Intellijel Atlantis
SH-101-inspired dual-oscillator analog synth voice
40 HP Eurorack module
The Atlantis is a complete dual-oscillator subtractive synth voice modeled on the architecture and sound of the Roland SH-101, but built around triangle-core (Dixie) VCOs that respond musically to FM. A primary VCO offers pulse, saw, sine and a switchable sub oscillator; a second MOD oscillator works as an audio VCO or wide-range LFO and also provides S&H and noise. These feed a Roland-style cascaded 2/4-pole multimode (LP/BP/HP) filter with an LP Boost mode, then an ADSR-or-gated VCA into a two-stage output clipping circuit. You can stack up to four pitches at once from the MOD oscillator, VCO, sub and self-resonating filter.
Features
- Roland SH-101-inspired dual-oscillator subtractive synth voice
- Triangle-core (Dixie) primary VCO that responds musically to FM
- Four VCO waveforms: pulse, saw, sine and sub oscillator
- Sub oscillator switchable -1, -2 or stacked -2 octaves below the VCO
- Secondary MOD oscillator usable as audio VCO or wide-range LFO (10-octave range)
- MOD oscillator outputs all waveforms simultaneously plus S&H and noise
- Sample & Hold with selectable Pink/White noise color and external clock input
- Roland-style cascaded 4-pole multimode filter with LP, BP and HP modes
- Switchable 2-pole/4-pole filter slope (12/24 dB per octave)
- LP Boost mode keeps bass prominent at high resonance
- Self-oscillating filter tracks 1V/Oct as a fourth tunable oscillator
- ADSR envelope with x1/x10 time ranges and a cycling LFO mode
