I love knob twiddlin'. This song is a good example of that.
I did "Steem Machine" a few years back when I was using Cubase. I used a number of software syths for this. It has been so long ago I can't recall the names.
If anyone would like take this and play over it, remix, mashup, slide and dice, have at it!!
I hope you enjoy :)
