I'm not currently at my computer but I'm half sure a sustain pedal triggers the lesley.
No.
Normally the Sustain pedal hold notes.
The Expression pedal normally is assigned to B3s Sweel pedal by default.
And the Modwheel is normally by default assigned to B3s Leslie slow/ fast switch.
The controls that's not reserved can be reassigned. The above is the standard, unless a midi CC that can - is being changed by the user in the full application.
I can add, that i apparantly don't have this leslie speed issue. I have the full V-Collection.
On one PC i have overwriten the midi CC1 for the leslie speed. On another it's default midi CC1 (modwheel). Both seems to work in Analog Lab.
But at the time being, i'm not certain about anything in Analog Lab, because of the issues i'm experiencing.
