Problem with Mixxx communications #2

Open jmanera opened 1 year ago

jmanera commented 1 year ago

As we told on Mixxx forum,

I have successfully gotten the controller to send messages to Mixxx correctly. But, when Mixxx sends messages to the controller, it returns these errors:

In Mixx (controller debug): Warning [Controller]: Error sending short message “traktor-s4-mk1-midify: status 0xB0 (ch 1, opcode 0xB), ctrl 0x46, val 0x00” Warning [Controller]: PortMidi error: PortMidi: `Host error’

In traktor-s4-mk1-midify: MidiInAlsa::alsaMidiHandler: unknown MIDI input error! System reports: Resource temporarily unavailable

I have tried if they are permission issues, but I get the same results. And if I send commands from traktor-s4-mk1-midify to the controller, everything works fine…

Maybe is an OS problem o miss configuration…

I hope some of you can help me. And many thanks again!

I don't think it's a configuration problem on your end. I have the same issue.

It seems that the program is having trouble handling the MIDI messages to control the vu meter LEDs for some reason. I haven't quite figured out why yet but it's certainly on my TODO list.

Fine! If you need some help to resolve it, please, let me know.

I'll try to do some testing on my own.

Thanks!

Hi! I have created a repo (based on your idea) for the Traktor Kontrol S4 Mk1 Driver for Mixxx. Please, could you take a look: https://github.com/jmanera/traktor-kontrol-s4-mk1-driver-linux.

I solved issues related to Leds, VU Meters, and Beat Loop size.

I expect that you are happy with this!

Thanks. (Sorry for my English)

The problem of this issue is related to print on the Midi In Callback, if you send some information to the console, it produces a Port Host error in the driver. Maybe errors or information.

I can solve it by sending the information to a log file.

Regards.
