Vintage B3 Organ is a Hammond B3 emulation plugin, which ships with MainStage 3 and Logic Pro X. It’s a great sounding virtual instrument, and emulates many Hammond B3 physical traits as well — such as the lack of a sustain pedal. In this tutorial, you’ll learn how to enable sustain in the Virtual B3 Organ plugin.
By default, the sustain pedal is mapped to control the Leslie’s rotor speed. Once that mapping is undone, the sustain pedal reverts back to operating like a normal sustain pedal.
First, go to the ROTOR CABINET tab in Vintage B3 Organ’s GUI. As you can see in the screenshot below, “SusPdl Temp” is mapped to SPEED MIDI CONTROL.
