It’s not in the manual yet unfortunately. How you do it depends on two things:
Do you want to automate a on/off signal (like mute) or a continuous signal (like volume)?
Do you want to perform the automation live (using a pedal, midi rotary encoder, etc.) or do you want to ‘draw’ it before the performance?
Automation in ALK always exists in its own track. So you will need to create an automation track. If you answered question 1 with ‘on/off’, you need a ‘command automation track’. Otherwise, you need a control automation track. Both of these tracks are created in the same way: you click on the ‘+’ button on the bottom-left of the screen.
If you want to perform your automation, you’ll need to define a source. Click the track leader or type ‘tt’ to make the track panel appear. Next click on the learn button, and follow the instructions that appear.
Next you will draw the automation region. In ALK all automation is associated with a time interval during which the automation is applied. Just as you can draw record/play loops with CMD/alt + mouse drags, you can do the same with performed/scripted automation.
Automation you perform is called captured automation and had a yellow outline. Automation that you draw ie script had a light blue outline. Once you have drawn the appropriate region, you route it to destination and either choose the value sent or draw the automation (for scripted control automation) by clicking on the small button which looks like a curve, which toggles between routing and curve drawing mode.
Let me know if you have any problems with this
