Week 7 Audio Arts - Analog Synthesizers!

Above is a Roland SH-5 which I attempted to create some organic sounds with. It feels great to be playing with something that isn't a computer. The many controls allow easy realtime control to manually add that modulation you need without bothering to assign things to an LFO or modwheel. I used the pitch lever often to control pitch or filter in order to move it exactly as I needed. 


I found it quite surprising that it isn't too hard at all to obtain a few reasonably organic sounds, though I ran out of inspiration quickly.

The wind was created by filtering white noise with the LP and BP and I added in a slight whistle created by ring modulating the oscillators together.

I think I did the bird noises by increasing the resonance of the filter till it self oscillated. I then set up a suitable envelope and swept the filter with the pitch stick while playing notes.

Other sounds are fairly obvious! The white noise oscillator makes it all possible because otherwise we could only do pitched sounds.
