MIDI controllers belong to the category of MIDI channel messages: the statu=
s=20
byte not only contains the message type, but also a channel number. This is=
=20
also true about the MIDI note messages, and the pitch bend, aftertouch and=
=20
all the other channel messages.

Of course there must be a channel, but it is the same if the channel number=
 is=20
associated directly to the Instrument, or it is taken indirectly from the =
=20
track properties.

Which is true, though, is that some device can recognize a different set of=
=20
controllers than some other device. That's why the controllers sets are =20
defined at the Studio, and they are associated with devices.

And talking about devices. Even if you see a device combo at the track=20
parameter box, what you really are setting with this control is one =20
instrument. Tracks have an Instrument property, but not a device property.=
=20
Devices are like a container holding a set of instruments.
