The stock tb303 does only respond to accent on or off.
Most MIDI controlled 303s (such as my MIDIBass interface) use a threshold on
the velocity level to trigger accent.
If it weren't quite so complex electronically, it would be sweet to have an
increasing velocity above the threshold level able to increase the accent
knob setting on a 303.

I would think varying destinations of accent would be simpler as a function
of the receiving synth.
If you had a voltage comparator & switching module, you could use varying
levels of velocity CV to alter different aspects of a patch depending on
accent level.
With Cirklon CVIO and P3 pattern, you can easily control 4 other CV
parameters with the auxes, on top of the note and velocity CVs per step.

You can control the slide time per step on a CVIO output using an aux
assigned to a CC.
There's a choice of expo or linear slide on the outputs, though that isn't
under sequencer control yet.
I've got another slide mode or two to add when I've got time.
The first would be a constant time linear slide.
That involves dynamically altering the linear slide rate so that slide
between consecutive notes always takes the same time.
IIRC the OSCar did this.
