This synthesis tutorial, Alesis Andromeda Atonal Synthesis, is pretty strange, but it’s full of great sounds and interesting information.

This instructional video explores atonal synthesis using the amazing Alesis Andromeda analogue synthesizer.

We can investigate atonal applications for sound synthesis and with some background theory, understand how to create ambient pads and ringing atmospherics and similar sonic combinations. Analogue synthesis can create atonal and ringing timbres that can be played to bring about dissonance and clangourous combinations that can be used to create atonal musical sequences and special effects including background atmospherics and pads.
