Actual User Reviews
I've just been playing with Catalyst 2 for the last 3 hours. It's fantastic, my congratulations - I particularly like Tango Nuevo, it's great to get a combi in 6/8! --Tim
There is something about a KARMA combi that's like a little piece of magic. The KARMA combis in general inspire like crazy...ahead of their time, and KARMA is superior to auto arrangers, and arpegiators. Imagine if your KRONOS was filled with them! --spaceman3
Thanks for creating another great set of combinations! ...these are really amazing, right out of the box. I just discovered that each combi has 8 different scenes, each of which is interesting in its own right. What amazes me most is how incredible KARMA is. It's like there are actual musicians trapped in there somehow. --rkarlberg
Just spent the last 2 hours playing this set. Wow is all I can say! They are all excellent, making the full use of Karma and existing programs within Kronos. They are extremely intricate and the possibilities seem endless for improvising. I have always liked your sound sets, but these have to be by far the best IMO. My favorites so far are Sublime Dreams, Requiem for a Robot, and Afternoon at the Rex. --mikeyd
You can hear all the hard work that went into these combis. I look forward to be inspired and many new compositions. Thank you, Stephen and Jim! --TotallyKenny
Jim and Stephen, I just wanted to pass along my thanks for making these new combis available to us. They are a joy to play and will open up numerous avenues for new song ideas. I know it takes a long time to generate the combis as well as the controllers and effects. Not to mention the explanatory dialogue. From my perspective it is greatly appreciated. Thank you. --nitecrawler
