  Hello, Is it possible to create a monophonic soundfont? with 1 note polyphony, like moog?
  
  Sorry for the language.

  if by "monophonic soundfont" you mean a soundfont made up of mono instruments, then yes, and it's much much easier to create and adjust mono instruments than stereo instruments. But if you meant polyphonic as "playing simultaneous notes in one note", setting up instruments like that are possible but much harder to create, either way I didn't quite understood your question.
  
  A propósito, bom saber que temos mais BRs entre nós auahauha

  Hi Filipe, thanks for the reply.
  I want to produce a lead, so that when I apply a note it will be unique, if I press another note and keep a previous pressure, or alternate between two.
  
  algo como esse fusion lead

  "Olá Filipe, obrigado pela resposta.
  A ideia é produzir um lead, de modo que quando eu aperta uma nota ela seja unica, se aperto outra nota e mantenho a anterior pressionada, o som alterne entre as duas."

  Ah yes my friend, then we're talking about portamento!
  
  Portamento is a MIDI Control Message that makes the synthesizer slide between notes monophonically, instead of playing them simultaneously. It consists of three CC messages: CC 05 (Portamento Time), CC 65 (Portamento On/Off Switch) and CC 84 (Portamento CC Control).
  
  The CC 05 tells the synthesizer the amount of portamento to perform, i.e. the time taken to switch from one note to another, so a low value means faster transition, while a higher value means slower transition.
  
  The CC 65 is the switch of the function, i.e. activates/deactivates the portamento. Note that the portamento function affects the whole channel, so whenever you want some specific channel to use this function, you set the CC 65 to any value from 64~127, and you set to any value between 0~63 to deactivate it and turn back to polyphonic mode.
  
  The CC 84 is what make this function really work, because portamento isn't something you just activate and it magically do everything for you. With CC 84, you tell the synthesizer "in the next transition, bend from the key XXX to the next one", where XXX is the number of the previously pressed key. For example, imagine you're playing the sequence F5-G5-G#5-A5. This is equivalent to 65-67-68-69 in key codes. There must be CC 84 events right after every pressed key with the value of these keys, so when you press G5, the portamento will bend from F5 to G5, at the speed defined at CC 05.
  
  That said, you was talking about a soundfont in which you implement this functionality. I think you can kinda do it with modulators, but the MIDI standard strongly discourages us to do it because of the nature of some functions. Some synthesizers even ignores modulators with portamento setups. The only way of doing this is by setting up portamento at your MIDI files, or if you want to do it live, adjust your synthesizer with the said CC messages.
  
  Bottom line: this isn't something you do with soundfonts!
  
  Hope that helps Um forte abraço!
  
  EDIT: I was testing here on my editor these portamento settings, and I found out it works with every melodic instrument, even with pianos or chromatic percussion! So if you want to make your own leads to play them in portamento mode, you'll just have to worry with their sounding in sustain, so make sure they'll be loud and nice!

  Obrigado Filipe pelos pela resposta tão técnica e completa.
  É uma pena não ser possível em soundfonts.
