  • ON/OFF button for tremulant Great Rieger Organ

    Hi, I'm exploring the Great Rieger Organ (very beautiful instrument and very useful also to play).I think I 'm missing something (but perhaps it is there and I didn't find it yet?), namely aon/off button for the tremulant, and in this instrument for every manual a dedicated button.When I use the tremulant (most of the time a solo melodywith tremulant on one manual and accompaniment on another manual and pedal), it gives a feeling of rest, when I turn the tremulant off on the final note.I hope that that button can be made in a future version.

  • There is an on/off button for the tremulant for each manual on the MIX page. Or were you hoping for one on the COMBINE page? I use a hardware control on my master keyboard for the tremulant so it's a moot point for me.


  • Thanks for your reply. I didn't see until now the possibility of switching off and on the tremulant.

    But I 'm hoping for buttons on the combine page. With a touch screen it is easy then to put the tremulant on or off. And there is place for such a button, so I hope it will be added.

    Since a week or two I have a digital organ, so I can play the Rieger organ (yes, VSL, you triggered me to get one in my house😊👍). I enjoy the beautiful Rieger organ.

    But again I run into the problem of the tremulant. I enjoy using the combination banks. I trigger the stepping arrows with A#5 and B5 (on my organ this is the only way to change registrations, the register buttons of the organ don't send midi signals unfortunately). 
    But I can't trigger the on/off buttons of the tremulant in this way, because they are not saved with the combination banks, they are independent from them.

    So my request:  is it possible to make the on/off button of the tremulant dependent of the combination banks (just as the manual and octave couplers). On a real organ the tremulant is treated as a stop, with a stop button. 
    So I think, this makes sense. 


  • For me a new chapter in the tremulant story.

    My problem was, that I couldn’t set the tremulant on or off easily during playing.

    My digital organ uses “normal” midi signals with the keys (MIDI signals note on and note off), the manuals and the couplers (MIDI channels), the swell pedal uses cc 7.

    But the Vienna Organ Player didn’t recognise the stop buttons and the combination buttons.

    A few days ago I discovered by using another organ app, that the stop buttons and the combination buttons of my digital organ use so called sysex signals (I didn’t know anything about them).

    I found a program “Bome’s MIDI Translator Classic” for Windows, free for personal use, that can translate the sysex signals in cc signals. I had to learn of course how the program works, but I can say now that my problem with the tremulant has been solved. I can use a tremulant switch of my organ to set the tremulant on and off. Also I can use now the combination buttons of the organ!
    It is very good possible, that there are other programs that can do the same thing.

    When somebody is interested in the procedure how to fix this, please send me a PM, then I can send you some information.
