New tool for converting DAW-arranged multi-track MIDI for Hapax use

marcastr0 · April 21, 2026, 2:52pm

Hi Squarp community!

There might be some of you out there who, like me, like to work out song arrangements in a DAW and then import the MIDI into the Hapax. I’ve found that when importing the patterns, it’s hard to keep track of the song sections (which pattern goes where, and so on). So, to make that process easier, I used Claude Code to build a CLI tool that takes a multi-track MIDI file with section markers (required for it to work as intended) and separates the patterns into their respective sections, following a naming convention that identifies tracks/instruments, patterns, and sections. It also outputs a Markdown file you can use to keep track of your arrangement while importing.

song.mid (DAW)              hapax-arrange               Hapax SD card
Intro                  ----------------->           MIDI/T01_P01_Intro.mid
Verse                                               MIDI/T01_P02_Verse.mid
Chorus                                              MIDI/T01_P03_Chorus.mid
Verse   (== Verse)                                  MIDI/T02_P01_Intro.mid
Chorus  (== Chorus)                                 ...
                                                    ARRANGEMENT.md

You can grab the tool on GitHub: GitHub - MarcAstr0/hapax-arrange: CLI that converts a DAW MIDI export into per-pattern .mid files + an import checklist for the Squarp Hapax. · GitHub

I hope this is useful to someone other than me!

A couple of screenshots / photos would be helpful, not really sure what exactly does is so based on the descriptions. Show us how exactly does a song input (DAW) / output (HPX) look like.

Here’s what the usage would look like, @RadekPilich

Here in the DAW, you have your arrangement where you organize your song into the different sections using section markers. I’m showing Reaper here, but every major DAW, as well as the MIDI standard, supports this. What the tool does is take the exported MIDI file, split each track into its corresponding patterns for each section, and save each pattern with a name that’s easy to recognize where it goes when you add it to your arrangement on the Hapax. The generated output looks like this:

,

You copy these generated files to the MIDI folder on your Hapax’s SD card, then import them into their respective tracks. This would save time in the DAW spent slicing and dicing the MIDI tracks into smaller patterns/items; just focus on your entire arrangement and not worry about patterns (I’ll admit my bias here: I come from a more traditional rock band style of songwriting rather than an electronic music background).

The tool will also output an ARRANGEMENT.md file, which is a README of sorts that tells you which tracks make up your songs, the patterns, and how they map to the generated files, to ease importing and arranging once the files are moved to the Hapax. The file looks like this:

"—" means the track is inactive in that section — leave that Hapax track on any pattern slot or mute it for that section.
