Impulse

This is a simple but nice-sounding synth that I received bundled in Mixcraft 5.0, but last time I checked it can be downloaded for free from the developer. I believe it is still bundled in 6.0. It is great for pads and basses. It can do a nice Solina string synth imitation. Overall, it kind of reminds me of an Oberheim Matrix. It is light on CPU and easy to tweak. Try layering Impulse with Synth1 for some nice 70's-80's synth washes. I'd rate it above such standard VA synths as TAL Noisemaker and Tyrell N6, but behind Synth1.
