Vintage Generator
Alt image
Stacks Image 7425
The Vintage Generator has two main oscillators, each with two simultaneous waveform generators.

Oscillator A uses a sine-wave generator and a choice of triangle, saw or pulse, whilst oscillator B uses pulse and triangle generators.

Each oscillator has a variable shape, it is also possible to add drift to the waveform adding greatly to the harmonic content, the outputs of both oscillators are also hard wired to a Ring Modulator with its own output to the mixer.

Each oscillator can be set to track midi data or run in free flow mode.

As well as generating multiple waveforms and ring modulation each oscillator can receive modulation from the VLF Multi Generator and it's independent LFO, plus the Tuned Noise Generator can be used as a modulation source.

The Vintage Generator is a polyphonic design, but the way that the oscillators respond to midi data can be changed between Poly, Mono and Unison.

Switchable hard sync will lock the oscillators together in phase, allowing the modulation and sync sources to still take effect.

VG-1A is used in WRAITH-SQR and VG-1B is used in WARITH-MINI.
VLF Multi

Stacks Image 7578
VLF stands for Very Low Frequency, this is not a general LFO although it can be used as one, it's an oscillator with a lower range than the main oscillators, it is also polyphonic with two independent outputs to the mixer.

The VLF's two waveform generators produce triangle/sine (switchable) and pulse (de-tuneable) and have the same variable shape and drift capabilities.

It can be set to track midi or free run.

The VLF's LFO runs independently and is used as an additional modulation source, it's frequency can be effected by the VLF.
Tuned Noise

Stacks Image 7753
This module generates white and pink noise and has it's own gain control, the pink noise can be passed through a variable band-pass filter.

The output destinations for modulation are osc a-b, vlf a-b plus filter cutoff of Ladder Mode.

It also has it's own output the mixer.
Sequencer Sixteen - Seq 16 M
Alt image
Stacks Image 7806
This is a gate and pitch generating sequencer, when active it will disable gate and pitch information received via midi, any step can be switch in to activate a trigger at that point, each step has control over gate, touch and timbre.

The sequencer will run in poly, mono and unison modes, but it will only generate mono information.

The SEQ 16 M is the master control of the sequencer and is used to adjust the overall settings of gate, touch and timbre, clock rate is adjustable against the main tempo and the direction of the sequencer is also adjustable, any number of steps can be set from 1 to 16, plus you can offset the start position and activate random.

On WRAITH-SQR the poly, mono, unison and glide controls are placed here, they move over to the Vintage Generator for WRAITH-MINI.
Progression
Alt image
Stacks Image 7850
This is a pitch shifting sequencer and is always active whether running or not, it will effect the pitch of the whole synth regardless, including midi input.

Each of the 8 steps alters the glide and pitch of any note information active at that point, each step length can be altered from 1 to 64 beats giving a maximum 512 beats, the number of steps can be set from 2 to 8 plus the clock rate is adjustable against the main tempo, in edit mode the sequencer will sit at the selected step.
Phazed Extract

Stacks Image 7999
This is actually three separate processors that are independently switchable, first in line is Extract.

Extract is four 2-pole filters working against each other to produce a band-pass and a simultaneous band-reject filter, both with resonance, adjusting both the high and low filters will create a band-pass state, by altering the invert dial the filter will crossfade over to a band-reject state.

The output of both the high and low filters are then passed onto two mono phasers each with its own LFO and feedback switch.
Ladder Mode
Alt image
Stacks Image 8086
Three different 4-pole ladder filters, switchable Diode, Transistor and OTA, all with variable cutoff and resonance, each filter has a different feel and response curve.

OTA-2 is placed after the main filters in series and can be switched in to produce an additional 8-pole 48db filter stage.

The filters can be set to follow tracking using the F-Mode switch and also follow the path of the ADSR.

Modulation of the cutoff frequency is set with the MOD-IN dial, Ladder Mode is hard wired to ADSR SIX and it's response is altered with the ADSR dial.
ADSR Six

Stacks Image 8155
The ADSR receives gate and pitch via MIDI or via a sequencer if include with the synth, when triggered it will follow the amplitude path set by the dials.

The way it responds to gate and pitch depends on the settings of the touch and timbre dials.

This is a six stage design with two decays and a variable slope, the ADSR is also hard wired to the J-ESQUE filter of OXYGEN8 and the LADDER MODE of WRAITH.

It will still have an effect when switched off. (i.e. not effecting the amplitude of the synth output but still effecting the filter)
Diff Delay

Stacks Image 8218
The delay uses 8 diffusers to produce stereo delay and reverb effects with switchable feedback regeneration plus low and high filters in the feedback chain.
The Master dial is a separate processor that utilises a fast response limiter for setting the output gain of the synth.
Mix Six

A very simple mixer with inputs from the oscillators, ring modulator and noise generator.

Each input has gain, pan, on/off and a solo switch.
