Simple patch to be able to harness the EMU Ultra series’ cords - all of the assignable midi external controls (midi A-L) have been assigned to the automation panel. Hopefully the Hapax will allow me to channel my Ed Rush & Optical, gonna go to town on those z-plane filters! 
Note: For this to work, you will need to assign midi controllers A-L to CCs 12-23 respectively on your EMU sampler.
