change_cutoff_attack()

This function can be used to modify the filter cutoff attack time of active voices of a particular note. In contrast to other synthesis parameter related functions, this function only allows to change the attack time when the respective note is new, that is either i.e. at the beginning of a note event handler or right after calling play_note(). So you should perform the attack value change as soon as possible, especially before calling any wait() function and before entering a loop which might take a long time to execute (which might cause your script to get forcely suspended by the script engine due to real-time constraints).

The attack time changes set by calling this function are always applied relatively to the attack time calculated by the synthesis model and sampler format. That means the various sources of attack factors like MIDI CCs and other attack parameter factors that may be defined by the instrument patch, are always processed and calculated for the voices first, and the final attack time applied is always a relative combination of all those factors and the one set with this function call. Or in other words: you cannot replace the attack set by other synthesis sources with this function.

Release Trigger Samples: In case the affected voices cause release trigger samples to be spawned later on, the attack time of those release trigger voices will not be affected by this function at all. So if you need to control the attack time of release trigger samples by script, then you might rather also trigger those release trigger samples by script with play_note() instead of using the sampler format's internal support for release trigger samples.
