[linux-audio-user] serial Midi with Korg05r/w

Hello, i'm new to this list, so i hope i'm doing everything right. I want to use my Korg 05 R/W midi soundmodul via the serial tohost interface as an midi Soundmodul for midi data coming from the linux-box and (!) as an Midi Interface for my keyboard connected to the korg05r/w. In other words : the soundmodul should play my midis from computer and should transfer the midi data coming from the keyboard to the computer. the keyboard is connectet with midi-in and the computer is connected to to-host. I'm using the snd-serial-u16550 driver from alsa. After having a few problems it works, with only one Problem: I have to "restart" (turn off and turn on) my soundmodul everytime i change the program or the midifile. In some midifiles i have to restart it in the middle. In windows i didn't have this problem, so i think it havt to work unter linux, too ? Does anyone have an idea ? Marian p.s: My System : DeMuDi testing Kernel 2.6.16 selfcompiled and realtime patched starting driver with : snd-serial-u16550 port=0x2f8 irq=3
