[PD] bcr2000 and midi-feedback

I have assigned a knob on my bcr2000 to a vertical slider in pd. Under 
the sliders properties, I have set send-symbol and receive-symbol to 
"send" and "rec". I then have

[ctlin 1]
[/ 127]
[s rec]

[r send]
[* 127]
[ctlout 1]

This basically works, the upper one is receiving from the bcr and moving 
the fader in pd, the lower one is updating the display on the bcr when 
the knob is moved in pd.

The problem is that pd sends it's send-symbol, even if the fader is 
moved as a result of the receive-symbol. This means that the bcr get's 
the value right back, with a small delay, which causes the whole to be 
very reluctent to accept movements from the bcr.

I could make some logic that doesn't send the value back if it was 
received from midi, but thought I'd ask if there was a simpler solution? 
For instance is it possible to have pd's knobs *not* send it's 
send-symbol if the fader was moved as a result of a receive-symbol?

peace, love & harmony
