I’m currently waiting with great excitement for @FantomXR to finish my custom keyboard (see here), which I am convinced will absolutely ROCK for Hammond duties - I’ll report here once I have it.
In the meantime, I’m reasonably happy using my Yamaha Motif XF and XS - pretty decent keybed, especially compared to my previous choice (Alesis VI-49 - great selection of controls, but not a very nice keybed).
Cheers,
Torsten
