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.
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.]
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.
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.
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.
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.)
