Arturia MiniBrute 2 and the “Synth-Flation” phenomenon The Arturia MiniBrute 2 could easily be chosen “People’s-Analog-Synthesizer Number ONE of the decade”. It certainly has all the refinements that a modern versatile analog synth should have. But in truth, its award may be out of reach, since the market is going through an odd phase of inflation at the moment. W hile “Inflation” is indicative of money, we could coin the term “Synth-Flation” to explain what’s going on: The artificial expansion of the synth market. Foremost among the competitors, the MiniBrute 2, an excellent sounding 2- VCO synthesizer from the French synth manufacturer Arturia. The fact is, if the market were dominated by the veterans of the category “Vintage Synthesizer”, the release of MiniBrute 2 would see masses of enthusiasts around the globe, stampeding to the music stores. They would desert their jobs, friends and family and jump on already overcrowded trains to get to cities where they could buy the MiniBrute 2 (or at least see their object of desire). But that’s just not the way it’s happening … | 1 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon After the original MiniBrute had experienced an entirely respectable output of production, after MicroBrute and MatrixBrute had been introduced into Arturia’s portfolio, and after many dozens of analog instruments of various producers had appeared on the market, MiniBrute 2 has become just one of numerous analog synths in 2019. The fact that the MiniBrute 2 is selling well, but not in extraordinary quantities, the fact that it’s not a top-seller, so to speak, is a fate that the instrument suffers unfairly. Neither its excellent sound, nor its wonderful concept, nor its balanced price/performance ratio explain the fact that it hasn’t risen to the “People’s-Analog-Synthesizer Number ONE”. But whether things change for the better has yet to be seen. Without a doubt, Arturia has done everything right, and the MiniBrute 2 is indeed an almost perfect compact modern analog synth. | 2 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon The MiniBrute 2’s three areas of excellence The MiniBrute 2 concept involves 3 areas: Sound Engine (Synthesizer), Performance Area (Sequencer, Arpeggiator, Wheels) and the Interfacing Section (48-point patchbay plus the optional RackBrute System expansion). Sound Engine The synthesizer in short. MiniBrute 2 has: 2 oscillators / VCOs (with noise) 1 MultiMode filter / VCF 2 envelopes (ADSR and AD) 1 amplifier / VCA 2 LFOs 2 oscillators / VCOs The main oscillator – VCO 1 – has been known since the original MiniBrute. Three waveforms can be mixed independently and there is noise as well as “external audio” input. All well-known qualities such as PWM, Metalizer or Ultrasaw can be found as well as the newly-added cross modulation – FM by VCO 2 (!). | 3 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon The latter is much simpler than VCO 1. VCO 2 has a slimmed-down hardware design (a toggle switch to choose between waveforms instead of sliders for waveform mixing). And there is no PWM or other extra. But VCO 2 can be set to Low Frequency and thus be used as an extra LFO. And by chosing frequency range ALL you can sweep throughout the entire audio range with the turn of a knob – excellent! Finally, FINE tuning allows for beats and interval-adjustments. 1 MultiMode filter / VCF The Arturia MultiMode filter offers LowPass, HighPass, BandPass and Notch. The associated ADSR envelope and modulation wheel are pre-wired to control the filter frequency, and LFO 1 is internally routed to filter resonance (RM – resonance modulation). | 4 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon 2 envelopes (ADSR and AD) Besides the ADSR from the filter area, there’s an AD envelope in the VCA section. Although small in size, it offers quite a few extras (an interesting parallel to the minimalistic VCO 2). First and foremost the loop function, another great facet to the MiniBrute 2 in terms of modulation variety … the loop-AD in addition to LFO 1, LFO 2 and VCO 2 (which can – once more – be used in low frequency mode). But there is even more: Attack and Decay can be voltage- controlled (!) – the two related CV-inputs are found in the patch area. 1 amplifier / VCA In addition to the above-mentioned AD envelope, the VCA options include that important (and Arturia-typical) BRUTE knob. A simple, yet effective function for output signal distortion. Then there’s GLOBAL TUNE … for overall pitch adjustments in the studio or on stage (or for detuning two MiniBrute 2 against each other, just as an example). The ATT 2 > AMP knob, by the way, opens the amplifier permanently – so you can program a sound with both hands. | 5 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon 2 LFOs Each LFO offers 6 waveforms (including random stepped / random gliding). The frequency ranges from 0,0625 Hertz (one cycle every 16 seconds!) up to 100 Hertz (audio range). The SYNC switch sets the LFO rate’s operating mode – it can be synchronized to the Sequencer/ Arpeggiator (Seq) or set to FREE mode (free running LFO). Performance Area Unlike the original MiniBrute, the wheels are now placed “right next to” the keyboard. Which, of course, improves performance. And these are no cheap plastic-wheels, but solid aluminum wheels, slightly ribbed and a pleasure to operate. Pitchbend range can be adjusted to up to one octave, further increase of the audio range can be achieved by the key transpose function (+/- several octaves). The Modulation Wheel (or – alternatively – Aftertouch!) can be used for LFO 1 modulation (“Vibrato”), and/or as a source for filter frequency modulation, or as a global CV-source in the patch-bay. | 6 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon Sequencer and Arpeggiator are equipped with a variety of playing modes / directions, clock divisions, gate lengths and swing factors. The two latter functions are activated by means of the SHIFT function via the keyboard keys (see the terms in blue above the keyboard). You can record eight different sequences, each with up to 64 steps and Sequ / Arp synchronization can be done internally, via USB, MIDI or via (analog) Clock. At this point we have to mention the MiniBrute 2S. It has no standard keyboard, but 16 pressure- and velocity- sensitive pads that can be used as a keyboard or to program the sequencer. The expanded sequencer controls Pitch, Gate, Velocity and Pressure. While Seq 1 is for notes, Seq 2 and Seq 3 can generate other types of signals: Gates, CV, Pitch, LFOs, Envelopes. Real-time and step-editing are available. It’s amazing how flexible the MiniBrute 2S really is … | 7 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon Interfacing Section In addition to the usual INs/OUTs à la MIDI, USB and Audio, there’s a huge 48-point patch panel – THE highlight of MiniBrute 2. “The MiniBrute 2 is an impressive synthesizer with a powerful set of analog circuitry […]. But with the addition of the patch bay the MiniBrute 2 ranks with modular synthesizers many times its size.” (Arturia, MiniBrute 2 User Manual, page 53) Optimally located to the right of the user panel, the patchbay not only expands the MiniBrute 2’s (internal) sonic possibilities, but also opens to the world of (external) modular synths – both to vintage semi-modulars (ARP-2600, Roland System-100M, etc.) and to modern instruments / devices (Eurorack modules). And there are some extra extras as well: the patchbay includes an inverter and a cute MIDI-to-CV interface (with outputs for CV, Gate, VEL and MOD-wheel). Perfect! | 8 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon Two small criticisms must uttered none the less. First, the patch panel labelling. It is as follows: blue printing (pre- wired connections) above the sockets, white printing (in/outputs) below. In the synthesizer section, however, all names are printed below the knobs, in 2 rows, white labelling on top, blue labelling at the bottom … which is just the other way round as in the patchbay area. It’s a bit confusing, no? Second, there are no multiple sockets. Granted, the patch panel is very crowded. We could not tell where to put multiples. Nonetheless, some signal splitting is always necessary when it comes to wiring a patchbay, so we wonder why Arturia didn’t implement a dedicated multiples-area (2×3 and 1×4 multiples, for example). In Practice Those who believe that a modern analog synth has by nature limited sound potential are in for a surprise. Actually, just the opposite is true (whereby the topic of “sound character” must be debated somewhere else). The Arturia MiniBrute 2 is extremely versatile with excellent sound potential. The musician needs a very long time to even reach its musical peripheries. Peripheries that then can be pushed back (nearly) infinitely with the optional RackBrute Eurorack expansion. | 9 Arturia MiniBrute 2 and the “Synth-Flation” phenomenon What do we mean by “excellent sound”? MiniBrute 2 entirely fullfills the demands of analog sound art. Ok, ok … almost. We’ll get around to its few limitations later. The SOUND is well-balanced throughout the audio range. Powerful 2-VCO-sequencing, fat basses, silverly shimmering lead sounds with vibrato, spacy x-mod effect sound creations … what more could the heart desire? The musical workflow is enhanced by well-thought-out pre-wiring and performance options (e.g. vibrato-LFO and/or VCF-modulation by the mod-wheel) and many other details. Subtle beats, massive (Brute) saturations, spectacular filter sweeps … If you can imagine it, MiniBrute 2 has it! [A little story on the side.
