Yes, that sounds reasonable to me but, but I'm not so sure about the ability to actually select a midi replacement for a track that I have recently changed to a RealTrack. Surely the software should tell me that I can't really do this rather than simply not actioning the selection.

Anyway, I thought that the ability to generate midi from a chord sequence on the chord sheet was related to the fact that style itself was a midi style. So, I can understand why a RealTrack style would know nothing about generating midi for a track on which a midi patch was assigned but surely a midi style would be able to do this?

It seems to that I really have to think about midi right at the outset if I am going to be replacing tracks. It seems that the safest possible approach is to begin with a full midi style because, once a track is changed to RT or SMT then there is no going back (or at least that's the behaviour I have come to experience.

So, in short, I thought that if the track started off as a midi track then at least I should be able to go back to it after I had changed it to an RT. BiaB implies by the Patches dialogue that I am able to this and in fact let me do all the operations and then simply not carry out the job with any indication that it can't be done.

But I do realise the limitations now.

When I was looking at the topic in the manual for midi, I came across a statement that the midi chords were generated from C7 patterns. I tried in vain to understand what that meant but I am still none the wiser.

Thanks for your help though.
