I have to agree with James,
The Chroma sounds better than the Xpander/M12.
I was suprised when I got my Chroma a couple of months ago, and
compared it to the M12 in mono (as opposed to having the voices panned
as usually) The M12 sounded a bit "boxy" and lacked low-and-highend
compared to the Chroma.
The Chroma also has a more defined 3D sound.
Before any flame starts, I want to say that I love the M12 to death.
It can do stuff which no other synth can do, and I´m sure as hell
ain´t getting rid of mine. And of course every synth has "its" sound.
I´m talking about the actual soundquality here, where the difference
might be explained by:
1.Chroma has discrete oscillators
2.Xpander/Matrix-12 has inferior OP-amps in it´s signal chain.
As a matter of fact I´m in touch with a guy who changed the OP-amps in
his M12. This is what he said:
"The sound differences compared to the horrible TL072's that were in
there,are better low end and clearer top end. TL072's have the same
effect on sound that clock jitter has in digital systems; a folding of
the high frequency content into the mid bass band, in the form of ugly
grunge. Due to other design issues the Matrix-12 will never have the
huge sound of a modular Moog. There are too many compromises in the
design and CEM chips. But it can be made much better"
He also bypassed the pan-circuit which degrades the overall soundquality.
He is going to explain in detail what he did (and how) as soon as he
finds the time.
Xp/M12 is one of the greatest synths EVER, and IMHO it deserves to
sound as good as it can.
Of course YMMV
