All in all I will do make this router on one's own , but me very not like when developer whitch have all , and this developer so resisting offer which do his product better

And I do not like when someone is so selfish and narrow minded that he simply cannot understand that what he thinks to be better can be worse for someone else. I'm really curious what you would do in the opposite situation.
Let's play with the unlikely idea that you created a 16 -port router for your own needs and then I would write to you:

"Hey Roland User,
Remove the unnecessary 16 ports since my Midi Player only needs 64-channel/ 4-ports and this would make the interface easier to handle and even work on my legacy PC with 1024x768 resolution.
There are no known classic Midi files with more than 64-channels which makes your cluttered user interface hard to understand. Also please remove the unnecessary reset options since my Midi Player already contains all of them so they are completely redundant. Please, make these changes urgently so your plugin can be better."

You have to realize that no one wants to spend hours of work on his own hobby project in order to implement the ideas of someone else when he genuinely does not like those ideas.
If you fail to understand this then we finished here.

Zoltan , this example not correct , if only I write to you exactly as you showed , so this was be stupid , then I very good understand you reject , but my offer this not cut functional , a extend functional , now I try make MIDI Router , source code https://www.mediafire.com/file/no6hds0sumxqrm3/1.pas/file , but in this on Pascal ABC , I recive next not impenetrable problem , so as this work , always use Direct Music interface , and this can not set two Drum channel , and can not transmit sysex for inserting effects , I not known what do for use WinMM system
I'm trying contact you for get extend version WinMM Multi Port VSTi , I'm trying ask AI for fix my app , but all it doesn't work , you has source your WinMM Multi Port VSTi , I trying make its analogue , but this can not do it
I have never before not ask delete functional , but I always ask extend functional
If keep your example , so this as if you have only Roland MT-32 and because this module have channels 2-10 , do ask remove channles 1 and 11-16 , this stupid
