ANYWAY, there were absolutely no latency issue with Oasys, and i have no latency issue with kronos so far. (unless my ears need 8ms to send the sound to my brain) ! |

Assuming you're less than 45 feet tall, that seems unlikely. But the amount of time you need to process the signal in your brain depends a lot on the user.. _________________ Motif XF8, Kronos-88 (ordered), V-Synth GT, DT-Extreme eDrums

Speaking of latency, are there any pipe organists in this group? _________________ ”It’s easy to play any musical instrument: all you have to do is touch the right key at the right time and the instrument will play itself.”

Well I studied it at Uni, don't get to play one often these days! |

I played normal organ and the lowest 'footmate' (sorry don't know the english term) is 16' which equals about 5 m. I don't know if 32' also exist (that would be 10m).
Since the sound is travelling up through the pipe and going down after reflection it takes at least 20 m.
Sound travels with about 300m/s so the latency is 67ms.
Note that for small pipes (2') the latency is only 4 ms and the 'normal' is 8' which results in 16 ms. _________________

Then you have to add the latency for the distance from the pipe to the performer's ear as well as the delays in the electro-magnetic keying system. Adding everything up the total latency can be a significant amount, so much so that you may be playing several notes ahead of what you are hearing. I had a friend come down to the Elks Lodge in Los Angeles when the great Robert Morton organ there was still in its prime. She was an accomplished pianist but could not get more than a few notes played before giving up. _________________ ”It’s easy to play any musical instrument: all you have to do is touch the right key at the right time and the instrument will play itself.”

...without mentioning the latency of an organ equipped with a tubular-pneumatic traction |

To all of which you can add the sometimes remote position of the console in vast resonant buildings....still, it's a tremendous feeling to play in some of those spaces though! |

Forgive me for bumping this thread again, but I'm surprised this chap didn't try loading another 2Gb RAM just to see if it works.
I'm starting to feel that the stock 2Gb isn't enough. _________________ Synth DIY Projects |

Other options? ARM? VIA? Both those are lower-power consumption chips, but I wonder if the performance would be good enough. AMD Fusion APU is optimized for graphics performance so I don't think it would be a good fit for the Kronos. |

Intel has other Atom CPUs that are more powerful, D510 is not the best. That's all I'm saying. |

If the D510 is good enough why not use it. Development of a synth takes years and changing a processor during the course of development might take quite some risk and time. _________________

True, they could have used the D525 (1.8Ghz vs 1.66Ghz clock speed). Looks like the same cost too, but it launched a quarter after the D510 so maybe the timing wasn't good to incorporate it into the Kronos.
I feel that Korg should have gone instead with a ULV core i3 as long they were planning to use a fan. This one in particular has only 5 watts more power consumption, but is a huge leap in performance and can accommodate up to 8Gb RAM. 'Course it would added $50-100 to the overall price too.

Maybe they could have made different versions of the Kronos--the low performance Atom and the high performance Core at different price points. |

Hopefully that will be AFTER they create an SV-II version of the Kronos that has the piano/organ/ep/HD-1 engines, with weighted 76 note action (C-E), joystick and ribbon on the top panel, weighing under 30 pounds!!!

I think it's a natural progression, I'm certain the next flagship workstation from the big 3 will have a better CPU (using a low-power 22nm process) than the Atom that can accommodate loads of additional RAM.
...BTW you forgot about physical pads!!! |
