it disables channel selection to avoid accidential(?) double clicking  
which would result multiple preset requests. they get enabled when  
again when the preset arrived completely.
so you request a preset but dont receive a dump.

there are various ways:
- midi thru (controller port in "Open device" dialog)
- press "C" to play a single C
- use the prodatum keyboard ("K" opens the keyboard)
- use the audit button in the channel program/section

!!! use the drivers for your usb midi device (don't use the windows  
drivers, even if it "plug and played").
those will hopefully allow multiple clients.

sure, if the hub is broken. otherwise no.

i use e-mu xmidi usb devices and had to install the drivers from the e- 
mu site to get prodatum running along with cubase.
of course you know that you must connect your MP-7 bidirectionally.  
also note that some devices do not forward sysex messages when daisy  
chained. so try a direct bidirectional connection.
