The first instrument by MFB, which also looks as good as it sounds, before that the company used modest housings of cheap materials for its instruments. Dominion X is assembled within a metal housing with wooden sides and has, perhaps, everything necessary to be called an "analog synthesizer module for the 21st century".
MFB Dominion X has the architecture which has already become standard for modern analog synthesizers: the microprocessor controls the analog path. Such a structure provides reliability, simplifies control and extends the capabilities of an analog synthesizer.
Dominion X contains three identical voltage-controlled oscillators (VCO), which produce triangular, sawtooth and rectangular waveforms. In the "PW" mode, the basic wave can be transformed: a triangle into a sine, a saw - triangle, a meander - a pulsating wave with a controlled duty cycle. Pulse-width modes (PWM from LFO1), frequency (FM from VCO3) and ring modulation ("ring" multiplication of VCO signals) are also available.
For each oscillator, an octave switch, a modulation depth controller, and a microtuning controller are provided.
In the mixer section, the signal level from the three VCOs and the noise source or external source is set.
The voltage-controlled filter (VCF) has several operating modes:
- Two-stage low-pass filter (LPF) with a slope of 12 dB per octave.
- Three-stage LPF - 18 dB / oct.
- The four-stage LPF is 24 dB / oct.
- High-pass filter 12 dB / oct.
- Bandpass filter 12 dB / oct.
- Notch filter 6 dB / oct.
VCF has resonance, cutoff and modulation depth adjustments from the ADSR envelope generator. Use the "Key" button to set the keyboard tracking mode (higher notes have a higher cutoff frequency). LFO1, LFO2, VCO2 or VCO3 can be the filter modulation source.
An interesting detail observed in Dominion X - the "feedback" regulator, which allows to send a signal from the synthesizer output back to the filter section.
Two modulatable low frequency (LFO) oscillators produce a sine, triangular, sawtooth, inverse, square and S&H waveforms. For each of them, a reset mode is provided for the start of each new note.
The third LFO "MOD" is designed to work in conjunction with the commands of the modulation wheel. It produces a triangular wave that can be directed to modulate VCO, VCF, VCA.
For integration with modular systems, MFB Dominion X has nine mini jack inputs for control signals.
You can save the synthesizer settings to one of 128 memory locations.
