Benny Sparra has created a free browser-based M-VAVE FM-1 patch librarian that simplifies transferring your DX-7 sounds to the mini synth.
The new FM-1 synthesizer from M-VAVE has generated a lot of interest over the past few weeks. A complete review is available in both written and video form. During testing, I noticed that the patch management is a bit odd.
Now there is a solution. Benny Sparra contacted me to say that he has created (vibe-coded) a patch librarian for it.
M-VAVE FM-1 Patch Librarian
As a reminder: the FM-1 is a compact, battery-powered FM Synthesizer with a DX-7 Synthesizer engine, and added sequencer, effects, and more. All this for around $70. Thanks to the same engine, you can import patches from the vintage hardware or Dexed plugin.
During the import procedure, you can choose between four memory slots (A-D) for your DX-7 banks. These don’t have 128 memory slots each, but rather four banks of 32 slots each. So you can import up to four DX-7 banks in the hardware.
The new patch librarian makes things a bit more flexible. In this, you have access to all four banks. So you can import a complete bank or individual sounds and create your own banks.
This feature is not currently available on the FM-1 hardware. Perhaps M-VAVE will offer a firmware update for this in the future.
Also neat is that you can change the position of the patches as well as the name.
A good tool that allows you to manage your sounds faster and more flexibly.
The new M-VAVE FM-1 patch librarian by Benny Sparra is available now for free. The hardware is available now at AliExpress or later from Amazon.

AI slop
AI made yes but it works. AI slop would be if it doesn’t work. This works.
You make / code one yourself then, without using any AI, then release it for free.
I’ll be waiting.
I also built a free, browser-based patch editor for Yamaha’s DX-family synths (reface DX, DX7, TX81Z, and more) — and since the FM-1 speaks DX7 SysEx, it now has beta support too. No install, just open it in Chrome: DXcompanion.uk. Voice editing works well; the FM-1’s onboard effects are still a work in progress since M-VAVE hasn’t published the CC numbers anywhere. Would love any feedback!
There’s a video where the MIDI impplelentatioon spec is briefly shown, let me see if I can find it in my history… here it is: https://youtu.be/vWRd1A8I3gc?t=215
yes but just the effects have MIDI CC assignements
Yup. A little disappointing but hard to complain too much given the price. Hopefully a future firmware update can expand on this capability.
MIDI CC assignements for the effects are now fully implemented. Please check it out: DXcompanion.uk
Feedback welcome!
Just took a look at your editor — VERY impressive!
Thank you very much!
You DX companion is brilliant. I load the sys files into the editor select the ones I like, then juse press save on the M1. Thank you for making this possible. 🙏
Well done this is really useful for me as I havent a clue with FM. I’m using M wave FM1.
I have found some sys files I’ve downloaded and try to load say they are not for active synth. Like I said i’m clueless.
Actually is impossible to read the patch inside the FM1 and export one of those on M-Vawe FM1 is thi correct?
