DRIVE THAT WE INSTALL... HOW IS THIS SITUATION A
Speaking as an OS kernel developer: because the two situations have absolutely nothing to do with each other. It actually is a bit odd

When we looked at this during the Coyotos kernel development process, we concluded that we actually could handle up to 16G of physical memory within our kernel virtual space constraints (we only have 0.5GB of total KVA), but users who needed that much memory would be better advised to shift to a 64-bit platform. We therefore elected not to implement that.
I worked for an embedded systems software co for 3 years, and recall
Dan mentioned embedded system design in the Kronos.

If you are trying to understand Kronos system design, I think one
Has to be up to speed on embedded systems and embedded system
Software design.

Kronos is not comparable to a $600 pc with max ram, etc.

That's exactly right. Coyotos, by the way, is a high-confidence microkernel for embedded systems.

And the more I dig at those hardware photos, the more inclined I am to take him literally. And if Linux isn't driving the boat, then a bunch of things that struck me as strange about it make a lot more sense to me.

this may also be of interest, from: http://synth.me/music-gear/interview...ep-korg-kronos

"As with the OASYS, the main part of the KRONOS runs as a low-level realtime process within a customized installation of Linux. In practical terms, 'realtime' means that musical functions such as playing notes take precedence over normal OS activity. ... Linux provides basic system services such as the file system, USB, multitasking, memory management, etc."

No, I think you should be able to append Assault (into the spare User G bank, if you don't want to overwrite the factory presets) along side ALL of the EX's, and STILL have about 450Mb left over for your own samples.

Assault uses the following:

837Mb RAM

RAM Multisamples 132/1000
RAM Samples 2488/4000
RAM MS Indexes 2489/4000

Good eh?

Thanks Kronik, Yeah thats great news. Weird that Korg didnt put the extra RAM in at the get go. Money I guess...

Has anyone else installed this on their keyboard yet?

I'm psychic, and I am thinking you started working with a Coyotos pre-cursor back in 1990? Correct?

Yup. Coyotos productized around 2007.

So is there any way to do this without voiding the warranty? Can I buy some extra memory and have an Authorized Repair Center install it for me?

Not likely for a while... It's not an authorized repair or upgrade.

The useable space is less than its true capacity due to the file system structure, etc. A 2GB DDR2 memory module costs something like $25. Losing .75GB is not something to lose sleep over.

The usable hdd space is *equal* to the true capacity. Remember, storage media capacity is usually quoted by the OEM in metric, and by the OS in binary (using metric notation).

RAM is quoted in binary by both the OEM and the OS.

Although I don't condone this action, I've gone ahead and installed 4GB!

If you're going to do it, just take care.

All the screws on the base of the Kronos are the same size, which is handy. The only thing to be careful of is that the entire keybed chassis becomes loose when you take the bottom off. There's no internal security tabs or locktite on the screws.

I've kept the original 2GB RAM safe, in case I ever need to reinstall it!

I now have all the Factory EXs and Assault running with 287MB still free

Can we have the instructions of how to do this turned into a sticky?

I think it will be useful for many users.

Maybe the next person can YouTube it.

Awesome! However, I really don't understand why Korg didn't ship the instrument with 4MB already installed . . .

Cost.

It would be nice if they had made it more easily user-upgradable, though... i.s. an access panel instead of having to take the unit apart. Though I'm sure there would have been manufacturing cost associated with that as well.

Considering that it is relatively easy and inexpensive for an end-user to add that memory anyway, if I were going to add one bit of hardware enhancement to the design, rather than put in more memory by default, I wish they had built in a connection for a second CC pedal. That seems like a real and unexpected limitation on a high end workstation.

To the OP GB not Go

The unit symbol for the gigabyte is GB or Gbyte, but not Gb (lower case b) which is typically used for the gigabit.

4GB

Maybe it was a cost thing?
