i got one and allthough i never soldered even a cableimade a successful build. thanks to an excellent step by step building guide and a very helpful community the project was a lot of fun. The synth engine has quite a unique sound and is perfectly fitted for modern electronic music styles. Another big plus is that the firmware develops and now you have even basic sample import and a triger out board is available for the modular heads. What i like most of the LXR is the UI and that you can use it as a midi step sequencer. And yes, it has a bitcrusher per instrument + a great "beat repeat" feature plus shuffle/swing.
