Knob Monster is a new site that’s sort of like iCloud for your vintage synth patches.
The site is a browser-based SysEx librarian for your synths. It uses the Web MIDI API to connect directly to hardware like the DX7, Juno-106, Korg M1, CZ-101, Roland D-50 and more, and let you back up your synth to the cloud.
There are no drivers or desktop installs – you just plug your synth in, and Knob Monster reads the synth’s memory buffer, parses the patch names from hex and backs everything up to the cloud.
Knob Monster features dedicated name-decoding parsers for the Yamaha DX7 (and compatible synths like DX7II, TX7, TX81Z), Roland Juno-106, Korg M1, Roland Jupiter-6 (Europa-modded), and the Casio CZ series. It also has a universal Generic Scan that works with almost any vintage synthesizer by scanning raw SysEx bulk dumps for readable ASCII character arrays to extract patch names automatically.
Pricing and Availability:
Knob Monster is available now for $39.

Saw this yesterday launched at 19/month. Glad they came to their senses, sort of, but the fact they’d launch with that gives me pause as to their long term thinking.
yeah fair. we had $19/mo up for like a day while sorting licenses. dumb. it is $39 lifetime now. export syx anytime. appreciate the callout.
hello, knob ceo here
Knob buster is the next Muff Wiggler
This AI slop needs to go away
I’m going to go out on a limb and say that picture is AI generated.
I don’t mean to disparage new efforts, but presenting to us with an AI image of a dirty and non-existing synth is such a miss for me.
Like, “I will literally never visit your site”-style miss.
I just want devs to see that a lot of us actually feel this way.
fair. synth people spot fake panels instantly and we led with stock slop. pulling ai images, replacing with real hardware shots. feedback heard.
Why is everyone so fearful of their ability to make it in the world? This reminds of the CDJ sync djs vs Vinyl djs
im going on a further limb to say this entire idea was and/or can be farmed using claude by any of us. i dont think that should turn us off..I think that’s kind of magical.
Go on then. You first.
and using such an obviously ai generated image does not at all make me think they’re going to harvest all those cloud-based patches to train some ai patch generator, no, not at all……..*cough*……..
we do not train models on your patches or sell syx bruh
correct limb. image was ai. bad call for a sysex site. swapping to real desk photos.
The entire thing was definitely built with AI. The site, the images, the product itself.
ATT?CX, yeah no thanks.
Hahaha! Nice one.
I do all of this with a $5 app on my iPad.
Which one?
I kind of like that picture….Could have been from a scifi movie, or a steampunk/fantasy movie from the future. Aaaaand GO!
I do this with my iPad and a $5 app…
Come again…?
LOL! When I hit the Post button the first time nothing happened!
not paying 39 EUR for an AI generated site. Happy with my Sysex Librarian and other free alternatives.
I believe this is what the kids refer to these days as the “AI Slop”, lol.
I don’t think this would help me much, personally. I’m all ITB and I’ve already adapted to swatting at my millions of patches like they were mosquitoes. I have a big folder full of smaller ones for every instrument. Its less like wrestling a spreadsheet and more like picking colors from a palette.
The usual contemporary waste of energy and resources for useless cloud based services. Been doing this with Sysex Librarian for free for ages. **** off.
The last thing I want is to store my synth patches on someone else’s server. hard pass. Oh yeah – and take your AI Slop and shove it.
hilariously I found out about this via claude while spec’ing out new projects with it. I guess it does internally know what projects it has worked on and when I asked for similar projects that had been AI-guided it mentioned this one. Outed ?
