Spaceman Effects Delta II
The Spaceman Effects Delta II is an inspired optical harmonic tremolo with extensive tone shaping and rhythmic capabilities.
Craft harmonic, and traditional tremolo sounds that stagger, hop, buzz, ripple, and swirl with unparalleled variety using a brilliantly simple LFO interface. Soar through the sonic scenery as evolving rhythms throb and pulse like stars flickering across the cosmos.
The Delta II splits the input signal into high and low-frequency bands to achieve harmonic tremolo. It then amplitude modulates the split signal in opposite directions.
As the low frequencies pass, the highs are cut, and as the highs fade back into the mix, the lows sink below the horizon.
Since one of the frequency bands is always passing, it’s less choppy than typical for trem.
Morph between harmonic and traditional tremolo with the innovative LAG control, which introduces a variable offset between the LFO’s dual outputs. Combined with the Delta II’s unique voices, this makes for great swirling, phasey tones with endless rhythmic possibilities.
The Delta II features a high headroom all analogue signal path with expanded tone shaping abilities.
The signal is buffered, and fed into a 2-pole state-variable filter which performs the frequency range split.
The high-pass, and low-pass filter outputs, along with the dry signal are then fed into the tremolo portion of the circuit. The optical elements in the Delta II make for a smooth rise and decay, with a clean fluid response.
The VOICE toggle offers three signal path modulation options.
High and Dry
This highlights top-end shimmer, and emphasises clarity and bite. High & Low – provides a more liquid tonality especially useful for swirling phasey sounds. Low & Dry – excels at dark throbbing low-end presence. Exploration of the DEPTH, FREQ, and RES controls will unearth filtery stabs, slithering vibrato, or robotic rhythms.
Volume is set at unity gain but can be fine-tuned via the internal trimpot. Each portion of the Delta II is carefully thoughtout, and painstakingly executed to be beautifully colored and alive with rhythmic intensity, and effortless shimmer.
FALL BEHIND IN PERFECT TIME
The LFO of the Delta II is deceptively simple, yet surprisingly versatile. The dual output triangle wave oscillator has a unique ability – Lag.
This allows the outputs of the LFO to smoothly lag from 0-180 degrees out of phase while still being in time.
What this means is that with LAG control at minimum the two LFO outputs are identical, and at maximum LAG, they alternate in opposing fashion.
For traditional tremolo sounds, keep the LAG at a minimum, then as you introduce LAG, the LFO outputs diverge, creating infinite shades of harmonic tremolo up to maximum.
The middle ranges of this control can thump, pulse, beat, bunnyhop, stagger, and dance in any given instance. Modulate the LFO RATE or DEPTH via expression or CV.
