Paul Davis: what is the 'easiest' MIDI interface to get working under the average Linux kernel? what sort of experiences do folks have with getting MIDI working (on a programming level) using API's such as (but not limited to) ALSA, and MidiShare? for me so far, MidiShare seems to

[linux-audio-dev] the stack threat - memory management and RT apps

2005-05-29 Thread Christian Schoenebeck
Hi! I guess everybody of you know that allocating memory on the heap at runtime in RT threads is not a good idea. This can easily prevented by user space / application managed memory pools. But whatabout the stack? Even if you try to use the heap for local variables as well, you (usually)

[linux-audio-dev] ALSA Sequencer API - How to Receive Events?

2005-05-29 Thread Sean Don
Hi all. I'd like to receive Midi note events from another Midi Player. But before I attempt to dive into a wad of documentation, I'd like to know if it's even possible under the following situation... 1) I don't have a hardware sequencer; so, I use timidity as an ALSA sequencer, then pmidi a

[linux-audio-dev] ANN: set_rtlimits for PAM-less systems and perhaps others

2005-05-29 Thread Jonathan Woithe
With the recent adoption of the realtime rlimits patch into the mainline kernel, people have needed a way of utilising this for their music software. There is apparently a PAM module out there which can be used if one's system uses PAM, but for people on Slackware (which doesn't use PAM) - and
