Blipper is a skill-substitution for the 2nd scenario

I suppose I envisioned this working similarly to a car with paddle shifters in which a vehicle can be upshifted or downshifted at will, regardless of throttle/pedal position and without being required to roll off (except for scenarios that would force and engine to surpass RPM redline). A rev-matching "blip" naturally wouldn't be required in an acceleration situation, but it would be advantageous to have the option for seamless, clutchless downshifts in this application.

Quickshifter will work as you describe...no need for a blip...Cars dont blip....

With the way the Motorcycle manufacturers are embracing technology, I think we'll see seamless shifting, both up and down pretty soon.

Cheers.

Correct. Conventional automatics do not require blipping since the torque converter can smooth out downshifts; however, direct sequential and dual-clutch transmissions often do utilize auto-rev matching functionality.

Since we’re dealing with a manual transmission that is essentially taking on automatic transmission characteristics, I imagine downshift rev-matching under any scenario would be supported –not just when the throttle is completely closed. If the blipper is enabled only when the throttle is completely closed as some have confirmed, then this would imply the throttle should be completely closed in an acceleration downshift scenario, which seems counter-intuitive.

When I read a review on the 1299 it explicitly stated " you can change gears with out letting off the throttle"..

Maybe Ducati would frown upon you operating it this way..but the person doing the review seemed quite fine with doing it.

That's the point of the DQS..But that's what being debated....

This particular magazine statement may have been in reference to upshifts. Motorcycle-usa reported that sensors mounted on both the shift drum and throttle are used to determine when auto-blip is enabled. If true, this would lend credence to the assumption that quick-shift will not function seamlessly in a kick-down, acceleration scenario. If this is the case, it seems possible that a rider could mistakenly assume quick-shift accounts for this scenario and force a power downshift, which of course would subject the transmission to much higher stresses than those which would be produced from a traditional downshift.

How about upshifts with this auto upshift system? (Not asking about blipper function)
Say starting in neutral, then can you just go in to first with no clutch/throttle and ride of with throttle?
Or is it normal clutch in, change into first, throttle/letting out clutch for starting from neutral into first?

Hope this makes sense

You still use the clutch from a stop.
