Message #187908
Hi, Many thanks to all for the answers (Peter, Blair, Rich, Howard), and since several overlapped I'll try to cover them all (so far) with this: 1. I believe I have found a good workaround to the problem, which is the following: a) enter a new note onto the score where Logic didn't show one. b) change the note's velocity to '1'. c) put a slur on the score from the previous note. What this does is exactly what I need: the new note isn't audible, and the existing recording sounds just like it did before. But a musician reading the score now has the correct note information. 2. I don't agree that it would be difficult for Logic to do this automatically. Since the pitch bend has exact data, every time a chromatic note is passed by the bend, Logic would add a score note and tie/slur at that point. It could be an option in a dialog box for the score: "Notate pitch bend notes chromatically". (And yes, pitch bend is a relative scale, but as the manufacturers of my hardware warn, the bend range has to be set the same on the hardware and the synth, or else you get incorrect results anyway. So Logic already knows exactly how this scale refers to musical notation, when they're both set the same; it just needs a trip switch so that when the pitch passes the threshold of the next chromatic note, it enters it into the score.) 3. I tried using the 'audio to score' function, out of curiosity, but it's worse. It doesn't understand bending pitches at all, as far as I can see. Thanks, steven rowat

Good idea! And with "No Overlap" ticked you wouldn't have to change the length of the original note. And if the notes with 'velocity = 1' still turn out to be a problem, you could use a transformer in the environment to filter 'em out. > What this does is exactly what I need: the new note isn't audible, That can depend on the velocity sensitivity of the receiving instrument, hence my suggestion. > 2. I don't agree that it would be difficult for Logic to do this automatically. Perhaps not, but what does seem to be difficult is getting Apple to put much effort into improving Logic's score features. They're quite possibly flat out trying to keep up with other apps in audio features, but, as has been stated many times, a few improvements in Logic's score window would turn it into a killer program for scoring. Cheers, Bill

Now you get a continuous stream of tones. If you want to describe that you have to take an appropriate measurement system. If you take Hz, you'll get 441, 442, 443 and so on. If you take any musical scale system (and chromatic notes are a scale system), you cannot measure on a regular basis but you have to check wether the frequency reaches a valid note of your system. 1 - There are no "valid notes" in the universe. 2 - You would need a tolerance window of a certain width. Wide enough for a technical system to detect a new note and so narrow that the human ear does not detect a tonal change (we have pretty good ears for that!) 3 - If you use standard tuning based on 440 Hz you would need a notation system to write a note with 441 Hz. And what about 441.3967 Hz? You could just notate the frequency, because the decimal system is working (so la la) and I assume you do not play frequencys with a periodic value. That would bring us to a philosophical discussion :-) We do not play notes. We play tones and just constructed a system which allows us to describe more or less exactly what we hear. Pitch bend is outside of this system. You are dealing with music, with physiological phenomena. Our chromatic scale is very coarse compared to what we are able to hear. It is too coarse for you, therefore you use pitch bend or a slide bar. And therefore you invented your "Analude", a very interesting instrument btw. But you can hardly break out from a system and then go back and notate your music in a scripture of the same system. > (And yes, pitch bend is a relative scale, Pitch bend is no scale at all. It just says "higher" or "lower", without saying how much. An analogue comparison: if you bend a guitar string 1 cm, you do not get the same tonal difference on all strings - the individual result depends on the construction and the current state of the string (material, thickness, tension, already bended, etc). We have continuous bending possibilities like our fingers, slide bars, bending the guitars neck, playing trombone or singing saw, our voice, rolling a piano across the room to enjoy the Doppler effect... And we can bend in steps and with different resolution: drop-D lever of a guitar (2 steps), MIDI coarse pitch bend (127 steps), MIDI fine pitch bend (16,384 steps) or the resolution of digital instruments, which might be made more coarse than necessary i.e. by the "Tune" fader of the instruments GUI. > but as the manufacturers of my hardware warn, the bend range has to be > set the same on the hardware and the synth, or else you get incorrect > results anyway. Many devices do not have an adjustable pitch bend range. You you depend on your audio instrument to stay within the range you want. > So Logic already knows exactly how this scale refers to musical > notation, when they're both set the same; it just needs a trip switch > so that when the pitch passes the threshold of the next chromatic > note, it enters it into the score.) I think I get your idea. Yes, the Logic MIDI system and plugins could exchange information about pitch and the currently used scale. But that won't help with notation: the most you'll get out are 11 notes for 1 octave. That is just a glissando and you can also press your slide bar against the guitar's frets to get the same sound. > 3. I tried using the 'audio to score' function, out of curiosity, but > it's worse.

Logic tries to detect new notes, I guess it sees an attack in a certain frequency and says "this is a note". No attack -> no notes. Peter Ostry

Processing the playback would generally allow sort of "MIDI ducking", at least with quantized notes :) Peter Ostry
