Good morning, everyone.

Spencer, it sounds like you have an interesting plan for using the  
Velocity Converter. MIDI Solutions makes nice products. It will be  
interesting to see how well it can be adapted.

As for multiple MIDI applications running concurrently on a Windows  
computer: My understanding is that this is a function of the MIDI  
driver for your MIDI interface. For example, the various Yamaha USB  
MIDI interfaces and Yamaha keyboards with built-in USB interfaces  
only support just one MIDI application at a time. Edirol interfaces  
and Roland keyboards with built-in USB interfaces support multiple  
applications. I am not certain about other brands.

On the Macintosh side, OS X itself supports the use of the available  
MIDI ports by multiple applications.

Regards,
