Hi Gambler,
Very nice setup for those who play organ.

Personally I don’t, I just have my p121 piano with sx stacked above, but I still like to have them close as possible so that I can reach sx buttons if I need to.

for those looking for a duo keyboard controller that can be what ever you want it to be . i considered this but then im getting back into more programming less real playing with this. being an organist this would work for me. but for a few hundred more i could get the real thing. then i have to deal with an arranger. sometimes i wonder if i should stay just a single keyboard and quit over thinking my options and just play, afterall im not playing on stage anymore.

Paying a little extra now you could have this https://www.musicstore.com/en_US/USD/WERSI-OAX1-Deluxe-Set/art-KEY005 (Add a pedalboard if you wish) which as it is software based will be continuously updated over time (The previous OAS system lasted 14 years) so no need to swap keyboards every few years.
It also has the added advantage of an integrated VST Host which will allow you to use sounds beyond any arranger as if they were an integrated part of the organ. (No faffing about with Midi or modules)
Over time price wise you will find it will work out cheaper than a TRX type system where the arranger is constantly changed for new features every few years. (Oh and did I say there would be no faffing around)
Buying cheap can bring long term pain; spending a bit more will give you greater long term satisfaction. https://www.youtube.com/channel/UCQ_QO0l4rV9zfPacRKCIAJw/playlists
Whatever you choose, always have fun and never look back.

There are several reasons why i still dont have this setup..
-no midi multipads, only audio one shots..
-no freely assinable sliders..
-akward vst interface, and no support for vst effects
-price ( but thats the least of my worries)

However the full support for yamaha and Roland styles makes me very happy
When the lockdown is over, i will definately ride down to music store and give this another try. No pedals.. just 2 keyboards..

Yes, multipads are a bit of a pain, however OAS had the option to use them as full multipads, so it will probably just a matter of time before they are included in an OAX update.
I believe assignable sliders were added in the last update. (Or possibly even the previous update)
VST Effect Plug-ins is fully supported in the Host, but currently all editing has to be done from within the VST Host. Providing you just select the VST user page in the Host it is pretty easy to use and pretty much the same as other VST Hosts.
As I said in my post long term it should work out cheaper.
I am led to believe that Korg & Ketron converters are on the way. (Don’t forget OAX (And OAS if you have the OAA installed) has native support for T2 styles without needing any conversion)

One thing that would be nice would be integration of Cubase Elements (Or other DAW) so you could really have fun editing styles midi & audio files.

AMEN!! But I would make sure that one of the keyboards (bottom?) was a 76er and suitable for piano-style playing.
