look under sound video and game controllers rather than drivers in control panel. that will tell you what the sound on your pc is produced by. then you can choose the driver when you load BIAB.

however, regardless of your sound card MME should work for audio playback. WAS is better as lag is negligible when recording and both WAS and MME should work regardless of your soundcard. for recording from your keyboard, turn it on and plug it in (usb i presume?) before you start BIAB and then look for the keyboard in midi input drivers.

i think you will only need an ASIO driver if you record audio - your controller is a MIDI input device. quality of midi sounds varies with the synth you use. i think you should have got Coyote WT free with BIAB and its ok. better still read Peter Gannon's post 'No brainer' om how t get the TTS1 free.
