my A6 is fine but how to tell if you have voice failure?

i understand that when you push the tune button it tunes all 16 voices, is the voice failure just an F under one of the voices? or will it say more?

That's the idea. I'm not sure if more is displayed because I've never actually had a voice fail the test before.

For a couple days, I did have one of the "bad batch" Andromedas from last year. All its voices reported OK tuning, but playing the synth in rotary voice mode made it pretty obvious that some voices were way out of tune.


BTW, was your Andy made in the USA, or did they successfully offshore the production this time?

Just because the A6 says that everything got tuned properly this doesn't mean that this is always the case. Do this: playa simple sound, disable the effects, then open the Vox Monitor, and check each one of the voices BY EAR, if one is out of tune you will notice it right away. This is how I found that my first Andromeda had 2 faulty voices, I returned the instrument, got another one back which has 1 faulty voice.

Now that I have come to think of it, it's strange because this problem appears in a certain range of the keyboard (I don't remember precisely but it has to be something like 1 and half octave above C3 or C4) regardless of velocity sensitivity settings. On some sounds it's clearly noticeable and annoying, on other sounds you can hardly spot it and on others it becomes a .. feature! In the A6 I have now, voice #12 is the guilty one.. I can certainly notice a cyclic pitch modulation, something like 3 Hz. Ofcourse, you can always disable the problematic voice but for me this modulation is small and not really important, unless the patch I am dictates otherwise. No synthesizer is perfect, you can always find flaws in a $300.000 Lamborghini so I decided to keep the A6 and not get a 3rd one. Very Happy

i had once a complete voiceboard (=print +8vco+8vcf chips on it) changed, followed by an extra swap of just two seperate vcochips . that made him near perfect in this respect.

Sunny how did you arrange the voiceboard change? Was it expensive?

the voiceboard got replaced cause between c1 and c6 there was a tolerance of more than +-10cents. the dual-vco-chips were changed for the same reason as written here above: to much drift/not proper tuning over part of the keyboard for those perticulair voices.
in fact it didn't cost me anything as it was under guarantee, only the travel twice.
i immediately bought an extra 2 dual-osc-chips and 2 dual-vcf-chips plus some knobs and switches. which set me back about 100€ altogether, thereby hoping to be a little prepared for futher problems.

i think the person from the service station said to me a voiceboard (+chips) normally would be someting like 600€, but i'm not sure about it might also have been 450€. the single chips were something like 20€ each.

i also write this down to let know that it's not neccesary the best idea to change all voices at once/ the whole soundboard, if you want to improve your A6. just swapping the most annoying 1 or 2 voicechips ( oscillators come in pairs, two on each chip) will be sufficient. however to find somebody who is well experienced in unsoldering and soldering chips properly ( no they are not socket) might be more of a challenge.

(ps to give a more graphic idea :there is some topic on the forum about the inside guts of the a6.)
