I eventually ended up with 4 LUMIs which you can snap together magnetically for a 96-key keyboard. I tried them for a few minutes and completely lost interest.

The action is terrible, not even on par with my KORG microKEY Air-37.

Thanks for sharing, I was indeed curious about the LUMI.

Let's wait for someone to confirm the resonance, but meanwhile here is a test we can do:

1) play one of those low notes with the screen keyboard, press the sostenuto pedal, release the note and wait for it to die down. Then play something.
2) release the sostenuto and play the same something, searching for differences compared to the first attemp
3) repeat as long as it's clear what is going on

I haven't tried this (yet)

Citation needed. Jokes aside, can you elaborate more on what is it?

I was in for 2 LUMI Keys by ROLI in the original Kickstarter. At the time, I was interested in a portable keyboard for practice while traveling. The campaign wasn't really well managed and production was sort of chaotic at the end.

Right, basically I want to enable resonance of these extra notes, same as on a Bösendorfer.

My understanding is yes, but I'm a mere newbie with it, so more authoritative answer needed.

AFAIK, there is no commercial more-than-88-key controller. However there is one (which I don't remember now, it was discussed on PW) that is modular and you can attach octaves to make it the size that you want (usually used to make it smaller, rather than larger, but IIRC can be made larger too).

From the acoustic point of view, there are several instruments with more than 88 keys, most famously a Bösendorfer. Here is a summary of many others:

Pianoteq already supports 105 keys on the piano. My interest is not in using those extra keys, but in configuring how many keys are currently enabled, even if they are not actively used. In particular, I would like to know if this impacts the resonance modeling.

Will the extra bass (or treble) notes resonate with the dampers lifted?

Pianoteq appears to support more than 88 keys on a piano -- up to 105?

How do I control the number of keys that are currently enabled on a model?

In theory shouldn't the number of keys currently enabled affect the resonance modelling?

And of course there is the DIY like Cybrid or things discussed on kvraudio
