Slightly Disappointed with the MetaAIO

It works great! But I’ve come to the realization with respect to how I use the MM, I still don’t have enough inputs and I won’t be able to add any more. I use my MM with a large rig, so I have lots of hardware that I can feed into the MM. Even with the AIO I don’t have enough inputs for one of my favorite individual plug-ins, the version of MI Elements.

Instead of 6 inputs and 8 outputs on the AIO I would have liked the reverse (or in my dreams, the ability to designate on an individual jack basis whether it is an input or an output :grinning:). Perhaps I’m just a niche use case and the module as configured meets the needs of a majority of MM owners. With MIDI I can add plenty of additional controls, but I’m now at a hard stop with respect to inputs and outputs.

I would consider using MM modules for modulation sources. For example, with MI Elements, you could use instances of Tides or other modulators and then use the knobs to control them.

I have utilized many of the MM modulation sources in patches I’ve constructed. But… it’s far from being a similar workflow. I’m not a big fan of paging through knob sets on the MM when I can directly access the controls on an external module. There is also the immediacy of plugging in an external signal when experimenting vs having to stop and go menu diving to find and connect an internal plug-in.

I realize that many are very happy planning and building mega patches on the MM. I did that initially, but became bored with that workflow. My current use is to build a patch using only a couple of modules and integrate that into my larger rig.

Fair enough…the MM certainly has hardware and software limitations that you must work within. Perhaps the only solution that will fit your use case is to consider using multiple MMs and MetaAIOs if your budget can handle it. BTW, I noticed that Elements is one of the heaviest CPU modules in MM. I can only imagine how much CPU would be consumed by all of those external jacks!

At first, I also felt that the input was insufficient, until I got used to compensating for this issue by using saved presets.

What I mean is that under normal circumstances, your module won’t use all modulation input.I only modulate the input that the current sound needs.You can design an identical patch but save different presets for different modulation settings.

For example, I can set input 1 as my modulation source, but create two different presets to change the destination.

Reading files in the meta system is very fast, and I can use this method to design a large variety of different structures. By changing presets, I even realized that I no longer need AIO…But you need some time to get used to all of this…

Don’t forget nearly every control can be modulated via midi. try using a decent controller like a faderfox uc4.

To be fair, the module does what it was purported to do. I was thinking about indented knobs or knobs that can be actuated to give extra functionality but the expander is already out. Any expander with latch control? I would probably use MIDI to get more from MM itself. If we get all the related modules, soon we will need 64HP+

There’s a button expander coming at some point.

I said this at some point before but the expander I would most like to see would have a mixture of inputs, outputs, knobs, and buttons. I don’t need 8 buttons but I would love to have two.

I have several MIDI controllers with knobs and buttons that I map to controls and attenuverters in the MM. That works so well that I don’t know whether the knob and button expanders when available will be “instant-buys” for me like the the Wi-Fi and AIO modules. But wiggling a knob or a fader is not really sending a device or plug-in “modulation” in the classic sense. In my rig I’m using the MM audio/cv inputs for external audio, and for CV modulation from sources like my Batumi, QV-L, Maths, Pam’s, Tilt, multiple sequencers, various oscillators and envelope generators and other signal sources.

I agree that “the (AIO) module does what it was purported to do.” and my post is not intended to be critical of 4ms. I just wish there was an option for even more inputs. That is all. (I think some people missed the word “Slightly” in the Subject line).

As someone who both worked for over 30 years in PCB layout/design and personally designs things using microcontrollers for fun, the reality is that even with multiplexing there’s only so much you can physically connect and still maintain reasonable performance. Given the other announced expansion modules, my impression is that 4MS is getting very close to that limit when all is finally available. TBH, I’m amazed at the scope of what they’re doing with the entire system.

Yeah, they are giving that single STM32MP1 a real workout!

The co processor (Cortex M4-F) actually handles all the controls etc.

That is integrated on the same chip, right?

"The STM32MP157A/D devices also embed a Cortex® -M4 32-bit RISC core operating at up to 209 MHz frequency. Cortex-M4 core features a floating point unit (FPU) single precision which supports Arm® single-precision data-processing instructions and data types. The Cortex® -M4 supports a full set of DSP instructions and a memory protection unit (MPU) which enhances application security.

“The STM32MP157A/D devices also embed a 3D graphic processing unit (Vivante® - OpenGL® ES 2.0) running at up to 533 MHz, with performances up to 26 Mtriangle/s, 133 Mpixel/s.”

Oh, you’re probably right.
Crazy how much power they can pack into a tiny thing the size of your fingernail!

Yep…it is amazing! I used to do Tech Support for embedded and dev kits for a global electronics distributor. Learned and taught a lot about that technology back then. That is when ARM was really taking off after the launch of RasPi.

Apologies for partly repeating myself, I mentioned this in working Midi devices.

Befaco Voltage Controlled Midi Controller works well.

Gives you 8 faders, 8 buttons, 8 CV Gates and 10 CV Controls.

I hadn’t been using it much, but it’s been given a new lease of life pairing with the Meta Module.

All of the VCMC controls can be mapped separate or combined :slight_smile:
