A question. How to send SYSEX messages #2

Open tentaclius opened 2 years ago

Hi! Thanks for your work! Found the library quite useful when playing with cl-collider.

This is not an issue, rather a question. I can't quite figure out, how do I send/receive SYSEX messages using the API provided. Is it even possible? I see the type is defined in driver/event-lookup.lisp, but it looks like it is ruled out in %send-event.

Hi! Glad you find the library useful, but the vast majority of the work was not done by me; all I did was re-upload it (the original author deleted his GitHub account) and add a few small patches. So to be honest I am not sure if sending SysEx is possible currently, nor how easy it would be to implement if it's not currently possible. Not to mention I'm not super familiar offhand with how SysEx works on a low level.

Thanks for pointing out that the library already has some mention of SysEx though, that's useful information. I'll take a look when I have time and see if I'm able to get anything working.

Thanks! I'll keep looking and will update this issue if I'll manage to find the way. It looks like the lower level calls should allow it, I just need to train my eye to read CFFI macros.
