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.
This is a very nice synthesizer indeed.It has that "hybrid"(analogue/digital) sound character which is so in vogue. Good filters(6/12/24 db ecc.),two envelopes and a detune function for more analog flavour, with a fine user interface,make this instrument,in my opinion, the best "value for money" one beside Square and Junox2Read Review
For me, this cheap little synth is one of my favorite... It's a versatile and conventional synth, so it's easy to use but what impress me the most is the sound ! Perhaps because of the true stereo mode, and the internal fx. You don't need to add external fx, it sounds so great on his own ! What I also appreciate is that I can use the pitchbend and the modulation wheel of my keyboard, Impulse always reacts great ! The GUI is nice and now the parameters names show correctly in OrionPro or FruityLoops : I have mentionned this problem to Bo Johansen and 2 days later it was fixed, great support ! I don't understand that nobody speaks about this synth !
