I realise that these are two completely different apps, but I am after some opinions to help me make up my mind.
Here's the scenario:
- dp (upgrade price from my old copy of Performer) is close enough to the same price as MSI for me.
My current computer is a TiPB 550MHz with 512MB of RAM.
I own Live v.4 and do like it.
I also have the Arturia Minimoog v plug in and that really makes this computer sluggish.
I also own some outboard synths that I intend to trigger via MIDI.
Since MSI is a cross platform plug-in do you think it will cost again when it is released for the MacIntels?
What about dp - if I spend the big dollars now, am I also destined to spend the big $ again when it is released as a fat binary?
I like Live (so, yes I already own a sequencer) - but I also cut my teeth on dp at Uni and want to get back into using it again. However, I keep thinking that audio samples of an orchestra won't be rendered useless when I move to a new Mac, but my version of dp might.

On the other hand, maybe the samples in MSI will be too taxing on my ageing PB. If this is the case, then perhaps I'm better off spending the money on dp and recording MIDI tracks and the odd vocal or instrumental solo.

Is my thinking flawed? Do you have any pointers?
TIA,
Anthony.
