    Smile Scrolling PDF sheet music

    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,

    Thank you for this tool.

    I keep using "traditional" " paper" scores but it can be usefulll...
    I won't print all the free organ scores on this site :
    http://imslp.org/wiki/Accueil
    too much paper, too much ink ...

    (on paper score, you can write your comments, fingering it ... )

    I've got to install my 16/9 screen in a "portrait" position, in a 9/16 way !

    Smile PDF scroller version 2

    Hi Panos and Sesquialtera,

    Thank you for your feedback re my PDF scroller tool.

    In response to Sesquialtera's comments about the need to be able to annotate a score and define fingering, I fully agree that there is no real substitute for a printed copy in some cases.

    But this feedback reminded me that the free version of Acrobat reader does not cater for adding comments to PDFs. So I have added support in version 2 (attached) for the free version of Foxit reader - which does allow for comments to be added and saved. This is certainly not as convenient as a pencil and a printed score when working at the organ console, but it may be useful in some cases.

    I have also fixed a bug in this version that could cause doubling-up of scroll signals for midi sources that send note-off events as note-on with zero velocity.

    Regards,

    Diode --|>|--

    Hi Diode, Sesquialtera

    I print from pdf the scores I want to practice hard, also as you say, editing with pencil fingering stop combinations ect.

    But for some other works (indeed too much ink and paper needed..... it is better to buy the book) I paractice on my small 49note USB keyboard with my lap just behind it and above, loading the score in Adobe.
    My main problem , besides page scrollong, is the current page itself, as in my 16:9 screen I can read till the half of it... he he

    Anyway, Diode I just got your v2, v1 worked fine, I'll see and post back
    THANKS !

    Hi Diode . . I really like the idea and simplicity of MusicScroller but was wondering whether it would be easy to add a third command section to it.
    I want to run song lyrics triggered from a MIDI file but the running order will alter from show to show. So my suggestion/request for the third section: If MIDI notes could be allocated to a page number then the first NOTE ON in the MIDI file would 'jump' the display to the song that begins on that page . . the other two existing commands could then be used to scroll the pages from there. This section could be optionally activated.
    I hope that makes sense . . I'm sure it would be a useful addition for many users.
    Cheers . . . Martin
