A increasing target lock tone i generated for a personal project. It is rough and meant to be tweaked for your needs. Sound is supposed to emulate an electronic weapon lock sound.
I built a pad with several multiosc synths, this is me pressing one key on a midi controller and letting it go. There are approximately 48 separate oscillators stairstepped on this one. I think it might have completed one cycle.
A short loop i did with a sample from a moog minitaur. The sample was downloaded from modular samples here on free sound. The loop was created in metasynth.
4-bar-techno-loop made with rebirth. 143 bpm. Slightly improved with some dynamics. Before i provided a rebirth-mod with samples from thefreesoundproject.
A singing transformer. Ain't it a somewhat boring one? well, a transformer has found a few basic frequencies in the place he works, he made the best of it.
