In general I'm going to have to defer to someone else who actually owns a
pro24 and knows what the mixer presents for that device.  I'll offer some
general suggestions though.

Given your description it sounds like you're seeing a "matrix mixer"
control.  Like many firewire interfaces, the pro24 allows you to mix any
input to a subset of the outputs in a rather unrestricted way.  To present
this with the least amount of screen real-estate, FFADO implemements a
matrix mixer.  This is divided into columns and rows, where (I think) the
columns represent outputs and the rows represent inputs.  Each square
represents the send level going from the respective row's input to the
column's output.

To change the value of the send, left-click-and-hold within the square.  You
can then change the level by dragging the mouse up and down.  The send's value
will be displayed as text in the middle of the square.  Release the left
mouse button when you're finished setting the value.

To date this has been the easiest way of implementing the extensive mixer
controls offered by devices such as the pro24.  Users are more than welcome
to contribute code to improve the user interface.  From those who don't
program ideas are also accepted, but given that FFADO is an all-volunteer
effort there may be considerable time before the developers get a chance to
implement ideas contributed without corresponding code.

The normal pro24 should be fine with the changes because I made them in such
a way that the pro24 will be accepted as well as the pro24dsp.  That is, the
changes I committed aren't exactly the same as those which you made: they
take into account the conditions required to accept a pro24 as well.
