Hi Ludo
My console has switches, but that is not how I operate Music Reader.
You can obtain a number of switches from Music Reader to operate the software.
I have just looked at their web page and there are many more options for the operation than the last time I visited (
http://www.musicreader.net/)
I have found the best one for me is a tongue operated switch working via Bluetooth.
Being a rather unskilled player I found trying to operate a foot switch at the same time as playing the pedals got me into all sorts of contortions (and bad notes).
Do have a look at their website - as I said I have been using Music Reader for quite a few years and it is, in my opinion, perfect for the job.
