Recently I've been thinking about deconstructing a ThinkPad and putting the internals inside a MIDI controller. We're at the stage where VSTs/DAWs easily sound better than any synthesizer with internal sounds. But, it's a huge pain to carry a laptop and a sound card to a gig. When will someone address this?
I’ve actually been building a few synths based on the Pi over the years—it’s been a great way to “get rid” of the older boards as time goes on, although since I’ve never bought a Pi 5 I suspect that time has past.
You can use the Pi 2/3/3a/Zero 2 to build things like an mt32 or DX7 emulator almost trivially, and they make for great DAWless modules.
I wrote a software synth myself with the intention of running it on Raspbery Pi 3 / Zero 2. Those are actually quite capable processers; sound synthesis requires very little RAM, both code and for maintaining state, so everything fits in the rather tiny cache. But at the same time, while these Pis use "little" cores, the maximum throughput of NEON instructions is actually the same as for the corresponding "big" cores like the Cortex-A72. With four cores, you can do in the order of ~10 GFLOPS 32-bit FMA instructions. With a sample rate of 96 kHz and 32-note polyphony, you theoretically have a few thousand FMA instructions per note to spend.
Max MSP has RNBO [0] which provides a Pi image, and a quick deploy path for patches. I've used it for a few art installations, and the versions from this year have been super nice. Basically, you can design and test audio on your regular dev machine and quickly deploy to the PI. You don't need to mess with any Linux audio nonsense.
Little bit shallow article. Raspberry 3/4/5 are in a different league than RP2040. Newest Zynthian kits are updated for Pi5. There is also a big difference between using Linux (e.g. Zynthian) and running barebones (e.g. Minidexed, MT32-pi, probably some proprietary offerings).
I discovered by pure chance the vast ecosystem of iOS synths apps. And I was absolutely blown away. 90+% of the synths of the past century are available for ~5-20€ each. Connect that to a basic KORG MicroKeys Air [extra cheap, but includes Bluetooth]. And you are the next Jean-Michel Jarre.
[Note: and the amount of tutorial videos on YouTube is huge.]
For some synths like Blofeld, you're paying $10-20 for something that used to sell in a box for $300. And it's the exact same synth (100% digital) often with a better UI.
The iPad is a great choice for music - you get the variety of hardware synths with none of the annoying setup (power, midi, audio routing), at a cheaper price, but it still feels more immersive than sitting at a desktop PC and a daw.
But they are not the same, if you are a musician going to bars and practice spaces and the like that $300 Blofeld will handle the abuse and accidents much better than a laptop or tablet. No matter what you do and how careful you are, cords get snagged and stepped on, stuff gets knocked over, things get spilled etc etc etc. My Blofeld has taken far more abuse than any laptop or tablet will handle and still going strong 15 years later; three laptops and two tablets later.
There are things you can do to make computers more suitable for this stuff but it gets expensive fast and less convenient quickly. Toughbooks are tempting, but expensive, rackmount computer can be managed for not much and keeps the computer safe in its rack but now you more and bigger stuff to haul. Taking a disposable approach with rpi or the like is tempting but not exactly ideal. Computers/tablets are great and have their uses but are not a replacement for hardware yet.
The big problem for me with all things touch screen is that they get confused by water on the screen, which is an issue when it is hot and you are sweating or on a stage with bright lights cooking you. Not an issue if you just want to tap out beats but a serious headache if you want to adjust parameters. Connectors on tablets are also an issue, USB is not a very secure connection and the wireless options are not great. Give me a tablet with a plastic screen, 1/4" ins/outs, can run PureData and will not get confused by water on the screen and I will probably give up my hardware.

On the other hand, my Blofeld had wonky unresponsive knobs after just a couple of months, not that they were very good at the first place, who thought having knobs with no tactile feeling of grip was good idea?!
Personally the biggest win for actual hardware is that it's just more fun to play and use. I've tried various music apps for mobile/tablets and while it's fun for some minutes, that's pretty much it. But then I feel the same with DAWs, it's just not as fun as playing with an hardware drum machine + synth + sampler all hooked together.
GarageBand is free on every iPhone and has a good selection of starter synths, with added DAW capabilities. Bluetooth midi controllers are supported (via bluetooth midi connect App). Using a pi or Arduino to build a midi controller can also be great fun.
> Conversely, the likelihood of making it big just by making some good damn music was never lower than it is now.
Is that statement backed by any facts? Otherwise it sounds like a soundbite that sounds good, but I'm not sure how true it is. Maybe what "making it big" has changed more compared to how many people make their living making music, which for me would be enough to be considered "making it big".
Yes! But, huge but, very huge but, you lose the affordance of the switches and the buttons and the knobs and the patch cables. And that is a terrible loss for fiddling and discovery.
True. But for going from zero to semi-hero, that’s definitely an option.
[the huge amount of presets in software synths is really an BIG added value, so you can learn how each given sound is built]
When the word synthesizer is used, it's not meant to be a piano like thing or? For me the word is analogous to "piano keyboard" but it seems to not be so...
A synth is a device that generates sounds. They’re often (but not always!) controlled by piano-style keyboards, but so are lots of non-synth things. For example, although a piano emulator could be a synth, they’re generally not thought of that way. A sampling keyboard is not a synth: it’s playing back recorded sounds.
Lots of synths spent their whole lives never connected to a keyboard, but might live in rack mounts and be driven by sequencers or DAWs.
For some time now I've been supplying all my audio DSP plugins at airwindows.com pre-compiled on the Pi 400. (MIT open source, so it's not limited to that). The Pi version is included.
I mention this to make a point: you can't transform synths just by running some generic DSP code on a Pi and putting it in a box. Sound processing is also being transformed, and whether it's something like Hydrasynth generating poly aftertouch (but aliasing and not sounding that different from a VST) or Novation Peak/Summit receiving poly aftertouch (not generating :D ) but generating sound using custom hardware, sitting a VST on a Pi isn't going to get you a transformative synth.
Thing is, if you're able to dig into stuff like my DSP codebase that is actively under development AND plunk a VST synth onto a Pi AND do something interesting with the physical controls to direct the synth engine, that's starting to look transformative again. But just knowing about Pi isn't enough, you'll have to have a deep background in soundmaking and the ability to instrument-make in an interesting way.
If you have those things… game on. You can begin work FAR more cheaply than ever before, and that is how the Pi could be transforming synths.
I'm waiting for 24/96 audio hats to be common before I dig into this, even for stompboxes. I'm given to understand Electrosmith Daisy already has this, and that's a similar class of 'system on tiny board' that should be considered an audio Pi-like.
The m8 and the recently, heavily promoted Woovebox 2 are the Emacs/Vim of grooveboxes. They hide a vast amount of functionality behind what initially seems like an impenetrable jungle of button presses and shortcuts; a system that ultimately proves* to be highly ergonomic.
*Based on what I read. Sadly, I don't own these devices.
Typical how they first let Korg do the talking, when actually, Korg is much slower to innovate. With one line, the article mentions Tasty Chips synthesizers (who are friends of mine), but as far as I know, they were actually the first, just check their Kickstarter campaigns which go back ten years.
Note that using RPi is not all sunshine and roses. There were times that compute modules were extremely hard to get.
Arturia does that, and Korg did as well (making controller keyboards specific for emulating a synth, with the software running on a Mac or PC.
Downsides:
- if the software doesn’t get updated, you’re stuck running an old OS an old Mac that supports it.
- you can’t just turn on the synth and use it, you need to find a cable, connect it to the Mac, launch the software, etc
What I don't quite get is why manufacturers of midi controllers (Arturia, Novation, NI, etc.), with the exception of, possibly only Korg, don't release any of their digital instruments as mobile apps. After sitting the whole day in front of my computer, the last thing I want to do is to swap VS Code for Ableton or Kontakt and spend a few more hours in the glow of my monitors.
(I do get that if you are very serious about making music you need a proper computer set up. I am just a mere amateur hobbyist.)
You can use the Pi 2/3/3a/Zero 2 to build things like an mt32 or DX7 emulator almost trivially, and they make for great DAWless modules.
People also use this to make unique pedals.

Conversely, the likelihood of making it big just by making some good damn music was never lower than it is now. Makes for a fine hobby though.

Now that I understand most of it, I am really considering buying a ARP 2600 replica.
So yes, the switch from software to hardware comes with time. But, at least for me, the first step is cheap apps on my already-owned tablet.
And something like VCVRack is heaven to learn, experiment and understand what one can do with synthesis, step by step.
