Well, what can I say? I've been using Muzys since April and I really couldn't be happier. I guess the best way to do this review would be to list all of the pros and cons I can think of.

Pros:
-easy to get a grasp on
-excellent work flow; very fast to work with
-very deep and well thought out
-integrated modular synth/sampler (muzynth) with multiple routing and modulation possibilities.
-the muzynth has the best sounding oscillators I have heard from any softsynth (IMO of course)
-support for wav, aiff, and sf2 samples
-integrated audio editor for slicing, timestretching, reversing, and several other dsp functions
-top notch vst(i) support
-rock solid stable
-all parameters are fully automatable
-excellent customer support
-excellent effects included
-superb sound quality
-on top of it all, very low price (which is no indication of how awesome this piece of software actually is)

cons:
-no disk streaming, yet (all samples that are loaded are stored in ram instead of being loaded from the hd, amount of samples loaded are limited by the amount of ram), but it is at the top of Jo's to do list.

As far as the pros go, that's only off the top of my head and I know there are a lot more. I would urge anyone looking for a host to check out Muzys. It definitely doesn't get the recognition it deserves, but I'm sure people will eventually realize. :)

Do yourself a favour and check out the demo. You'll be happy you did!

When I got into sequencing late in 2001 Muzys was still a cute little baby in terms of features, no VSTi-support, no real internal sound generators. 16 basic channels, no aux sends or even master outputs.
Did I care? Did I bugger. I was new to the game, not knowing what VSTis were myself. This peculiar situation certainly explains a lot of my love for this program. Unlike a newbie being exposed to a gazillion options, I had a chance to learn and grow along with my favourite piece of software.
And look at where Muzys is now. With Muzynth it boasts an extraordinary internal sound generatior, covering pretty much everything from analogue burps, to FM-synthesis to serious multisampling, has replaced a lot of my synth gear and shortened my wishlist for new VSTis considerably.
What's different in Muzys? Well, the GUI, for starters. Instead of cluttering your screen with 37 windows you get one (!) application window with three major areas: The structure panel (where loops and songs take shape), the transport bar and a multi-purpose area that serves as the stage for Muzynth, mix desk, sample editing and VSTis alike.A bit of clicking is required, especially to get down to the mixing channels, but I'd rather have that than a sscreen full of rezisable windows. Horses for courses I reckon.

The loop editor, you gotta love it. Instead of having to start a new song in the vast expanse of blank space aka linear sequencing (horror vacuui anyone?), you can chose to play back all your midi and audio data in the loop editor first, where you can play around, developing your ideas, all from within the safe womb (that's how I see it anyway) of ever repeating patterns.Don't hesitate to doodle with the loop composer and your keyboard in realtime, Muzys's incredible stability takes care of that. I've performed genuine "DJ-sets" with it, going from one song idea to another, playing happily for hours on end. Heaven. If you think the idea is ripe to be a song, just copy it all over to the song composer.
I haven't mentioned the playroom yet, that's because I haven't tried it out so much yet.
Slap me.
But from what I experienced, it is an even more powerfull live tool than the loop editor, allowing you to change between 128 loop compostions via..tadaa..program change, have it all recorded
- thus creating a new song(or at the very least its backbone) in no time at all. Come to think of it I really should try it out.
No disk streaming yet, so if three minute mixdowns or serious guitar recording are what you're after, I suggest you look at a dedicated audio recorder for that. Having said that, nothing is likely to replace Muzys as my sequencer. I'd rather use two programs for squencing and bouncing than not having Muzys.
And that disk streaming thing is being worked on, so: No worries, I say.
Customer support is great. I get the impression of a big family rather than a customer/manufacturer relationship.

And yeah, did I mention that this thing rocks???
