I have been using Finale for 20 plus years. I have windows 10 up to date version. In the middle of composing using the using the old sound files (Garittan is usless when you want to compose for recorder consort) the tenor and alto voices will begin to have vibrator as I enter note and on playback. I have vibrato set to off. I use a Line 6 mobile keys 49. Very tired of it. The problem will stop for a while if I close the program, wait a bit, and begin again.
