I know the "no bloody computer" feel, it's a returning crisis peak in a musician's life. Been through it more than once.
So one gets a MIDI workstation or groovebox instead (which is a Windows computer too, BTW, it just doesn't tell you), then a second, than hooks the two together one day, then gets a computer eventually anyway to record them, then before you know suddenly Ableton is back... that's life.
Or, I heard they now sell some thingus called Electronic Octatruckulator... supposedly that's not a computer at all, it's powered by tamed hamsters inside.
Well, there is always the acoustic guitar (or ukulele) and singing...
