It was very hard for me to pick what number to rate this as. For what it was intended to do, ten out of ten; it's a classic sound and very versatile for what it is. But overall, it is somewhat limited, so I guess an 8. It is tweakable in a good amount of ways, but it is set in one basic idea that doesn't allow too much room for change, but this is after all an emulator of an old analog, not intended to be a replacement for Massive or anything like that. I've already used it in a track of mine, it's very handy for somewhat softer sounds that echo and move but also carry a bit of melodic value. The only issue with its built-in effects, though, is you must be careful with how you sequence/compose with it, as the delay can stack and become a bit of a mess. I'm sure most would already be aware of such risks in delay effects, but the delay on this synth is quite impressive. With some panning modulation and a little reverb, this synth becomes something very special indeed, and I love it. I know I'll be using it more than just this once. But if you're looking for something rougher, harsher, faster, etc. etiher prepare to process this synth heavily or just accept that it is a bit limited. Though that certainly isn't to say it's bad; not at all, because it does what it was meant to very well and for free. Here's where I used it:
You can hear the first little riff of it at 7 seconds in, and it can be heard another couple of times in this preview. The effects I used weren't much, just auto panning, stereo expansion, and maybe a reverb or delay plugin, I can't remember at the moment. I would definitely recommend at least giving this a try, even if you weren't necessarily looking for something like it. You've got nothing to lose, you could find a way to alter it, and you may want a synth like this at some point so why not? Easier than making a similar sounding patch in Massive or something else like that.
