Bassline

A fully analogue bassline voice in 14 HP from Erica Synths' Drum series: a three-waveform VCO with a transistor sub-oscillator, a BBD-based detune, and an integrated LP/BP VCF and VCA with their own decay envelopes.

Key features

• Fully analogue, 1V/oct tracking from C0 to C8; triangle, square and main outputs at once
• Transistor-based sub-oscillator and BEEF, a BBD-based VCO detune emulation
• LP/BP VCF with resonance, cutoff CV with attenuator, external VCO FM input
• VCF and VCA decay envelopes with their lamps; gate and accent inputs
• Audio output -5 to +5 V; 110 mA on +12 V, 70 mA on -12 V, 35 mm deep
