Hi Grandorgue/Hauptwerk users,
I have recently completed a Grandorgue practice console using a home-build 30-note pedalboard, 2 stacked midi synths for the manuals, and a touch screen for registration. I must say that I am VERY impressed with Grandorgue and I heartily thank and congratulate all of it's developers!
In the absence of a human page-turner, I needed a way to scroll PDF sheet music files (displayed on a second non-touch screen).
I know that there are commercial foot-switch-based solutions for this, but they are not cheap and using a separate foot switch seems impractical for organ use. I also wanted to avoid any additional cabling if possible.
My solution was to develop a small Windows application that sends scroll up or down commands to Acrobat Reader from any two (programmable) midi note-on sources on any channel. Eventually the required midi signals may come from a pair of spare toe pistons, but for now I am using C#0 and D#0 keys on my 'great' manual as this manual has 73 notes and the bottom octave is otherwise unused. This strategy introduces brief interruptions into practice sessions involving the left hand, but this is far quicker than scrambling for the PC mouse or keyboard.
I have included a copy of this application as an attachment free for anyone who can make use of it. Comments welcome.
The default configuration sends page up or page down keystrokes to Acrobat, but there is an option to send a preset number of up-arrow or down-arrow keystrokes instead - to cater for various page zoom settings.
Regards,
