Creating Keyswitches in LA Scoring Strings

LASS Keyswitching with the Auto ArrangerThose of you that use it know that LA Scoring Strings is an incredible tool for creating realistic string mockups and recordings. But it can be a little daunting at first, especially with the A.R.C. and all of the complexity (and power) that brings. When I first started using LASS, I didn’t know how to set up keyswitches and quickly retreated to putting different articulations of a string section in different Kontakt instruments just so I could get my piece finished.

I’ve recently been mixing a piece for a fellow composer and saw that he had used exactly the same workaround that I originally had—placing each articulation on a different track in his mix. I realized there may be a lot of you out there who haven’t yet found the excellent video tutorials on the Audiobro site, so I thought I’d share those. As you can see from the video, setting up keyswitching isn’t all that complex once you understand how it’s done, but if you don’t know how to do it you’d be hard pressed to work it out on your own. The best part is, you only have to set it up once and then save your template in Kontakt.

There are also a few extra tutorials hidden away in the forums, including one on how to set up keyswitching so it works with the Auto Arranger. This one really had me stymied until I found it, in part because I was using a smaller ensemble of just first chairs and part A players. The secret I discovered is that in cases like this you need to go into the SubRules(A) tab and set up rules for two-note harmonies, otherwise LASS won’t know how to assign the parts (see below). Once I did this, everything worked perfectly.


If you own LASS and haven’t watched the tutorials, I highly recommend you set aside an hour or so and watch them. The A.R.C. interface can be intimidating at first, but once you know the ropes it actually makes a lot of sense, and the folks at Audiobro have packed a lot of power into it. And if you have additional questions while you’re working, the forums are an excellent place to ask. Andrew and Sebastian are very responsive, and I usually haven’t had to wait long for a helpful answer.
