Private demo: iReal Pro MusicXML → Digitone II harmony prep tool

Elektron Gear Digitone/Digitone Keys

Hi everyone,
This is my first post here.

I’m Emnyeca, a Japanese jazz guitarist and metaverse performer, and I recently made a small app for my own Digitone II workflow.

The idea is to turn iRealPro MusicXML chord charts into Digitone II machine-live harmony material, so the result can be used as playable hardware material rather than a fixed backing track.

I made a short private demo video here:

I’m curious whether anyone here would be interested in this kind of jazz / fusion / ambient harmony workflow on Digitone II.

Questions and comments would be very welcome.

My English is not very strong, so detailed technical explanations may take me some time. I also prepared a public NotebookLM with my notes, which may be useful for specific questions:

Since this app uses SysEx to write patterns to Digitone II, I’m being careful and I don’t plan to make it fully public for a while.

But if anyone is interested in trying it, you are very welcome. I have a Windows-only .exe preview build.
I’ve tested it a lot on my own Digitone II, and my unit is still healthy, but this is still an early preview.

Small progress update.

I’ve been testing an experimental LPC Lead Performance with Giant Steps (one of the most difficult jazz standard songs).

In this, the program follows the chord progression of Digitone 2 and update the current Local Pitch Collection of MIDI Controller, connecting to Digitone II track. The idea is to make those tracks behave like a playable lead layer: the available notes change with each chord cell, so the performance stays harmonically connected to the tune.

The chord progression is generated from EUB Changes as SysEx data and imported natively into Digitone II. It is not AI improvisation or automatic solo generation — more like a harmony-aware performance setup.

This is still a experimental, but Giant Steps has been a useful stress test because the harmony moves so quickly. The cheap MIDI controller’s pads are so hard to press that is enough to break my fingers.
