Erica Graphic VCO on Modulargrid
One of the greatest music producer of our times - Randall Dunn recently wrote a little piece about sounds he love. He says: “We were both pretty hungry in Michigan in the 80's looking for new sounds and music. [..] Mostly played on Synclavier and a Roland JD 800 I began a strange love affair with late era digital synths like those and the PPG wave and why sometimes I still prefer the brutality of a wavetable to a Minimoog.” 
Of course, everybody loves sound of an analogue synth. It is a non-questionable core value of huge and influential tradition started in the second part of 20th century. However, if you are bored just for a minute to take part in that old collective ritual of millions, if you feel that rebel growing inside of you, if you are hungry to discover your own path, your own signature sound, if you really would love to jump into tomorrow now…, then Graphic VCO is your necessary ally. Draw your own waveforms. Sculpt your own voice. Master your own musical gesture. And you may find yourself in a new beautiful world. Indeed. 
As Leonardo once said: “If I had a Graphic VCO I would have never wasted so much time with those noiseless paintings…”
