Buchla architecture with Moog features

The upper VCO is the main oscillator with a sine waveform and a frequency range of 20 Hz to 5000 Hz. The second oscillator is the modulation oscillator, which reaches the lower audio range at approx. 1300 Hertz and only offers a triangle waveform. This doesn't sound like much in terms of numbers, but all the more so when heard, because frequencies are added to the voltages and new overtones are generated by the effect of the modulation VCO on the main oscillator. The pitch of both oscillators can be modulated via their own generative 8-bit sequencer and one of the two decay envelopes. The elaborately generated sound spectrum is optimally complemented by a ring modulator and a tunable noise generator.

The next step is sound processing, for which Labyrinth provides two options. The wavefolder (VCW) multiplies the waveform of the incoming audio signal within a period. This creates additional overtones in the audio signal. The period duration and therefore the pitch of the signal remain unchanged. By design, Wavefolder works best with waveforms with few overtones such as sine or triangle. The filter (VCF) turns out to be a resonant State-Variable filter that is able to change the character continuously between Lowpass and bandpass. Both units can be modulated separately via one of the two 8-bit sequencers and with the decay envelope 1. The order of VCW and VCF can be adjusted as desired via a toggle switch. This gives you the choice between VCW > VCF, Parallel or VCF > VCW. There is also a VC crossfader to morph between Wavefolder and filter!

The signal path is completed by a VCA, which has a decay envelope and a volume control.

A life of its own, freedom & imaginative details

The colorful mini-buttons and the two LED chains form two generative sequencers that create interlocking sequences that change over time. These are to be understood as a source of constant inspiration; it is not possible to enter specific notes. Of course, there are also a few memory locations and it is also possible to mutate the original sequences. If you prefer to use Labyrinth with a keyboard, analog sequencer or an X0X-style sequencer, you can connect these via MIDI or the corresponding CV/Gate inputs.

As both sequencers generate Gate as well as pitch, Moog has integrated a trigger mixer as a playful detail, which sends the triggers from Seq1, Seq2 or a proportionate Mix of both to the two decay envelopes.

The right-hand quarter of the device is dedicated solely to the 32-socket patch panel. Here you will find all relevant CV, gate, audio and Clock inputs and outputs as well as a TRS input for MIDI. All connections are Eurorack-compatible and are just waiting to exchange functions and be combined with other semi-modular synthesizers. Like Mother-32, DFAM, Spectravox and Subharmonicon Labyrinth can also be removed from its case and inserted into a Eurorack case, where it takes up 60 HP.
