I own a studio master ma36 midi monitor, but I thought it would be great to make a modern version based on a Teensy that could handle usb as well. This is what I have so far, I have coded up notes etc and it works fine. I’m going to add a lipo battery and handy case.

Completed MIDI Analyzer, everything seems to work, the stuck LED was actually the pitchbend LED which I forgot the routine to turn it off, so that’s added now.
So it has a MIDI thru port for inline connection, but I thought about adding a MIDI out and allowing filtering of messages with a display to select what to filter.

The hardware MIDI Analyzer in a case, slightly bigger than the original MA36, but I also added a MIDI out and an OLED display and 3 buttons for future options such as midi filtering on the output port.
Hopefully it will look a bit more functional when I’ve printed a front panel.
Front panel printed, could hardly get anything to stick to this plastic box, ended up having to use a contact adhesive. Not pretty, but functional, it has a 2000mA lipo battery and usb charger built in for portability.
MIDI filtering has now been implemented…
I found another use for my MIDI analyser and filter. Today I needed a CC message generator separate from my PC, so I recoded the Analyser to be able to select a CC number 0-127 and once chosen with the select button I could then alter the value between 0-127. I needed this to map the on screen messages of the Elka-X vst to my editor, so manually setting each control 0-127 and reading the onscreen value and adding it to the editor, very boring and tedious, but worthwhile in the end. So now I think I will add an option to the Analyser to be able to generate some of the messages on the MIDI and usbMIDI outputs.

Hello Craig,
I would like to rebuild your midi analyser. The hardware is ready, but I get an error message with the software: see picture.
What am I doing wrong or have you forgotten something in the sketch?
Kind regards
Klaus
I don’t read German too well but it seems you have not installed any of the required libraries to support the compilation.

Hello,
thanks for your answer.
Reading should help 
. I forgot to change the IDE to USDBMidi. Now the software is running and I can continue building.
greetings klaus
Yeah, that did cross my mind later that if you don’t have serial & midi selected it will fail.
Also, I think I made some slight mods to the code and never published it. Some fixes for things, I will upload it shortly. Might be a little longer as we are under ballistic missile attack.
oh ha, that’s not good.
I hope the best for you.
Greetings Klaus
Updated the github repo now. I think you are the first person to build this, so good luck with it.
I’ll report back when I’m finished.
Greetings Klaus
