From Pro Tools Expert : Avid, makers of Pro Tools have applied for a patent based on a very interesting concept. check this Systems that enable a user to record music for playback or for producing musical notation require that a tempo and a time signature for the music be supplied before the user can start recording. Once the user starts recording, he is constrained to play in time to a metronome click. This is an impediment to recording new ideas, as decisions about changes in tempo and time signature have to be made in advance and the user is unable to introduce timing variations that are a natural part of a performance. If the user opts to turn off the metronome click, he can record in an unconstrained manner, but the recording system is unable to interpret the musical data for quantization or displaying notation because the input is not aligned with an internal tempo map. The requirement to pre-select a time signature and tempo is particularly difficult for less experienced users, who may not be familiar with music theory or even with musical notation. There is therefore a need for musical input systems that free users of this constraint A free rhythm musical input system enables a user to record in a natural manner by not requiring the user to make decisions about tempo or time signatures. It also removes the constraint of playing at a constant tempo that follows a metronome click. In such a system, the user is able to indicate to the system that he is ready to start recording, e.g., by hitting a record button, and take his time to prepare this thoughts, at which time he can start playing in an expressive manner The system then interprets what the user plays to infer the locations of the measures and beats, and the corresponding tempos and time signatures that best represent the musical intentions of the use In the system described above, the free rhythm music is received in the form of a sequence of MIDI events, in which the temporal locations of the notes and their duration are provided explicitly. It may also be possible to receive the music in audio form, and use audio analysis tools to determine the temporal locations of the note onsets and, in some cases, also the durations of the notes within the audio, thus broadening the applicability of the described techniques to acoustic performances or recordings..” So a recording system that knows where you put the bars so you just play in freestyle and it conforms the program to you !!
