Notes: Moonwalker is a versatile signal generator that performs as an envelope, lfo, and audio oscillator, with attack and decay time controls

Phase offset is continuously variable from 0 to 360° and inverts the waveform without changing it’s amplitude, and with or without changing it's polarity.

Unipolar mode preserves the output range by offsetting the starting voltage, so it always stays between 0 and +10v

Bipolar mode preserves the starting voltage by offsetting the output range, so it always starts at 0v. The output range will shift from +unipolar, through +bipolar, to -unipolar, through -bipolar back to +unipolar.

The reference waveform does not change phase, but the timing of the rate change between Attack and Decay shift with the phase offset, to ensure synchronous movement.

The phase offset output is half-normalled to the phase offset cv input and skews the waveform from triangle to saw or ramp without changing frequency (when attack = decay).

Notes: Creatively inspiring business from Xaoc as usual. The Erfurt is a digital phase accumulator, digital oscillator, binary counter or clock/audio frequency divider. Versatile stuff.

Supplier's Notes:
Xaoc Devices Erfurt is a digital module that may be used as an 8-output clock and audio frequency divider, a bi-directional binary counter, or a component of the Leibniz binary system, i.e. a programmable digital oscillator.

Erfurt features an 8-bit register which holds its current state: an 8-bit number representing digital values from 0 to 255. The state is available at the front panel via eight binary (5V gate) outputs and reflected by the 8 status LEDs. There are three clock inputs: one incrementing the state at each impulse, one decrementing, and one resetting the state to zero. The state may also be changed manually with two buttons.

When operating alone, the state of Erfurt changes by 1 at each impulse from the clock inputs, so that it counts from 0 to 255 in a cycle (modulo 256). This yields the signal frequency divided by 2, 4, 8, etc. up to 128, available at individual bit outputs. Depending on which clock input is used, the clock patterns correspond to the so called mathematical or musical divisions of the rhythm.

With two different clocks patched to the inputs, the counter alternately increases and decreases its state, and ultimately it counts with a rate proportional to the frequency difference between the clocks. A third clock patched to the Reset input may be used to shorten the sequence thus making the cycle incomplete for even more rhythmic diversity.

When there is a Leibniz data source connected at the back (even as simple as Lipsk), the state increases or decreases in larger steps, depending on the data present at the Leibniz bus (eg. the value programmed by the Lipsk buttons). The counter overflows quicker, and produces more complex patterns.

The state of the counter may be used as a phase input to a digital wave table. Connected to other Leibniz modules, Erfurt may play various roles, eg. it may scan waveshapes in Jena, produce stepped voltages useful for making interesting glissandi with Drezno and any VCO, generate gate patterns animating the spectrum of Odessa harmonic banks, spawn pseudo-chaotic sequences when fed back to Lipsk, etc. Since Erfurt is based on CMOS logic (no CPU!), it can be clocked at very high frequencies (exceeding audio rate), therefore some selection switches are provided for clock pre-scaling.

Notes: Hybrid additive phase-modulation voice on a swappable oscillator platform

Debel Iteritas Alia is a hybrid additive phase-modulation voice inspired by classic and experimental synth sounds from across the decades. Three synthesis algorithms range from classic FM plucks and basses to all-out additive anarchy. DIA features a two-parameter envelope with a huge range of shapes and timing, making it easy to dial in the exact sound you want. With CV over every parameter, a dedicated envelope output, and an absolutely massive timbral range, Debel Iteritas Alia is a powerhouse synth voice in a compact package.

DIA is available on Noise Engineering's 10HP Alia oscillator platform. Buy an Alia module and use the included USB cable to connect to the Noise Engineering Customer Portal to check out any other Alia firmware, free of charge, any time.
