Harmonic distortion after OS 1.2.1 upgrade

[danatkorg]

Before commenting on anything else, I'd like to note that this part is very problematic, and absolutely NOT recommended:

So the proposed sequence is:
a. OS 1.1.0 full internal hard disk format & re-authorization. [Done]

In addition to requiring a re-authorization, this will completely erase all of your hardware's calibration data for the aftertouch, joysticks, control surface, etc. This will in turn almost ensure that it does not play the same as it did coming from the factory, rendering comparison difficult.

Re the Format command, the manual says:

IMPORTANT: Normally, you should not need to do
this–and you should avoid using this function if at all
possible. Always try using the Restore OS and factory
sounds option first.
However, if for some reason the internal hard disk has
been completely corrupted, and using Restore OS and
factory sounds does not fix the problem, this will
allow you to restore the hard drive to its initial state.

Take this seriously. This is the only situation in which Korg recommends using the format command.

Best regards,

Dan

Hi Dan,
I was forced to do this. If you look at the other post regarding attempting to downgrade from OS 1.2.1, it did not work untill I tried the full format option.

I tried putting the OS 1.1.0 install disks and tried option 1, which was to only restore the OS and factory sounds, after that I tried re-authorizing it, then after reboot, the reauthorization was not applied. I tried repeating the install once again, still not results. The only way I could get the OASYS to boot and play again was to perform a full re-format and wipe the hard disk clean. This allowed me to complete the authorization sequence. I am this stage right now.

It is not my fault that the OS 1.2.1 upgrade some how prevents re-installation of the OS back to 1.1.0, without formatting the internal hard disk.

If after I have completed the test scenario to stated earlier, how do I get my control surfaces calibrated?

I mean if the global setting have been altered after loading the LAC-1 PCG file, then I should not automatically assume that the velocity curve was the only setting that was altered.

The update instructions including steps to load the LAC-1.PCG file. This file contains only a single bank of Program data for USER-D; it does not contain any Global data, and loading it will not make any changes to the Global settings.

The update also installs on the disk, but does not automatically load, a new version of the complete preload data. This file includes the factory presets for all user data, including the Global settings. If you have noticed any Global settings changing after the update, my first question would be whether you loaded the LAC-1.PCG file, or the new full factory preload file.

In response to this thread, we've just done another test and confirmed that the 1.2.1 update does not over-write Global settings.

Best regards,

Dan

I have read all of your posts - but I don't see that you had to downgrade in the first place.

I have to ask: did you contact your Korg Distributor's tech support before formatting your drive?

You'll need to contact your Korg Distributor for assistance; they can find the information in the OASYS service manual. I'm sorry that I can't offer the information to you directly, but I have been expressly instructed not to do so.

I thought that the analog output stages were 24-bit 96Khz for playback and that internal re-sampling occurs at only 16-bits and 48kHz, so clearly there is more headroom in the 24-bit 96kHz playback than the 16-bit 48kHz playback to discern such a difference. Do correct me if I am wrong.

The analog converters are *capable* of 96kHz operation. However, they run at 48kHz, with the sole exception of the main outputs at certain settings of the Global S/P DIF Sample Rate parameter. For more information, see the diagrams under that parameter in the manual.

Also, you are correct that internal processing is at 32-bit (or higher), the DACs are 24-bit, and internal sampling currently uses 16-bit resolution at 48kHz. Note that this means the internal sampling is still slightly higher-fidelity than audio CDs, and so it should be sufficient to capture changes such as broad tonal changes, increased reverb, etc.

Also - we've now done a number of side-by-side comparisons between software versions 1.1.1 and 1.2.1, in response to this thread. And, before you ask, I'm 38, I can still hear the high-frequency whine of cheap CRTs, I'm in general a critical listener, and I'm using Ultrasone ProLine 650 headphones.

I intend to do a few comparison sequences, which should be easier to evaluate than live playing; I'll let you know when these are ready.

I don't see what's wrong with that! I do it all the time (although I use a decent white wine).

Hi Dan,
When attempting to downgrade, I used the OS 1.1.0 installation disks and then the authorization did not work. I tried this three times.

No, I did not contact my Korg distributor's tech support. The only way I could get the authorization to work was after a re-format of the internal hard disk. It must be a problem with attempting to re-install OS 1.1.0 after an OS 1.2.1 update, with some data being left on the hard disk that prevents the authorization sequence from completing.

Does this mean that I have invalidated my OASYS's warranty, just because I performed a full OS 1.1.0 re-install and re-formatted my internal hard disk?

Hi Dan,
I recorded a couple of performance sequences and did a comparision between OS 1.1.0 (after a full re-installation) and OS 1.1.1 update. I performed all the steps that I planned to do, save global data, create sequence performances, resampled those songs to hard disk including the Teknosys song.

However, I now have another problem, when I put in the OS 1.2.1 update CD, the OS upgrade process does not seem to be progressing. Its stuck for about 10 minutes now. I forgot how long it took the first time. What should I do? Do I wait longer or can I switch off the system and re-start once again and will it be okay? I'll keep it switched on till I hear from you.

Yup, it's been too long, my OASYS has definitely hung mid-way during the OS 1.2.1 update procedure.

I'm not sure why it would hang, but if it's clear that it's not progressing at all, your going to have to power down and let it try again.

If it continues to hang while updating, you may want to try burning your update CD again and using the new one.

It's likely that if you get the update to run to completion you'll have a working 1.2.1 system install. If it finishes but the system doesn't boot or run correctly afterward, you're looking at doing another 1.1.0 install process to get running again.

A warranty is not an "all or none" proposition. The warranty really determines "who pays" when a defect is uncovered, since a defective product needs to be "made whole" again.

Here is the Korg USA warranty (I assume different countries have different warranties):
http://www.korg.com/service/warranty.asp

Some key points:

All Korg products purchased from a Korg USA authorized dealer are warranted to be free from defects in material and workmanship to the original consumer purchaser as listed below:

Damage resulting from the following causes are excluded from the warranty set forth above:
--Misuse, including damage occurring during shipment, damage caused by battery leakage, accident, fire, unauthorized repairs, tampering, cosmetic damage or other types of damage which are the result of improper handling or abuse.
- The cleaning of controls or contacts due to exposure to dirty, dusty, or otherwise contaminated environment.
- Damage resulting from modification.
- Damage to units used for loan or rental.

In your situation (and if you lived in the U.S.), the determination of "who pays" relates directly to what is wrong and who is at fault for that defect

I would assume the only part of your warranty you have violated would be any work required to re-calibrate your OASYS, since that is the only thing you messed up by re-formatting your hard drive.

I assume Dan's caution is a general one: if you have a "problem" with your keyboard that needs "fixing", you should always contact your Korg Country Distributor (the one who provides the warranty) before you perform any fixing yourself. The idea is to allow the Distributor to help solve/fix your problem before any damage occurs.

A more concrete example would be this:
-- suppose I noticed some flickering on my LCD touchscreen
-- Korg USA would WANT me to contact their Tech Support (or an authorized Service Center) BEFORE I opened up the OASYS and started messing around
-- the idea would be I need to give Korg USA a chance to fix my problem
-- also, if I DID open my OASYS and start messing around with a screwdriver and I damaged something, Korg USA would NOT be liable for warranty support on a problem I created.

Hi,
It occured to me that I forgot to remove my new Sony 1GB Tiny MicroVault USB drive from the OASYS. I just got it today and was transferring files to it from the internal hard disk.

I removed the USB drive after powering down the OASYS, left the OS 1.2.1 update CD inside and then restarted the update process. It completed quickly this time and the OASYS booted up just fine.

I have also just completed my tests. It confirms that there is indeed more added reverb for A114 Mega Mute Guitar. The rest I'm not so sure, since my ears are probably fatigued by now. But there certainly is a difference. I also kept track of the global setting for the velocity curve through the entire process and it did not change.

The results of the test is a zip file that is 313MB. Would anyone be able to give me FTP access to a server where I can upload it? It has the sequence data and audio files for resampled performances from the sequencer directly to the internal hard disk.
