Nik's Meta Module Explorations

TL/DR: Nik warbles on about his history with VCV, much of which you will have read before down the years, as a prelude to a series (hopefully) of posts about the Meta Module.

As most of you know, I began my journey into modular a week after the first VCV beta release back in August 2017 (though I had dabbled with another company’s software, modular VST, released slightly earlier). In 2020, I took the plunge into hardware, developing a Eurocrack addiction and an even worse one for soldering modules together. There are only so many hours in the day, though, and I no longer spend any of them using VSTs in a DAW (only occasionally hosted in VCV).

I still explore patch ideas in bed in VCV sometimes, and that has been greatly enabled by my decision to buy as many Mutable modules as I could before Emilie shut up shop and by building a large collection of Befacos. I rarely build patch ideas in VCV that I cannot build in my hardware. The joy of the Meta Module is that the modules available in the patches I can now build have increased by about 600 so far.

I’ve mentioned many times on here that I began my hardware journey with an ES-9 but immediately found that a hybrid setup wasn’t for me. Half of that was latency, and half of that was I found that when using hardware, I didn’t want to see a computer or iPad screen in my field of view (and preferably not in the same room). I still print out modular manuals. Pretty old school, really.

The Meta Module is like ‘coming home’ for me, and I’ve been excited about it since it was announced. It’s great to get back into using VCV in anger and get access to some great modules that can’t be found in hardware.

I’ll report back a little on how I find using the module, some of the uses and patches I make for it, and some audio in the future; apart from recording samples and loops into modules, I almost never record any full patches I make. I patch from scratch, mainly in a rather haphazard and exploratory manner, until I find ‘the sound’. Then, I build a patch around that sound. Even if I like the resulting patch, I almost never record it (maybe once every three months). Patches generally live no longer than a day because I almost never patch with a goal in mind, other than to explore a particular module or combination of modules.

I will seriously endeavour, though, to record some stuff with the Meta Module and share it. Please remember that I have never claimed to be a ‘musician’, just somebody who enjoys exploring sound. Most of the patches I make are soundscapes, textures or drones, often rather noisy and heavily distorted ones. I can sit tweaking knobs on a patch like this for hours on end, exploring all the nuances of the sound, but as a recording, it’s not great to listen to. Some people record all their patching and noodling so that they can pull stuff out of it later on the computer, but I have no desire whatsoever to spend my time doing that.

I’ll do my best to find something something interesting to share about using the Meta Module with you. I’ll also stick some patches on PatchStorage when they create the category.

So, to first impressions and experience of the module itself. [NB There may be misunderstandings in what follows - feel free to correct me.]

Aesthetically fairly pleasing for me. The brushed metal looks lovely. My only complaint about the physical aspects is the tall trimmers. I hate tall trimmers; just make the module bigger, please - Eurorack is cramped enough as it is. Here, though, they are doubly egregious because they are the main controls. There is no difference in function or use to the six (A-F) with Davies knobs. [There is actually a lower level of hell waiting for those who put short trimmers on modules.] As you can see, I have put Thonk Tall Trimmer Toppers on them, but I would rather 4ms had used metal shafted pots where I’d have a wide choice of knob replacements (the VnIcursal to the right suffers the same affliction, though on his other kits, he has metal shafts and I’ve been able to put Bastl knobs on instead).

In the box was a new 16 GB Micro SD card and a short USB-A to USB-C converter. Weirdly the SD card had problems last night, which is the first time that has ever happened to me in all the years I’ve been using them. My MBP will read and write to it, but Meta Module either reports that there are no modules on the card or says that it can’t read the card at all. Anyway, I used another and all is fine again.

I made two patches in my 7U, using the module without patching in VCV first as a Disting on steroids. It is really very easy and intuitive to do this. The only gotcha is that you have to load up the modules (plugins, rather) you want every time the module is powered up. This is simple but tedious.

Pulling up a module and automapping it is very easy, though the automapping proceeds based on the first available jack/knob and may not produce an appealing or intuitive map. I intend to create a series of patches for my favourite modules with mappings how I want them. Remapping in Meta Module, or mapping from scratch, is easy but tedious for many connections, involving multiple encoder presses for each one. Much of the time, though, it is a case of why bother? It is great to enjoy the flexibility of pulling up a module for a specific use, automapping it, and it’s up and running in seconds.

Connecting modules in the Meta Module requires more clicking and scrolling but is reasonably quick. You really don’t want to build patches in the Meta Module with more than two or three modules connected together. It’s a bit of a chore. With both my patches though, I had two modules connected together and then additional discrete modules loaded as modulation sources. I imagine 90% of my use of the module will be just like this, and I wouldn’t reach for the computer to facilitate it.

Considering the best strategy to map knobs is another thing entirely. You have multiple knob sets, but a control can only be mapped to a knob once. This is a pain and hopefully can be fixed in a future update. As it is, you have to choose between a knob set per module or trying to get all the main controls for all the modules, patched or not, on one page (or some hybrid). I’d rather be able to do both, having the master knob set controls also available from the module-specific knob set.

EDIT: A fix is in progress for this - v. #4 in thread.

Last night, I tried two more things. The first was to transfer some patches I had made to try them out. This didn’t work well. I had thought I could get away with keeping all the patches, discrete as they are, in one VCV patch, but the presence of multiple virtual Meta Modules in a patch appears to confuse the saving process, and when the patches loaded into Meta Module they were messed up with each appearing contained all the modules that were attached to each of the five Meta Modules in my VCV patch. So, the rule appears to be one per VCV patch.

The process of saving to an SD card each time you tweak a patch in VCV, transferring it to Meta Module, and loading it up tests one’s patience somewhat. I predict the first expander due out, the Wi-Fi one, will sell very well. It can’t arrive soon enough, as far as I’m concerned.

The other thing I wanted to try out was the Midi implementation, which I discovered was the steepest section of the learning curve. In hardware I use an FH-2 to work the Disting Ex, and to attach a Launchpad Mini as a step sequencer occasionally, or to use the Buchla Thunder Sensel MPE overlay. The stupendously powerful yet a little boggling Vector Wave I built has a Midi input to control its 4 voices and 16 oscillators, and I occasionally plug a keyboard into that.

Of course, this would be an exponentially more wonderful experience if I could actually play a keyboard. That boat having sailed and no longer doing anything in a DAW means that I almost never use Midi in software, which leads to saying that I am incredibly rusty on using the Midi modules in VCV. I experimented with them when they were released but ignored them since.

All that made figuring out how to use Midi with the Meta Module and VCV an evening of trial and error, but I got there in the end. The Meta Module is somewhat confusing because when you build a VCV patch, you use the VCV Midi modules (IN only until the release of the Midi/gate expander), but when you upload the patch to the Meta Module, those VCV modules are invisible. Meta Module understands what you are doing in the patch but handles the Midi directly and invisibly. There is no Midi monitor to see what messages are coming in, and you can only disconnect a Midi connection, not make a new one (in the Meta Module itself). You can partially ameliorate some of the potential inconvenience by connecting Midi in/out to mults, giving you a connection/disconnection possibility.

Anyway, after a couple of days, I feel I have a fairly good handle on the module’s functionality. I’m extremely impressed with what 4ms has done here. It’s as usable as I think it is possible to make the concept. The whole scrolling parameters and jacks to patch is pretty much the best alternative to a touchscreen, which I doubt would work well.

It’s certainly not a place to learn VCV for newcomers, though. Its initial kerb appeal will be to experienced VCVers, I think. If you are already familiar with the modules you are patching, it makes a big difference to how quickly you can patch and allows you to make sense of the small renderings of the modules on screen.

The first serious journey I want to take is with the Hetrick phasors. I’ve not really used them yet, so there will be a learning curve with Mike’s tutorial and Omri’s record hour-and-a-half-long video on his Patreon.

I have another early journey I want to take to try to fix some undesirable behaviour of a valued hardware module with VCV. I’ve only been partially successful in taming it with other hardware modules thus far, but more of that anon.

Great to hear your backstory and journey Nik, which is not that different from mine. And thanks very much for the report from your exploration of Meta. Feels like a very authentic and relatable report from the trenches, which is exactly what I was hoping for. This should be useful to many, including 4ms. Keep ‘Em coming!

Thanks Lars.

Small update on the knob mapping issue. This appears to be a bug in the VCV Meta module, not the hardware Meta Module, where multiple knob mappings can be made manually.

I posted an FR on the Metamodule forum, and another user discovered that if you manually edit the yml file to put in the extra mappings you want, Meta Module reads it correctly,

EDIT: Dan has now posted that the bug is a regression after he made some other changes, and he’ll get a fix out early next week. A workaround is to always use different knobs.
