Under Help menu there is a Browse the Manual option (or use Fn1) it has this section:
Playing Notes into Denemo - Audio (Souncard Mic Input) Denemo can listen for, and detect the pitch of notes on the mic input of the computer; it doesn't attempt to guess the rhythm - such systems do not work well - but you will find that playing the notes in time will help you to play them in, as well as make playing them in a musical experience rather than a chore. Playing the notes in can be much quicker than using the keyboard since the note octave and accidental are all given just by playing the note. If you are able to play a musical instrument then this will probably be much faster for you than typing note names, octave shifts and accidentals at the computer keyboard. Using the headphones out of an electronic keyboard avoids "noises-off" interfering with the pitch detection. Many microphones and pickups benefit from some pre-amplification - it is worth getting the level right before you begin. When you select the Input->Audio on the Main Menu the Pitch Recognition window pops up. While the mouse pointer is inside the score drawing area the score is sensitive to pitches heard via the microphone input. The background colour of the score changes to show that the notes will be entered into the score. There are two ways of using the pitch entry - Overlay mode (default) and Insert mode. The button marked Insert causes notes to be entered into the current measure in the prevailing rhythm - the mode is set to Insert for this. The button marked Overlays overlays the notes already present with the pitches you sound. There is a third button, marked Tuning, which is a state-of-the art musical instrument tuner. Music is entered into the measure which holds the cursor. If you are overlaying a rhythm already entered, then the first un-overlayed note in the measure is overlayed by the note detected. You can delete the overlay using the regular delete keys, or clear them altogether if you want to start over in a measure. If you are in Insert mode then the notes detected will be inserted at the cursor position. Use the enharmonic shift to select whether Bb or A# should be entered when you enter the given pitch - you can usefully go as far as B# and Fb. Use the transpose control to shift up or down by octaves. Most of the other settings would require study of the Aubio documentation to understand, but the one marked threshold may be useful to make the detection less sensitive to ambient noises if using a microphone with an acoustic instrument. The best set-up is to plug the headphones-out socket of an electronic keyboard into the mic input, and choose a piano setting on the electronic keyboard. If you don't have any musical instrument that you can plug directly into the mic in, then you can use an acoustic instrument with a microphone, in which case move your microphone closer or further from your instrument to get reliable detection. Too close and you get double detections, too far and you get missed ones. To check for good detection open a piece of music, set Overlay mode and put the cursor in the first measure and play the piece in – the notes should all turn blue if you have perfect detection. It is worth while getting perfect detection – more than one or two miss-detects per piece of music and you may want to use the Insert rather than the Overlay method. The Audio Input button introduces a special entry mode where the pitches you play in will overlay the rhythm, appearing as blue notes. You can delete any wrong pitches using the usual delete keys, without deleting the rhythm. In fact if you have an "interloper" (an extra spurious note) you can delete it and the other pitches will all move along to their correct places. Another method of playing music in acoustically doesn't involve entering the rhythm separately. For this select Input->Audio and then choose Insert instead of Overlays on the Pitch Recognition Panel that pops up. With Insert the sounded notes are entered as in the prevailing rhythm. The same applies if you have MIDI, only you just need to select Insert mode to enter the notes in that case. So by choosing a rhythm (e.g. half-note, quarter-note, or a custom rhythm pattern) and playing in the pitches you can enter the music into a blank score. > > I've looked on the forums and help guides but see nothing explaing how > to > configure Denemo to accomplish this task. > > Thank you kindly for your time and thank you for creating this > wonderful > program. The manual is somewhat out-of-date, but as we are now at version 0.9.14, your version may well be too :) Richard Shann > > Wally Lepore NJ USA > _______________________________________________ > Denemo-devel mailing list > [email protected] > https://lists.gnu.org/mailman/listinfo/denemo-devel _______________________________________________ Denemo-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/denemo-devel
