Though new MIDI tracks appear to have default values for continuous controller playlists, this is actually not the case. For example, when viewing a MIDI track’s Mod Wheel playlist, you’ll see that the breakpoint line is set to a default of zero. However, since the modulation wheel on your MIDI controller may be purposely set to a different value, the default value in the track is not transmitted when playing.
For example, if you record Mod Wheel automation that changes from 0–90 towards the end of the track, and you then play from the beginning of the track, or from anywhere before the change, having the Mod Wheel value remains at 90 until the 0 value is reached is not likely to be what you want.
To ensure that the default controller value for a playlist is sent (and chased), click the initial breakpoint at the beginning of the track, move it slightly, and set it back to the default value.
