Elektron Musical Instruments

wow : )  are you working with elektron ??

lets start a STARTUP  company  !!!   i have a program that says "learn c c++ 
in 5 days "   : )

will make  synthesizers (soft/hard) with waves with totally different values 
!!!
LETS  CHANGE  THE MARKET !!!!
even the SIDSTATION became a "best-seller"  and uesed on several monster 
hits !! (log to sidstation.com  /sounds
hear >> zombie nation , sandman psychotoons  etc...  to understand !!! : )

or i'll just fligh to moscow (again)and look for old KGB synths  hehehe
cheers
izik sandman

its a dog eat dog world out there , but from where i stand there aint enough 
DAMN DOGS
