Studio Horns dropping notes in Logic Pro X 10.4.1
I recorded a polyphonic horn section using Studio Horns in Logic Pro X 10.4.1 and when I play it back, it keeps dropping notes or cutting them short.
It sounds fine for the first few seconds of playback and then gradually deteriorates. If I stop playback and rewind a little, the same part will play back fine, so there seems to be a problem with MIDI playback for this instrument.
I have previously run into similar problems with Synth1 by Ichiro Toda.
