OK, that sounds good to me. I look forward to seeing your vids!

As soon as I posted the link I realised I hadn't given instructions on connecting qtractors output to the Hardware Playback ports hence thats also missing in the screenshot. Might be a good idea to add that in and replace the screen shot too eh? :/

The one question that arose whilst I was writing this latest chapter was - why is it that Claudia sometimes automatically creates a new studio when you open it, sometimes not? I can't find the option to toggle this.

Good news with Carla and the LV2s!

Dan, I'm a wiki wimp, and not comfortable with wiki editing. Can I suggest a couple of edits.

Catia cannot save LADISH studios


suggest just Catia cannot save connections

reasoning: They are not actually "LADISH" connections or studios, they are just, in Catia, connections.

next: Can I suggest a Jack Configuration subheading? Jack can be configured and controlled in either Catia or Claudia, and the most important thing about this is that jack configuration in Claudia is saved with a studio. Thus, different settings, and even different interfaces, can be saved with the studios that need them. The usual example given is a low-latency setup for dubbing, and a higher-latency setup for other work. Different sample rates might be appropriate to different projects too: for example, I do my listening at 44.1, because most of my music is, but I record at higher res (I can't hear the difference, but hey, perhaps someone can).

Thanks for the constructive feedback Thad - they're both good points. I was thinking about mentioning the settings so now I've adjusted the last paragraph to include that and I've also changed Catia's description.

I'll prob not do anything else (including adding in the missing connections and updating the screenshot) to that page now until F and wolftune have edited it as they see fit.

Sure! You responded very quickly to my suggestions :) : I was thinking that, eg, Falk might be telling you if I was actually wrong about anything before implementing them

Aiming a newbs, you might mention here that latency and stability/lack-of-xruns is a trade off or a compromise, and it is not always necessary to work for absolute minimum latency.

By the way, I don't need this, but might play with it one day just for the record (and maybe this is a typical newb question :o)... when you use jack_iodelay, do you connect both channels: left-out to left-in, right-out to right in?

F:

Yes, that and having flash player open in a browser are two of the most common xrun generators I'd say. I'm not sure this info belongs in a chapter about latency though - maybe we should change the name of the chapter to 'JACK Perfermance tips' or something more generic and bundle all such hints in?

Thad:

The point you make about 'latency and stability/lack-of-xruns is a trade off or a compromise' is already covered earlier and It has been stressed multiple times that optimising JACK for low latencies is only required for those doing overdubbing.

jack_iodelay only has 1 input and 1 output channel.

We can just change the latest chapters title to 'Minimizing latency and xruns' then we can squeeze more tips into that chapter without being OT

I've edited the new chapter so its now called 'Minimizing latency and xruns' and its where we shall put any xrun killing tips such as the ones we mentioned here earlier - I just thought of another actually...

Just a note of clarification (should be added somewhere to the docs maybe):

Latency is involved in both the latency for live feedback of your input and in the compensation when overdubbing, but these are totally separate practically. One relates to your experience while playing live. The other relates to things being adjusted after the fact in order to compensate and match timings.

At least one of the comments just now by someone mixed these up. Doing the latency compensation settings has NOTHING at all to do with xruns.

Hi wolftune!

The most recent chapter is called 'Minimizing Latency and xruns' but I don't mean at the same time - hence the hopefully clear division of the chapter between the loopback latency and the xrun reducing tips. I've only bundled them into one because the extra latency test didn't seem like enough for a chapter on its own.

If I have skewed either meaning throughout the manual, feel free to fix my errors. Thats why its a wiki!

EDIT: Based on your reply, I thought this was clear. Now that I look at the wiki, I see my concern is totally valid!

There is no such thing as "minimizing loopback latency". It just exists. What we do is compensate for it by moving audio after it has been recorded.
