Just upgraded to LAMP 4.72. When holding a key down on my master keyboard, and then selecting another track, then releasing the key, the note continues to sound. the "all notes off" click doesn't stop it, nor does the "I MEAN it...all notes off" double click. Can only stop it by reselecting the orignal track and re-keying the note. this never happened in the earlier verion (3.6). Am running under OMS and FreeMidi now (due to the USB MTP AV) Any ideas? Thanks. LAMP 4.72 iBook 500 mHz MOTU MTP AV USB
