I have felt for some time that it'd be neat if there were a FREE easy to use step sequencer program that lets you use any .wav files for sounds, but also offers powerful editing and synthesis toolsets for each sound, with the ability to shape and sculpt sounds extensively and dynamically while the sequence is playing (but at the same time not compromising the ease of use of the sequencer).

Enter FlexibeatzII. A self-contained, standalone ten channel pattern-based music-making machine with a gentle learning curve, yet one with considerable depth that can play along with your DAWs and midi gear, if you want.
