Hello,
I'm hoping someone on the Korg Forums could point me into the right direction. I have a Korg T1, that I still use on stage.. until recently...I had my tactic switches replaced. My A Program bank of sounds are fine. The issue I have now is my B Program bank sounds have totally changed and also missing my T1 drumset. And finally, when I go to load up the T1 master disk, The screen does not show anymore that I can, Load All PCM Data or Load DCM PCM Data... where it did before, All I had done is, replace all the tactic switches... I've been told to reload the operating system.. But for some reason, I can't find any information on this subject.
How can I get and reload the operating system? Is there ram still available or compatible for the keyboard? Any suggestions would be great....
Hope someone is out there...

Re: Korg t1 sound question
The operating system is on a pair of socketed ROMs, so it's not a matter of reloading it. To determine which version of the ROMs are installed, press and hold the 0/FINE button down while you turn on the T1. The ROM version number will appear at the top left corner of the display. What is yours?
When the display doesn't indicate the ability to load PCM data, that's usually an indication that the PCM memory isn't present. Since the T1 came with PCM memory standard, that isn't a good sign. Replacement of tactile (tact) switches shouldn't be related to what you've described, unless more happened than you're aware of.

Why would you want to replace the PCM ROM? They are soldered on board on every PCM synth. The actual PCM ROMs are unlikely to go bad before other components in the synth fail.
If you have lost some preset sounds, you should just find the original sysex banks on the internet and then just dump the sysex file to the synth over MIDI.

The discussion has been about the T1 operating system firmware (not the PCM ROMs), and PCM memory (RAM) for loading samples. You seem to be confusing the two.Juha2 wrote:Why would you want to replace the PCM ROM? They are soldered on board on every PCM synth.

You're welcome.kellykeys wrote:Hey,
thank you for the reply!!!! can I replace the ROM's? and any suggestions on how to replace the PCM memory? will check tonight and see which version of ROM's are installed... Again, thank you for your reply!!!
The OS ROMs are replaceable (since they're socketed), if you can obtain them or have EPROMs burned, but that seems to be getting ahead of things at this stage.
The PCM memory (RAM) is normally soldered to the KLM-1385 board, along with the PCM ROMs. Do you know more than you're telling us about the tact switch repair?
When you post the OS version, I might have additional information.
I am looking for solutions on how the fix the problems... I'm a keyboard player, not a tech doctor....lol... I'm willing to try anything at this point... How do I load the original sysex banks...Do I load this information through the midi input? And where can I get this information? Like I said before, I'm grasping at straws to figure out how to get this fixed.... Thank you for your replies!!!!

If the TSD-00PI disk loads without problem (disregarding the "changed" sounds), then using a SysEx file likely won't resolve anything. However, the internet archive still has the t123pl.zip dowload available:kellykeys wrote:My korg disc is TSD-00PI, blue disc. In the B program band, it shows the correct names, just the sounds have changed.... I have about 5 drum sounds on my T1 drums... Now what to test next???? thanks again for our help, really appreciate it!!!!

I can't be certain, but it seems like your T1 is having difficulty in addressing PCM data on the KLM-1385 board. That could explain incorrect sounding Progs, missing instruments in the drum kit, and the inability to see the PCM memory (RAM).
Since you indicated that this began recently (after tact switch replacement), it's possible that improper reasssembly after the repair may have led to the issues. Something as simple as a connector that didn't get fully seated can cause problems. The harness going to the KLM-1385 uses a 60-pin connector, so mis-mating isn't hard to do.
If you're certain that the problem began right after the switch service work, then I think its appropriate for you to bring the issue up with the servicer.
If you aren't sure that the problem relates to the previous service, then I'll be glad to suggest further troubleshooting you can do.

check the ribbon on the pcm and rom board if its not seated properly and the pcm is not seen
it will revert to standard t2/t3 with out pcm
it does a routine check when booting and if it does not find it it then only loads the software related to presets and not loading pcm
so check that ribbon cable make sure it is seated down all the way
