But it's only 5 minutes if it's consecutive recording, right? I can record multiple parts across the same track.
Yes, you can record multiple parts.
The big limitation on samples is ultimately RAM. Disc streaming takes the sting out of this on the Force, but the MPC line doesn't have this (yet).
If you were to go with the Force, I would in your position record elements of the song as samples perhaps 4 to 16 seconds long, and then lace them together that way. I've done similar things myself, and it works pretty well. It also means that if you suddenly feel the urge to go for another round of the chorus, it's a simple row launch away. However, for what you say your aim is I would almost combine something like the MPC One with an MTR such as the Tascam DP-24SD or DP-32SD. An MTR will be friendlier on jobs like comping and overdubs in a way that the MPC workflow is not.
In the sense of a workstation, which is a term that arose with devices like the M1 because they allowed someone to do on a single machine what had previously only been possible at an audio production station with tape cutting, multitrack reel-to-reel recorders, a big analogue mixer, outboard effects and so on, the MPC family and Force are both workstations, but they are workstations with a particular focus; that of assembling songs from disparate parts. On the other hand, the modern MPCs also allow you to have a linear experience if you simply put your whole song into a single pattern.
The question is whether or not that will give you what you want. If you want to have deep multitracking, layered vocals, all sorts of cross-fading and overdubbing, then I would go for the MTR as part of the package. If you're happy to lay down the MIDI, record some verses, slap them down with sample playback and work on that basis, Akai has what you need.
