Most reasonable thing to me seems to be when you take a symlink copy of a segment, the copy adopts the track parameters on the destination track that are in effect at the time of creation. These track parameters are segment parameters for segments that don't yet exist, and creating a linked segment here on this track is essentially the same sort of action as creating a new segment from scratch, so having this behave the same way in both cases would be intuitive, and it would be very practical from a code standpoint. All the track parameters are segment parameters too, but many of them are not editable as such. The lowest and highest playable notes for given instrument can only be edited before segments exist, and never afterwards. This has never raised any eyebrows. Taking track parameters would account for that one too, actually. Say you have a master segment where the highest playable note is two Cs above the staff, and you link it for an instrument where the highest playable note is an octave and a third lower than that. Take the highest/lowest playable notes from track parameters in effect on that track, and when you open this segment in notation, it will flag the fact that your part sounding as written does not work on the target instrument without modification. (In which case the user would have to make the linked copy into a permanent real copy (cf. the double- click to turn repeat segments into real segments procedure) and then doctor up the part to bring it into the usable range of the target instrument). > I see the potential here for more than the initial request, and I think the > avenue of altering the pitch is worth exploring, I'm just having a bit of > trouble imagining a clean interface for this. To underline what I'm getting at, this whole line of thought here doesn't involve *any* new interface. We could probably get into some questions like whether to play the part at the original pitch or transpose it suitably relative to track parameters, but this could probably just be an options dialog that appears when creating the link. You link from a flute segment to a bassoon, it detects the clef difference and asks whether to "maintain current pitch" or "transpose into suitable register" or what have you. It could be pretty nearly the same code that already exists for doing this job when you perform a clef change, with the same options. We could probably recycle 80% of that dialog, actually. -- D.
