I think ALSA would be better if it had actual documentation for more than like 10% of it.

@sixohsix @mcc option 2: you tell alsa you do not care about time stamps: alsa leaves the time stamps in messages as they were recorded if they have them. god help you if you have multiple MIDI streams feeding the same port, because they will either have "realtime stamps" which are time points relative to that the output queue that event was written to, or they will be in "ticks" which is the same thing except the duration is variable
@sixohsix @mcc in theory you could build a sequencer that does the same thing as what alsalib does under the hood in the first scenario, but as far as I can tell you can't actually read a common reference point for a given event's time offset, so for all intensive porpoises you only have one time point for everything in both cases: "now".

@sixohsix @mcc this is probably fine in most cases since the events are expired as soon as they're created anyway. a midi packet is HOT HOT HOT and should be processed ASAP anyway. But WHERE is "now"? do you have a clock that if you sample it and then sample it again a second later will give you exactly a second of time between the two samples? no. you do not.

@sixohsix @mcc but ALSA insists that there is a "now", and that "now" is a thing that is real and exists, and has a clock and that clock moves forward in fixed increments, and never throttles, and so on. ALSA, despite also having this concept of batched time in its audio processing model i'm pretty sure, does not seem to believe that midi would ever be processed precisely, or need a be sieved in ~0.02 second chunks.

@aeva Thankfully Pipewire is here to save us with less than 1% documentation.
Wait
@shinmera that's fine. all of the linux audio applications that will ever exist have already been written

@jens @sixohsix @mcc ok let's rephrase the question: "I have a set of packets that have time stamps. Half of them have a known interval, but have an arbitrary uncorrelated origin. The other half have an unknown interval, and an arbitrary uncorrelated origin. In both cases, the origin can randomly *change* while playing. How do I put all of these into one common reference frame?"
The answer of "ALSA uses one of your system's clocks internally!" does not answer this question.

Va da sé, se consideriamo l'umanità tutta, sparsa sulla terra, che se il potere e la ricchezza sono concentrati su poche nazioni, queste vanno considerate come oligarchia, giocoforza votate al proprio interesse soprattutto e in primo luogo

King Creosote – Astronaut Meets Appleman (2016)
Se siete in attesa del seguito di “From Scotland With Love” rinunciate senza indugio alcuno all’ascolto di “Astronauts Meets Appleman”: King Creosote non ha alcuna palese intenzione di sfornare seriali concept-album, né tantomeno aspira a diventare il nuovo idolo indie-folk. Pur avendo in parte addomesticato q... https://noblogo.org/available/king-creosote-astronaut-meets-appleman-2016

@grabbi_it "ah, la vanità! Il mio peccato preferito..." diceva un luciferino Al Pacino.
Il fatto è che certa gente dovrebbe evitare di esporsi e imparare a volare a bassissima quota, anzi dovrebbe proprio prendere il brevetto di volo stealth.
Scommetto che se Bornigia si fosse fatto i cazzi suoi, nessuno sarebbe andato a scassargli i cabbasisi
