u-link Posted June 10, 2017 Report Share Posted June 10, 2017 (edited) So I got a little Arturia Minilab MK2 keyboard and a USB OTG cable as a nice compact realtime recording device (2 octaves minikeys, 2 banks of 8 backlit drumpads, 26 encoders, less than 100 bucks). After a while, especially when playing the keyboard, something goes awry and the sequencer starts to randomly select steps and overwrite their content. It stops when I go out of realtime recording, but starts again as soon as I drop into record again. Anybody has experienced something similar and maybe found a solution? The only other class compliant device I had to hand was a Beatstep, the same thing happened, too. Thanks a lot for your help! If it would work reliably, it would be an awesome combination!

Hawkeye Posted June 13, 2017 Report Share Posted June 13, 2017 Does it also happen, if you use your computer, e.g. using MIDI-OX as a translation device (thus avoiding USB OTG): Minilab -> USB Computer -> MIDI-OX -> USB MIDI Out -> SEQ MIDI In ? If it also happens using this method (stream forwarding in MIDI-OX), you could eliminate USB OTG causing the problem. If it does happen using MIDI-OX, you could also log the MIDI stream and find out what packets are being sent to the MBSEQ. Test this first, i suspect though, that it works out fine this way and that the problem might be somewhere in the USB OTG implementation, or that some strange condition arising like hitting a memory limit or dropping a packet causes it. Do you use the newest SEQ version and a STM32F4 (more RAM available)? Many greets, Peter Quote Link to comment Share on other sites More sharing options...
u-link Posted June 13, 2017 Author Report Share Posted June 13, 2017 Hi Peter, thanks for your suggestion, I will try that! Yes, STM32F4 and 0.92 firmware. It might also be some issue with the Minilab, yesterday I kinda bumped it a bit and then one of the pads seemed to be sending the note of another pad!
