[net.music.synth] Korg DW-8000 comments

	I've been to a decent store and been able to see
for myself the answers to my original questions.
I am just about sold on the Korg, but the store has a
Roland JX8P next to it, which has 2 less voices but
crisper sound.  The Roland alos points up a shortcoming
in the Korg, which I hope people can tell me how to get around:
Both the AX80 and Roland can apply the two EGs separately
to the two oscillators, thus getting different ADSR envelopes
on the two.  If the two oscillators are putting out different
type sounds, this means that the mix changes in time.
	Main use of this is to have one osc do the main tone
with a slow envelope, and the other one do an attack transient
(high harmonics, noise, whatever) with a very quick AD and
zero SR.  The Roland gets very realistic attacks for bells,
harpsichord, harmonica, etc this way.  The AX80 seems to
have this ability too.
	The Korg mixes the oscs together first and
then inflexibly applies one EG to both of them; the other EG
is likewise hard-bound to the VCF.  So far, it seems that the
DW-8000 can get attack transients only by attacking with the VCF
open wide, then quickly closing down for the sustain.
This works OK for steel drums (No. 44), where the attack is
high harmonics and the sustain is a dull tone,
but won't work for brass, where the sustained tone is almost
as bright as the attack, just different.
Also if the attack is noise, the VCF won't cut it out completely
on sustain.

How do you get around this?  Am I missing something?

Also the Korg has no cross (ring) modulator (multiplier).
I guess with those prestored waveforms it isn't as necessary,
but ring mod used to be a standard feature on synths
(even the Radio Shack Elton John model had it!).

Is there any way to move a patch from one numbered slot to
another (other than manual write-down and entry from scratch)?

PS: the Korg Poly800 and EX-800 midi slave have THREE separate
EGs -- for each oscillator and the VCF.  Still no cross-mod.
