Exploring the Mixer - revert to previous instrument doesn't seem to work "as expected"
I noticed what seemed to be a problem with one of my scores including percussion. The intention was to have a rhythm played on an instrument, such as a cello. The whole score does include several percussion staves.
When played back it sounded as though the cello sound (without any percussion playing in those bars) was being accompanied by a triangle sound - but faintly.
In order to try to isolate this, I selected three bars, put them into a separate file, then played those bars continually in loop and tried to control the "instruments" with the mixer. i've still not identified a problem though - maybe it's my hearing or brain imagining the extra instrument.
I noticed the check box for "Drumset" in the mixer, and if that is checked, then it's interesting to hear the range of instruments and sounds which emerge. I also note that it's possible to substitute other sounds for the "cello" instrument, and this can be interesting.
There are two things which interest me though.
If the Drumset box is unset, the basic instrument does not revert back to the original Cello - but rather to Grand Piano. This may be intentional, but I did rather expect that it should revert back to whatever it was set to before.
In the Mixer sounds lists there are items such as Harmonica and Harmonica Expr. Are there real differences between these pairs of items, or is this just a confusion between a full name and something else? What is the difference - and what is that intended to provide?
OK - I'll stop my loop now - it's getting a bit much!
I've still not solved my original problem of the phantom triangle - but now I've noticed that with the Marimba sound I can hear a sort of "breathing" sound along with the marimba. Maybe these phantoms are just artefacts of the mixer and playback system.
