A slight improvement on my inception-sound. Wav , created using lmms, again 2 instances of zynaddsubfx and now also 2 instances of sf2-player with a trumpet type sound. I also used lowpass filter.
I created this sound using lmms and 2 instances of it's zynaddsubfx plugin and a kick using the kicker plugin and some ladspa effects. I tried to emulate the "inception braaam " sound the best i could. Hopefully someone can find this useful to use in their project.
