Sonar X1 and GPO 4

I had not on my music PC. But on my Vista machine last night I noticed that when I was previewing midi clips with Session Drummer 3, the first part of the clip was loud then it dropped in volume like your talking about.

Don't know if it's related, but thought I would post and see what happens.

I am sorry, I can't remember exactly where in the preferences it is located but there is a toggle to enable a track to search back for any controller data before it resumes play. You can uncheck that box and it will disregard the last controller command. I had trouble with GPO4 going silent because Sonar was searching back thru the midi track resetting the volume to zero.

I think it's the "Zero controllers on playback" option, or similar, under the Project section of the Preferences dialog.  It took me a while to get used to this after I started using GPO.  
 

We've all been there!

 
I haven't. I have GPO4 and was thinking about using it this week. I have X1E, a midi keyboard controller, and an Octa-Capture. I have never quite understood midi and have really have only worked with audio recording. It is running into things like this when I try that discourages me.
Can someone perhaps give a readers digest version of what to do to record using GPO4 and make it a "for dummies" version, I mean assume I don't know anything.
 
I got this from the "internets" but I don't know how or why I would use it:
 
Controller events
In MIDI, adjustable parameters for each of the 16 possible MIDI channels may be set with the Control Change message, which has a Control Number parameter and a Control Value parameter. GM also specifies which operations should be performed by multiple Control Numbers:
[font=""]1 Modulation wheel
6 Data Entry MSB
7 Volume
10 Pan
11 Expression
38 Data Entry LSB
64 [color=#0645ad font=""]Sustain[font=""] pedal
91 Reverb level
92 Tremolo level
93 Chorus level
94 Celeste level
95 Phaser level
98 Non-registered Parameter LSB
99 Non-registered Parameter MSB
100 Registered Parameter Number LSB
101 Registered Parameter Number MSB
121 All controllers off
123 All notes off

 
I see that CC 1 is the mod wheel and CC 11 is expression which I would need using GPO4 but I don't know how I would enable them and I wonder if CC 11 is related to aftertouch maybe??
 
Thanks for any help before I try it and run into a wall. Are these used to assign functions to sliders and knobs?

Thanks grumbleweed, I don't know how to mark this post as useful but if I did I would. I will use the manual.

A trick I've used with Garritan JABB, which uses CC1 the same way in Aria Player, is to copy MIDI velocities to a CC1 lane in the controllers pane of the PRV so each note has its initial volume set according to velocity. If you record MIDI in real-time from a keyboard and are used to controlling dynamics with velocity, this can be very helpful.

copy MIDI velocities to a CC1 lane in the controllers pane of the PRV

Very good idea! How do you do that though? Can you drag n drop? (how would you select the MIDI velocities?) Use the "select" filter? (to select cc7 messages the "paste" in the other lane?)

Cool! I'll try that... ;-)
