It's rock-solid stable, it's wonderfully intuitive and the sonic quality of the synths, sampler & effects is killer!
The best part for me, is the low price(which frees up your cash to be spent on the specific 3rd party VST's you really want....rather than spending a big wad on native mid-grade and suite-grade bundle packs that most DAW's offer.)
even though Ableton & FL Studio have their strengths(such as some interesting sounds/modules/..etc.,.)..both of these DAW's are cluttered & confusing & any DAW that inhibits workflow in this manner, I avoid at all costs.
I'm still very new to MuLab....so perhaps down the line...I may have a few minor gripes or feature requests...but on the whole, there is no other DAW in existence, with a better workflow(even more so than my Reason DAW and I've been a user of it since 2007.)
I only wish that there were additional presets/sound sample libraries for purchase because I am in love with MuLab's synth & effects.
By the way....I couldn't find any info on MuLab's synth, in terms of synthesis method(additive, subtractive, FM..etc.,.?)
Mulab will probably never be my primary DAW(per se)...due to my Reason 10 having the obvious built-in synths and RE's, so I will be ping-ponging back & forth between the 2...but I did abandon my Mixcraft 9, Studio One & Cakewalk Bandlab DAW's.
All this being said, I am puzzled as to why Mulab has remained under the radar...whereas Ableton & FL Studio get all of the notoriety & praise. Then again...perhaps MuLab being low-key & small, is for the very best(so it doesn't become riddled with an excess of features & thereby being perverted into bloatware.
