Hi William,

You are sinking !

Note of the author :

I have simplify the whole thing not to make it too complicated so Willian could understand the difference of a programming language and a protocol.

VSL SE is wrote in a programming language, the most use at this time C or C ++ but thers is also Java, Algol, Cobol, Basic, RPG II.......

SE will receive Midi messages from your DAW (Logic Cubase...)

A programming language will look like this (this is inside SE) ;

Begin:

read message from midi else on error wait 1 ms then go to Begin

MidiChannel = message [1,1]                          ;* I extract the midi channel, the type of message, the value of the note, and the velocity

type = message [2,1]   

note = message [3,1]

velocity = message [4,1]

If type = CTRL the gosub ctrl                                               ;* if it is not a note I will go to the subroutine that is taking care of controlers

IF note >= c1  and  <= B1 then do                                    ;* i check if it is not an articulation change

       If note = c1 then

       read staccato sample from file

   else 

       if not is c#1 then read legato sample from file

   end

else

.........

If I simplify the Midi protocol it looks like this ;

midi01noteA066,midi01noteB044,midi01endnoteA0,midi01endnoteB0,

Explication :

on midi channel 1 I send the a0 with velocity = 66, I send B0 with velocity = 44, I send end note of A0, I send end note 0f 0

So dont speak of things you dont know about !

If my memory is good Midi is a very bad protocol language because the sender just send and the receiver just receive, it is not possible to say in midi "please resend message xxx I have not understand "

With protocol like BSC it is much more complicate, it looks like this : 

beggining of a xx bit message,......(my xx bits)....., end of message, control checksum

so when the receiver read the message it extract the 64 bit , to the calculation of the checksum, compare with the checksum send by the sender.

If the difference of the checksums is different than zero it sends a message back to the sender so it sends the block again !!!

P.S. I have been programming for 30 years, made a lot of teletransmitions between small and VERY big computer, I have also created a language for talking between host and printers over Postscript

sorry, midi is not a programming language, and that distinction is not splitting hairs. At least not to a programmer :)

O.K., I stand corrected. 

I had better not post anything more here.  I'll leave it to Cyril and the experts.  What do I know?  I'm only a musician.  I know some scales.

'Only' a musician? I'd put the skills it takes to make good music right up there with brain surgeon and nuclear physicist. But I sure as heck don't want to  -think- like a scientist. Being creative takes up all the brain space I got.

So if you could listen to my demo (in the post on slurs) I'd hold ya in even -higher- esteem than I already do. [:D] (Until this forum allows me to send ya an e-drink, flattery's all I got for incentives.)

One other thing Cyril, that last post of yours is not impressive, it is simply stultifying.  I assume your purpose is to bore people so intensely that they simply give up arguing?  If so, you can congratulate yourself on a job well done. 

William,

I have spend a lot of time to write the previous mail to explain to you the difference between a programming language and a protocol so you don't die idiot, and instead of thanking me you are insulting me !!!

Many thanks !

Cyril

 Cyril,  maybe it is a language thing,  but you do come across rather egotistical, I think that is why you get a hard time sometimes.

 I have a notice up on the wall in  my studio, which many read and reconsider what they are about to say:-

Those people who think they know everything
Are annoying to those of us that do.

[:D]

I keep my mouth shut on subject I dont know.

I help only on subject I know.

A lot of people are saying "thanks" for my help

I have quite a few people speaking directly to me by mail or by phone, lately I have send a Logic template to help to understand Event edit and IAC !

I was trying help William to understand !  Too bad ! I have spend my time for nothing !

Cyril I thought you were trying to be a smart aleck. I got rid of that post by the way but you put it back on.  Anyway I realize you are correct about the nomenclature.

you deleted too late, so it was sent to everybody that have subscribe to this tread

 Well you could easily edit that out but you don't want to, which is fine with me.  It is all trivia.
