Melodyne comes in four different editions, the smallest being Melodyne essential and the largest Melodyne studio. All of them use the same algorithms and tone generation technology; they differ only in the range of functions offered. All editions share the following features:
All editions are compatible with one other: A project begun in Melodyne essential can be opened later in Melodyne studio and edited using the larger function set of the more powerful edition. By the same token, a project edited using Melodyne studio can be opened and played back in Melodyne essential with all the earlier edits faithfully reproduced. However, if you wish to do any further editing there, it will be using the more limited function set of Melodyne essential.
