My ambika seems to be working well. I have 5 voice cards up and running. It sounds great.
I have a picky problem. The cluster of 7 LEDs do not seem to be working right. The top light blinks in sync with the LFO in yellow. The top left light of the 6 others is always yellow, but it also displays green when voice card 1 is called into duty. The one next to it displays green when voice card 2 goes on. The next row shows green for cards 3 and 4. Voice 5 light never comes on even when voice card 5 is called up. 6 never lights up, but there is no card in slot 6.
None of the other 5 LEDs ever show yellow. I’m not sure exactly what these lights are supposed to show. I haven’t tried moving cards around to see if anything changes, but will wait for a suggestion. Again, this problem does not concern me except for visual aesthetics.

The part and voice LEDs LP1…LP6 indicate which part is active (green lights), and which voicecards are currently playing notes (yellow lights).

From your description:
It looks like color are reversed (yellow indicates the active part ; green indicates the voicecards playing notes). There’s a setting in the preferences allowing you to swap green <-> yellow.
Voice 5 LED is off, maybe due to a bad soldering join on the LED itself, its current limiting resistor, or the 74hc595 that drives it.
I guess this was an RTFM problem. Swap was on, when I turned it off the colors work perfectly. There was indeed a bad solder joint somewhere in the chain. I am fairly certain my last voice card will work when I get the new chip put in. Thanks again for the support and suggestions.
