Built for the real hardware

Every format reverse-engineered and tested on actual machines, not guesswork.

◆Batch drag & drop

Drop a single WAV on a pad, or drag a whole folder in at once. Batch drops fill the pads instantly. Pick your model, hit convert.

◆Save & reload kits

Save your pad layouts as BackFlip Project (.bfp) files and come back to them anytime. Your kits are always ready to re-export.

◆Gotek & ZuluSCSI

Direct floppy (Gotek) and ZuluSCSI export, so your kits write straight to the media your MPC reads, no extra steps.

◆Hardware-verified

Each machine's sample and program format was cracked by hand and confirmed on the actual unit. It just loads.

Getting files onto your MPC

BackFlip handles the conversion. You need a way to get the files from your computer onto your machine — here's what that looks like per model.

◆MPC 1000 / 2500 / 5000

Use a CompactFlash card, or mount your internal hard drive to drag your BackFlip files in.

◆MPC 4000

Use a USB stick, or mount your internal drive to your computer and drag your files across.

◆MPC 2000 / 2000XL / 3000

These machines use floppy or SCSI storage. Most users go with a Gotek (USB floppy emulator) or ZuluSCSI (SCSI emulator). Some also use a CompactFlash card via a SCSI-to-CF adapter. Free Gotek and ZuluSCSI setup files below.

A note from Rel

I'm an emcee and producer, and I've always loved working on the legacy MPCs and other hardware samplers. For years I wanted one simple thing: to build MPC programs on my Mac from my own samples and chops, and send them straight to the machine, without the workarounds.

This year, I finally did something about it. For all of us.

I put many months of sweat into BackFlip, reverse-engineering each format by hand and testing on the real units. Every machine, confirmed on real hardware. I hope you enjoy using it as much as I do.

Questions

Everything you need to know before you grab it.

Which Macs does BackFlip run on?

BackFlip runs on Intel Macs, and on Apple Silicon Macs (M1 and later) through Apple's Rosetta 2, which macOS offers to install automatically the first time. macOS 11 (Big Sur) or later is recommended.

The first time I open it, macOS shows a security warning. Is that normal?

Yes. Because BackFlip comes straight from me rather than the Mac App Store, macOS asks you to confirm it is safe. Right-click (or Control-click) the BackFlip icon, choose Open, then click Open again. You only need to do this once.

Does BackFlip run on Windows?

Yes — BackFlip runs on Windows 10 and Windows 11. You get both the Mac and Windows downloads in your purchase email, so you can use it on either platform.

Windows shows a SmartScreen warning when I install it. Is that normal?

Yes. Because BackFlip is distributed directly rather than through the Microsoft Store, Windows flags it on first install. Click "More info" then "Run anyway" — you only need to do this once. The app is clean.

Do I need a Gotek or ZuluSCSI?

It depends on your machine. MPC 1000, 2500, and 5000 use a CompactFlash card, or you can mount the internal hard drive directly to your computer via USB and drag files across. The MPC 4000 works the same way — USB stick in the front port, or mount the internal drive via USB. For MPC 2000, 2000XL, and 3000, most people use a Gotek (floppy emulator) or ZuluSCSI (SCSI emulator with SD card) — some also use a CompactFlash card via a SCSI-to-CF adapter. Free Gotek and ZuluSCSI setup files are available on this page.

How many computers can I use my license on?

Up to two of your own machines. Activation happens on first launch and takes a few seconds online. Moving to a new computer? Email holler@relmccoy.com and we will sort it out.

What goes in, and what comes out?

Drop in your WAV samples. BackFlip builds the native program and sample files for your chosen MPC, ready to load. You can also save your pad layouts as BackFlip Project (.bfp) files and reopen them anytime.

Will my whole kit fit on my MPC?

That depends on your machine, not on BackFlip. Your MPC's own memory and storage set the real limit, so an older unit with limited RAM (like a stock MPC 2000) can only hold so much sample data at once. BackFlip will happily build big kits, so just keep an eye on your machine's memory when you load a large one.

Which MPC models are supported?

MPC 3000, 2000, 2000XL, 1000, 2500, 4000, 5000, and 60ii. MPC 60ii support requires Vimana OS 3.15B5.

Is it a one-time purchase?

Yes. One payment, BackFlip is yours, with free updates to this version. If a future edition comes out with new features, BackFlip 1 buyers get a discount on the upgrade.

Do you offer a refund?

Yes. If BackFlip is not the right fit, email within 7 days of purchase for a full refund. You will know in minutes whether it works for your setup, so a week is plenty of time.
