This set of videos, via Carlos Serafini, capture a laid-back micronal synth jam on a hexagonal control keyboard, Autumnal Modulations.
Here’s what Serafini has to say about the piece:
This song is both the first one I compose employing extensive modulations (with Carlos Gamma tuning system) and the first one completely transnotated.
Transnotation allows me to analyze my own compositions. To demonstrate that, I have recorded 2 short movies where I perform the “lead guitar” part of portions of the original tune while listening to the pre-recorded “bass” and drums parts and reading my transnotated score.
This guitar sound by Spectrasonics Omnisphere has already been featured on many songs of mine. I love it!
See Serafini’s site for details on the piece and his setup.
