Subject: Re: Aw: [chromapolaris] OK - I Have Diagnostics Now And They Are Weird

From: Tracy Barber <adirondack_pc@...>
Date: 2018-06-03

I have a Windows 98 PC and a Windows 7 PC with Librarians and Midi Ox on them. Doesn't let me load a bank.

Finding an Atari would be like searching for a hen's tooth. I do, however, have a Yamaha CX5M computer. Good idea, to see if I can make contact, but it would be worse than me trying to find the elusive transformer for my Ensoniq Mirage. (Actually, someone made me a pair of transformers to do the job. This will be really funny when it arrives!)

try to remote control your Polaris.

 

E.g. find an old Atari ST and run the programms which
are delivered over the Polaris-Page.

See POLARIST.PRG 

 

at http://www.rhodeschroma.com/?id=polarisataribankloader

 

Any other control over Midi may do it the same.

Betreff: [chromapolaris] OK - I Have Diagnostics Now
And They Are Weird


 




 

This is a LONG message with test results:

 


These were all done
sequentially, 1 after the other in the Diagnostics
section.  These are exactly the same issues I
was having before reseating / checking the Synth so no new
problems crept in.

 

Removed top left, top
right boards.

Removed power
supply.

Reseated all
connectors.

Tightened all
screws.

Tightened all
jumpers.

Removed keyboard.

Reseated ribbon cables
and made sure they were aligned.  No tears,
etc.  New face plates.

Checked for bad cables
/ connections.

Did not check board
trace for anomalies.

Batteries are brand
new.

Did not remove
transformer and anything in that corner.

 

     
Green cable from headphones is attached to power
supply but nothing else.  Paul D. mentioned
using the brown wire from back board harness
instead.  What do I do with this
cable?  Ground it somewhere?

 

Changed startup patch,
it was going to I 10 and that was always weird.

 

Starting
Diagnostics:

 

1) Scratch patch
worked.

2) Channel enable
worked on all 6 channels.

3) Tried playing with
Pulse on the Oscs but it just gave "effect" - was
it suppose to turn off the Osc?

4) LF D 2 - Revision
5.  Poop.

5) LF D 3 - All LEDs
light up.

6) LF D 4 - LED went on
at max Master volume.

7) LF D 12, STOP: Did
NOT try.  Already in RESET mode from
before.

8) LF 10: LED lit up
and it honked.  No MIDI set up at the
moment.

9) LF 11: LED did not
go on and I heard a click.  Had to power off /
on.

10) LF 12: 
LED did not go on and I heard a click. 
Had to power off / on.

 

At this point, heat
sink is getting warmer...

 

11) Noticed Bank B had
organ sounds which it should not.  If not
mistaken, it should have scratch patch because I previously
did a RESET.

12) Tried to go through
all of "A" Bank using the numbers. 
Started each at A1 and proceeded through all. 
Results:

 

     
A1 - OK

     
A2 - OK

     
A3 - Piano?

     
A4 - OK

     
A5 - OK

     
A6  - OK

     
A7 - Honk, then went there to A7.

     
A8 - Moved to G 8

     
A9 - Moved to H 9

     
A10 - Moved to I 10

     
A11 - No LED, Click and stayed on A1 - no
sound.  Turn off / on.

     
A12 - No LED, Click and stayed on A1 - no
sound.  Turn off / on.

 

At this point,
frustration starts to set in.   I think I
need to focus on adjustments or some new part(s) in the
Synth. 

This is where I ask you
the questions about where to go next.  I have
done the preliminary work and am not afraid to go further,
but don't know if I'm wasting time here.

 

13) LF A 1 - 5 seemed
to work.  2 gave me a click.  5
gave me a honk.

14) LF B 1 - 6 seemed
to work without issue.  

     
7 gave a honk and went to flashing "F".

     
8 gave a honk and went to G 8.

     
9 gave a honk and went to H 9.

     
10 gave a honk and went to I 10.

     
11 gave a click and went poof - locked up. 
Turn off / on.

     
12 gave a click and lit up B 1 - 3. 
Locked up.  Turn off / on.

 

Sheesh...  Warmer!

 

Press "A" 2 -
12 light up.

Press "B" 2 -
6 light up.

Press "C" and
"A" stays on.

Press "D" and
"A" stays on.

Press "E" and
"A" stays on.

Press "F" and
"A" stays on.

Press "G" and
"A" stays on.

Press "H" and
"A" stays on.

Press "I" and
"A" stays on.

Press "J" and
"A" stays on.

Press "K" and
"A" plus 2, 8 - 12 stay on.

 

I think this sucker is
bipolar.  No pun intended. 
What's funny is that the presets play
fine!  However many different ones I can
scrape out of it, other than scratch patch. 
LOL!

 

Any ideas?

 

Tracy
