There will always be haters... People have different preferences... People can diss away if they want to, I know what I like and no comment on the REV2 will change that anyway.
Sure, the REV2 has it's limits, quirks and stuff that it does not do, but no synth does all, and if it did, I'd be bored with it... I like to have to work with limitations and see what I can coax out of a synth I did not think I could... It's a rewarding feeling actually, and in most cases, those sound you have worked hardest on, are also those that will sound unique and be impossible to recreate on any other synth no matter how expensive.
If I feel my synth lacks a certain character or feature or synthesis type, I'll just get one that will complement... It's a no brainer really.
Sure the Curtis chip has limitations... It lacks individual volume control of the oscillators, prefilter drive and more filter types, but all the other features of the engine, voicecount and FX engine outweighs the lack of these shortcomings... Some people find that only the VCF/VCO/VCA matters, and that the modulation do not count... I highly disagree with that... One person tried to convince me that a model D is much more versatile... That is BS really... The D will not even get close to the sounds I'm doing on the REV2... It's monophonic, has no mod matrix and the FX plus engine depth to create these types of sounds... Sure a D sounds nice... But it just sound different.
Those kinds of debates are pointless, so I simply ignore them... If the REV2 is good enough for you, it' good enough, period! 😎
