Change instrument sound in Musescore 4
The new mixer allows you to change the soundfont for the instrument, but unlike in Musescore 3, you can't change the specific sound for the instrument. In Musescore 3, you would choose all the soundfonts you want to be used in the score, then you'd select the specific sound for the instrument, but now in v4, you can only assign an entire soundfont to an instrument if that makes sense. For example, the piano tracks I used to have assigned to various synthesizers and saw waves is now locked to just piano. If there's a way to change this, I still can't find it.
