I have a Roland VK-8, it has a bank of physical drawbars, as well as all the usual rogan knobs and buttons (Vib-Chorus, Leslie On/Off).
All of these things broadcast SysEx messages. In Logic Pro X Vintage B3, under the "expert" page, there is an option to receive these messages via a preset for VK, as well as other popular 'clonewheel' keyboards (Hammond CX, Nord, Crumar, etc..)
However, when I select VK nothing happens to the controls when I make adjustments on the Keyboard.
Any help, or a push in the right direction would be much appreciated. I can provide pics or data from midi capture or Logic, just let me know.
Thanks
EDIT: here is the page on apple support that discusses using a "Hardware Controller" for the Vintage B3 https://support.apple.com/en-bw/guide/logicpro/lgsia12cd8e/10.7.5/mac/12.3
