That is true, but a good workaround is to record the Flamenco onto your computer, and use an audio editor to slow the wav. file down (Time stretch). Try slowing down the part by 50% at first. Then you could use the Audio-to-MIDI converter, then simply double the MIDI playback tempo. If you don't have an audio editor, there are plenty of cheap, and free ones available. Remember to , that you don't need stellar time stretching algorithams that perfectly translate every nuance of the audio data. just something to convert the majority of the notes accurately. You can always fine tune the MIDI data afterwards.
