arguably the best sounding simulation of a vintage synth I have ever heard, the tweakability under the hood is great for dialing in the pro1 sounds you love from Yazoo and Cybotron and shit on a psychotically detailed level. The sequencer is cute and the additional effects actually sound pretty decent and can be useful in some situations. I think what makes this guy so accurate though isn't just the filter models its the snappy envelopes that capture the whole aggressive sequential circuits vibe. I use this all the time over hardware analog synths. I like it that much. So different from a Moog or Arp.
