Here’s an example preset, @kamal, with two Delay pipes, side by side both with Delay Time mapped.
kamal_vm_limit.mhp
The first is mapped directly to the CC coming in MIDI-A:
see how the values 116 & 127 give times of 8bars & 16bars.
In the second version the pipe is mapped to Virtual H allowing us to modify the mapping values.
Now, although we see the same CC values in the Monitor…
..the values have been rescaled in pipeline 1 to restrict them to the values you want for the mapping:
Try setting different values in the Rescale pipe to see the different outcomes (You’ll notice I’ve restricted the Out Low range as an example)
Then maybe try used two to Rescale pipes scale down, scale up to get only some of the Delay Time values (say 1bar, 1/2, 1/4, etc)
PS.
Notice the Virtual-H pipe goes nowhere in this example.
That’s because I’m only using it to create the mapping.
Conversely, I could happily Filter out the CC from pipeline 2 and it would not affect the Delay.
(I only left it in to show in the MIDI Monitor 
)
