I've both, if I had to choose it'd be the AN1X over an AN200 or even two AN200s. I see little purpose in having two AN200s, maybe a pair of AN plg cards in an EX5, Motif, CS6x or whatever else would fit two boards, but not two AN200s. If you made one of them a DX200 then perhaps that would be something to think about, anyhow I'm not sure it is strictly the sound editing capabilities from the front panel, but yeah well ok that would be a big part of it. The AN200's small footprint as a desktop module is really nice, but it does come at a loss of being able to easily access all the AN engine's parms and capabilities that you can more quickly get to on the AN1X. You wouldn't think so because it has more knobs, but the way it is done certain things are more imediate and other things arn't, they feel like editing two completely different synths, yet they have the same crisp AN sound. A lot of the important features and parms are still up front, perhaps even more immediate for some more favorable things, and you can still dig in quite a bit on the AN200, but its sequencer isn't really all that different from the AN1X's programmable arp/sequencer. However, you can have a few extra drum parts/tracks and mutings etc., on the sequencer side so it is defiantly more valuable as a sequencer than the AN1X. The AN200 is simply a nice sounding little piece of groove kit. The expressiveness and nuance of the AN1X as a performance synth is something you won't let go of a second time after you realize it.
