Warpjam mentioned to me that Gizmodo pointed to the Topaz-1, an old Soviet electronic accordion, pictured below. I love the styling, which is reminiscent of the original Star Trek series’ design aesthetic:
Here in North America, electronic accordions have been marketed by
Iorio (sometimes under the name Elkavox). Here’s a top-of-the-line

There are also MIDI (Musical Instrument Digital Interface) accordions,
which can be used to control one or more synthesizers, samplers and
even drum machines Here’s the ultra-fancy Excelsior MIDI accordion:
And let’s not forget the premier make of accordion, Hohner, who haven’t forgotten that we’re living the 21st century now.
