This all assumes bump wants to play in 32nd or 64th notes, as opposed to 16th notes. Unquantized != faster. I’m pretty sure the AR will allow unquantized recording, as on the OT and A4, with deviations from the quantization grid being available through micro-timing (so it’s not totally, truly unquantized, but quantized to 1/384th of a beat which is fine enough that nobody will ever hear the difference unless your track is at 25bpm or something).
Now, for 32/64 note percussion that’s going to need track multipliers. Bump, grab the Analog Four manual from the Elektron site and look up the ‘scale’ feature; basically, on any given track you can have up to 4 bars with up to 16 notes per bar; if you want more, you trade off higher resolution for shorter pattern length, eg you can get 2 bars of 32nd notes or 1 bar of 64th notes. If you want very fast percussion that is completely unquantized, this is the way to go.
However, on the AR you will also have access to a note retrigger function, which rapidly retriggers hits at quantized intervals. This is great for things like snare rolls or rapid ticky closed hat sounds, as well as strange special effects. Using note retrigger you can get multiple hits on any given 16th note step without changing the pattern scale. So you might have some rhythm like
t t t t t t ttttttttt t t t t t ttttttt t t
going in the background using quantized notes + note retrigger, and then have really loose kicks, snares and ??? going on in front of it, like the Trap music style. I’m not into Trap but there are some tracks with crazy good perscussion out there:
You could totally do this with the Analog Rytm (or the Octatrack for that matter).
