Greetings from a new member!
I just completed a conversion, XB2 to HX3, and would like to say the sound is outstanding. As it happens I also own a 1959 C3 (with 2 x Leslie 147), and there's no question Keyboard Partner have nailed the authentic Hammond sound with this circuitry.
There does seem to be one minor problem with my new setup, though. When I connect a MIDI source for pedals, the pedal drawbars have no effect on the sound. That is to say: the pedals do sound, and the signal is output appropriately on the R/Pedal jack when my Leslie 330 is plugged in. Also, when I hold the Organ Solo button for 1 second to edit the pedal drawbars, the display does update to show that the pedal drawbars are now active; and working the first four drawbars does change the numeral display for the three pedal drawbars plus Sustain. But, the problem is that none of this changes the actual pedal registration -- i.e. there is no change to the pedal sound itself.
So for example, if I'm playing the pedals and activate the pedal drawbars, then push all three of the lower drawbars all the way in to zero, this should silence the pedal output. But instead, it has no effect at all on the pedal sound; the sound just continues with whatever the earlier drawbar setting was.
Do I have something set up incorrectly, or is this possibly a bug in the firmware, or the like?
