Yasu, there a couple of things you can do. • Hit the 'Panic'. This is in the far upper right corner of your Transport window, where you will see written "No In/No Out". When you press this it should turn the stuck notes off. If not the first time do it again. • You can also go into your Event window and scroll down to the problem bars/beats. There will most likely be a Control message 64—sustain. Control 64 will have either a 0 (zero) setting at Value for 'Off', and 127 for 'On'. You can delete or insert them where you want them. • If you use the Event Window, check each track individually to find the culprit, unless you already know. Hope it helps, Mitchell +++++++++++++++++++++++++++++++++++++++++++
