meter switches to the 4000. Set the arrow to your RAM, from the stock 16 MB up to 512 MB. Trim, fade, filter, tune, reverse and level any pad if you like.
BackFlip saves the WAVs and the .AKP program in one folder, straight onto the stick. Plug the stick into the front USB port and load the program.
One way in, and it's the simple one.
Format the stick on the 4000 first, then save from BackFlip straight to it. Tested with a 64 GB stick. If your 4000 has trouble reading a larger one, try a smaller stick.
It has to be MS-DOS (FAT) with the Master Boot Record scheme, and you erase the whole device, not just the volume. Formatting on the 4000 is simpler.
BackFlip writes 16-bit, 44.1 kHz WAVs. A stock 16 MB 4000 holds about a minute and a half of stereo sound. A fully loaded 512 MB machine holds about 51 min.
Set the MONO/STEREO switch to mono and stereo sounds fold down to mono, at half the memory.
That's the 4000 failing to read from the stick, not a problem with the files. The same files load fine from a different stick. Try another one, ideally a smaller one, formatted on the 4000.
No. The 4000 has no CompactFlash slot. Use a USB stick in the front port. The rear USB port is only for Akai's old akSys software and won't mount the drive on your computer.
Yes. Conversion has two halves: the AD going in and the DA coming out. Loading files only skips the input side. Every sound still plays back through your MPC 4000's DA and outputs, which is where a lot of that character lives.
One WAV per sound and a single .AKP program with all 64 pads across the four banks.
Both. BackFlip runs on macOS 13 or later (Intel and Apple Silicon, signed and notarized by Apple) and on Windows 10 and 11. Your purchase email has both downloads.
