I have at least five synthesizers built on RPi Compute Modules. Three of them are from a major manufacturer, Korg. The Korg Wavestate, OPSIX and Modwave are all running RPi CM4 and an optimized version of Puppy Linux to make them go. They are actually quite powerful and they really did impress me. The other two are smaller makers with one being open source so they are a little less a real world consumer product like the Korg synths. I expect more synthesizers use Raspberry Pi boards but I am not aware of any with proof except the Korg Multi/Poly which I don't own yet.
Sounds interesting and also allows them to update/fix issues if you run into them. It also would (possibly) replace a compute module if it failed.

Pretty much all modern synths allow for software update via USB, SD card or even a few with WiFi/Ethernet. Korg has released various fixes and feature updates over the last few years for these synths, but most manufacturers stop adding new things after a couple of years. As for replacing the compute module, some people have suggested that there may be some fuckery going on that prevents you dropping in a new CM and getting your synth working again. I wouldn't doubt that Korg has things "serial number" locked or something like that to prevent such an easy fix from being done.
Hummm, Sounds like something to point out to Louis Rossmann. If you bought it, you own it. You should be allowed to replace parts and if they are doing something like that it should be pointed out and reverse engineered.
