Sunday Synth Jam: Skoulaman created this live Berlin School/space music/ambient synthesizer jam.

Details via skoulaman:

Sequenced with an arpeggiator loop from the Kurzweil Midiboard connected with the Kawai k1r and the Waldorf micro Q. The solo vibe sounds are from a Yamaha CX5M computer and the Korg Lamda in combination with a Moogerfooger. Accords played om the Juno 106 and on the Korg Lamda.

Sunday Synth Jam: Retrosound created this ambient soundscape, Sound Clouds, to showcase the Kawai K5000R.

The track transcends the goal of being a demo of the Kawai K5000R, though, to be a lovely ambient soundscape synth jam.
