Are there any projects regarding this topic? I recently started coding
kernel modules, however, there are some design issues involving "way" of
MIDI implementation, so i hoped to contact somebody who's working on the
same thing, or to join develop. team if there is any project underway.
Anyways, the first dillema i have is about softsynth rendering, naturally
early-stage drivers wouldn't use sc's onboard wavetables and their
hardware means of MIDI rendering, so i would rather use software MIDI
playback. Usage of hardware functionality should come later. The thing
that bugs me, is it worth coding this inside of kernel module? Meaning
that some /dev device inputs midi messages to kern.module, witch uses
built-in software synthessis based on SF2 specification for MIDI
rendering. There are already userland programs that do that, like timidiy
and fluidsynth. Maybe it would be better to start on hardware functionalty
at once, eg. pure device drivers that control soundcard's MIDI port,
however, allaround kernel module should bring a decent degree of
standardization. This is the way software MIDI is implemented on Windows
and MacOSX, kernel mode rendering through software synthersizer (altrough
i think they use DLS synthessis rather than SF2, but that really isnt
important). So the question is, what is the best goal for MIDI on FreeBSD,
a quickest way of controlling external synths/MIDI hardware (meaning ditch
the software synth and set your mind on various hardware specs), or an
all-around MIDI drivers providing playback without "3rd party" userland
apps?
Thank you in advance.
