Transpose / Octave Instruments
I'm using the Software MuseScore currently to orchestrate a musical (including to keyboard scores). The Keyboard Score(s) do(es) switch the sounds very often. I'm using Stafftexts to switch the channels (sounds) using a custom instrument to support many different instruments via channels.
It would be a very nice feature to be able to octave the sound using the staff text or transposing the sound
