Have you ever wondered what note you're playing at the 1st fret on the 6th string with the B pedal pressed? With this question in mind, I created a note finder in Java to identify and play [in MIDI] any note at any fret with any combination of pedals. The application is based on my MSA Classic which is tuned to E9 and has three pedals and four knee-knockers.
I hope that you find the application useful. If you have any feedback, please shoot me any email.
Currently, it only plays single notes, maybe I'll tackle chords on the next iteration.
Let's say, for example, that you want to play the note on the 5th string with the bar positioned at the 1st fret with the A and B pedals pressed. You would just move the slider to the 1st fret, select the A and B pedal buttons and click anywhere on the 5th string. Hopefully, this will produce the corresponding MIDI note. The note finder is a web application [Java Applet], so if you have Java installed on your computer, the applet should simply start up when you navigate to the link.
