Welcome to the OASYS CX-3 Expansion Instrument!
The CX-3 EXi modeling engine in OASYS faithfully reproduces a tonewheel organ and an accurate emulation of its rotary speaker amp, allowing nuanced control over such parameters as tonewheel leakage, key click, tube emulation, adjustable overtones, with proper foldback characteristics. The CX-3 Expansion Instrument in OASYS improves upon the original CX-3 with improvements in the Rotary Speaker algorithm, assignability of percussion to either ‘manual’ in a split, and new chromatic pitch choices for the EX drawbars and percussion. This Tour Guide is your first stop on an amazing journey of discovery. Our goal here is to get you comfortable working with this model, so that you can fully take ownership and give this amazing organ emulation your personal stamp.
After you’ve finished this tour, you can learn more about this great instrument by working with the OASYS Operation and Parameter Guides. And you’ll find new OASYS tutorials, tips and tricks, support materials, and discussions with other OASYS owners by visiting www.korg.com/oasys, www.karma-labs.com/oasys and www.korgforums.com/forum/phpBB2 on a regular basis!
Where to find the CX-3 Programs…
Select Program Bank User-F
The CX-3 Programs occupy the lower numbers of Bank U-F, U-F-000 through U-F-051. The higher numbers contain more great AL-1 Programs. Why not more? Much of the variety and magic of playing a tonewheel organ comes from moving the drawbars yourself, and operating the controls in realtime – it’s not about changing presets as much as it is playing with the instrument in an interactive fashion! Plus, it’s so easy to edit the drawbars and tone to your liking, that you’ll be creating your own original CX-3 Programs in no time!
Tutorial: Select Program Bank User-F-000, Felix’s Da Kat
This great program emulates an “all-stops-out” organ: think “Good Lovin” by the Rascals from the 60’s.
Note that the factory organ programs all ‘wake up’ with the CONTROL ASSIGN mode defaulting to MOD: TONE ADJUST. Faders 1-8 are your first eight drawbars, and the MASTER fader behaves as drawbar #9. Move the faders as you play, noting that the display’s drawbars update to the changes you make. Touch the small drawbar area beneath Upper and an enlarged view appears, which also updates and responds to your fader movements.
Push the joystick away from you (+Y), and the Rotary Speaker slows down; push it again and it accelerates. Try this while holding a low note and a high note together and you can hear the accuracy of the CX-3 rotary model: there are separate acceleration/deceleration rates for the horn (the highs) and the rotor (the revolving drum for the lows).
