Hi Jules,
I think the program list you're referencing is for the K1000 PX
Expander - the rack module. The program list for the K1000 keyboard
is slightly different and has the tuning note at 179. (See page 63
of the K1000ProRef.pdf).
Some programs not playing over the whole keybed is normal. For those
instruments, either it's not possible to record usable samples in
the extreme low and high notes, and/or the samples that they are
using don't stretch well beyond the native range of the sampled
instrument. That's also why the usable range is different across the
programs you listed.
I can't explain the UART test fail, but since everything else is
working, if it was me, I'd ignore it. :-)
Best regards,
Michael

Hello everyone!
New K1000 keyboard owner here since last month owner :-) and very
happy to have found this community.
I have taken some time and am still trying to get to know this
beautiful machine better with the help of the precious collection
of infos on the k1000.net site.
Before unmounting the main board though, I would need some little
advice concerning the flaws explained a little further down.
Hope somebody can help :-)
So, here is what I have so far:
roms installed: u50 u51 u54 u55 u58 u59
the unit seems to be in original state without any modifications
the relay on the mainboard is a Matsushita with clear top (have
already ordered a Panasonic one just in case)
I am only testing through the headphones for now (!) and it sounds
good, all keys play, ram works, I can save sounds in user memory
Have slightly dusted off the interior and the mainboard, then did
a hard reset and went into diagnostic mode, runned all self tests
with one UART fail

Now my problems:
1)
the last program is 179 (tuning note), not 184 !?
after comparing with the program list from the manual I realise 5
programs are missing:
160 (mono pressure vibrato clarinet)
158 (poly pressure vibrato clarinet)
148 (pressure tremolo vibes)
138 (mono pressure strings)
132 (piano & vibes)
It is as if they were just not on the ROM ??!?
Can somebody explain that?
2)
Programs 03 through 08 are not playable over the whole keyboard
(see list below), which means some keys to the left and some keys
to the right just make no sound. This occurs of course with all
associated programs that use the same sample soundfiles.
Changing the low note and the high note of the layer in the edit
menu doesn't change anything:
program 03 (choir) G#1 to G#6 only
program 04 (vibes) F#2 to D7 only
program 05 (acoustic bass) A0 to E4 only
program 06 (trumpet) C3 to F#6 only
program 07 (baritone horn) D#2 to A5 only
program 08 (clarinet) F2 to G#6
Funny enough, the range is different with each of these programs,
ROM tests show no errors.
Other programs like 01 (grand piano) play fine through the whole
keyboard.
Still, I pushed down all roms slightly, dusted them off and at
first sight the eprom legs don't seem to be corroded (?).
Until I am not sure that the problem doesn't lie elsewhere, I'd
rather not take them out, because they seem to sit in there quite
tightly.
So much for now - I hope someone can give me an advice.
greetings from Berlin!
Jules
