Xpantastic!

Hi,

In the modulation pages of the Xpander, it's possible to set a
quantize option to themodulation. The manual of the Xpander says,
"Quantizing cause semitone steps instead of a smooth change of an
Enveloppe, LFO, Lever or other modulation".

I did set quantize for some modulations of some patches, but I really
can not hear a difference in my sound.
I understand what a "semitone step" is if the modulation destination
is the VCO freq or detune, but what is the meaning for an enveloppe
attack or LFO speed ?

In the MIDI implementation, it's possible to enable/disable the
quantize thru a "Modulation edit follows" SysEx message (with
action=05h which is "set quantize on/off"). The same message with
action=06h is "toggle quantize N/A".
Does anybody knows what the difference is between this two messages ?
As far as I know, it's only possible to enable/disable the quantize
from the XPander panel.

Is a patch with a modulation quantize demo available somewhere ?

Thanks,
/Greg.
