[LAU] ESI RomI/O USB-Midi-Device to Rosegarden Input

how do i have to set set input(recording)-device in rosegarden to record midi from ESI RomI/O usb-midi-device? i use a yamaha dd-14 e-drum. the metronom playpack to the dd-14 works perfectly with "20:0 ESI ROMIO MIDI 1 (duplex)" (Midi-Geräte verwalten, Vorschau abspielen, Gerät -> Verbindung - sorry, my Rosegarden is german ... (i'll try to translate: playback, device, connection) at "Aufnahmegeräte" (recording devices) i can only chose "20:0 ESI ROMIO MIDI (duplex)" but this does not work. i wonder, why i can not chose "20:1 ESI ROMIO 2 (write)" as i could at "Vorschau abspielen" (playback). maybe this would be the right on, wouldn't it? what is wrong? tnx mike cx
