My Akai MPK mini does not respond well to light-control note_on messages

[alextz]

I was thrilled to find your light-control Python logic a couple hours ago. On my machine, the lights turn off if they get any note-on message, no matter what the velocity/color is.

It's actually more complex than that. The Arpeggiator ON/OFF light turns off no matter what light number is sent. And, the BANK A/B light (25) turns off only if it's green. And other odd things. But they all only turn off. I cannot turn on any light.

I don't have a DAW, so all communications with the MPK is with my own Python script. My script uses the MPK's keys, pads, and knobs without trouble. And read/writes the MPK programming.

The only ideas I have for why my lights don't work as yours do are:

1. I've not updated my firmware and you have.
2. Your DAW has initialized your MPK in some needed way.

In response to this ID request message:
mido.Message('sysex', data = [ 0x7e, 0x7f, 0x06, 0x01, ])

my MPK sends:

sysex data=(126,127,6,2,71,38,0,25,0,34,0,34,0,0,0,0,0,0,0,4,0,0,0,3,1,0,0,48,49,50,51,52)

which doesn't look very helpful. :)

Anyway, do you have any ideas what might be going on?

Thanks,

Alex

Oh foo. I just found a video that shows your script running: https://youtu.be/9KhLs2uHBk8

Completely different device.

yes sorry mate, this is a script for the "AKAI APC MINI" only, the protocol for the MPK MINI is a bit different and I would need a device to develop another script. Unfortunately I don't have any ...

I hope you will find what you need on the web

Thanks! No worries.

To note for anyone else with an Akai MPK Pro Mini looking for how to control the lights on and off:

Send "note_on channel:0 note:light_number velocity:0_or_127" to the device. Velocity zero turns off the light. 127 turns it on. Light numbers are 3..7 9..16 25..27 for the visible groups of 5, 8, and 3 lights on the device, respectively.

The picture I posted is from the Windows control program, not the device.
