Digital output configuration / Configuration Sortie numérique   Voice_overflow.png

When playing the "Myriad theme" (? > About), Harmony Assistant "heard" audible clicks that had escaped my notice.  
 
The number of voices had to be increased to 27 in order to play this "small" ensemble without upsetting Harmony Assistant's acute sensibilities.
 
Evidently, the number of voices has to far greater than the number of staves.  (I am astonished to see that the maximum number is 512.)
I am guessing that "overlapping" notes  (Pressure time > 100%) is one cause; unused instruments (metronome) perhaps another?
 
The number and size of buffers is another mystery to be solved - one that can cause an orchestral score to vanish from the screen
(Windows closes H.A. without warning if too much memory is used) using the 64-bit version, but not with the 32-bit version.
 
 
Lorsque j’ai joué «le thème Myriad» (? > A propos du logiciel), Harmony Assistant «entendu» audible clics que je n’avais pas remarqué.  
Le nombre de voix a dû passer de 22 à 27 pour jouer ce «petit» ensemble sans bouleverser les sensibilités aiguës d’Harmony Assistant.

One output voice is sufficient for castanets, an "instrument" with a very short decay time.  
 
With resonant percussive instruments (timpani, for example) H.A. reports "hearing" clicks with 8 voices (below).
I hear "crackling" rather than clicks.
 
Depending on the tempo, this instrument alone may require 12 "voices".
 
(Sometimes H.A "hears" clicks that I do not; sometimes I hear a crackle that H.A does not report.)

As they might say "oop North", that's a cracking joke!    
 
My playback was more like fire,as in "Chariots of Fire" than Perrier Music

Tony,
What  do you mean by "HA heard audible clicks" ? I would understand "plays" ?
Now, I fail to hear more than 3 or 4 instruments, nothing resembling a computer click.  
 
And, by the way, can one change which score is played?  
Furthermore, I don't recognize Händel's Watermusic in it... or is it simply a joke?

I refer to the error message that H.A. gives (sometimes) - look closely at  the images above.  
 
Try playing some notes with the Taiko (percussifs) with only 1 "voice" (track?) set in Output Configuration.  
 
As I said, sometimes H.A. "hears" problems that I do not.

If a "voice" is used from the beginning to end the of the sound of each note,
if you have slight reverb or decay on a timpani while you play the second, this means 2 notes playing at the same time (one is at its decay, the second is starting).
 
Increasing the number of voice increase probably memory or processor consumption, and I think, with nowaday computers, it's not a probelm as it was 20 years ago.
 
 
Andre_B : about Water music / Chariots of Fire / crackling / sparkling...
this is a joke because Tony mistranslated a word in French with a funny meaning that doesn't make sense for music, but for water... or sometime for personnality/temper of a girl

The error message HA displays says something about hearing clicks.  I don't remember the precise wording.
 
Myself, I never pay attention to this message, because whatever is going on, I never seem to hear any problem.  Either my ears are going bad (possible, I'm 65, after all), or I just don't care enough to pay that much attention (also quite possible, I must admit).  Either way, I'm glad we have Tony to help us figure these things out.
