I found this recently. Kinda sucks, huh?

Especially as I was firmly in the "pfft, PDC? who needs that!" camp.

use a rack, and it will work.. (I have SIR running in a delay-compensated send-return loop as I type)

Its a common technique and a good idea to use two reverbs.

For creative effects (e.g. colouring or fattenning a sound like a drum kit) use a reverb (e.g. Ambience, Kjaerhus Classic, or the native one in your host) as an insert effect on the track.

For overall reverb to place your "performers" in a "space" use SIR or another convolution on the master out during the mixdown stage. In this instance PDC is not an issue.

This is interesting stuff. I've never had any luck with SIR working in real time. ConvoBoy is the ticket. Has a lot of nice features too and you can't beat the price.

Reqs, do you have the free or inexpensive version of Convoboy? I probably should get myself a convolution reverb, but if Convoboy does it, why pay for Voxengo. I am no reverb guru, that's for sure.

So much help I am now confused

OK I loaded up a project which has a midi drum track, a midi bass track, and a midi keys track, each going through its own instance of sfz and (in order) ns_kit, fretless soundfont, and a B3 soundfont. I stuck SIR on the drum track - no timing issues.

I pulled the snare to a new track and just SIR'd that - no timing issues. Does it just vecome an issue when things are busier?

As far as I am aware I haven't 'enabled' any delay compensation (wouldn;t know how

)

It would become an issue if your kick and snare were coming from different outputs of the same plug-in (wrapped in another rack).

The solution is to drop a copy of the rack filter onto all the different outputs, setting the ones that want no effect to send 0dB: so long as all the outputs have the same PDC requirements, it should work.

Sounds like you're using SIR as an insert here. PDC is automatic (under the bonnet) - nothing to enable.

its enabled by default: select a track with SIR inserted, and look at the "advance" field in the properties panel. The value here is the amount of latencty reported by the plug-in: if you switch off "auto-advance" you switch off PDC.

Can you elaborate a bit? I thought the new Aux/Sends were actually racks but implemented a different way. I'm certain I read on this forum that Racks _didn't_ have PDC. Hmn, I will investigate.

Racks do have PDC so long as the entire rack (and all its outputs) require the same amount of delay compensation.

For this to work the plug needs to be inside the rack however. It is possible to use a rack with its inputs connected directly to its outputs as a simple generic "aux send", where the effects are inserted on the return track after the return rack. This works fine so long as no PDC is needed.. and this seems to be what the aux sends are doing.

Its actually very quick and easy to set up a rack as a send:

1. insert plug on the return track.

2. right-click -> "wrap this filter in a new rack".

3. copy the resulting rack filter to one of your send tracks.

4. set dry level up full, wet level off, and set send level with the "input level" sliders.

5. copy this filter to remaining send tracks, and set send level for each.

platinumears: Thanks! (got the setup in the other thread, cheers)

I have used ConvoBoy in Tracktion for some time and I find it doing all well...but recently I tried out RevolVerb, http://revolverb.hostrocket.com/, a realtime convolution engine. So now I can even use amp-simulations and reverbimpulses live, with even lower cpu-load than SIR and ConvoBoy!

Some minor bugs, like sometimes you need to double click to open the impulsebrowser and changing some impulses during playback will cause noise...

Maybe it´s something for you who are experiencing latency with SIR...If you read the important notes at the bottom of the webpage it should do just fine in Tracktion... (Can´t seem to download the zipfile right now though, maybe something temporary...)

New here btw...love Tracktion...don´t we all?...

SIR reverb - need I look further ?
