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.

Features

• 8-voice polyphony
• Multi-timbral physical modeling
• True stereo outputs
• Configurable spatialization modes
• Plucked strings models
• Prepared piano models
• Tuned percussion models
