AKAI LP8 connected to axoloti's host port:
- CC messages (dials/pads) work fine
- note on/off & prgm change don't work
AKAI LP8 - Missing MIDI messages

USB Midi Controllers
Hi @paul,
Ive moved your post to a new topic, so we can discuss it... and see if we can work out why its not working fully.
first, I'm a little surprised... really it should either work or not, the note on/off are 3 byte messages and are treated (at the USB level) identically to the CCs , and pgm change messages are 2 bytes like channel pressure.
all of which I have working elsewhere. what makes it even more 'odd' is the USB midi protocol treats all messages the same (as 4 bytes), and we don't really distinguish between these (until we decode, which works the same for all devices)
can we get some more info to debug this:
- it prints some details to the console when it attaches.
- can you connect the LP8 to a computer and get a midi dump (snooze midi monitor is good on OS X) , in particular Id like to see the note on vs CC
when you use the LP8 on your computer, do CCs and note on/off all appear on the same midi port (not channel), same midi channel ... is there any configuration necessary?
do you use any kind of 'driver' on a computer? or just plain midi... (I also here would include the equivalent of 'control scripts' in Ableton.
what Im wondering is if the LP8 is some how 'configured' by the computer to tell it what to send etc.
this is not that uncommon on controllers... that they work in a 'basic' midi compatibility mode when plugged in, but certain features are 'unlocked' by sending the device CC/NRPN/Sysex messages.
Id like to get to the bottom of it, though please bare in mind, I dont have access to LP8 (and more generally cannot test every midi controller) ... but we will see what we can do.
(I could tell you how to turn on some extra debugging in the firmware, but lets see if we can avoid this)
someone has just reminded...
another interesting test, which should just work is:
connect the LPD8 to a PC/Mac and the route the midi messages directly to the Axoloti Core.
preferably not via a DAW etc, which may interpret the data and then retransmit it, what we'd like to see is the messages getting across 'as raw' as possible.
my suspicion is this will work, as there is always going to be a certain amount of unpacking/packing the midi messages, but it would prove your 'patch' and you will be easily able to monitor midi messages etc.

ok, after some tests (midi monitor dumps raw midi messages), I know why it's not working. It seems an old FW on my LP8 was the problem. I update it with the latest FW (version 00.0102) and axoloti responds to midi messages, which was send by LP8.
So you can add the AKAI LP8 to the working usb midi devices connected to axoloti's host port list and sorry for the false report.
