Yamaha QX3 sequencer
So you're saying hey Ivan... this isn't a keyboard why are you posting some music kit in here? Well because this bad boy has Cherry Hirose MX orange switches and double/triple/quad shot keycaps. Check it out.
While I would love to get this I just can't afford it at the moment even at the $125 starting price.

Interesting find & switches. But it appears that Hirose Oranges are a little bit stubbier/fatter and smaller than regular cherry MX switches.

Quick Google translate says they're 60-70g actuation/bottom out, similar to MX Black.

Ivan, do you know whether those caps are made by Cherry or not? I'm very interested.

My best guess is those keys were probably made somewhere in Japan if not by Hirose. They are quite distinctly different from any other MX keycap I have seen on anything else. No they are not stem compatible with common MX keycap, the stem mount is smaller but the housings and electrical pins etc are cross compatible.

In case anyone here does get this with the intent of harvesting the Hirose switches and keycaps... if you feel like dumping the rest of the sequencer at a bargain price you know who to offer it. :))

One of the few tripleshots available, and one of the even rarer quad shots. I think the only other quad I know of is a keytronic mount.

I'm not as familiar with hirose. Can you desolder and replace with cherry MX? I think they are pin-compatible.

I mean, If I were in the market for bargain sequencers, I'd desolder and replace with relegendables on cherry black.

Right, besides from the smaller keycap stem ¯\_(ツ)_/¯ they are the same as MX in very other way. Hirose was simply the Japanese licensee of MX back in the 80's.

Huh, those caps look to be the same shot technique as those triple shot Topre compatible caps that come from Brother (I think) typewriters.

The Brother AX series typewriter keycaps are pretty awesome

(thanks to terrpn for the picture)

But the bottom looks completely different than the hirose. I just think they're the same age, not necessarily the same factory

Yamaha sequencer keycaps appear to be cherry profile but (possibly) shorter.
