Tassman 4 and Sonar X1 any thoughts?

Tassman 4 works without any problem under X1 (and X1-expanded). I think the synth is worth the price asked, but that's a personal opinion. Although there are a lot of presets, the real fun starts when you combine the modules and start making your own sounds. A while ago (well - in fact more than a year ago) this synth was offered in the Cakewalk store at around the same price. I never regretted buying it.

My further thoughts about Tassman... I'm not familiar with this "instrument" at all, but after browsing through a considerable manual, and listening to some of the sample tunes, it appears to be one awesome piece of kit. Perhaps just a bit too awesome for my liking in fact. True enough, I could just go with the presets and tweak as required, just to make the preset my own.

However, while browsing through the rest of their website, I think there are some amazing instruments to had... I already have two, Strum Electric and Strum Acoustic, and I'm only just scratching the surface of those. So far I am really impressed with what the Strum instruments can produce. And all with "Physical Modelling," which is pretty new to me... at least I think so.

The A|A|S Ultra Analog VA-1 synth looks and sounds great too. I also watched the video that demonstrates Chromophone... Dare I say... Amazing! Truly... I am beginning to wish that I had held off from buying the Strum bundle and got the complete Modelling Collection bundle for $499.
