Hi do i need to caliber the psu ? I have +11.90V -12V and 5.105V Do i need to link the rails on my wooden case to the ground ? you calibrate the +12v to +12.0v you calibrate the -12v to -12.0v the 5v is not adjustable. +5.105v is good. anything from +4.98v to 5.2v is good for a 7805 regulator. ther...

listen to this in the dark or eyes closed so you can focus on the music

I avoided this issue like the plague and have made sure I have a 1/4” out somewhere. The 1/8” ones always end up bent after a while from someone stepping on the cable or worse. That being said I’m pretty sure Sweetwater has what you need.

there are a few things. the modulator must be silent and it must have no DC offset. if you have a passive diode ring, your diodes must have perfectly matched Vf. if you have an active design probably it is based on the AD633 four quadrant multiplier. if it is really old technology then it may be a M...

I read the entire manual to the USTA. I have a million good ideas. most important would be to use the interpolation between steps to morph between different sounds. even if you play keys, you can use the gate out from the keyboard to trigger the next step in the sequencer. you have 4 channels that c...

What kind of flying attenuators do you have? Been considering digging into my bag of pots and jacks and trying to make some myself. Or maybe building some ST Modular workmate modules ... I have these discontinued attenuators https://www.muffwiggler.com/forum/viewtopic.php?t=120808 but you can buy t...

If you calculate the percentage of area that is wasted on rails you will see that 3U does not waste space. Keeping everything in the 3U means you can buy whatever you need and put it anywhere in the case. I have flying attenuators and 2HP mults all over. The flying attenuators really reduced the mes...

Maybe the abstract data octocontroler?

I understand now. you have two AC adapters each feeding a MFOS power supply each feeding a single bus board. but each ground is completely independent of the other ground. call them G1 and G2. mains earth is not connected to G1 or G2. G1 is not connected to G2 etc.. if you flip the bus board over an...

this is a grounding issue. your ground wires should be shorter and thicker, all connected at one location on the power supply, if you daisy chained the ground from one bus board to the other bus board and you over loaded your 500mA limit then yes you can have problems with power rail noise. from the...

Ableton is excellent at reducing the amount of samples in RAM and CPU if you deactivate or mute a track or sample. If you freeze a track then it renders the sounds of the plugins and unloads them automatically. Ableton does load enough of the beginning of every sample into RAM so that you get almost...

Meta is 12HP. Take a read through to see what it can do. You can also reprogram it.

I misunderstood what addac module that was. Without a link to modular grid I only have a low quality picture. I thought it was the transformer balanced out from addac. I see now that it is a format jumbler.

How do you define conductive? All thermal compounds are a little bit conductive. Even the carbon fiber particles are conductive and capacitive. This is true for thermal grease or thermal epoxy. It depends on your exact requirements. If you need > 100M resistance then you should use conformal coating...

Compare the broken thing to a working one.

Post pictures or at least a hand drawn wiring diagram. Post links to the bus boards, power supply etc..

The AC mains loads are always in parallel but you can decide if you do a star distribution or if you daisy chain your mains AC. You could theoretically wire two 120V AC mains transformers in series for 240V AC but that would be a super bad idea that you should never ever do.

That's a great little system but you should take out the intelijel out and swap in the ALM headphone and a doepfer 4HP 4 input mixer. I also think you should get a 2HP buffered mult and a 2HP attenuator. You probably want an attenuator before the addac. It depends what kind of console or audio inter...

After you buy the pre-cut rails, crimp tools, multimeter, spools of wire, soldering iron, misc mounting hardware etc.. you pay almost as much as you would to buy a cheap used case. You can also factor in your time to build it. the cheapest 12U you can build is about $400 but it could be up to $800 i...

that's a big rack

I would definitely look into pan and fade modules. you have the space to fit this one. it manages the equal power (RMS) problem for audio mixing.

This is ETIT :wink: The matrix mixer is sold out till I can make more some time in the future. I have done a lot of feedback. I will give you a list of modules I like for feedback. I am not a fan of having fixed frequency bands like on the resonant EQ. everyone loves it but they are all squeaking at...

hypster or zadar Would you please provide a link? I can't find information about hypster,TKS. I don't know where you can get it or if it is DIY only. but you can probably find one on reverb, ebay, muffwiggler, wigglehunt, modulargrid if you wait long enough. https://www.nonlinearcircuits.com/module...

no I don't think it would be pointless but if those are the only 3 modules in the rack then yeah kinda pointless without a VCO, VCA, VCF. The maths does voltage controlled slew. it has a mixer. it has comparators. it has min max. I'm pretty sure you can mimic the DUSG where it refuses to retrigger u...

the most common way to make wind is to start with white noise and run through filters or EQ. I found another way to do it with 16 VC square LFO all detuned with the CV being attenuated different amounts. I made an XOR chain so that the bit flipping was a function of all 16 LFO's. then I send a sing...
