I think this thread is describing my problem (Windows 7, 64-bit and an ageing Yamaha Clavinova CLP 500) but I’ve made progress for the time being by setting the tempo of the piece (to be played on the F4 command) very slow indeed (quarter notes, – crotchets – at 40/min), with note and rest resolution both set at 8th, and with a percussive staff (woodblock) ticking out semi-quavers (16th notes, so 160/min) like a metronome, as a guide. This works for inputting a musical line containing nothing quicker than a quaver. Crotchets at 50/min also works but the accuracy of the result begins to fail at 60/min. It suits me because my piano-keyboard skills are not good and I, as well as the technology, fail at higher speeds!
