There have been a relatively large number of OMR projects falling in and out 
of obscurity, forked, taken over, mixed with closed source and then die.

I was looking for an OMR package in portage to scan PDF sheets of music and 
then split different voice parts out into separate midi files - but if a 
single application will do the full workflow then I would be more than happy.

I understand there are a few apps by/for Apple, who seem to be the favourite 
OS for arty users, but I no longer have OSX running here or any applications 
for it.  There are also a number of other applications some of them for Linux 
- but I haven't found one yet in portage (TBH I wouldn't know its name off-
hand).

From what I read here Rosegarden will not perform OMR itself, but will import 
various file formats:
