fnnkrz asked this on my YT channel too and this is what I’ve responded with:
Hey fnkrz fnkrz - Sorry to hear about the issue! I also read that about the Mode machine’s Cerebral but I’m not quite sure where the problem will be.
I do know that the LCXL works perfectly well with the Kenton host to MIDI, Bomebox, Iconnect MIDI4+ and the Sevilla soft UHM so my feeling is that the problem could potentially be somewhere with the Cerebral. Sorry I don’t have access to one to test for you.
I can most likely get hold of the older Firmware for you from work but I’m not convinced that will help.
It’s all down to the way that MIDI data transfer is set, the older firmware was set to Interrupt data transfer request. Interrupt is faster and more streamlined but not technically true class compliant, the newer firmware went back to the bulk transfer request standard which is actual true class compliant. In the real world, it still works exactly the same but means that LCXL will now work with USB hosts.
LCXL was obviously developed originally as a USB computer controller and the computer’s OS and USB controller managed the original interrupt request transfer treating it as a class compliant device. So now with the 1.2 firmware the LCXL is definitely class compliant in the true sense. I believe Interrupt was decided on as a way to make the Launchpad S a faster grid controller than the original.
To the best of my knowledge all the Host to MIDI converters need true class compliance (i.e. bulk transfer request) although I know that John from Kenton was looking at changing his box to also accept interrupt request based devices too.
As for the older firmware I can get hold of it if you want but unless the Cerebral is set to also work with interrupt request devices (which I assume it isn’t as it’s technically not class compliant)… I can’t see that actually helping you… sorry about that. If you do want to contact me direct drop me a PM on Soundcloud.com/calcutt (or get in touch here too!) and we can pick it up there.
You could also try the Novation support team, you can get hold of them from the website… they’re a good bunch :o)
I’ve also contacted our Novation support team about it and I know that Inspektor Gadget (I think that’s spelt right) is sometimes on the forum too… hopefully between us we can see if we can sort out this issue.
I did notice that the Cerebral page on the Mode Machines site is saying that the Launchpad S is tested and working with the Cerebral… this is strange as if I remember correctly the LPS is still on an interrupt request standard. so that makes me think that perhaps the older firmware could potentially help??? Hmmm!
Also did any of you adjust the templates I made for the LCXL or keep them as the download? it would be good to know.
Anyway I can definitely vouch for the Kenton, Bomebox, IconnectMIDI4+ and Sevillesoft UHM, as host to MIDI converters they all work a treat and (in my humble opinion) the LCXL is a perfect controller for the OT when it’s connected!
I know this is not a solution but I’m hopeful there is something we can do to get this working.
