I was getting frustrated with the B-3 Tone wheel organ in Analog Lab. My issues: (1) the Leslie speaker does not react to the modulation wheel and (2) though you can control the drawbars for the upper manual via midi you can’t do it for the lower manual.
For most people the latter issues is not relevant as there are key switches from C-1 to Bb-1 which gives you access to the presets of the lower manual Tone wheel voicing. So you can just choose your voicing upfront while your keyboard is set to very low octaves and switch to higher octaves to play your song. Also if you program your DAW there is no problem as you can access the key switch notes in your piano roll without a problem.
But if you are an organ player and you just want to play in Analog Lab like you would on your organ that is highly annoying. Changing the voicing is part of playing. If you can’t it is like piano players not having their pedals.
Issue (1) is solved quickly. As you can go to “Keyb. Settings” and assign the modulation wheel to the “fast” button of the rotary effect. Works like with every other organ VST. While you are at it: If your keyboard features Aftertouch give yourself a treat and assign Aftertouch to the “brake” button. It makes it so much more fun to play if you can slow down the Leslie while playing with a fast Leslie.
Issue (2) took me a minute to figure out. But if your keyboard provides you with pads you might be able to edit how those behave. I set my pads to midi channel 2 and programmed them to play Db-1 to Bb-1. Why not program C-1 also? Because this setting is for all drawbars pushed in which results in mute and nobody needs mute while playing. It might be a good idea to set up all other pads for CC midi messages so you have more controls you can access in Analog Lab via midi learn.
I saved those midi settings to a dedicated preset in my keyboard so I can access it when I want to play Analog Lab’s Tone wheel organ.
This is quite a long post. Sorry for that. Actually, I made a video about all this. But it is in German. Sorry again!
