OK cool. I didnt try this outsim synthmaker so i am not too familiar with it, but from what i have heard, the plugins you made in it can be bit CPU hungry and can have problems with sound glitches and so. check for the latest version. is it 3.0, i think,.? but i am not sure.. As you said CPU is 6% which is ok. Maybe comparable to commercial stuff, even you can do much more with commercial.. but I dont want to be dishonest to your effort so go on, mate. Looking forward to hear this and will also grab the one you put in other thread. good good.
