Thanks for the reply,
my worries are that the pocket dial works differently than the pocket control and - fader, see here from Döpfer homepage

"POCKET DIAL is a MIDI control box with 16 endless rotary encoders - in contrast to POCKET CONTROL that is equipped with 16 rotary potentiometers. This enables a jump-less change of parameters - provided that the device or software controlled by POCKET DIAL features data feedback of the new starting data after a preset change as POCKET DIAL needs the starting values of the parameters of the new preset. Another possibility is the increment/decrement control of the parameters in question. In this case the POCKET DIAL does not “know” the absolute values of the parameters but transmits only inc/dec data to the device/software. Only devices that features the data feedback or inc/dec control should be controlled by POCKET DIAL.

For other devices we recommend [url=“http://www.doepfer.de/pc.htm”]POCKET CONTROL or [url=“http://www.doepfer.de/pf.htm”]POCKET FADER.

does this work with OT?
