Wavefonix

Notes: The 1847 Wavetable Oscillator (VCDO) is a versatile and easy-to-use voltage-controlled 8-bit wavetable oscillator.

The main oscillator has 16 waveforms arranged as a wavetable and a sub-oscillator also provides 8 waveforms; each selectable at one of four octaves (+1, unison, -1 or -2). The main and sub-oscillator wavetables can be cycled through manually using knobs on the front panel, or can each be controlled by a CV source. The main oscillator waveform select CV has its own dedicated attenuator.

Two FM CV inputs are also provided (FM 1 has an attenuator), along with a 1V/octave input (quantized to semitones).

Coarse and fine frequency controls are provided. The overall frequency range of the oscillator is ten octaves i.e. 8.18Hz to 8,372Hz (MIDI note 0 to 120).

Other features include a bitcrush effect; allowing the sample resolution of the output to be varied between 1-bit and 8-bit. This is controllable via a knob on the front panel and a separate CV input.

Controllable glide allows portamento to be introduced when the oscillator is controlled by a keyboard.

Notes: Wavefonix's 3340 Low-Frequency Oscillator (LFO) utilises the original CEM3340 (Rev. G) architecture, similarly to the 3340 VCO.

It is a voltage-controlled LFO featuring three simultaneous, buffered 10Vpp (i5V) waveforms including DC-coupled ramp, triangle and pulse outputs.

The pulse output has a controllable PW, along with a PWM CV input (i5V range). The PW can be varied manually between 50% and 100% duty cycle with the PW knob on the front panel. When a PWM CV source is input, the PW is normalled to 50% and the CV level is attenuated using the PW knob.

Other features include a controllable FM input that is also calibrated to 1V/octave when the FM knob is fully-clockwise. So the LFO can also be used as a limited VCO. A comparator-based reversing type sync input also allows the LFO to be synced to another LFO or VCO etc.

The overall frequency range of the LFO is approximately 0.03Hz to 4.5kHz. Coarse and fine frequency knobs provide a maximum frequency adjustment range of approximately 0.03Hz to 1kHZ (this range is adjustable using a trimmer on the PCB).

Notes: This module is a premium, buffered version of our passive 4x4 multiple, featuring four groups of buffered multiples; each group having one input and three outputs.

Buffered multiples are useful for multiplying pitch sensitive CV signals, such as 1V/octave CVs from a keyboard or MIDI to CV converter, although they can also be used for multiplying CV signals from other sources, such as LFOs etc.

Passive multiples are not particularly suitable for use with pitch sensitive CVs, as they often result in a loss of tuning. Buffered multiples ensure that any loss in pitch is negligible.

This allows for a wide range of sonic and modulation possibilities when combined with other modules e.g. white noise can be used to produce hi-hat sounds or the random LF noise can be input into a sample and hold module to produce random, retro-style beeps etc.

Each output features its own dedicated attenuator. The random LF output also has a green LED indicator, providing a visual representation of the output level.

The maximum peak-to-peak amplitude of each noise output is approximately 10V (i5V).

Notes: The R2R DAC is an ingenious design. It consists of a string of resistors connected to another set of resistors. There are no active components in this module and it provides an affordable and easy way of converting digital signals to analog signals with great accuracy.

Digital-to analog conversion with the R2R is straight-forward. Inputting a digital signal into any of the eight data inputs (1 to 128 in binary) will provide an analog output from the In/Out socket.

Waveform's Clock Divider (CD) module complements the R2R DAC very well. For example; inputting various combinations of clock signals from the Clock Divider into the 1 to 128 inputs of the R2R DAC provides some interesting outputs from the In/Out, such as a stepped ramp wave. The number of input signals determines the resolution i.e. there are eight inputs (each corresponding to a bit), so therefore the maximum resolution is 8-bit. The resulting output can be fed into the CV input of a VCO, LFO, quantizer, filter and many other modules. There are many different combinations that can be experimented with.

Other uses for the R2R DAC include as an 8-channel mixer by inputting analog signals into any of the 8 inputs (1 being the quietest and 128 being the loudest) and the resultant mixed signal is given from the In/Out.

Similarly, the module can be used as an attenuator and multiple by inputting a signal into the In/Out and the attenuated signals are output from the eight binary inputs (again with 1 being the most attenuated and 128 being the least attenuated).
