VORTEX USER MANUAL

by Simon De Rycke / BRiES

Thank you for purchasing VORTEX by Cosmotronic. VORTEX is a versatile analog

dual triangle core complex oscillator with a wide frequency range, a lot of timbral

shaping options, useful normalizations, CV inputs for every parameter and

attenuators to control the amounts of both internal and external modulation.

Contents of the box:

width:

26HP
