Composing using MIDI effects goes far beyond just generating some random notes. There are all sorts of things you can do with Arpeggiator, Scale, Note Length, etc. However, as mentioned yesterday, you often end up in a situation where you want to keep some but not all of the material that gets generated. In some cases, sampling the audio doesn’t do the trick – you need to do a few manual tweaks to the MIDI to get the part just right. In this case what you need to do is record the output of your MIDI effects into a new clip so you can edit to your heart’s content.
Try setting things up like this:
The track called New MIDI Clip is configured to capture the MIDI coming out of the devices in the first track. Just check out the MIDI From menus in the second track – these are telling you that the new clip will record the output of the track called Crazy MIDI FX Stuff, Post FX – after the MIDI devices have processed the signal.
Once you’ve recorded a new clip into this track, you can simply copy it into track one and disable all of the crazy MIDI effects. (Remember, you don’t need them anymore since you’ve captured everything they are generating into this new clip).
