Issue with MIDI not being recognised by fixtures
Posted: Sat Jan 13, 2024 1:02 pm
Hi, I have a fairly urgent issue relating to MIDI being received in QLC+ for Raspbery Pi.
I have recently inherited my band's lighting setup from the person who set it up (and has now left), so my knowledge is pretty limited, as I haven't had the time to learn DMX/Rasberry Pi from scratch (although I have learn some aspects of DMX through testing process). I'll explain what I think the issue is, and underneath will explain the whole setup.
After many hours of extensive testing, I'm pretty sure the issue is somehow related to fixtures in QLC+ on the Pi - whenever I add a new fixture, it doesn't receive any input via MIDI past the current 40 channels that are being used by 4 Showtech Sunstrip Active fixtures. If I add any of the same Sunstrip fixtures, it doesn't receive data, and if I replace those original 4 fixtures, the first 40 channels no longer receive data. I can't see any settings that are any different with the original fixtures compared to the new ones added, so I'm at a loss as to why nothing seems to work past those 40 channels.
I have also checked on the Profile tab on the Input/Output section of the software, and for the 'General MIDI' profile, it seems that using the wizard there does pick up MIDI notes above D#2, where the Sunstrip channels end.
To explain the setup fully, we have a Cymatic uTrack24 sending MIDI via a MIDI-USB cable to a Raspberry Pi 4 model B, which is running QLC+. This then runs out to an Enntec Open DMX USB, which has a MIDI-XLR converter, and is then sent out to a series of 4 Showtech Suntrip Actives. We are adding in a set of 4 Abstract XLite Pros, controlled by an XDrive Lite 4.
If anyone has heard about an issue like this before and can offer some advice, it would be massively appreciated, as we're trying to get this sorted before next Saturday if at all possible
Thanks very much in advance!
