I just noticed that in the settings section there is something called:
'Organ Keyboard Trig Point"
trig =trigger
In my default set up, this was set to LOW
In a real Hammond (and clones like the KeyB) the note triggers before the key is fully depressed, about a third of the way down the travel.
This is all part of the sound and effects palm slides amongst other things. If you set this to high the Nord mimics this whilst in organ mode - just what you need for Hammond.
Not sure about the Vox or Farfisa never owned one.
thought you guys might might like to c heck this out...
