Tassman by Applied Acoustics Systems is an amazing virtual analog synthesizer. This thing is a monster! I don't think there are any other physically modeled modular synths out there like this one. It's truly unique in look and sound. How can this plugin not make the top 10 VSTi list? The interface is simple, user-friendly, and fun. It's color coded to keep things neat and clean. There are lots and lots of great presets that are easy to tweak, but it's also fast and fun to construct your own instruments. The best part about Tassman is the sound — truly amazing, responsive, and as another reviewer called it. .. "MUSICAL." I highly recommend this plugin for designers, players, and producers of any genre!
I would agree with most people on here that the sound you get from Tassman is second to none and I rate it very highly, but the major problem with it is that, up til now anyway, it is not compatible to be automated within Ableton Live.
I'm actually hoping someone gets back to me to tell me this has been addressed, I would gratefully stand corrected.
