[SOLVED]MIDI Question: Is there a midi or CC command that amounts to "ramp from X to Y?"

I'm not sure what you mean by ramp from x to y.

MIDI is a highly granular description of how an instrument is to respond. You can send a command to increase volume by a certain amount, but to increase it by the next gradation, you need to send another message. Think of it like the operators in mathematics, each individual operation is quite limited in terms of what it does, but by combining them into equations you can describe very complicated relationships. Unfortunately the equations do not exist within the set of operators, they must be supplied from the outside. What provides the "equations" for MIDI is the MIDI file which can send a couple of dozen increase volume messages sequentially to do the ramping. Creating that complex file from simple MIDI commands is the job of the sequencer, or controller. Sonar can certainly create a ramp up of many MIDI messages that will give you the effect you want.

You can draw a controller from one point to another for any controller in SONAR.

To answer the original question, no, there is no CC in the standard MIDI definition that triggers a gradual change.
 
Specific devices (perhaps lighting systems, for example) might implement nonstandard controllers, but those would be specific to one product. For the most part, a CC conveys one static value at a time, so gradual changes must be implemented by sending a sequence of discrete CC values of progressively larger or smaller values. Fortunately, SONAR makes that easy to do.
 
Ramping, whether you're talking about volume or pitch or modulation or filtering, is accomplished through MIDI automation. An automation envelope may look like a solid line in the track view, but you're actually telling the DAW to send a series of CC values that gradually go from one starting value to another ending value.
 
I'm at SONAR 8.5, so it might look different nowadays, but I right-click on a MIDI track and select Envelopes -> Create Track Envelope -> MIDI from the context menu. That presents a dialog box where you enter the CC number. The default envelope that's created can then be broken up into segments and various line shapes can be applied to describe exactly how the CC values should morph (ramp). 

Thanks for all the great replies.
Thank you bitflipper  for just answering the question directly,
I get it now.
Trying to voice automate during recording cause I'm alone(Saxophone).
Thanks again to all,
