Re: Synthmania
Jupiter-8, LinnDrum, Pro-One '80s Sequencing 
Message from the author: "After the '70s "POD", I'm making an '80s pod in the studio. Next, the '90s pod. The LinnDrum triggers the Pro-One's sequencer. The JP-8 plays chords (a Garfield synchronizer syncs the Linn-Drum to the Pro-One)". And I will add from myself that the video turned out to be cool, the melody is very pleasant (that's why I posted it here), & Jupiter-8 is a really fantastic synthesizer that looks great!
