There is 1 Sound Project for this Locomotive
N&W Y6B 8 bit project by John McMasters, added on May 8, 2013

NOTE: CV155 MUST =1 ARTICULATED project is running "Articulated" sounds with both front and rear cylinders.


NOTE: Make sure that the model CV133 Steam Chuff/CAM config, 128=>EXT cam, 1-127=>DRIVER dia in inches[63] and CV134 Gear ratio are adjusted so that THERE ARE 4 STANDARD NON-ARTICULATED CHUFFS PER REVOLUTION. ARTICULATED SOUNDS ADD AN ADDITIONAL 4 CHUFF SOUNDS TO THE MIX.


                New Features:

                                g) on reversal clash with F15 and/or F11 is

                                                on [F15 off + F11 off = no extra sounds]

                                                                [F15 on + F11 on = all extra sounds]

                                                                [F11 controls auto clash and uncouple]

                                                                [F15 controls auto clash]

                                h) auto rod clank cyl blow down (steam cocks open)

                                                will coast after deceleration for up to 5 cycles playing ALT_RC

                                i) coal grate

                                j) coal chute

                                k) auto brake on decelerate (two rates hard and short)

                                                F9 Leave off to disable auto brakes

                                l) optional cylinder 2 sounds varied; Set Slip mode=1 OR F26 ON (Articulated Cylinder 2 Chuffs)
