Qu-Bit Electronix Surface 2
Multi-timbral physical modeling voice with spatial synthesis
10 HP Eurorack module
Surface is a multi-timbral physical modeling voice that emulates acoustic instruments like plucked strings, prepared piano, and melodic percussion, or morphs into synthetic textures. With 8-voice polyphony and true stereo outputs, it blurs the line between emulation and synthesis to create entirely new worlds of sound.
