I know that there's Kyma OSC faders for WiiTrigger, WiiButtonA, as well as Pitch, Roll, Yaw, Accel and many more (both from looking at the VCS and OSCulator).
I didn't see routing for Down, Up, Left, Right, Home, Plus, Minus, 1 and 2. Anyone know if there are controls available or should I default to using the standard !OSC_wii_1_button_down, etc. for Wiimote messages coming from OSCulator? I've tested and it works.
