Yes. Their ears and rails are great but I would save myself the eventual frustration and skip the stock TipTop uZeus power setup.

I’ve been thinking about getting a Trinity. Would you recommend? Any particular fun patch ideas?

Well it’s really nice to be able to reach for some LFOs and I find it really hands on and clear to use after an hour or two. The select output has proven really useful for on the fly changes or quickly testing different modulation styles. The clock sync on the main module goes a long way - I haven’t ended up using the expander resets that much but nice to have (I barely use up all inputs tbh but outs tend to stay busy). It’s may not be the smoothest sounding thing but that hasn’t had me worried. There is a mod for adding anti aliasing to all the outs. It will only do +/-5V out (switchable to +/-10V in). It’s just a good modulation source with a recorder function which lends itself to a nice feeling of painting in CV.

having just built my first rack (https://www.modulargrid.net/e/racks/view/598895) I feel like that video was a holy shit! moment of two things: using VCAs to control CV signals and using audio signals as CV signals. It’s obvious when you think about it, but it’s a part of the learning curve. So, yeah, thanks

This is great, thanks! Part of what I like about Bastl modules is that they’re a bit rough around the edges sonically :slight_smile:

I know a few people have this sort of issue. I can’t find the quotation, but I remembered watching a film where Tony Rolando (who runs Make Noise) was talking about answering somebody’s question; they asked him what in their rack would function as an X, possibly something simple like a clock, and he said “well, you have a Maths” and they replied

oh, I don’t want to waste Maths on that

at which point he pulls a face/shrug because:

there is no wasting modules.

There are a few reasons the ‘wasting modules’ idea comes around, and they’re all things you need to gently disabuse yourselves of. Reasons include (using Maths as an example):

  • I feel like I should know more; surely I shouldn’t be using module X for Y? Answer: no, if the module does a thing, and the patch needs a thing, why not use it for that thing?
  • It seems a waste of HP/$$$ for a simple feature: again, think musically - does the patch need it? Sometimes we wonder if we could be using our expensive/large modules for more but if that’s the role you need fulfilled in the patch, what’s the problem? We also play simple riffs on expensive guitars, plain melodies on expensive violins. Sometimes, Maths is a clock.
  • It can do so much more!: yes, it can. But not every patch involving Maths needs to be some brilliantly baroque self-patching marvel. Sometimes it’s a pair of envelopes, sometimes it’s LFOs, sometimes it’s a clock. If you’re only ever using it for basic tasks, maybe there’s a reason - you don’t need its features, or you don’t fully grok them - but that’s not to say you shouldn’t ever use it for those things
  • you don’t need to use everything in every patch: when we start out, we often have very small racks so we need to use all our modules in a patch just to make a sound, or do something musically interesting. As our racks grow, we sometimes keep up that patching habit - just patch until you run out of cables or inputs and outputs. Again - it feels like ‘wasting’ a module if you don’t use it in a patch. But not every patch needs everything; you don’t put every spice in the cupboard in a dish all the time, there’s no variance! But I think because the necessity to patch everything is high in small systems, it’s a harder thing to train ourselves out of in larger ones.

One thing I do find myself doing is using module X for function Y - for instance, using Rampage as a simple LFO - just because it’s what I thought of first, what my hands wanted to do. If I later find I need Rampage for a specific task, and I have something else that could be an LFO, I’ll sometimes swap it out to free it up - sometimes, we reach for things we’re happiest with, just like when I use the same turnaround or riff in a piano solo. But there’s nothing to stop you rearchitecting as you patch - for instance, when I realise I need something to be clock-synced, and I move my cycling modulation from Rampage to Tides to achieve that.

But really, if it sounds like you want, then you have patched it right. If that means you’re using an expensive and wide module to do a simple thing, who cares? You shouldn’t!

Anyone know how many HP a eurorack moule would be if turned on its side? I’m going to build a noise module into my 1U section.

Module panels are 128.5mm tall and usually PCBs are <110mm if memory serves, and each HP is 5.08mm.

110 ÷ 5.08 = about 22HP

i just held a couple unused module up to my case of racked modules and got roughly 25hp

Appreciate you putting this stuff into words!

Good point, hadn’t really thought about it like this, but I have had to go through this process.

Along the same lines, it sometimes feels like the longer I build patches, the more the experimentation and weirdness of the patching I’m doing has gone down. If I think back to when I did not know as much as I do currently and my system consisted of just an elements, peaks, 2-channel vca/mixer and an sq-1, I was doing some pretty crazy stuff (for example, turning the SQ-1 to Hz/V instead of 1 v/oct and turning Elements into a scary noise machine - https://soundcloud.com/midcentury/eoo).

That being said, if I listen back to recordings, I feel like compositionally my stuff has gotten a lot more interesting and have started to find my “voice” more since then (more recent thing - https://midcenturymodular.bandcamp.com/track/arp-of-the-spectrum-i definitely still pretty minimal, I’m still evolving there).

Yeah, correct - once you knock off 11mm either end for the ears, you get down to something more like 22HP.

Note that your board really must be 4HP or less if you want to mount it sideways: the gap between 1U rails is tight - max PCB height ends up being about 28mm for Pulp 1U, and about 22mm for Intellijel if I remember correctly.

Thanks all. I’m waiting on getting the PCB through then use a blank panel to mount it sideways.

Fwiw the module in question is the GMSN! Pure Noise. https://gmsn.co.uk/products/gmsn-pure-noise
Looking at the pics it looks like I can reduce the size of I mount it behind a 1U panel.

Can confirm 22HP. Converted a Radio Music to 1U a while back and it turned out that size.

Anything you would recommend instead? I just ordered a Tip Top Happy Ending Kit to get started hooking up some modules, but if I should upgrade the power supply out of the gate I’m interested to hear it.

If you already bought it and don’t plan on returning it may as well use it! As I expanded things got more and more unrecordably noisy but not right off the bat, YMMV. Some modules can introduce noise to the system, etc., which better power distribution can help mitigate.

A busboard that’s not functionally the equivalent of a flying busboard on a PCB – e.g. something with a ‘star’ distro design, etc. and a linear PSU seems to be a decent path. I still get more noise out of some modules than I’d like but things are much, much better.

Any discussion of power on MW seems to turn into a tire-fire pretty quickly; definitely a subject that stirs up outsized opinions :upside_down_face:

Personally, I’m using two uZeus with 12U of modules and have had zero problems: I wouldn’t worry about until you run into an actual problem.

I’ll echo what @LSA said. I started off with a 4ms row power with flying bus cables. Worked fine for a year and a half. But there was lots of bleed and a high noise floor. It eventually introduced a high pitch whine into my signal and decided I’d had enough. I just upgraded to two intellijel tps80s which are star rated distros. It’s a night and day difference.

Just a note, since I’ve seen some people confused by the terminology. “Star” when discussing power supplies for modular (and in some other contexts too) is a reference to the physical design and layout of the board, not a rating of quality or something. Star topologies put the central ground physically near the middle of the board, and directly run each output’s ground line to that central point. “Flying busses” link the furthest module’s ground through the next furthest, and so forth until you reach the main ground point on the PSU. The difference is that in a “star” grounding system, high currents and ground noise affect the other modules less, since they are not in a chain on the same wire.

Now, if your modules are well behaved and don’t draw a lot of current, a flying bus can be just fine. Or, if you pay attention to the current draw and put your higher current modules on the side closest to the PSU connection, you can also mitigate this problem to a large degree. But for situations where certain modules are particularly noisy or everything pulls a reasonable amount of power (e.g. more than a few tens of milliwatts) then you may gain by using a star topology. You might also gain by using a separate PSU for the very noisy modules, if you’re really in love with them and want them to calm down a bit. In that case the flying buses might still be just fine for the other modules. YMMV.

Thanks for explaining. Again, it’s made quite a noticeable difference in my 12U system. Lots of Make Noise, a White Whale, Intellijel, WMD, I.M., etc,

Thanks for the input! I’m approaching modular with the idea to not prematurely optimize too much, so I’ll keep this all in mind as time passes. :slight_smile:
