I like both logos, and I have one synth with each... an older OB-6 module with the DSI & T.O. logos and a Take 5 with the Sequential logo.
I put up an avatar on my profile which I created from the original poster image from the Sequential site, and I have both names on there.
Dave's contributions to electronic music have touched virtually everyone on the planet, as I'm sure anyone who has ever listened to the radio, especially in the 80s, has heard a Prophet 5 at least.
Rest in much deserved peace Dave Smith. I hope you're sharing a toast with Bob Moog, Don Buchla, and Alan Pearlman and making lovely synth music in the afterlife.
