Is assigning a pitch value such as C2, C3, C4 or C5 to midi middle C equals note 60 under consideration?

As things currently stand there is hardware and software that use each of the pitch values listed above as their middle C standard.

Whatever audio is played back may not represent the intent of the midi composer because the audio maybe played back at the wrong octave.

I’m a hobbyist developer and music gear enthusiast, and I wanted to share a small project I’ve been working on called Lumidi.

The idea started from something pretty simple: I have MIDI controllers sitting on my desk, and when I’m not using them they’re basically just grids of unlit LEDs.

So I thought… why not make them do something? 🙂

Lumidi is a small Windows app that detects when a supported MIDI controller is idle and turns its LEDs into animated light displays. When you start using the controller again, Lumidi gets out of the way.

It currently includes 30+ animated themes, with controls for things like animation speed and brightness.

I’ve physically tested it with:

• Novation Launchpad Mini MK3
• Novation Launch Control XL 3

There is also beta support for other Launchpad models, and I’m gradually looking at expanding device support.

I’ve tried to keep Lumidi simple: it runs in the background and brings a bit of life to MIDI controllers when they would otherwise just be sitting idle.

Lumidi is currently available for Windows through the Microsoft Store.

As this is still a new project and I’d really like to get it into the hands of more MIDI controller users, the first 1,000 downloads can get Lumidi for free from the Microsoft Store with this code:

42CGJ-X3243-CR97X-MG9M6-6X33Z

I’d be genuinely interested to hear what people who use MIDI controllers every day think about the idea — particularly which controllers you think would be worth supporting next.

Feedback, bug reports and technical questions are all very welcome.

Thanks for taking a look!

It is a desktop application I am building for musicians, keyboard players, MIDI collectors and digital music archivists who have large or messy MIDI/KAR collections.

The goal is simple: make old MIDI archives usable again.

Current focus areas include:

indexing large .mid, .midi and .kar collections

searching and filtering files

listening to files while reviewing them

organizing files into a cleaner library structure

preserving older keyboard, karaoke and floppy-era MIDI archives

I am especially interested in feedback from people who still use, collect, repair, archive or maintain MIDI files and older keyboard song libraries.

I would be very interested to hear what features or workflows would be most useful to other MIDI users and archivists.

One thing I keep running into is how differently the MIDI community uses transcription output. Some people want note-perfect MIDI for sheet music generation, others want something that captures the performance feel even at the cost of some accuracy, and others are piping it straight into a DAW where timing quantization matters more than dynamics.

Curious what this community's experience has been: what's the most frustrating gap you've hit between what audio-to-MIDI tools produce today and what you actually need the output to do? And which instrument has felt most underserved?

Taking debouncing aside and velocity, a diode matrix scan of 4 rows by 8 columns requires some logic to maintain the pressed notes, that is, once the key event occurs, the note got to be played. Some bookkeeping has to be made, reflecting the fact that it has to be remembered that it had been played. As soon as it disappears from the scan balance, it got to be muted and taken out of the momentarily active notes. etc. etc.

Is this bookkeeping algorithm available somewhere? I'm aware, that reflecting velocity adds some level of complexity.

90    22    7F    1  Bb 1 Note On
80    22    40    1  Bb 1 Note Off

Another one (FATAR 49 keyboard) sends:

90    2B    72    1  G  2 Note On               
90    2B    00    1  G  2 Note Off   

What can be said in favor of the one or the other method?
