LOL. For some reason when I posted the first one it didn't refresh on the last page so thought it had lost it. So I reposted and it's almost exact copy. This hardly ever happens. Usually I can't remember exactly what was in my head. :-D
Just watched other video. I wonder why the ST has no HD like the Akai. Or indeed why Cubase isn't on a ROM card. The ST supported ROM expansions. Makes sense to me for the time.
Around that time in late '90's I had an Amiga A500 with an A590 HD. But with no MIDI ports or a keyboard I could only make funny sounding techno and not any "real" songs. :-)
