[AI] Built my own MIDI-driven VJ app for Mac (pair-programmed it with an AI) — honest feedback from actual VJs?
Hey r/vjing 👋
Quick note per the rules: [AI] = the app's code was written by pair-programming with an AI (Claude Code). The clips/visuals in the demo are my own. Nothing's for sale — just doing some research.
I'm a music producer / VJ and I ended up building my own VJ app for macOS called VidiGrid. Honest disclaimer: I'm not really a coder, so building the whole thing with an AI as my pair was a pretty surreal experience.
It started from one idea: "play the movies, play the music." I wanted to actually perform clips off a MIDI controller (I'm on an AKAI MPD218), not just launch them — so it leans more "play video like a sampler/MPC" than "timeline/layer compositor."
Where it's at right now:
- Trigger + perform clips live from MIDI pads — gate / one-shot / loop per pad, plus forward / reverse / scratch on the fly, all beat-quantizable
- Grid mode to run/switch multiple sources at once (layout can auto-reshuffle in sync with the BPM)
- A/B decks with crossfade mixing
- Audio-reactive FX locked to the beat + a bunch of other effects
- Syphon / NDI in and out, so it sits next to your existing rig (Resolume / OBS / another machine)
- Native macOS, lightweight and focused

I'm at the "is this even worth finishing?" stage, so I'd really value blunt feedback from people who actually gig:
- Does the "perform clips like an instrument" angle look useful, or does your current tool already nail it?
- What's the one feature that would make you try it in a real set?
- What are you running now, and where does it fall short live?
Not selling anything — just trying to figure out if I'm building something other VJs would want or just scratching my own itch. Tear it apart if you need to 😅
Cheers 🙏
