Hey all - back in 2011 I created a commercial soundset for the MNM using all of my insights from exploring the heck out of the DigiPro machines. At long last I put the finishing touches on it. Please feel free to see if it is worthy for your consideration at http://www.gum.co/fireknife.
There is also some free SYSEX demo files for your Mono, a (long for a soundset) manual, and links to all of the audio demos at http://www.musicbycatabolic.com/fireknife/
If nothing else, enjoy the freebies and have fun listening to the audio possibilities of the one-of-a-kind Elektron Monomachine.
