After the first phase where a sample gets played LS has to mix these samples into one or more audio output streams. LS, as opposed to GSt, has very little signal overhead in it's channel level mixing buses as well as it's output mixing buses. This will create severe distortion if you mix even a few notes at the same time. GSt has very much more overhead and doesn't run into this problem to such an extent although it has the same sort of limitations. If you start driving LS very hard with channel volumes up then you will likely run into this pretty quickly and have to pull them down anyway. Whether you are an LS user, or a GSt user such as I am, I suggest that you look very carefully at MIDI velocity events in Rosegarden, most especially if you are using any of the larger orchestral gig files. Lowering MIDI velocity will generally give you more realistic sampling of what a real player does most of the time and allows you to save the high velocity samples for times when players are really laying into their instruments. Set output volumes in such a way as to get the highest S/N you think you can without clipping LS outputs. With LS I would always output each instrument individually and then record and mix them in Ardour where the mix buses worked better. No on-list comments from me on this one other than to say I didn't have much trouble at all with qsampler a year or two ago when I was still involved with the LS project. Cheers, Mark
