The V-synth is still new so I can't say anything about that . The Triton , Trinity , Z-1 all have the same sound library . The only difference is the Triton samples . The Roland XV , JV , XP , and Fantom have the same sound libraries .
Yamaha S series and W series and the CS1X and CS2X have the same sound libraries .
This is why I don't bother with any of these machines , they are sample playback machines rehashing the same samples over and over again . They change the effects , add an arpeggiator and call it something else .
Since they are sample playback , there isn't really much else they can do .
The VA gear and analog gear offer a chance to make music rather than read manuals and scratch you're head wondering how to get 128 note polyphony out of the thing .
I remember when the Poly-61 came out , and then the POLY 800 . No one ever imagined a polyphonic programmable synthesizer could be so inexpensive .
The Prophet 5 was an innovative machine , the PolyMoog was not . The PolyMoog was an organ , not a synthesizer . The PolyMoog , Arp Omni , Arp Solina 4 , Crumar Orchestrator , Roland RS-202 , and Korg Poly Ensemble S are essentially organs .
They Use top octave divide down circuitry found in combo organs .
The PolyMoog had one good preset , the VOX HUMANA . The string sound on the ARP OMNI was far better than the PolyMoog . I would have to say the Freeman String Symphonizer , ARP SOLINA 4 , and Korg Lamda ES-50 are my favorite string machines .
