I purchased studio one about a year and a half ago and started recording. I've plugged in a casio to the midi ports on the back and had no trouble at all. But i jus got a mastery 25 from Acorn instruments and its has a USB straight into the computer. I went into studio one and set up a new external device and it can see that there is masterkey 25. but when i try to record its not picking up any sound at all. Ive checked my computer and tried different usb ports on my Mac but its not making any noise. if someone could call or email me with some help that would be amazing!!
my number is: 231-313-3409
