Linux + Novation Launchpad + Renoise

Hi there!
I just recently dived into Linux and I am failing to get the Novation Launchpad running under Linux/Ubuntu Studio 64bit 12.10. I would like to use the LP with Renoise. Under WinXP, the LP is working fine with Renoise.

Here are some checks that I made:
uname -a
Linux HAL9000 3.5.0-17-lowlatency #18-Ubuntu SMP PREEMPT Tue Oct 9 20:04:43 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Bus 003 Device 002: ID 1235:000e Novation EMS
Bus 008 Device 002: ID 046a:0023 Cherry GmbH CyMotion Master Linux Keyboard
Bus 008 Device 003: ID 046d:c050 Logitech, Inc. RX 250 Optical Mouse

further, I installed the driver from petit volcan

However, I did not install launchpadctl as I think this software is not needed.

aconnect -i
Client 0: ‘System’ [Typ=Kernel]
0 'Timer ’
1 'Announce ’
Client 14: ‘Midi Through’ [Typ=Kernel]
0 ‘Midi Through Port-0’
Client 16: ‘Edirol DA2496’ [Typ=Kernel]
0 ‘Edirol DA2496 MIDI’

Under qjckctl the Launchpad is also not listed.

The link to “LPMIDI” by petit volcan that has been posted somewhere on this forum does not work anymore. My understanding is that this driver is replaced by the one noted above.

Any help is appreciated!
