midi extensions: #6 TRS midi Type A on master module, would be great if there could be a dip switch on the back, to switch between type A and B. ... given the MMA has now adopted A as the standard, seems this is the future - but retaining backwards compatibly for arturia/novation support seems useful.
Just checking. I lost a whole day last weekend trying to get my Circuit (Type B) and my OP-Z (Type A) to communicate through a single TRS cable, when it turns out that the online resource I was using had a glitch in their data. I’d really like to avoid blowing another day off on such a bughunt if at all possible.
(P.S. this is a spec that really should be mentioned on the Wiki page for the Master module, IMNSHO. Not sure who’s maintaining that, though....)
-me-It's TRS MIDI B. There is a thread here: forum.aemodular.com/thread/265/midi-3-5-mm-adapter |

Did we already mention a (dual) comparator with CV-controllable threshold? I’d also like a dual Track & Hold next to the already available dual Sample & Hold. So basically more cheap and simple bread and butter tools  |

I know Robert's had a comparator module on his mind for a hot minute; I can recall discussing these with him waaaaay back, and now that we have the various sequencers and timing widgetry, these could be really useful in the wider scheme of AE things.
What I'm holding out for, though: window comparator. Way more useful and fun. Basically, you have an upper and lower limit, and these still act like plain old comparators so that when you cross the limits, you get a trigger pulse. BUT...with a window comparator, you can also set up the "window" between the limits to output a control signal (gates are the best for this) when the voltage is between them...among other bits of total voodoo.
I actually have a set of comparators that aren't synth gear...Frederick Haer & Co. is a manufacturer of biomed equipment, mainly for neurological research. And they make some things that, tbh, are VERY suited for synth work; in this case, I have two different items of theirs, both comparators. One of these, the Amplitude Analyzer, is just a basic window comparator with a few extra kinks. But the other...ahhh, that's the 4x Slope/Height unit, with FOUR dual window comparators that have a lot of extra functions, all connected through a MUX if desired. Even more fun is the fact that, according to FHC's techs, it outputs +5v pulse/gates via its load of different pinpatch points. Granted, you have to run the unit at its very lowest input levels (it IS for brainwave pickup, after all) for synth-level voltages, but that's its sole drawback.

Thank you, spacedog !!!
I actually thought I'd seen a thread somewhere mentioning this, but the search tool here leaves something to be desired and nothing came up when I tried to find it previously. Now that I know it's definitely a Type B, I'll test using my Circuit. Probably will be simpler than getting my OP-Z involved anyway. 
Much obliged for the pointer!

-me- I've become reasonably adept at using the search engine - the trick is to use either with at least one of the words or with all the words and then just ignore evrything else. There is so much information here now it can take a while even to work out what you're searching for (the real problem, IMO), admiitedly I had the advantage there as I'd written the post
Having wasted way too much time working out things like which TRS configuration is which (note there is a handy table linked in my original post), I just use whatever adaptor is supplied with the equipment and join them with a 5-pin DIN lead. It just works, even though it's not elegant. Although, having said that, the one supplied with the AE Modular is a bit flimsy and mine comes apart all of the time.
Now... I keep meaning to make a TRS A to TRS B lead (or even a simple in-line converter), then I'm just covered. There are only three connections and one of them is Ground (the sleeve), so all you do is swap the other two (tip and ring). You then just have to mark up which end is which - and know what each piece of equipment uses which.
Here's how I see it.
TRS MIDI Type A: MIDI Pin 5 (Current Sink) - Tip
MIDI Pin 4 (Current Source) - Ring
MIDI Pin 2 (Shield) - Sleeve
TRS MIDI Type B: MIDI Pin 5 (Current Sink) – Ring
MIDI Pin 4 (Current Source) – Tip
MIDI Pin 2 (Shield) – Sleeve
Someone correct me if I've oversimplified what seems to be a confounding issue.

Thinking about this, you don't even need to know which end is which because it's just a transposition of two connections. Is it really that simple, or am I missing something here...? |

I think a fader potentiometer module hasn't been mentioned yet. So simply one or two vertical faders on one module, acting either as static CV source (via a +5V input) or attenuator. Bonus points for several buffered outputs on the module |

What about some passive modules of 1U with a special case that could be put in between 2 case. A bit like the middle raw of a shared system from Make noise Shared system. But the twist would be that this "in between" 1U case would have the connection for the buss and be at an angle so the system would look (proportion aside) like a Three tier rack. This could serve as the support for the top case. Could have some 1U full mult, passive mixer, maybe tone or passive distortion or whatever works while been passive. |

in eurorack, I’ve recently become a fan of Ladik (ladik.eu)
They have a huge number of simple (and cheap) but really useful utility modules - pop to their website for inspiration.
just one example is the uncertain lfo (4hp,£55!) basically a wavetable lfo but with an element of randomness in things like amplitude.
Really clever as it gives you moving modulation but that’s not repetitive, something you would usually need multiple lfos/sample hold and VCAs to achieve.
As I say just one example, or a module that is pretty simple , but very musical.

Ladik are awesome - they delivered really quickly and even a free gift But yeah the range is excellent, obviously driven by someone who uses modular , and thinks ‘ oh I need .... ‘ and then makes it |

It is good we have the master with a Midi-in socket and I know there are now even 3 master versions (old with midi / new with midi and the new without midi), but I woul d like a version without midi, but with CV control.
So the Pitch / Gate / Mod, and a Sync In. (all 3,5 inch jack sockets).
A multiple for all (also 3,5 Inch jack sockets) would be nice, to connect other cases/synths/modulars. and 2 in/outs like available on de 4IO module.
I choose the 4 in sockets because of (for example) the Keystep and beatstep from arturia use this set of CV signals.
The clock and pitch and gate can be converted to the bus.
maybe 2 buttons could be used so start and stop could be entered manual.

Ladik is one of the more interesting...and cost-effective...Eurorack builders. But what I find interesting about them is that their prices give a bit of a lie as to what other Eurorack modules _should cost._ Take their skipper module, for example...two channels of probabilistic clock skipping for $72. And this seems sort of "eh" until you start digging and find that the next closest thing costs about twice as much! |

i would like to see a fatter filter. ARP, MOOG or something along those lines with some nice overdrive/saturation at high gain.

Now that Behringer have unveiled their plan for World synth domination, that will be interesting. As I implied elsewhere, I am all about getting the sound, which may mean more than one system working together. This is an example where I will definitely take an AE version, if available. |

Hmmm...JUST a filter? Strikes me that we could also use some sort of phaser in there, too. Intellijel makes something like this: the Polaris. Something like that would be a beneficial addition...a punchy, beefy, 4-pole LPF thing with massive Q AND the all-pass capabilities to allow it to function as a phaser. You could even drop an inductor in there to use as a saturation device to whump up that sound.

A bit back in the thread, there was a mention of a fader module. Over on MG, there's a new DIY one from ST Modular that has an interesting feature: simultaneous + and - offset outputs. So, not only would this be useful for levels by sending the + offset to a VCA's control input, you could use two VCAs and make this fader into a panner by using both polarity outputs and splitting the audio to two VCAs, then controlling those in opposition with the bipolar offset outputs. And so on...seems like a solid approach, to me...

A theremin module would be a lot of fun !
Also, an update to the VCA with one more pot per VCA : the offset, i.e how much of the signal passes through the VCA when no CV is applied. And speaking of offset, a proper attenuator/attenuverter/offset module is sorely lacking, especially considering the lack of negative voltage in Æ.

Not sure if this is possible but is polyphonic midi information transmitted through the bus even though the output is mono?
If so, a polyphonic module which allowed you to take 3 or 4 separate CV outputs of the notes in a midi chord and send them each to separate oscillator.

If so, a polyphonic module which allowed you to take 3 or 4 separate CV outputs of the notes in a midi chord and send them each to separate oscillator. Two ideas for this: First, a polyphonic MIDI-CV module (but this will not work via the bus CV) which will very likely in the future Second, an analog shift register module, that takes one incoming CV and four outputs, and via a trigger signal the four outputs are shifted by one, the last falling out and the current CV at input is stored. So with a fast "filling" this could be used for polyphony. Lugia gave me the inspiration this would be a cool thing, and I agree :-) |

I think a fun module would be a stereo recorder. Only have two audio signal inputs with two buttons: Start and Stop. Then also have a micro-SD card slot so you can take memory in and out.
This would then make a system really portable and self contained. I'd be happy with a simple 44.1 kHz sampling rate at 16 bit depth if possible.
If you make it so that the start can be triggered externally you can link multiple stereo recorder modules together to create multitrack recording....

Yeah, I still like the Analog Shift Register idea. Not only can you use it for chordal polyphony, it would also give you the basic backbone for an arpeggiator. Pluuuuuus...an ASR can be used for all sorts of CV store-and-forward behavior, not simply pitch changes.
