"This seems to be also one of the "older" modules from the series. It works fine without any issue.

Reason why the module is called “polyphonic” is because it can output 4 different type of voltage “envelope” at the same time.

More info about this module here and here"

"The PlanB model 10 is a multifunctional module, not only a simple envelope.
The name “polyphonic envelope” does not describe the functions of this great module, the reason why they called it “polyphonic” is because it can output 4 different type of voltage “envelope” at the same time.
In fact the M10 is way more versatile than an envelope, this is really similar to the Bananalogue VCS module, a multitask voltage controlled cv generator .

The main task is the ENVELOPE.
The envelope consist of an AD env with RISE (0.5 ms-5 min attack)and FALL (0.5 ms – 5 min decay/release) controlled not by gate signals but by Triggers.
The attack and decay time can stretched x8 times their duration with the TIMEBASE control knob (so the complete envelope can last from 0.5 milliseconds to 20 minutes).
You can stretch the time manually just turning the knob or controlling it with the VC TB (voltage control timebase).
The VC TB can act in positive or negative, so it can add or subtract.
Than there is the level of the env, which is bipolar too , so it can act as a positive or inverted envelope.
On the left there are the 5 connectors for the 4 different envelopes generated:

EOC
EOA
RAMP
2x AD (with ad contour switch)
The AD acts as the classic “trig” envelope, with 3 different contour (log, lin, exp).
The RAMP is a ramp with rise time 2x the RISE control time.
The EOA is a sustained square which falls when receive a trig and performs the AD cycle at the “End Of Attack”.
The EOC acts as the EOA but the AD starts at the End Of Contour.

LFO MODE

The rise-fall cycle can be looped and can also work as an lfo.
Using the rise and fall it can produce various waveform between the tri, square, saw, ramp…
The interesting thing is that the timebase knob can control the time of the lfo, so it a vc lfo, the other thing that can lead to creative results is the fact that the rate of the lfo is not controlled by the timebase only, but it ’s a mix of the rise and fall time.
So the shorter is the R&F the faster will be the lfo rate.

VCO MODE

The third interesting mode is the vco function.
The module has a triangle-core , so it can sound useful even as a vco.
To get the vco mode you have to switch into LFO and use fast R&F time and “tune” the oscillator with the timebase function and VC TB to control it with a keyboard cv.
It does not reach very high frequencies but can be used on the low and mid range as an audio modulator or a audio source.

TIPS:
I noticed two useful tips:

As the core is a TRI-core the envelope create a sort of clip when, reached the max value,start the fall.
To avoid the clip it’s useful to use a lowpass filter post the VCA.
In LFO mode don’t connect any source to the trig in because the summing of the two sources can damage the module , too high voltage!"

"Back to where it all started.

No eye candy or wooden ends etc. I wanted substance over superficiality. As much as i enjoyed doing the larger machines and will probably do more when i think i've something signifigant to add again (like midi / adsr etc) i started to feel that the curious aspect of these little instruments that sparked my interest was getting lost in some kind of pseudo synthesizer territory to the point where i might as well have just moved on to total synth diy and ditched working on these things. I've taken what i've learned along the way and what i can do now, miniaturised it all for purpose and put it to work with the fundamentals of the circuit bending that bought me to where i am and what i can do now. The charm and fun of a bespoke circuit bent keyboard but with a sound that stretches from vanilla to hell.

I wanted a compact machine which made space very limited. So i opted to ditch all the drum mute/distortion bends and keep just the pitch control bend which is so easily applied to these. Grunge bossa nova and disco get old fast. I wanted this to be something you could sample the hell out of for trashed up noise and quirky analogue hits and sounds. It's heart revolves around additional circuitry. An embedded psu/supressor to power the keyboard, filter and delay efficiently and of course the filter and delay themselves. It also has a CV input around the side that allows you to modulate the filter cutoff via other equipment. In this case a sequential circuits Pro 1 with note sequences programmed to send out cv patterns.

The intro to this video was made using samples from this machine and the sampler/fx processing of propellerheads reason. Probably most apparent as the intro peaks with the delay crash.

I think i've got it right and i think this is something different and diverse within the realm. But i suppose like most things it's a matter of taste as to if you like this particular flavour or not :)"

Modifications and embedded circuitry:

Analogue resonant filter with high pass and low pass bands
Gain, resonance, low pass/high pass toggle and cutoff
A brilliant filter based on the synthacon.
Lot's of resonance and a unique character.

Digital 'death industrial' delay
Rate, noise, feedback, off/on toggle
This delay variant is based on what i've learned from modifying delay pedals in the past.
Quite an aggressive version that can dial up some serious noise as well as act as a pseudo reverb/conventional echo.

PSU - DC hum suppression circuitry
A regulated psu is now built into the machine.
This gives a stable and quiet power supply to both the keyboard and additional circuitry as well as
providing a quiet output and excellent noise floor.
Input voltage is 9 - 12V
Since filming the video the master power switch has been moved from the side of the machine to the top control panel which is a better position and looks neater.

Control voltage input to filter cutoff
3.5mm jack. Allows you to hook the casio up to your cv enabled equipment to modulate the filter.
Examples of this are shown in the demo video.
The cv modulation is provided by a sequential circuits pro1.

Master pitch control
Gives a large global pitch range - demonstrated in the demo video
Since filming the video a body contact has been added to the side of the machine which gives a handy way of pitch bending and modulation.

Arturia MicroBrute SE Demo - 15th anniv.

"Arturia MicroBrute SE Demo - 15th anniv."

Update and the official press release:

"Arturia makes colourful analogue waves with massive-sounding SE edition of miniature MicroBrute

'This mighty little machine runs the gamut from metallic, brutal bass to velvety bleepy, bloopy goodness — sheer joy to play. The single oscillator is wildly diverse — wait ’til you meet the Metalizer and Ultrasaw, and I love the SEQUENCER and MOD MATRIX — very inspiring!'

- Tara Busch (I Speak Machine, 2014)


GRENOBLE, FRANCE: music software and hardware company Arturia is proud to announce availability of MicroBrute SE — a ‘special edition’ of its widely-acclaimed MicroBrute Analog Synthesizer, available in a choice of three tempting colours to suit whatever playful mood might make anyone’s musical day, be it Christmas or otherwise — as of October 15...

Arturia’s award-winning MiniBrute Analog Synthesizer rapidly reset the price/performance ratio benchmark when soaring through the subtractive synthesis sound barrier upon being launched in 2012 to much critical acclaim and subsequent success. Afterwards, Arturia built upon that success last year when introducing a ‘special edition’ of its namesake sibling, the MiniBrute SE, sharing the same physical footprint, but building upon this amazingly compact and bijou analogue monosynth in both looks and features. That same year, Arturia adventurously took the ‘shrinking synth’ concept one step further with its equally big-sounding little-brother, the MicroBrute Analog Synthesizer, an even smaller semi-modular monosynth with inbuilt step sequencer, boasting MIDI, USB, and CV connectivity with a whole host of unique features — guaranteed to bring big smiles to go with those massive sounds! Similarly, today the MicroBrute has been given the ‘special edition’ treatment to become the MicroBrute SE — same physical footprint and full feature set! So what’s with those colours? Blue, orange, or white, they all sound the same... that is to say, sounds massive. But who’s to say you can’t make a bold style statement with a massive-sounding synthesizer, however small it may be? Thanks to the colourful MicroBrute SE, now you can!

But beneath those colourful, compact and bijou bonnets resides a living and breathing, fully-fledged analogue synthesizer that belies its diminutive dimensions and is actually anything but basic. For starters, just like its MiniBrute SE bigger brother, the OSCILLATOR that beats at its musical heart features SAW, TRIANGLE, and SQUARE waveforms that are all mixable to help shape the resulting sound without the limitations imposed by comparable contemporary and vintage synths alike. Additionally, the new Overtone oscillator generates additional harmonic content, ranging from one octave down to a fifth above the base OSCILLATOR pitch, while the Sub > Fifth control can continuously sweep spectrum. Moreover, Metalizer adds complex harmonics to the TRIANGLE waveform for creating harsh, harmonically-rich sounds, while Ultrasaw adds a lively and bright ensemble effect to the SAWTOOTH waveform — perfect for crafting sounds suited to dance anthems. And let’s not forget the all-important Pulse Width control for creating nasal-thin tones or rich square sounds. Simply speaking, never before has such a small, single-oscillator synth sounded so big... or looked so good!

Of course, filtering helps shape any analogue synth’s sound — be it big or small, and here the MicroBrute SE definitely does not disappoint. Indeed, its distinctive-sounding Steiner-Parker FILTER plays a big part in helping give the MicroBrute SE a unique sound — again, just like its big brother. This filter design dates back to the Steiner-Parker Synthacon, an analogue monosynth built by the namesake Salt Lake City-based synth manufacturer between 1975 and 1979. Its HP (high-pass), BP (bandpass), and LP (lowpass) modes make for far more filtering flexibility than that found in synths many times the price! And that’s before factoring Arturia’s acclaimed Brute FactorTM into the musical equation, adding anything from subtle overdrive to full-blown intermodulation havoc — choose your settings, and let the fun begin!

Speaking of having fun, the eight-Pattern step SEQUENCER is an almost endless source of inspiration and rhythmic creativity — step input notes and rests to create storable sequences that can be played back and switched between on the fly at a variable Rate or synchronised to external MIDI clock. Meanwhile, MIDI, USB, and CV GATE connectivity, of course, combine to ensure that the MicroBrute SE is ready and willing to talk to the outside electronic musical instrument world, wherever it may find itself. It’s even blessed with an external audio Input with an adjustable Input Level control, so why not use it to process whatever you feel like sticking into its 1/4-inch socket — within reason, of course!

The front panel-mounted MOD MATRIX moreover allows adventurous users to control many aspects of the MicroBrute SE’s massive-sounding single voice for different internal sources, as well as controlling them via external synths and modules. MicroBrute SE comes complete with two stackable jack cables for that very purpose. Preset sheets also come as standard, so no need to worry about forgetting those adventurous sound settings!

With a space-saving 25-note mini-keyboard and weighing in at only 1.75kg, the MicroBrute SE is as compact as it is colourful, yet positively punches well above its weight with a rip-roaring analogue sound spanning woofer-flapping bass, screaming leads, ear-opening effects, wave-folded growls, punchy drum sounds galore, and much in-between and beyond. Pick one — or even all three — up from an authorised Arturia dealer or retailer today! To make this perfectly portable package even more portable, Arturia has helpfully included a stylish carry bag guaranteed to turn heads wherever the stylish synth goes. Go ahead. Make a bold style statement while making a massive sound!


A ‘limited’ run of 4,000 MicroBrute SE units are available for purchase in a choice of three tempting colours through Arturia’s global network of dealers and retailers for €329.00 EUR/$329.00 USD.
