[LAU] I'm looking for something like a MIDI-signal router/converter

Hello List, on windows I used to use my Logitech Dual Action Gamepad as MIDI controller. For example to trigger the effect/modulation ratio of one or two effect to have something like a Kaospad or as Transport Controller for Cubase with the axis for moving the pointer and controlling zoom and the buttons for play, stop, record and so forth. Today I tried the same thing on linux. First of all, I have to say that it was pretty easy to set up the joystick as a midi-device, provided the gamepad itself runs under linux. In my case it was auto-detected during the openSuse 10.2 installation, so I hadn't to care about it. The tool I used is called aseqjoy by Alexander König, the developer of the TerminatorX sequencer. Compiling/Installation was quite easy and ALSA detected the Joystick/MIDI device immediatly. Unfortunately the MIDI-signals are hardcoded so it depends on the software to be triggered whether you can use the joystick on it or not. I don't know if there is something like a in-between midi-router that could route or respectively convert MIDI signals so I don't have to change the source code. Does anyone knows such a tool? -- Best regards, Sebastian.
