if I select the 10 midi channel that is percussion sounds,no problem

This is true, because all information on midi channel 10 stays on midi channel 10. It only is sent to devices that communicate on channel 10 and no other channels. This assumes that you have a properly set up midi network.

because the tones percussion musical notes is indefinite,

This statement makes no sense.

but if I choose other channels midi

This is fine. Midi data is specific to each channel. If you have two devices on two different channels, they DO NOT send data to each other when you have a properly set up midi network. If your midi network has something wrong with it, you might have problems. These can be traced back to the user's incorrect setup of the network.

example: timbre of marimba and vibes that has defined and chromatic notes with different heights I'll probably have to schedule problems,

These "schedule problems" will only happen if you have multiple devices on the SAME CHANNEL. Again, midi problems are almost always the result of user errors in setting up the network.

example: I select the note A1, equivalent to 55Hz frequency , in the 32 imputs the next note will be E4 with the frequency of 329.63 Hz,the 33 imput will be the note F4 with the frequency of 329.63 Hz, but it is not what usually happens, the 33 imput back to the first octave bass F1, with a frequency of 87.31, all right?

Not all right. I don't understand what you mean.
