I believe this is an excellent piece of software. Although limited in many aspects, fLOW allows the user to create awesome ambient pieces in minutes. As one may hear quite often, the source material makes the difference in how you will like this software. The $20 is not that hefty for all the interesting sound that this software has produced.

Now for the wish list. For the random values that control the effects, pitch and volume of the software, I do wish there were more choices of random. Like a stepped "sample and hold" version, and for pitches, an "algorithmic pitch selector" that could be chosen by scale or something...that's pretty cool, though for $20, maybe too much. Mostly, I do not want to hear sine wave sweeps on the pitch of my material. It doesn't lend to the mechanical feel that I am looking for. I am not so concerned about the effects being swept in that manner, but...again, the option would be nice. Also, more sample streams would be killer. VST support? that would be awesome, and/or more effects.

Thank You, Karlheinz Essl, for awesome software.

Cool. But has a pop up saying the program is unregistered and will quit in 5 minutes for the whole time the program is running. Funny thing, is that it only took me 5 minutes to play with the program, say "Ahh, that's kinda cool. But not worth $20 by any stretch." and then the program quits on itself.

i dunno what the developer is thinking, but this certainly isn't filling any hole in my music editing and recording studio.
