i doubt that Pd sends it's send-symbol....

anyhow, under the link below [1] is the abstraction that we use in our 
CUBEmixer-application in order to interact with midi (using 
behringer-sh!t) among other things.

use it like

[ctlin 1]
[sendreceive send]
[ctlout 0]

[r bla]
[ \

the abstraction depends on iemlib2 in order to have settable 
sends/receives but if you don't want this, just replace it by ordinary
