What you are experiencing is "latency," the delay of a signal reaching the computer. It can have multiple causes. Were I playing, it could be that I am just playing behind the beat enough to throw the quantization off by half a beat. But some equipment (more likely the computer's audio chain--MIDI-converter, sound card, buffer, etc.) causes a delay in the MIDI signal reaching the recording program. This latter is what resetting the buffer attempts to address.

One suggestion, if you are using MIDI Thru to monitor your playing, is to turn it off while you record.

If your recorded part is consistently behind the beat by an eighth note, you could let it go and afterwards drag the notes onto the correct beat.

Many of us ultimately find Hyperscribe more painstaking that entering the notes via step entry.

If you have a DAW that does a better job accepting your real-time keyboard entry, you might use that and then quantize it there and import it into Finale.

Admittedly these are work-arounds.

Buffer size is the usual culprit. You want it as low as possible while still allowing everything to still function. Often there's a tradeoff but, with newer systems, it's not the issue that it used to be.

Otherwise, what J Adrian says.

Thanks for the help with this issue.  I am able to play notes from midi keyboard directly into a program called "Score Cloud" without the latency problem, and then transfer into Finale, but would like to play directly into Finale score.  Do you know how to lower buffer size?
