Most of us have two hands so we've put two of them. They are conveniently located on both sides of the case, where no patch cables should be in the way. Each spring-less joystick features 2 outputs (X and Y axis) with attenuverter, allowing you to chose the range and polarity of the ouput CV to precisely match your control needs.
They output +/-5V but can be calibrated to output +/-10V on request.
Japanese ALPS high quality joysticks are used for extra precision and durability.
These are very versatile LFO's, with very wide range, going from almost full stop (several minutes per cycle) to audio frequency range. All of them are voltage controllable through their CV input. They output +/-5V on each waveform.
There come in 3 slightly different flavours:
LFO1 features SAW, SQUARE and TRIANGLE outputs, and a RESET for syncing the start the lfo cycle, useful for creating interesting patterns. The reset input is equipped with a trigger-cleaner circuitry, so you can input whatever signal you want in it. Upon Triggering the waveform will restart from 0V, towards the polarity it was in when reset occurred.
LFO2 features SAW, SQUARE and TRIANGLE outputs, and a MOD potentiometer to attenuate the control voltage input.
LFO3 is slightly more simple, featuring SQUARE and TRIANGLE outputs.
The Sample & Hold tool features an internal voltage controllable CLOCK and a NOISE generation circuitry, normalized to its INPUT. For more info about what a sample and hold does, check here. The clock range from several minutes per cycle to audio-range
There are 2 CV PROCESSORS in the MECHANISM case:
CV PROCESSOR 1 features one INPUT and two buffered identical OUTPUTS. The input goes through an ATTENUVERTER, a SLEW limiter and an OFFSET generator, allowing you to process your CV signals with great precision.
CV PROCESSOR 2 features two INPUTS that are mixed together. The signal then goes to the OFFSET generator and moves on to two buffered identical OUTPUTS. In this processor the SLEW limiter only affects the second input.
The two VCA are identical and have a logarithmic response curve. The LEVEL potentiometer allows you to offset the amplification factor of the VCA. Signal polarization is preserved from INPUT to OUTPUT. If it is your thing, and with pots turned all the way clockwise, the signal can be amplified and distorted (hard clipping).
Thanks for showing interest in MECHANISM eurorack modular case. We've designed it for our own use, but figured that some other people might be also interested so we made a small batch of them. It is not cost effective to produce at this stage and we won't make any money selling it, just recovering some of the initial costs of manufacturing and design. So if you want to buy one for yourself just drop us an email, a Skype, a pigeon or anything.
The price for a fully build, checked, calibrated (according to your taste) and ready to rock unit, is 650 euros. It is available now, don't hesitate to send us a message if you're interested.
Shipping will be quoted according to your delivery address after you contacted us. Extra custom clearance costs may apply but so far nobody reported it.

Eurorack is the commonly acknowledged name in the synth industry for the 3U (rack units) modules, interconnecting them with 3.5mm mono jacks and feeding them with +12 and -12 power rails. Supposedly all the Eurorack modules follow the same electric signal standards, but in reality you'll find that there is a lot of "flexibility" out there. It is not really a problem though.
Doepfer's reintroduction of modular synth in the nineties made use of that standard as it was already in widespread usage in the professional custom electronic cabinet world, and other synth companies followed. It is now the most commonly used standard in the modular synth ecosystem.
Check SDIY's wiki for more tech info.
Because why not ? Eurorack modules were supposed to have only multiple of 2HP of width, but that rule is not really followed anymore as you will find many synth manufacturer releasing modules of 3 or 5 hp. We've noticed also that the miniaturization trend in the eurorack world also pushes in that direction. And finally, because of tolerances and different DIY build qualities, some module configurations are also a bit too tight to fit nicely in your rack so you can see it as an extra HP for convenience.
Of course it is. Just make sure that you test your creations on a different power supply first and that everything goes according to the plan. Our power supply can take some beating, but if you destroy it with sketchy home-made modules, we can detect it easily and won't be able to replace it under the warranty agreement.
Connectors on the power supply PCB have polarizing tabs, preventing incorrect insertion with the mating cable connector, so on our side of things you will be fine. However, to cut costs some module manufacturer provide only regular pin header connectors on their modules. They usually do show on the board where the -12V pin is on the connector. Please make sure that the red stripe of the ribbon cable matches the -12V arrow/indicator. It's not rocket science but you need to check twice that everything look good before turning your rack on. If you experience weird behaviour in your modules as you turn your rack on, turn it off immediately and double check everything. The protected power supply will automatically turn off and on again (like every second) so if all the LED blink in synch and you hear a "click", it means there's a shorted connection somewhere. Remove all the modules and add them one by one to find the culprit.
You can't... at least not without a module called Midi to CV and a midi interface. Check the mighty Modular Grid for some MIDI-TO-CV Modules.
The world as we know it might cease to exist. Well, we truly appreciate your curiosity but if we were you, we would stay away from the trimmers. They calibrate voltages coming out of the tool modules, the range of the LFO speed, and the VCA's symmetry and clipping. If you stored your MECHANISM onto a vibrating device for a few years and want to get it back on track, please contact us and we will send you instructions. But seriously... don't mess up with the trimmers !
Yeah, go for it, it's cool. Just make sure it's not rare and poached wood.
It doesn't really matter. If you don't understand what that number/unit means, just know that MECHANISM should have enough power for any module fitted into it. Unless you want to only use Roland Aira stuff, because those modules are HUNGRY. Having only one or two installed should be fine though.
Whatever really. It depends on your style. The analog tools provide a lot of ways to control your modules already. If you're on a budget we'd say you should get some traditional east-coast core modules like a VCO, a VCF and an ENVELOPE. That will already allow you to have a lot of fun. Try BBD modules and "knob recorders", they're cool. With a bit more budget, check core "voice modules" like the Endorphin.es stuff or digital stuff like the 1010 Music modules. You can't go wrong with those.
Like this :
In reality though, MECHANISM is designed in Hong Kong and Belgium. The electronic PCB's are made in Guangzhou, one of the coolest city on earth, and the metal is crafted in weird but mesmerizing Shenzhen, by those cool hands-in-the-pocket, chain-smoker engineers. The final assembly, soldering and calibration is done at MTBLSM.
Yep, it works absolutely fine as you can see here :
To Normalize a connection means that you're connecting two elements by default.
In the case of MECHANSIM, the noise signal is normalized to the input of the Sample & Hold module because it is the most usual setup and it saves you a patch cable. But by inserting a jack into the INPUT of the Sample & Hold, you break that already established connection and are free to input whatever signal you want.
Well, since there is two outputs on each CV processor, you kind of have some options there... but the real reason is lack of real estate on the analog tools panel. Yeah it would have been nice, we know, but we preferred to offer more active modules instead.
Yes it would... you lucky bastard !
Unplug everything, take a beer in the fridge, go breath outside for a few minutes and then shoot us an email, we'll do our best to help you.
A LFO or VCO is drifting when it's frequency is not super duper stable. In the MECHANISM case, the lack of PCB real estate didn't allow us to implement a temperature compensated circuit for each LFO to stabilize their frequency enough to call is VCO's. But careful design of the signal path, component location and heat-sharing PCB zones have been used to maximise the LFO's stability. Drifting may be a pain in the a** only if you try to maintain oscillators in tune, but LFO-range frequencies are not affected by it. You can of course push the LFO's in the audio range and use it as a VCO's or even for FM effects, but in the latter case they may drift a little bit.
