see this thread PureData 0.49 update - #27 by thetechnobear
Q. when did you install the PD49 update? it should have been fixed yesterday. (afternoon?)
if you installed prior to that, either reinstall it, or follow my fix in the above thread.
(probably best to reinstall - so I know the fix is working 
)
personally, Id used the PD app as an example - its much clear to see that then Lemur template
you cannot set individual channels for modules - only for chains (see the original orac 1.0 video for that)
yes, the System->midi setting - only the midi device is used … channel , in / out settings are no longer used in Orac (as its has its own, more comprehensive midi options)
ch 5 = monophonic - yes, this is a bug!
ch 1 , currently is the only polyphonic channel 
2-16 are all monophonic !
MPE users might guess why
anyway, the bug is fixed in development … I just have to push it out.
what Im currently doing, is trying to wait for a few more people to install and try it, and report any other issues, and then I will release an updated beta.
