I have huge class sizes and limited keyboards, however, I do have a few PC's with USB keyboards. Is there a way I can use these just as keyboards. I have Sibelius but do not know how to just play the keyboard without it recording. I have tried to Kontak player on Sibelius but cannot get it working.m Basically, I just want to save spending more money for more keyboards when I dont even have the space or the budget. Thanks in advance. Oh It will need to be an idiots guide!!
