[A6] Faulty Andromeda Number 2

[Moreno RENGA]

Hello Stevie,
 
1)      Check that BkTune & TmpTune are On in the Tune Page (Auto Tune
knob).
2)      Test this to see if it’s any better and suits you: 
-          Load the default program.
-          Switch on the arpeggiator (without the sequencer) with no
octave steps.
-          Switch VcCurve to Max in the Global > Kbd page, this will
avoid that your keyboard is sensitive to velocity thus resulting in a
different filtering in each pressing (and you know that humans can’t
press twice with the same force/speed, just like a drummer). Actually it
still is, but it’s always using the maximum Velocity. So each time
you’ll press a new note it’s always the max.
-          Go in the Kbd page (Poly/Mono knob) and try the 2 different
voice assignments (Assign parameter) that are “Lowest” & “Rotary”. You
should know that each component of any analog synth. has its own
character. If you set it to “Lowest” the Andromeda will always first
play the lowest voices and this will result in a more “uniform”
performance. OK this might not solve your problem in multi-mode if you
use many different voices, but even with all the sounds performing
together, you won’t maybe even notice the differences. In “rotary” it
will use all voices in rotation. Here with my A6, both suit me, there
are just very slight differences btw all voices but it’s normal and it
even sounds nice, not flat. But I have my synth. now for ages. I know
that because of law regulation Alesis isn’t allowed anymore to use
certain metals for soldering. Might be a time adaptation difficulty

 
I hope that the earlier parameters I proposed you to check will solve
your tuning problem though.
Don’t despair, it’s an outstanding great synth!

About a month back I posted about my new Andy having tuning issues and I
was not alone as I see from the other users on this list who had the
same issue with their new Andy's. I sent the faulty unit back to Digital
Village and got a replacement which again has the same issue. This is my
first analogue synth and I've had no prior exprience with them so I just
want to double check with Andromeda owners that there is actually a
problem and its not me doing something stupid. 

Firstly, I turn on the Andromeda and leave it to warm up for 20 mins at
which point I run autotune. Once complete the Andromeda indicates all
voices/bands are in tune and OK. Then, I restore the default program and
play 3 or more notes repeatidly and the pitch seems to be different
every time. On some presses the sound is ok and sounds in tune, on
others it sounds like the osc's are completely out of tune. I noticed
there are a few mod routes setup on the default program such as LFOs to
filter frequency so I switch all these off. Ring mod is also active so I
disable it too. 

I've tried running through each voice at a time with the others disabled
and on this Andromeda the beating between the osc's is different on each
keypress on almost every voice. If I turn sync on it takes away the
beating completely (as you would expect) however it still sounds out of
tune to my ears. I would expect the osc beating to beat at the same rate
on each key press, however the speed of the beating (excuse my poor
terminology here) varies from slow to very fast on each consecutive
press. Are there any other steps I need to perform on the default
program? 
 
I should also note I have tried hard and soft resets, and reflashing the
os with no joy on the first andromeda. I will try the same on Andy
number 2 this evening when I get home from work. I'll also post the
serial number to prevent this unit from circulating else where. 

I know analogue synths 'drift' but my concept of osc's drifting slightly
and being out of tune are 2 different things. Can other andy owners
please confirm if i'm being stupid or there is in fact problems with the
two Andromedas i've received? 
  
thanks,
stevie
