Simply putting a VSTi together to handle the Capitol sounds from any modern arranger would be tough enough. Now do one that also does ALL the Variations, the DNC/SA articulations, the Guitar Modes and voicings, from THREE different arrangers (who's going to do all this to just play styles from ONE arranger? - it would be far simpler to buy the arranger in the first place).

Most modern arrangers have well over a thousand sounds, including all the Variations, which can be radically different from the Capitol sound. One acoustic piano, one Rhodes, one clavinet, this just ain't going to cut it nowadays. The modern arranger styles go WAY deep into the available sounds, to get styles that are well balanced and fresh. We have moved SO far away from the simplicity of General MIDI that the task of creating a soundset to successfully emulate (let alone better) a modern TOTL arranger has gone beyond our mere mortal abilities!

Sure, if you just concentrate on the basics... you can get it to work. But 40-50+ kits ALONE? Who's got the time and patience for that?
