I recently tried sequencing some instrument parts by playing my
keyboard controller along with a CD recording. It turned out to be
impractical because I was unable to get the tempo of the sequencer to
stay exactly matched to the tempo of the recording, so the notes I
played drifted out of phase with respect to the bars of the MIDI
sequence. This was especially problematic when there were tempo
changes within the recording.
My question: Are there sequencer programs that allow one to record a
melody line in real time at an arbitrary tempo (i.e., ignoring the
sequencer metronome) and then manually stretch or compress the entire
track, or portions of a track, so as to re-establish the correct
relationship between notes, beats, and measures in the final sequence?
Alternatively, is there a mechanism for leaving the speed of the
recorded melody alone but telling the sequencer after the fact (e.g.,
by hitting a key in time as the melody plays back) where the beats in
each measure fall? Seems like it ought to be an easy and obvious
feature to implement, but I've never found anything like it in either
PowerTracks Pro or Freestyle.
