Ambient Electronic Music, "Sleep Sweet"
I decided to take advantage of the holiday weekend and make another ambient synth tune while my wife was sleeping. I was very pleased with how well this one came together. It was influenced by the peaceful music of C418's Minecraft soundtracks.
I used four Fugue Machine sequences to trigger four different synths in Korg Gadget. Most of the synths are polyphonic and play all of the note of the four sequences. However, I included one monophonic synth with a moderate about of portamento which glides with the sequence as if it's getting snagged by each new note.
The audio from Korg Gadget was recorded live into Ableton Live Lite. Inside of Ableton, I processed the sound with three auto filters routed in parallel using an Audio Effect Rack. The three filters (one LP, one BP, and one HP) were all modulated with an LFO at different rates which would cause the filters to drift apart over time, adding three additional layers of movement to the music at different frequencies. The BP and HP channels each received different levels of delay.
The whole processes of making this track took only about two hours.
