Description
Here's what Intellijel say about the Atlantis:
Inspired by the architecture and sound of the classic Roland SH-101, the Atlantis—just like the 101—is quick to dial in rich bass and lead sounds; only now you have much more sonic territory to explore. Dual VCOs, Multimode VCF, VCA with Drive, and an ADSR envelope, all of the building blocks needed to expand or start making sound in your rack.
Deep Legendary Voice
The Atlantis is an analog, full subtractive synthesizer voice condensed into a single 40HP module that manages to be comprehensive without being cluttered, condensed, or constrained. It gives you all the building blocks needed to start making sounds in eurorack (VCOs, VCF, VCA, and envelope), making it a great starting point or addition to a comprehensive system.
Key Features
- 27 jacks for creative and complex patching options
- Cascaded 4-Pole multimode filter
- Primary VCO: triangle core with Hard Sync, Octave switches, Linear/Exp FM and PWM
- Modulation VCO: triangle core with Hard Sync and Link switch to connect pitch to primary
- Global modulation bus with four VCO waveforms, noise and S&H options
- Looping ADSR with range switch, manual gate, and external level (velocity) control.
- Three position output clipping circuit
- Header on back of PCB that allows it to be linked (normalled) to the Intellijel Metropolis sequencer
- Skiff Friendly
Reimagining A Classic
The Atlantis is inspired by the architecture and sound of the classic Roland SH-101. It has always been one of our favourite synths and we really liked how the seemingly limited architecture allowed for all sorts of creative and musically useful sounds to be easily generated. Just like the 101 it is quick to dial in beautifully rich bass and lead sounds but there is much more sonic territory to explore.
Instead of saw core VCOs, the Atlantis uses triangle core VCOs based on the Dixie, which respond much more musically to FM. The modulation oscillator can be used as an LFO or VCO in audio rates, and both track very precisely over eight or more octaves.
Mixer
In the mixer section you can adjust the balance of the primary oscillator’s waveforms, including a sine wave which is normalled to the EXT IN jack. You can also patch in one of the modulation oscillator’s waveforms into this channel in order to operate the Atlantis as a proper two oscillator synth.
The “LINK”switch enables the modulation VCO pitch to be set as an offset of the primary VCO. This is useful when using it as a stacked dual VCO or when you have the MOD VCO acting as the linear FM source for the primary VCO and wish to maintain the ratio.
Filter
The filter section is a Roland style cascaded 4-pole multimode filter with LP, BP and HP modes. The LP Boost switch engages a special mode useful for the LP that produces a much fatter and prominent sound that is not drowned out by resonance (unlike the original SH-101). The filter self-oscillates to produce a very clean sine wave which also tracks 1V/Oct. Between the Mod VCO, Primary VCO, Sub Oscillator and resonating filter it is possible to layer up to four different pitches at one time.
