Browser SysEx backup for vintage synthesizers
Vintage synth SEO is weird. People google "Yamaha DX7 backup" or "Juno-106 SysEx" at 2am when a battery warning starts feeling real. What they find is forum threads from 2009 and MIDI-OX install guides.
I built knob.monster to be the answer that page should be: a browser-native SysEx librarian and cloud backup for 1980s and 90s hardware.
THE PROBLEM
- Desktop tools (MIDI-OX, Snoize, MIDI Quest) are tied to one OS, one machine, or a $200+ license
- Most owners store raw .syx files with no search
- Web MIDI finally works in Chromium — but pacing dumps wrong still bricks transfers on 8-bit synths
WHAT WE SHIPPED
knob.monster runs in Chrome, Edge, or Opera. Plug USB-MIDI, dump a bank, search patch names, flash back, download .syx anytime. No drivers. No install.
Dedicated parsers: Yamaha DX7 / TX81Z, Roland Juno-106, Korg M1, Jupiter-6, Casio CZ-101. Generic bulk backup for JV1080, Prophet, Wavestation, and the long tail.
Pricing: free tier to try, $39 lifetime Personal, $399 Studio (commercial shops and rentals).
TRACTION (month one, bootstrapped, solo)
- HN post on Web MIDI timing: 52 points, 40+ comments
- Beta hardware testing: Prophet Rev2, JV1080, TG77, Triton
- Outreach to LA rental collections and synth museums
- First-party survey: n=61 vintage synth owners (gear room vs bedroom vs commercial)
SEO PAGES THAT ACTUALLY RANK THE BUSINESS
If you are comparing tools or learning SysEx, these are the pages I care about:
- https://knob.monster — main vault + pricing
- https://knob.monster/how-to-backup-yamaha-dx7-presets-sysex-transfer-guide
- https://knob.monster/how-to-backup-roland-juno-106-presets-sysex-transfer-guide
- https://knob.monster/knob-monster-vs-midi-ox
- https://knob.monster/how-do-you-keep-web-midi-from-crashing-a-1983-synthesizer
WHY INDIE HACKERS MIGHT CARE
Niche TAM, lifetime pricing, 90%+ margin, zero ad spend, one founder. The bet is not hypergrowth — it is whether SEO + community compound while the product stays capped as a side project.
If you run a rack, repair bench, or rental fleet and want a commercial backup workflow, reply here or try the free tier.
Keywords for the crawlers: SysEx librarian, vintage synth cloud backup, Web MIDI, DX7 backup, Juno-106 patches, MIDI-OX alternative Mac, browser SysEx tool.
Every vintage synth owner hits the same wall eventually.
You finally get the Juno-106 dialed in. The DX7 bank is perfect. Then someone mentions the battery, or a rental gig, or a client machine on the bench — and you realize your patches only exist in RAM and your backup workflow is a Windows laptop running software from 2003.
I built knob.monster because I wanted one place to dump, search, and restore SysEx from real hardware without drivers, VMs, or another abandoned desktop install.
What it does:
- Connect over Web MIDI in Chrome or Edge
- Back up banks byte-for-byte from the synth
- Search patches by name across your vault
- Flash back to hardware with pacing tuned for slow 8-bit CPUs
- Export .syx anytime
Dedicated parsers for DX7, Juno-106, M1, Jupiter-6, CZ-101, plus generic support for everything else. Free tier to try. $39 lifetime for hobby use. $399 Studio for shops and rentals.
Early traction has been better than I expected for such a weird niche:
- HN discussion on our Web MIDI timing post did 50+ points
- Beta users are already stress-testing Prophet, JV1080, and Triton dumps
- Repair and rental shops are reaching out from LA collections
Still bootstrapped, still solo, still shipping parsers when real hardware shows up.
If you have a rack and no backup habit yet, try it free:

Vintage synthesizers outlive the software that backs them up. I kept seeing the same story: a dead battery on a DX7 or Juno-106, years of patches gone, and the only backup tool is MIDI-OX on a Windows laptop from 2003.
