According to the video, the on-board PCM must be much more than the 400 MB somebody mentioned in another thread. So probably it was somehow mixed up with the 400 MB of user storage.
I assume they have raised the PCM waveROM to the Krome level just by implementing its German Grand piano and e-pianos, but let's see...
Although I'm not impressed by the video yet, I think it's appalling how some Youtube users are already starting a shitstorm about it without the details being clear.
Now it states 10 times more PCm ROM then PA3x. how much was in PA3x?
Kronos Pianos are about 4GB in size, so if any of those is in there, it might be huge.
But only 400 MB free? really? thats less then in PA3x..
Myabe they just put in an 8Gb MSata SSD instead of ROM and put as much samples on there as possible.. IF so, i hope you can upgrade it to create more sample room. If so, it suddenly opens up a lot of potential
