As @sezare56 said, you don’t have to stop the sequencer to play back a sample.
I’ve accomplished this two ways, one with pickup machines, the other with flex machines.
As an aside, @thoughtstarZ, keep in mind the the track recorders are separate from the tracks.
*no matter how you have the 8 audio tracks configured the 8 track recorders are always available.
Load flex machines to tracks 1-4. Assign track recorder one to all four tracks. Now when track recorder one samples anything, that audio ends up in audio tracks 1-4.
Sample anything, just to fill the track recorder 1 buffer.
Now push track 2 select + Bank/Edit, and slice it to like 16; repeat this procedure for tracks 3&4, but change the order of the slices with random locks, or reverse playback or change the number of slices, whatever you want to experiment with.
Now sample something else into track recorder 1, and all of a sudden, it’s in all four tracks ready to manipulate the same just recorded sample with the settings you chose.
To automate this, put a 1-shot trig on the first step of track 1… Put regular playback trigs on the first step of tracks 1-4.
*EDIT: to get the Linear Locks or Random Locks working ( as expected ), you’ll have to put more than 1 playback trig on the track… try filling it with as many trigs as slices you chose.

Hit play on the sequencer.
You should hear the audio you sampled in to create the slice grids for tracks 2-4, along with the sample from track 1, playing back from the playback trigs.
NOW, sample something new into recorder buffer 1/track recorder 1 by hitting track select + Yes. This will arm the 1-shot trig so it samples ( refills record buffer 1 / track recorder 1 ) on the next pass;
the other 3 tracks will playback this audio however you specified.
Track 2 could be your machine gun sixteenths, track 3 could be the reverse of the sample…
Hopefully this helps.
