Sonus 40 Midi Control (1 reply and 1 comment)
Your experience description leaves a lot to the imagination, however I assume you are taking the organ's midi output - modifying it - and then feeding the result back to a midi input. Apart from useful outcomes, this has a possible bad effect of creating a positive feedback loop.
However AutoPedal should not have this problem as the real pedals are not being used. My program eplayOrgan (free from my website) implements AutoPedal and it should be possible to use it to create AutoPedal for any organ.
Feed your organ's output to eplayOrgans's input and feed its output back to your organ's input and turn on Autobass. I have not tried this but with knowledge, creativity and care it could work. Oher possibilities such as those you discuss above may also be possible by this method.

Thanks for your comments which are helpful. I didn't go into much detail in the post for brevity's sake but yes you are exactly right, that's what I am doing. Possibly a feedback loop might be what my Sonus is trying to avoid in refusing to fire off a midi message for a key which it sees as already pressed, whether the 'press' is real or virtual (via incoming midi message). That would make sense as it is a much more advanced midi implementation compared to the basic Princeton organ. So I'm opting for 'Sonus knows best' and will avoid loop backs to the same channel.
Your website software is probably overkill for my already-solved AutoBass requirement, which is really just intended for a pianist to be able to play a few hymns should that be necessary. However it does look interesting from the organist's point of view so I will delve deeper.
Once again, many thanks

Home: Sonus 40. Church: Princeton (Possibly manuf by Viscount c.1990s)
Church already had pipe organ, recently acquired the Princeton from sister chapel that closed. Thought it could be useful in absence of organist, but unfortunately no AutoPedal. Decided to try and implement AutoPedal in midi via laptop. Easier said than done but eventually managed to pick out just the lowest played notes on the Gt with help of Bome Midi Translator. Organ's midi very basic, only keyboard is implemented. After this success, tried other things with same equipment, such faking "Swell Super Octave" and faking mutation stops which don't physically exist on the organ. Discovered that much was possible via a translator program and simple midi loop back in this way.
Not able to resist the urge to tinker, I wondered does any of this also work on home Sonus? Sometimes! Stumped at faking a Swell Super Octave in this way, while faking a Swell Super Octave to Great coupler works exactly as expected.
Example - using the faked Sw Super Octave I play C4 on the swell. As required it also activates C5 via the software. But if, while holding on to C4, I play C5 (which should also turn on C6), nothing happens because no additional midi message is sent from the keyboard. It seems that, unlike the Princeton, you can't loop messages back to the same channel without losing all the unison notes in this way. But you can do it from another manual (or an external keyboard). There probably isn't a solution and in the end it doesn't matter. However, thought I would post this experience just for community information and in case someone knows if I am missing something obvious.
