I agree. It seems sometimes that people who haven’t used an MPC bash it for its relatively more complex workflow compared to the more limited Digitakt, but the reality is that it’s very immediate and encourages you to use your ear, ‘play’ your notes live using Dub Record and ‘feel’ the groove - as opposed to programming it on the DT and being delightfully surprised when making a programming mistake (I love the DT for that, for the record!).
That last part is definitely an attraction for me, its portability. But “all the musical features of the MPC” is too much of a stretch for me. You lack all of the amazing synths so you can forget about basslines, pad chords, arps, lead melodies etc unless you’re prepared to go really deep with sampling other people’s music and/or carefully overdub and resample a pattern until you’ve created your chords or melodies. That part seem like an even more complex task than programming in chords on the Digitone and it makes me wonder if it’s even possible to create certain genres of music on the SP-404. It seems it can be acceptable for heavy samples based hip hop type of music, but for anything close to synth based electronic music, it’s a rather crippled experience where the MPC is heads and shoulders above it. My 2 cents here obviously.
