        This appears to have opened a whole can of worms about which I know 
nothing!

	Forgive my ignorance, but of what use would they be if, once Swami is closed, 
nothing is remembered? How does Fluid then produce the required effect.

	Clearly I have to go away and do a lot of digging about this, since I'm 
completely in the dark at the moment. But I wonder if you could give me a quick 
clue: I've found the 'modulators' bit in Swami (always wondered what that was 
for...) and it seems as though it's tied to a specific patch. If I click 'new' 
then I see that the panel at the right showing 'source', 'amount source', a 
multiplier symbol and 'destination'. I might guess that 'destination' should be 
'patch', but that doesn't seem to be offered in the drop-down menu. I'm a bit 
lost also about what 'source' and 'amount source' should be: I can see 
controller number 74 in the list for both of those and I would guess that I 
should select it for one or the other but what of the other input to the multiplier?

	If this is something that can't be answered in a few words, don't worry because 
I don't want to waste bandwith and bore everyone else on the list - I'll go off 
and see what I can find out with Google.

        Yes - I think that that's about it.

        Cheers,
