Alesis Andromeda A6

i did sample and display the vca/envelope of the a6  and the 
roland system100m vca/envelope. took noise samples of 
0.5sec.

 all samples together are 936kb. if somebody want's to compare 
one of his/her synth's, this little test bundel can be mailed or so.
(just sample the attack and therafter the decay of the old synth.
white noise, preferable bypass filtering, length 0.5 sec about, . 
compare it 's view with the a6 envelops and give  me or this side 
a notice on the different shapes that resemble most closely.
that's for the databank testing)

some about the result sofar for the system 100m envelops
the attack on the a6 can be set on lineair or exp1 ( the 
system100m has 2 characteristics: lin or exp),
the decay more strangly, accordingly to the picture , would more 
benifit of a log2 ( for the system100lineair decay!) or log3 (for the 
sys100expotentieel decay).
what's in a name?


a jpg.picture of the test can be found under "Files"!

Cool. Which Engine Optimizer setting did you use (VCA)?

Easier,

-Mike

Yes, VCF,

Sounds like you could use a VCA calibration (check the Tune page,
select VCA, and let it autotune after it's done with that). 

The output VCAs are on the Filter chip, so the Filter optimizer
setting effects them as well. Working on a Minimoog sound, the Fast
setting was actually too fast...

The Fast optimizer setting for the Filter/VCA chip didn't sound right
when creating a Minimoog sound, in direct comparison to a Minimoog.
The next slower setting sounded correct, if my memory serves.

It's okay, if you add subtle things such as different amounts of
vibrato to each oscillator, etc. to mimic the unpredictable nature of
the Moog.

The Mini's?

yes. please see issue in bold below.

Cool.


>please see issue in bold below.

You may want to contact Alesis support at support@...,
or Numark directly if you are having problems with your A6. 

Easier,

-Mike

Do you know whether the tuning issue I cited is normal for the a6- i.e.,
endemic to it?

You really should contact Alesis if you're having a problem with your
A6. What's the hesitation?
