Xpantastic!

Hi !

I agree. If you speed up the CPU, all the software generated processes 
speed up too, not only the attack of envelopes.
Eventually, if the envelopes become faster, isn�t it they will be 
shorter also. One of the Xpander/Matrix12 advantages is, the duration of 
an envelope can be very long, especially if  the segments of the 
envelope are modulated.
I also think, all the Lfos would speed up, the track generators and the 
ramps,- their slowest settings would be faster then.
What happens to all the software generated VCAs ? I cannot imagine ...

I have a Roland D550 w/ a Musitronics memory expansion and speed kit as 
also midi-multimode feature.
This results in a faster response on incomming midi notes so the delay 
of notes if playing chord are reduced a lot.
The machine is 4 times faster w/ this kit.
The speed kit speeds up the cpu also, but they burned a completely new 
OS in a eprom on a daughter circuit board which compensates the LFO 
speed as also any other by software generated modulators for soundwise 
compatibility of all the patches for standard D50/550. The kit also 
includes a new quartz and some other new components on the daughter board.

So, I think, without a special modified OS for Xpander/Matrix12, there�s 
no solution to speed anything up without to change the behaviour and 
sound of an Xpander/Matrix12.
Could be a bad result if you cannot use all your patches anymore.
