Hello I would like to synchronize OpenGL Graphics with my Synthesizer. the device sends midi-data to a hardware interface, from there they are sent via parallel port, serial or USB to the PC. The aim is, that when i turn a button on my synth, the graphics get animated (instead of pressing a key on the keyboard). Did anybody realize something like that already or has an input where i could find informations on developing such an application? Thanks! Markus

umm, why dont you just get the midi data directly from the midi port on your sound card (ie connect your synth to the midi port on your sound card)? much easier then trying to figure out how the hardware communicates with the pc when using serial, parallel, or usb interfaces. (see the hardware web site for how to develop for it).

doing it the correct way would just require you do read the midi data, done using the win32 api, directx, or the api for the OS you are using. see google for more details on this.

Hi

thanks for your reply and your inputs.
The problem is, that the application must also run on Notebooks....and there is usually no midi-in.

I''ll try to get the informations through google (not succesful until now)

I''m also looking for information of this type. Although I would like to send and receive DMX 512 spec data. I assume that I''ll have to build some sort of 5 pin din to serial/usb whatever cable and then somehow interpret the data that is being sent through the bus. Have any of you guys dealt with this type of thing before??

Any suggestions as to web sites etc would be appreciated.
