Hi Stephen. If you load a 'universal mode' matrix and open the VI's Control Edit window, you'll see that the horizontal rows are controlled by playing speed and the vertical rows by CC1 (mod wheel). Playing speed is determined by how quickly one note follows another - if you play faster (or increase the playback tempo of your track) the switching will behave differently. There is no control data for playing speed other than the elapsed time between notes.
Mod wheel movements are transmitted by your keyboard as MIDI Control Change (CC) data, a continuous steam of numbers. If you use the mod wheel while recording MIDI you should be able to subsequently see these CC1 numbers in your sequencer track along with the notes you played (in Logic you have to open the Event List to see them). Sometimes sequencers filter out the display of CC data so as not to scare the user - whether you can see it or not, this data is there embedded in your sequence.
Any MIDI data can be copied from one track to another using cut and paste. If you grab a MIDI 'region' (or whatever it's called in your sequencer) and assign it to another instrument, all the control information will be copied too.
Apologies if any of the above is stating the blindingly obvious!
