I use Fl studio, and 'Edison' its audio editing plugin can't edit more than one audio file simultaneously. Software like 'Audacity' can do multi-track editing but audacity can't be used as an external plugin in other DAWS. Is there any vst that will do the job of Audacity, since I still want to use Fl studio as my platform?
You can accomplish this by using the "playlist" where all of the tracks are assembled to form the timeline of the song. Simply load all of your audio files and even midi onto it and you can slice, arrange, add automation and all of the effects you could desire to them.
Hope this helps, let me know if you need more!
You see,a single instance of 'Edison' in FL Studio is not meant for multitrack audio editing. I guess, you want a sequencer where you can edit multiple tracks simultaneously. The 'Playlist' in FL Studio, sequences (plays) all elements of the project to make the final song. The Playlist window is a stack of multi-purpose 'Clip Tracks' that can hold Patterns Clips, Audio Clips and Automation Clips.
