Show HN: Melogen – Generate MIDI melodies for free

Melogen generates short melodic phrases as .mid files, no rendered audio, just notes you drop into your DAW. Free to try, no signup required.

I built this because every "AI music" tool I'd tried produces finished audio, which is the opposite of what I want when I'm stuck on a hook. I wanted something that hands me a MIDI seed I can take into Ableton/FL/Logic and shape myself.

Under the hood: - Decoder-only transformer trained on MIDI - Outputs note sequences with timing and velocity - Tuned for short, usable phrases rather than full arrangements

It's still in beta and rough in places. I'd value blunt feedback on: - Whether the generations are actually musical, or just "notes that fit a key" - MIDI handling: timing, velocity, channel assignment - What's missing before it would slot into a real workflow

Happy to get into the model, dataset, or pipeline in the comments.
