Since I have a long standing fetish for string machines and have become a bit of a trainspotter I thought this could be a fun thread.
For your delectation, some of my favourite string machines and recordings with them...
Roland VP-330 (RS-505 has the same string section, so lush, nothing else sounds quite like it)
Yamaha SS-30 (you can vary the amount of the ensemble effect with a knob, very handy to make it blend in better in the mix. SS-30 comes in at around 1 minute)
Korg PE-2000 (has a gorgeous built-in phaser used in this recording)
Logan String Orchestra through an EHX Small Stone (Compared with the String Melody 2, the String Orchestra has two more sliders with "orchestra" sounds, a buzzy kind of brassy sound, used lightly in the intro)
