Sotharmnans MiiniProphet Pro One cone with extras in Eurorack Modules v 2 LJ er fYlarnusal Thank you very much for purchasing consider to purchase my MiniProphet eurorack modules Please read this manual before setting up your MiniProphet to avoid malfunction caused by wrong handling Foreword I once had a Sequential Pro One that I was very happy with It is a very great sounding and versatile synth Problem with it was that it was very unstable and I felt like I spended more time repairing it than playing on it and I certainly did not dared to use it live but I did wanted to Therefore I designed the first MiniProphet desktop A small easy portable package that was very easy to bring for live shows and since all parts except for the special CEM chips were completely new it was much more stable than the original one A MIDI to CV interface were built in for easy connection to a keyboard and an extra filter were added for more sonic experimentation A while after I had sold all che 3 MiniProphet desktops that were built and I started to make a new one for myself I got the idea to try to make it in eurorack format to get this great sound with even more flexibility MiniProphet EuroRack was born Gotharman July 2014 Included in the MiniProphet Eurorack set double BAN module Aa ea ur SRG ES ER oe aT 12 a Ae ad s e Portamento deTune sxt CU _ PumanN elo Rade Kybg un EM Puma C
