It would be nice if i can make this work.. I have one of these things laying around & i don't know how to make this work with the Linux native version of Linux... Anyone has any ideas?

I haven’t been able to get it to work either, unfortunately it’s not class compliant. I did find a linux driver for it when googling, but it didn’t provide any sort of standard interface, it was a much lower level driver...
It might be possible to use a Windows driver wrapped, but no idea what that looks like these days... |

It would be great, maybe even wishful thinking, if the folks at Cockos would find some sort of way towards making this & perhaps more controllers work under Linux. Just thought i post this here since i happen to find one of these devices around though.

I'm quite certain the folks at cockos have read your message 😆

These things can seem unresponsive / dead until you recalibrate them.
Try Shift+Stop+F4 with the driver loaded just to be sure. |

I believe that the problem in this case is that there is no driver in the kernel for this device. There used to be one many years ago, but AFAIK it was removed and has never been added back, the kernel config option used to be: CONFIG_TRANZPORT. No idea why this happened as the kernel tends to support a massive amount of different devices, I suppose the problem is that no one that is capable of maintaining it has had any interest in doing so.
IIRC I tried to get one working a while ago, but gave up on it.. Since the code isn't in the kernel you'd have to dig up the old code and try to patch it into your kernel source, or possibly build a kernel modules out of tree. Though I'm not afraid to dig into the kernel it just seemed like too much trouble to maintain this for my system, so I took the easy way out

The driver that was available wasn't a full driver, just a very low level one that allowed you to write special commands to change lights and stuff -- a full driver would have to virtualize the hardware into a MIDI device, which would be a lot of work.

There are 3 alphatrack drivers on linux.
1. the one that was in the kernels staging for some time 2. my own driver 3. the one of Harry van Haaren All come with a user space application that creates an alsa sequencer port and converts the events comming from the driver into the related midi messages and vice versa. At least for mine i can say it works with reaper linux. But support in reaper is very limited. |

Wow, interesting. Do you have links to the drivers?
If it's an out of tree module it's probably too much of a hassle, but I might make an effort and create some dkms buildscripts for archlinux. My friend has an old one fader unit that I could borrow to test with. How well does it work with reaper's sequencer port?

linux driver
Hi Drumfix, I was wondering if you could update the link where you upload your alphatrack driver (source).
This one is already gone: https://ufile.io/dfw0r Thanks! |
