Here's a way you could do it :
1-)Open up the ES-2... start with the "Vintage mix" preset.
2-)Change the 3rd oscillator to "Noise".
3-)On ENV 3, change the attack to 0ms / 1.60ms; Decay to 89ms;Sustain 0.055;-Time rise to -900;Release 15ms.
4-) Change the frequency of Osc 1 to 0s -18 c and Osc 2 to 0s 18c to create a slight modulation effect.
5-)Turn up the Analog button.
6-)Turn up the Intensity Control to taste to create a Chorus effect and turn down the tone midway.
7-)Insert the Bitcrusher (Resolution 9 bits, downsampling 1x)
9-)Insert a Space Designer with the "Deep Space" preset. Turn up the wet Rev slider.
10-)Use an EQ to create a Hi cut and slight boost at 300 hz.
You could also add a very subtle tape delay with flutter and hi cut.
Hit a key around g#5...
Hope it helps... Of course you could also use a good sample with the EXS24!!!
