Watch MidiBro in Action

What Producers Are Saying

"After three decades of producing music, I've built up a massive collection of MIDI files. MidiBro is the tool I've been waiting for. It lets me browse my MIDI files as easily as my sample library and hear them with all my custom synth sounds, just the way they were meant to be heard."

"MidiBro delivers exactly what I've been expecting from my DAW for years. And with ChordFit Mode, its utility increases immensely when working within an existing song context."

"MidiBro was an instant buy – it finally lets me quickly browse and audition my 80k+ midi files. Scanning was surprisingly fast (under a minute), and the layout fits my workflow perfectly. The AI variations are great for refining concepts. The developer has been incredibly responsive."

Scott Canada

"MidiBro is a must-have. There are a lot of sample managers for audio already, but MIDI seems to be forgotten. The wait is over. Viewing, sorting, filtering, editing, AI variations, key shifting, drum modes, DAW integration. Very complete already and rapidly progressing."

Judith Holland

"Your app really helps me to find hidden tracks in my MIDI-jungle. Works perfectly with Reaper."

Philippe France

"I'm excited to see MidiBro claim the fame it so rightfully deserves and like to see indie developers thrive when they come up with new and groundbreaking concepts in the Music Production sphere."

Jason

"Best solution to MIDI previews for Logic Pro, hands down." "The one MIDI browser to rule them all" "My prayers had been answered" "Incredibly useful and time-saving" "The big DAW boys should be watching this" "Sold. Didn't even get to the Variation Generation in the demo"

👨‍💻 The Story Behind MidiBro

Built by a Producer, for Producers

Ivo Schmidt - MidiBro Developer

Hi, I'm Ivo, a Berlin-based music producer. I kept hitting the same wall: thousands of MIDI files across dozens of folders, no way to preview them properly, and no tool that understood how producers actually work. So I built one.

Why This Matters:

  • Built to solve a real producer's problem — because I had it myself
  • Direct support from the developer (that's me!)
  • Your feedback shapes future updates
  • No corporation, no shareholders — just a solo developer who makes music

I know your workflow because it's my workflow too. MidiBro is the tool I always wished existed.
