Yep, Groove is the medium one. I was taking the names from Amazon but I think NI just calls them Mikro, Maschine and Studio.
I've used old hardware sequencers and drum machines, synths, sound modules, samplers, and keyboards for recording but never used modern hardware for recording. All my recording has been via a keyboard and usual DAW editors and instruments.
So many people seem to think these pad things are the best music-making gear ever. When they first appeared, no offence intended, but I thought they appealed to people who couldn't read or play - music by numbers sort of thing - and I couldn't see the point.
However, trying to be open minded about it
and these are still getting rave reviews from many people so I am tempted by NI's offer to give it a shot
and get a good set of instruments into the bargain.
Having said all that, I think the S keyboard would be a better controller then the TI.
Oh, decisions, decisions...
