Subject: portman?

Hello, my name is Dave. I am sorry, but I do not

speak french. Anyway, your project looks very

interesting. I am working on a bad MS-DOS based

sequencer. I am not looking forward to rewriting in

C++ for Windows (or even porting it to somethign

like Linux). Point being, I needed to get a serial

port to midi interface, and was consindering buying

on. I asked the midiman people some details about

the portman, and they were real jerks, and said

they couldn't help me because I wasn't an "OEM or

buying large quantities". All I want to know is...

>>>>excuse me but i don't want using miscrosoft product, but i can
help you

All you have to do is set the port to 115k, and

then output a byte?

>>>>for transmission i think it's the simply solution

Just like you do 'normally' to

the MPU-401?

>>>> idon't know

Thats what I have gathered from

looking at the portman code you have done.

>>>>>>in the code the most important is the configuration of the
serial device

see my file portman.log in the news info at sourceforge

But I

want to make sure before I spend the money and buy

one.

>>>>>don't buy it !!! because midiman doesn't want continious this
product and driver:

see at NOTEMIDI project . (on google)

it 's a serial midi device too and the linux driver is very good

i don't know dos programmation but on linux , it's difficult for
me.

I think the bytes for sending a note on is either

0x90 or 0x80? And then you send the note, and then

velocity. So I guess its 3 bytes to turn a

note on.

0x90 + NOTE + Velocity in this order for note on
0x80 + NOTE + Velocity in this order for note OFF

thanks in advance for your help. if this works,

seeing your page saved me weeks of time in

building/programming a new serial/parallel port

interface.

>>>>>the important thing in the portman programmation , it's is
simplicity of protocol because he has no protocol :)

if you configure the serial at 115200 no parity 8 bits ...
as my program the data transmit work fine

for the received, you must know the use of DTR RTS ...

Oh yeah, do you think that your method of sending

bytes, will allow playback of music ? ie, high

enough performance?

>>>>>>NO, but it can handle midi file well , and it woak good with
my MC303 :)

for all other info see the pdf, a guy send me this

thanks!
