Question

I can see the signal is going through but there is a definite delay between the time I press the piano key and when I hear it coming out of my speakers.

Answer 1

Hi,

Decrease the buffer size on your audio device to decrease latency.  This is typically done on the audio device control panel and in many cases can be done from inside of Studio One.
