The perfect poly. I've owned close to 50 synthesizers in my life, including some vintage analog warmth such as the Korg Polysix, Roland Juno-60, and AKAI AX-80. The AN1x trumps all these for me, not because it sounds "warmer" or "more analog"- it obviously doesn't. It's a 100 per cent digital machine. I like it because it makes me sound different from everybody else currently occupied by the vintage analog craze. I don't mean to say there isn't merit in vintage analog- I'm saying there are other things as well. The AN1x is as analog-sounding as you want it to be- lush, warm, unstable (if programmed to be so), but it also does glossy, crystalline digital FM sounds extraordinarily well. I had a JP-8000 for a while that sounded cool, but sounded like a bucket of hot, glitchy slop if I pushed the LFOs too hard. It didn't like doing those intense, oscillator-mangling modulations that I so crave. The AN1x, on the other hand, is perfectly happy making these types of extreme, audio-rate modulations, and sounds surprisingly musical doing them, too. Also, I like the edgy nineties look it has. Very endearing.
Its blue and it just sounds fantastic! I might add that is PLASTIC! But when I play the AN1X I fall in love with it again and again. You can spend hours on end playing this snyth. It has a huge " fat" sound to it. It really sounds great for a digital analog synth!
This is one of those secret tips in my opinion. The case and the design are pretty horrible, and it is not the easiest to use, but it sounds great if you know how to get those sounds out of it!
