Went on vacation at my parents place last week. Only brought an Model:Samples, a battery pack and a headphone.
Honestly I only did music for myself making beats and patterns and arranging them live but the only limitations I felt was in the number of tracks (played a lot with sample locking with drums), the fact I can’t sample directly from the M:S and the fact you can’t trigger chromatically and benefit from velocity which is annoying if you want to do something live.
I think a 2 grooveboxes setup, one sample based, one synth based, a mixer and a microphone and optionnally a midi keyboard is all I really need and want to produce music.
All this to say I probably just need a DN+DT or Novation Circuit Tracks+Rythm combo or a Deluge and I would be a happy man.
