Project called name TR21 was born in year 1998, but that story has began much earlier. All started in the middle of 80's when TR21 performed many experiments with generating sounds on 8 bit personal computers like Timex 2048 or Atari 800 XL. Next phase was an experience in domain of design engineering - simple analog synthesizers and drum machines. After that TR21 began experiments with fitting and mixing analog cassete tapes. The culmination took place in early 90's, when he started an age of sampling and processing sounds thanks to techniques like: Covox, own invented A/D converter, personal computers PC AT class or very popular in this time tracker programs. At beginning of the 90's TR21 also was a member of a death metal band as a drummer and vocalist. Project became more stabile in his workshop in 1998 and kept on up until now in a little bit more innovated way. All is based on sequencer launched at PC class computer which control virtual VST devices and also external gear (MIDI & synthesizers). Everything is mixed in analog domain. Very often sources of sounds are electric guitar or human voice, which are transformed in totally different forms and functions into traditional musical order.
