I quickly downloaded a copy of Audacity, because it's free and I needed something to record with right then. Unfortunately, the default metering setup in Audacity is pretty thoroughly inadequate and we ended up with clipping on a lot of the recordings, because the resolution of the meters was set too low for us to see the clips. I wasn't thrilled by this.
Ok, we could adjust the scale on the meters, which is probably a pretty good idea. But before I got around to playing with that, I got an offer from Steinberg for the cut down versions of both WaveLab and Cubase for $179. And it seemed like it would be really nice to have the software that I was using in the studio available in the field, even if missing a few features, without having to worry about taking the dongles out of the studio. So I downloaded it.
Tonight, I've gotten it installed and set up on the laptop. This greatly improves my chances of recording Seanan and Wild Mercy's concerts without incident.
We'll see how this goes.
