Preload is basic instructions to load your sounds from disk upon power up, and means there is no Yamaha style of Flash Memory available. Otherwise they would have promoted and advertised it.

The Kronos is similar to the Alesis Fusion, but more professional.

Alesis Fusion had an 80gb hard drive built in, you could save samples to the hard drive, it had 4 sound engines, but you always had to load your samples to use them. Yamaha is the only synth company that uses Flash Memory that you don’t have to load upon power up because with Flash RAM sounds are already instantly available.

Korg will come with Flash memory options in a synth after they come with the Kronos Pro/EX/Studio/LE/Xtreme/CD models for the next 6 years.

SSD is flash. And Sharp stated in the 'feedback' thread that it apparently takes 10sec to load 1GB of samples, and you can tell the KRONOS to automatically load your samples at startup.

Still need more info on what has to be loaded and what gets streamed. The initial specs claimed that out of the factory over 700MB of the RAM is already allocated for the onboard expansions (why aren't these stored in ROM?).

Just so people know a little more about the Yamaha FlashRom Chip.

On a Tyros 4 it takes over 1 hour to write 1GB of data to that memory. Yes.... over 1 hour. And when your done, if you want to at any point changes something or add something, it's going to take a while. How long depends on how much you want to change.

Fill the 1GB chip and you can add 1 minute to the bootup time of the keyboard. I see no reason to suspect it's any different for the motif.

Regards
Sharp.

Kronos boots up in 10 seconds. Beat that on Yamaha XF. kday is very wrong.

re: "When the machine is cut on all the sounds has to be loaded"

The way Korg does it, only a very small portion of the sounds have to be loaded at power-up, so boot time is fast. The rest of the sound is streamed off the SSD in real-time as needed.

re: Flash Ram there is no load time it's already loaded upon power up.

For whatever reason, machines with regular flash RAM don't load up instantly either.

I would not assume a Kronos boots more slowly than an XF (or any other flash board)... let's wait until we can try it and see.

There's also the issue of "fast enough." If a unit boots in 10 seconds, that's fine. If another unit boots in 5 seconds, does it really matter? Especially if the one that boots in 5 seconds has far fewer sounds? Once the Kronos boots, you have access to 12 gB worth of sound out of the box (expandable to 30). Even *if* some flash-based unit boots more quickly, it will not have nearly as much of a library available. Hey, an actual Rhodes piano has zero boot time, but it only gets one sound.

The point is, until we get some actual boot time specs, this conversation is completely academic.

re: "Flash Ram plays like ROM with no type of drive issues or problems associated with hard drives including SSD."

My understanding is that the faster Flash RAM and the slower flash used in SSD (or even SD cards) all can degrade with extensive writing. When it comes to keyboard use, there is much more reading than writing, which helps keep them extremely reliable for the long term. But I'm at the edge of my knowledge here.

Flash Ram is far superior to SSD hard drives.

SSD drives are gonna fail like typical HDs, you're gonna have to replace them over time from use. The brand compatibility may change over time and finding the right one needed may become scarce over the years, just like a typical hard drive.

The Kronos is just a better version of the Alesis Fusion.

It's not on the Yamaha Flash Ram technology scale yet.

They may implement that in their next set of synthesizers in 6-8 years.

if they implemented this ssd/dfd in the right way and i think they did, flash ram is completely unnecessary and too expensive option of limited value in today's world. I will disassemble the Kronos when i see one and check out all of the details, but dfd way is a better way. And ssds aren't problematic at all in terms of reliability or fail easily. Very reliable and fast technology.
