So im going to get a real midi keyboard soon but however right now I use just an on screen virtual keyboard that makes it so I use my laptop keys as a keyboard. Right now I dont know how to get it to work with reaper and GPO 4 aria player. If I just boot up the aria player I can go to preferences and choose the virtual midi keyboard as a midi device but when I have it running through reaper I cant seem to find that option. I got some great help earlier on this forum and basically I just want to know how to get the vmpk working and for when I do get a real midi keyboard if someone could give me some steps on how to get it set up and working properly with reaper and the aria player. Im using a mac btw. This forums been great, thanks again.
