Why cant i fade in or out a midi clip

Yeah, please someone tell me how to fade in or out a midi clip.......i noticed i have no options in process effect, and as the sonar documentation tells me to just use the edit tool and click on the corner.......but it wont click on the corner...........and i went to cross fade a addictive drums loop with a loop from the loops browser....seems that wont work.....it just turns the browser loop into an addictive drum

Watch the video and and look on the Cakewalk Documents section of the cakewalk website.

You can add a volume automation envelope to the MIDI track, but it's actually better if you use a volume envelope on the audio track that the MIDI track is driving.
 
Peace

Thanx everyone for your input, yeah i think a volume automation is easiest.......Question what is a "cc ten event to be drawn in piano roll"?....and thanx chuck for ye helpful drum video...yeah you were the geazer that had the focusrite and mackie control surface i think from my earlier post, setting up hardware for my software.......Yeah i ended up buying the Zoom R24, i thought it was pretty craphouse, but i did like some loops, which i ripped off it(Good for camping away from home etc), so my studio i bought a presonus 1818 8 input soundcard and also a beringer UFX 1604 16 channel mixer/interface/transport...........So yeah, thanx to the sonar online forum im learning heaps really fast, cheers

Or if you wish to use controller 11 events to do the fade out, you can do do in PRV.  Start drawing your volume curve and before releasing the mouse button, hold down shift.  That way you will produce a linear reduction of volume from start to finish.

Ok so thanx all, excuse my newness, Using automation, i know how to manually, move the knobs in read/write mode,where everything lights up red that your automation......how do you set it to manually, for example go between point a and point b....say for example using the smooth pluggin, you want it on 3 position at the start but then 5 at bar 10 and then 8 at bar 15 etc?

The descriptions above showing how to create fades for MIDI give a clue about why the corner-grip fade is not offered on MIDI clips.
 
MIDI fades require using one of the publicly defined parameters, volume or expression. A person might think these ought to be controlled by CC (continuous controller), leading to a solution whereby Sonar just scales the parameter down to zero or up from zero for fade-out or -in based on the user's desired set value. Unfortunately it is not always possible for Sonar to know the user's set value. It could be hidden in a synth preset or a sysex message, instead of being set in a MIDI CC or envelope that Sonar can follow. Therefore it is left to the user to decide how to use the CCs.
 
Audio fades do not require using any publicly defined parameter. Sonar can just scale audio samples between 0% and 100% to compute fades, and offer a choice of curves as well.
