ghyabri ji It depends which version you're using. When it comes to Imageline, they upgrade their product every now and then. The lastest one so far is FL Studio 6. I'm familiar since version 4 and I have no idea before that, I guess pretty primitive.So if you have anything after 4, it's pretty straigh forward. You can automate anything, any button knobs internally or externally. You draw internally and for external, you use a controller (anything with knobs, faders like a midi keyboard or just straight controller). So the Pitch.... Internal (if you don't have a controller, keyboard). 1. Open up the generator, the one you want to change the pitch. 2.Right click the pitch (it's at the top) 3. Edit Event 4. Now draw with the pencil (you get at the top of that window). Make sure draw where you want it on the timeline by selecting it first (the top of the timeline becomes pink??) 5.Fool around that screen since it has lots to offer. External (Keyboard with knobs, fader or any other external controller) 1. Open up the device you wan to tweak 2.Select any knobs (including PITCH if you want) that you want to tweak 3.Right click , go to "Link to controller" 4. Move any fader, knob on your keyboard. This will automatically link them. 5.Repeat this for any number of controls you want to. It'll all depend how many knobs you have with your keyboard. The more, the better. Keyboard controllers are cheap these days. You can then tweak lots of the parameters in live use. I hope that help. Let me know if you figure it out. I can point towards some site with further tips if you want to. I'll have to be at home for that.
