Having just bought the Samplicity L96 impulse response DVD, I wonder if this will be sufficient for me, or if I will eventually have to go for Altiverb.
It seems to me that Altiverb is full of features that are great, but which one does not really need to create a good emulation of various rooms - for example the ability to place the speakers anywhere you want. Also, Altiverb comes packed with tons of IRs from various existing concert halls and so on, but I wonder if this makes that much a difference to your music compared to just using the IRs from Samplicity. I mean, sure, the Samplicity IRs may not come from fancy places such as the Sidney Opera House, and they may have more anonymous names such as "026 - Large Hall 1" - but judging from the demos, the Samplicity L96 library can sound pretty damn good.
One difference I imagine can get annoying is that you can change room size and reverb time etc. in Altiverb, whereas with the Samplicity IRs you have to load a completely different set of IRs. At least that's how I think it works, I have yet to receive the Samplicity DVD, so I haven't tried it out yet.
Have any of you guys tried both Samplicity + Altiverb?
