Yamaha DX7.
Oh you mean… OK. The one on my 2008 unibody MacBook, which I likely put the most hours in on of any of them. Then the one on my ancient and lovely Thinkpad T240 — one of the most pragmatically delightful computers ever — and probably the N33SX I owned in 1992.
The keyboard on the M1 Max MBP is quite nice, too.
DX7 had a dreadful keybed. Midi CC only up to 100 (instead of 127), wtf?!
Fatar learned a lot of lessons from Yamaha in that regard.
Looking forward to adding an Expressive E Osmose to my rig soon ..
OMG thank you - as a musician, that's the first thing I think of when I see "favorite keyboard."
