Well according to a quote from Steve on his "Timeline" that is located on his Website (http://www.vitalinformation.com/steve/index.htm
"I recorded my first album, 'Enigmatic Ocean,' with Ponty, Darryl Steurmer and Allan Holdsworth, guitars, and Ralphe Armstrong, bass. That same year, I recorded an album with the Dutch band Focus
. I also started endorsing Sonor Drums."
So I guess the answer is yes.
Of course that was in 1977 and as you can see that was a VERY GOOD year for him.
