Most of the works in Volume 1 have no drum machine (hardware), or quantization, since either it wasn't the aesthetic- or it was created early on before auto-edged-looping became as easy as taking as sitting in a chair. Although it might be possible to "miss" the chair, its really NOT that tough to sit in one, and that is where most software (and a lot of hardware) have gone. I feel it diminishes the wonder in searching for sound edges, and the way sounds interact. Its like buying pre-cut, pre measured meals and cooking them according to a recipe. It just seems to be too easy to churn that stuff out. Rant over. Although a few use samples of percussion and a few early loops.
The music on this album was pieced together entirely from pre-existing works, there was never a "flow" between them (except for ElectricIxtalan), often created at different times with differing levels of technology. You will probably hear the difference in the recordings as well.
My fascination with electronic sounds was quite accidental. In my early teens, I was often playing around with friends recording us (creating a comical fake radio station, doing interviews, etc) and creating sound effects, using records, and playing with their speeds. Using the pause button to create hilarious effects while speaking. Eventually I got my hands on a reel to reel, thanks to a family friend, and was unendingly fascinated with recording things and touching the reels to see what happens to the sounds as I record it. Eventually that became more of an obsession through college, and after. Gear lust is hard to overcome, and I was no stranger to this- although I had no money. A lot of the gear I had was either free, donated, or I bought very cheap used. The few pieces I bought new were a prized Roland V-Synth (first gen), and an early Korg KOASS Mixer (a bit different than just the pad), along with some recording hardware from MOTU.
So most everything you hear comes from that environment over the years. I recorded, designed, edited, performed, etc, everything (primarily due to lack of funds), and it taught me a lot about what NOT to do.
