yes i am (i think)

my solution is:
- use alsa-midi (forget about /dev/midi*)
- open 2 alsa-midi ports from Pd
- connect your 2 hw-devices to the Pd's 2 alsa-midi ports (i usually 
conveniently use qjackctl for this; but you can do so by using 
[aconnect] as well)
- access the device connected to Pd's 1st port via channel1-16 and the 
device connected to the 2nd port via channel17-32
- scale at will
