Anyone can make music,certainly with a Groovebox,it's still what you put in,though. GIGO still applies.
The immediacy of twisting a knob,changing a pattern, adding your own notes to an exsisting pattern,thereby changing it to something comepletely different,creating and programming new patterns,or having different combinations of Grooveboxes,Software and Hardware, it all makes for an addictive experience.I'll always record everything into the PC,because you do hit upon something very special very frequently,which then is a fantastic base for a new track. It liberates you from sitting down and staring at an empty sequencer screen for a while while you try and think up a creative way to start your next track. I find making remixes with a Groovebox and Ableton Live inspiring, makes for a fantastic Mashup too. Record a few samples from your favorite track,especially the parts where you just hear acapella voice material, transfer them to a KORG ES-1,create a skeleton of a dance track in Ableton, and, as you slowly build your track,start twisting knobs, creating  repeating echo's in time with the beats,as all the KORG grooveboxes, the ES-1 is especially good in flanging,repetetive echo's,slowly fading, mellow sounds or fast,metallic crunching grungy sounds,great for innovative creative dance tracks.My absolute favourite is BT, who has managed to crossover from Trance to Rock to Pop,using this way of working,i do like Underworld and The Crystal Method too.
And just read any of the interviews on the Korg ER1 and EA1 websites,to see how Pro's are using them.
I certainly prefer it to working with samples,as samples are more static and rigid to me(although Ableton Live certainly liberated that way of working too). Experimenting with sound is very inspiring,and the Grooveboxes are the ultimate inspiration for me.
