    1. It is strange, Synthtopia do seem to like to promote him. That Muff thread is the least of it, would definitely recommend people do their research – buyer beware

  1. Its a shame that he didnt open an option for changing the sounds…example so you could insert your own sound eproms from a real Oberheim DMX (Or Linndrum pr SCI Drumtrak) due to that their sound roms were compatible with each other because they were using the same DAC 🙂

  2. It totally looks like some sort of a scam. Where are the demos? Who would ever buy a new module without even checking it out or at least hearing / seeing a demo online?
