This is a standalone hardware sequencer, not some softsynth or DAW on an incremental release schedule. This also was not sold as an early access product which it clearly is. The level of bugs make it unfit for purpose if you had any intention of using it live.
The KSP was also meant to be played with a computer.
But ok, despite being myself a "full hardware" freak, I can face the fact that this gear is still partially "computer-ish" (it's a complexe electronical that is far beyond a simple analog synth), and even if we can always rage about the fact that it may have not been "stress tested" enough, no gear nowadays with this level of electronic -computer at its core- goes out without bugs... and updates !
You can check, even big ones like the lasts digital workstations, as the Roland Fantom 8, Korg Prologue, Minilogue XD, The Wavestate, my small but powerful Tasty Chips GR-1, even digital pedal effects can have frimware updates now.
I'm waiting for a Elta Music Solar 50, which may have no bugs and probably have not any update : it's a full analog.
I'm also waiting for the Osmose from ExpressiveE, and I bet, despite the experience and master level of dev from both ExpressiveE and Haken for the Eagan Matrix, it will have probable bugs and updates, and I'm ok with that ! (imagine how foolish I am, I even have peordered it long before it was even simply out of the prototype state)
And it's not new neither a secret at all, so blaming developpers after buying is either being really naive today, or kind of dishonest (and forcing the odds to jump into the blaming stance in a way).
PS : I never said I like to have new stuff full of bug, I only say that's very common and hard to ignore for years and years, and you have to always keep in mind that either you buy a gear in the exact state it is the moment you do so (and never count on any promise), or you make a bet about upgrades and hotfixes, but you can't really say that's a surprise if something is not that operational so early after the release.
