I'm having a bit of and issue trying to get the midi OUT function working,ive enabled midi output from the sonar wrapper and within the lfo tool but no matter what channel I've tried I cannot get any parameter of sonar or any plugin to respond,if anyone on here uses lfo tool and got this working please let me know.

Here is the process http://forum.cakewalk.com/FindPost/3269447
In your case though set 6 will need a virtual MIDI cable such as LoopBe or LoopMIDI as the MIDI output
You will also need to enable MIDI learn or Remote control for the parameter using LFO Tool MIDI data.

OH I SEE! I actually need to use a midi track and send the signal rom there? ok ill try that thanks!

Just an FYI - you can draw periodic MIDI automation waveforms in SONAR, and even change the slope and amplitude over time. See Week 21 in Friday's Tip of the Week.
