Audio Modeling’s SWAM modeled instruments are currently on sale for both computer and iPad versions.
These are truly some of the most authentic, expressive acoustic models available, in particular the saxes and solo strings can be jaw-droppingly realistic.
Especially if you have an iPad, the price while on sale is a no-brainer… $65 for all four saxes, same for all four solo strings. I have had no problems controlling them from my BK-9 via USB, and the latency is negligible. They are quite simply head and shoulders better than anything you have in your arrangers.
At the iPad price it’s worth getting the bundles. If you only have a computer or laptop, the bundles are $175, still a deal (normally $250) but playing them live might be a bit more of a hassle.
If you are into playing sax sounds or violin/cello things, give these a go!
An arranger is just a tool. What matters is what you build with it..!
