Belgrad

An all-analog dual peak multimode state variable filter in 14 HP: two state variable cores combined in series and parallel give ten responses, from double-slope lowpass to double-slope highpass through notches and bandpasses, each with two resonant peaks whose distance (SPAN), balance and resonance are voltage controlled. Input level up to overdrive, self-oscillation tracking V/oct, and the TITO switch for self or cross-modulation of the cores.

Key features

• MODE: ten responses LL, LB, NL, NN, LH, BB, HL, HN, BH, HH
• FREQ from about 4 Hz to 28 kHz, V-OCT and FM with its lit slider
• RESO (0 to 8 V CV), BALANCE between the peaks (±5 V CV), SPAN up to nearly eight octaves with its lit slider
• TITO: neutral, self-modulation (SM) or cross-modulation (XM)
• LEVEL from clean to overdrive
