This video tutorial explains how to automate all synth parameters in Sonar 8, including parameters you cannot edit with the envelopes! This took me a long time to figure out, so I hope you find it useful. Be sure to check out the serious-sounds.net music production community, and feel free to visit my website danielbyer.com though that's a work in progress so don't expect much yet ;)
Depending on the response, I may produce more video tutorials. Enjoy!
