hello - i am a new DP user- i am working on a device that utilizes a Pitch Shifter- however i can't seem to get the device to enter a negative value (-1,-2 ,..-23)
the pitch shifter will due a total negative value of -23 but i can't figure out how to control this via my device. when i try to enter a negative value- it reverts back to (0). can someone give me an idea of how i should control this function. thanks for any help

click on the pitch shifter and hit the freez button in the pads window. clickon the knob and you will see in the connections window that it is connected to a CoFiPS mdl which is converting the coarse and fine tune data to a min -2147483647 to max +2147483647.

the "p" input of the pich shifter is synchronous and the output of the CoFiPS mdl is asynchronous so there is a converter automatically inserted by dp.

good luck
