As you know, Korg X-50 provieds sound banks also available on other Triton/etc models so this sound should be easy to recreate even on those keyboards.

What we are going to do:

we will reprogram an existing program so it will sound as we need.

START

Go to soundbank “D”, program 106, and find a sound named AMSFeedback Lead (if you don’t find it, try a category search under Synth Lead).

Open ED-BASIC page.

Voice Assign: mono –> Change to POLY

Now go to OSC1 edit page

High 236: Detuned-PWM

–> change to 034 E. Organ-Perc 2 (to achive a more percussive sound)
–> change to 038 E. Organ-M1 1 (if you want a mroe legato and uniform sound)
–> or change with other organ samples if you want a different color. there are many.

THE END

You should achive a sound similar to this one (don’t mind about the background noise, but i’ve used my laptop mic for a quick recording).

This sound can be improved with a bit of tweaking, to suit your taste.
