Hi I'm trying to use a Yamaha sy99 keyboard with Reason, but Reason won't read the keyboard. I installed the usb adapter and I installed the keyboard in Reason as an external keyboard because Reason doesn't have Yamaha brand as a choice.

Please help!!! Is urgent!! I would like to make some good beats and this program is really useful for that matter!!!

When you say external, you mean "other" right? Make sure that your drivers are installed. On a pc, you can check this in the device manager. Did you hit the "find" button?
