Zynthian and Yoshimi

I recently decided to purchase a Zynthian device, which is a Raspberry Pi based hardware device which hosts Linux plugins to produce or process sound. You can for instance run a synthesizer on it like ZynAddSubFX (which I believe is where they got their name "Zynthian", although I'm not sure about that), and play it using a connected keyboard. Or piano. Or organ. Or any other of a load of plugins…
