Loki is an all analog design. It features two oscillators designed from the ground up using discrete components. The first oscillator provides independent saw and pulse note-range outputs with FM, PWM, glide and a mixable sub-oscillator. The second oscillator provides an output from low-frequency ranges up to and above audible ranges. The triangle and saw output can be used as an LFO or as a second voice, which can be synced to the note start or the first oscillator waveform.
The voltage controlled filter is based around the analog FatkeysTM SSI2144 filter chip, an updated version of the SSM2044 4-pole low-pass filter used in numerous classic synthesizer designs. The filter design features a resonance path external to the 4 low-pass cores of the SSI2144. This allows resonance to be optionally added to the low-pass response without loss of bass. The filter output is smoothly managed by a custom- designed drive circuit that allows an adjustable amount of punch to be added to the sound.Loki provides an attack/release envelope generator and VCA circuit designed for low-noise operation. The envelope generator has a control input that allows the envelope to track against a modulation source, allowing for velocity/ aftertouch control etc. or more complex envelope shapes.
The second oscillator frequency, filter cutoff and other main controls are provided with larger knobs for live performance. 16 patch connections are provided which are organised by sub-module as an easy cue to their function. The sockets are located towards the bottom of each sub-module to keep cables away from the controls. Loki is simple enough to be patched live, but with enough connections to allow it to be used live or in the studio with a sequencer.
