Korg Kronos has multiple versions and iterations.
This is likely from Korg Kronos 2025 model.
Similarly Korg Grandstage X is from 2024.
So this plugin can serve similar function to Dexibel T2L VST plugin, ie. preview samples if you're interested in buying either GrandStage X or Kronos (2025).
GrandStage X is mostly notable because it uses 25.5 GB PCM wav rom, which is not bad at all for a slab retailing at 2.4k eur. (if I recall the main piano sample in the old GrandStage was 2.8gigs in size, which is very respectable).
Korg Kronos is notable because it internally uses intel x64 CPU (atom) with 120gb SSD (and a linux kernel with realtime extensions).
For context, sample size in Yamaha P515 is 512megs total wave rom split across main two piano samples and other sounds.
And sample size in say Kawai MP11 (not SE) is 256mb+64mb, so total of 320megs.
As usual, DPs that use respectable rom/flash size always proudly say it in their PR/spec sheets, and ones that don't - never mention it... (and you have to dig it up)
Another data point for context - 8gbit winbond nand flash (so 1 gigabyte) in a package commonly used in DPs (like P515), adds roughly 2-3 eur (if not significantly less) to BOM if bought in volume.
In a sample based DP (which most DPs on the market are), sample size is a good indication if it will sound atleast half-way decent until you reach a diminishing returns point (which is roughly 2-3gigs for a sample) where you have enough memory to fully record all keys with 8-12 layers or so.
Modern D has 5mic sets, and takes roughly 18gigs on disc (probably with some compression), so roughly 3.6gigs per micset.
