Higher values will enable you to zoom in closer on notes and draw smaller ones more accurately, as well as being able to adjust the start and end points of the notes to a finer resolution. You can also hold down CTRL while adjusting knobs to get more granular control, and exact values (i.e. To set the resolution of FL Studio's sequencer, select the project's General settings from the main Options menu and change the Timebase (PPQ) value. Then edit the automation clip that resulted, so the change is as abrupt as you need it, while being careful to not to change the start or end values. This affords you a lot of flexibility when it comes to adjusting note properties and can be very useful when a number of notes are too loud or too soft and you want to make them fit better without sacrificing their relative levels. They are part of a larger group of features in FL Studio and many other DAWs that are formally known as internal controllers.
An automation clip (or envelope) can automatically control the behavior of a parameter or group of parameters in FL Studio. In the piano roll, the velocity levels or other parameters of the currently selected notes can be scaled by pressing Alt+X. FL Studio automation can be achieved by a number of different methods. To the right of these knobs, the Timestretch knob can be used to adjust the clip's timing and length. In the Channel Settings window of the automation clip, the MIN and MAX knobs at the top will adjust the range of the automation clip. Automation clips can have their minimum and maximum values scaled, enabling you to edit the depth of the automation without going through and tweaking each point in the clip.
