I was a whiz on the Roland W-30..and i sold the Ensoniq ESQ-1 ( worked in music retail as well of and on) All those keyboard sequencers were pretty tedious I must say! And the hardware based sequencers as well...I had MIDI workshops in my home and taught folks how to use ti all...Before I used the Atari ST, I actually sequenced on a Korg M1. It was tedious, but it worked.
It was fun!
