OK, thanks! I had thought of this, but I didn't realize that you could do it without using any actual compression. That's worth knowing.
I got in touch with Roland support. They essentially said the same thing, but they said to go into the Sonar software, plug in basically any effect, and gas up its output.
If you are just looking to boost the volume of something coming into those inputs, do you think it makes any difference whether you do it at the VS 100 or in Sonar? My suspicion is that it is better to do it in the VS 100.
Any info appreciated. Thanks!
