Thanks for your help guys, there's some good tips there that I will try out. I actually use Cubase 64 bit as my DAW, but this evening I just found out that the Steinberg Virtual Guitarist 2 effect plugin has a couple of really good acoustic presets. I can't use VG2 with Cubase anymore (it doesn't sit well with the 64 bit) but at least I can still use the plugin in BiaB.

It's nice to get a good sound in BiaB before importing to Cubase, and I'll now see if the VG2 plugin still works in Cubase. I hadn't thought of trying it before, I just thought that VG2 didn't work anymore!

Sorry, should just let you know that I've only started working with BiaB in the last few days. I had some godd song ideas but I always struggled to get the arrangement working. BiaB is giving me some great ideas and I think it's pretty amazing.
