Atlantis

Description

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.

Inspired by the architecture and sound of the classic Roland SH-101. The Atlantis 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.

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.

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.

The envelope section is an ADSR with a dual range switch. It also can be set to a looping mode which can be gated on/off externally.

The output VCA feeds into a two level output clipping circuit that you can use to get a much ballsier/dirtier sound.
