Clemens,
Thanks a lot. After a few pointer fixes to make it compile your code works flawlessly for both the generic as well as realtime ubuntu kernel.
I am enclosing the functioning patch.
Now I cannot feel any delay difference between usb and ice1724 midi inputs. Well done, gentlemen, thank you all.
Hi,
thanks a lot for taking care for that issue. I just tried it out by modifying the following files from the 2.6.26-rc3 kernel:
sound/pci/Kconfig (modified by hand) sound/pci/ice1712/ice1712.h (modified by hand) sound/pci/ice1712/envy24ht.h (modified by hand) sound/pci/ice1712/ice1724.c (copied from the actual Git snapshot)
I double-checked all the handmade changes, should be ok.
Midi in via "amidi -p hw:0 -d" works now without problem, but when trying to write to the device, for example by "amidi -p hw:0 -s txdata.syx" it causes an immediate crash.
That would not be a problem for me, but jackd probes all ports, and is unusable now.
Perhaps i forgot a patch, is the output working for you?
Hello Martin,
I did check the MIDI output using command
amidi -p hw:0 -S F0411042110C000000000074FF0411042110C000000
Ubuntu Studio 7.10, both -generic and -rt kernel, Audiotrak Prodigy 192, the original patch (I assume the current git version is identical).
There was no MIDI device connected to the output as I have none.
I traced if MIDI-out on Juli goes through the Xilinx CPLD, and it seemed the MIDI lines go straight to the connectors, just as on my Prodigy 192. Unfortunately, I do not have Juli available any more to test the patch.
Please could you provide more details about the crash?
Thanks,
Pavel.
