Default First of all +1 from me

I've been using the feedback option to tidy up my track list with the auto-mute master option as safety precaution without any problems so far.

Did not notice that. Apparently I never used any plugins causing a delay on these instrument out. A bit disappointing to learn that now, although it technically makes sense (for real audio feedback).

So I'm all for separating midi and audio feedback. As ED pointed out sending midi from Ch1 to Ch2 and audio back from Ch2 to Ch1 isn't even a feedback and should not be treated as such by the PDC.

I think that's only true if you have plugins on the child channel causing a delay.

When I started using Reaper for the first time, this very feedback issue as one of my biggest '???' -moments (feedback protection was enabled and I didn't know why audio didn't flow). I very much assumed that naturally MIDI and audio feedback were handled separately so I had a really long hairpulling session because I didn't know what was wrong, until I turned off feedback protection.

If this is isn't changed it might at least be useful to notify users somewhere in preferences that MIDI feedback is handled along with audio.

No. It happens always when two tracks are in feedback routing.
The delay depends on current buffer size, but there is always one.

Imagine if there was no delay, the signal should get routed instantly
back and forth between two tracks ad infinitum. Sounds like an
endless while(1) loop which usually ends with a crashed app or system.

But if a track sends midi and receives audio then this surely isn't even feedback anyway???

Is this some abstract kind of feedback being discussed?

This is the whole point of the request. Reaper treats this
connection as feedback routing, as there is a link between
tracks in both ways. Even though no actual feedback is
happening as the data types are different, and user makes
sure no looping of data occurs.

It could technically be called a 'bug' but since this kind
of routing was not the original design, it was filed as
a feature request.

Right, it's just that this type of thing...

...seems to suggest that you think it is 'feedback routing.

I guess I took it too literally and you're all just using this type of term for reference only...

ED's request is essential IMHO.
Current Reaper's way of handling multitimbral VSTis is cumbersome, tiresome and illogical because of this simple limitation.

Every time I start working with some multitimbral VSTi I'm asking myself: "Why, oh why I have to fiddle with so many tracks and keep all this routing hell in my head? Why can't it be simple enough to have VSTi as a folder track and timbres/channels/outputs as single tracks inside that folder?"

... as it is not a "real" audio feedback loop, then (I think that) the latency would not diverge as the plugin is only in the loop once.

----------------------------
But I may have lost the plot.

Yes, you're absolutely right. I guess I hadn't noticed because I was using a really small buffer size. But even then you can clearly the comb filtering when using the exact same sound on two tracks where one is in a (fake) feedback loop. Bummer.

Thanks for the support, people.


I just don't know why can't the two separate data streams be TREATED separately... It should be possible, without screwing up PDC.


I'd really like to hear an explanation from schwa or Justin. Because this is something that for sure can improve the workflow of us MIDI guys - so we can have a MIDI item on the same track that serves as audio output (instead of doubling the number of tracks, then hiding audio outputs in TCP and hiding MIDI tracks in MCP...)

Exactly right. But Reaper thinks there is actual feedback loop,
so it introduces latency unjustified. You understand the problem,
but specifically it's not the loss of PDC that is the issue, rather the
detection of when the feedback actually happens.

This thread is looping itself.

Edit: Also ED, could you include FR link in your OP for more votes?

The flexible routing is one of the main things that brought to Reaper in the first place - and I'm sure I'm not the only one. So this really needs being fixed.

Maybe there needs to be some kind of feedback detection logic --> only introduce the delay if there actually is a real feedback loop.

let's hope it was at least detected, we shouldn't
delay this any longer.

A pretty image I'd prefer, same catch phrase but with a spelling mistake.

Anyway, +1 000 000 000 for that feature. I see no reason why.

I have to say, these last few posts seem rather desperate .

But it's nice to know I'm not the only one desperately hoping for this to be fixed.
