Altiverb 7

No Altiverb 7 in Logic after installing/updating Problem: Installed or updated Altiverb 7 and now it does not show up in Logic.

Solution: Restart your mac.



Somehow (we are still trying to find out why) the macOS ignores Altiverb 7 until the computer has been restarted. This is why Logic (or Ableton Live, or any other DAW that uses Audio Unit plug-ins) does not show the Altiverb

Restart your computer.

The problem should be gone now.

Surround in Reaper (Altiverb 7 XL) open the add fx window in Reaper on the 6 channel track

then right click on the Altiverb plug-in and make sure this option is checked:

☑️ inform plug-in when track channel count changes





When you then insert Altiverb 7 it should become 6 in 6 out and you will be able to choose the surround IRs in the IR Browser. There is a little trick you need to pull off to get this to work:When you then insert Altiverb 7 it should become 6 in 6 out and you will be able to choose the surround IRs in the IR Browser.

What is the difference between Regular and XL ?

There are three differences:



Altiverb 7 Regular supports up to stereo input and output

sampling rates up to 96kHz

plug-in formats on windows: aax native and vst, on mac: aax native, vst, audio unit, mas and rtas Altiverb 7 XL supports: up to 5.1 surround in and output

sampling rates up to 384 kHz

all plug-ins formats Altiverb 7 Regular supports + TDM on Mac OS X

So, in short, if you do not have sessions on 192k and you work in stereo only, Altiverb 7 Regular will do just fine.

If, at a later stage, you would like to upgrade from Regular to XL this is possible. The upgrade cost is just the price difference so you won't loose any money going for Regular first. Altiverb 7 Regular and XL sound exactly the same and come with the same IRs.There are three differences:So, in short, if you do not have sessions on 192k and you work in stereo only, Altiverb 7 Regular will do just fine.If, at a later stage, you would like to upgrade from Regular to XL this is possible.

Altiverb recalls only Teldex IR in Digital Performer (DP) There is a situation where the Altiverb plug-in can revert to default settings when loading a project in Digital Performer.



This is caused by the fact the Digital Performer (DP) supports three plug-in formats: MAS, AU (audio unit) and VST.



How?

Example: When you save a project with the Altiverb MAS plug-in. And you then change the default plug-in type in DP to AU and re-open this project. DP will load Altiverb, but DP fails to transfer the saved Altiverb MAS plug-in settings to the now Altiverb AU plug-in, and Altiverb then reverts to loading the default settings (which is the Teldex IR).



When this suddenly occurs you are most likely using a different plug-in format then you used before. Try to find out what you used before, force DP to load this Altiverb plug-in from the plug-in settings in the DP preferences and then restart DP and re-open your project. The right settings should load again then.



If you need any help with this let us know. Send us for instance a project file that will not open correctly, then we can quickly help you out.

Mono to stereo and stereo to stereo What is the difference between the mono to stereo and the stereo to stereo options in a stereo out Altiverb ?



Best way to understand this is to go back with me to our sampling session when we recorded to room's acoustics for the IR in Altiverb.



mono to stereo

We put a single speaker in the center of the stage and two mics in the audience.



This results in a mono to stereo IR.

When you playback your audio through this IR in Altiverb, it will sound like your audio comes out of that single speaker from the center of the stage (mono!) picked up with two microphones (stereo!).

This IR gives a stereo reverb, however the input is (mixed to) mono, as there is only a single source on stage.



When you want to process a vocal (mono) or direct recorded electrical guitar or something where the panning is not important the mono to stereo IR will do just fine (pro: costs half of the processing then a stereo-to-stereo IR, so it is more efficient in cpu and memory).



stereo to stereo

back to recording the room

this time we put two speakers on stage, one on the left and one on the right side of the stage and we record again with the two mics in the audience.



When you playback your stereo audio through this IR in Altiverb your stereo signal comes out of these two speakers.

Easy to picture here that your original panning will be maintained using a stereo to stereo IR.



So basically it comes down to this:

is your input stereo or is it panned in stereo ?

use a stereo - stereo IR, else you will loose the stereo information in the reverb (although the reverb is stereo).



Sometimes even when using stereo panned sources a mono to stereo IR can be preferred as you do not want the panning to be reflected in the reverb levels. But this is a mixing decision which depends on taste mostly (and music style) and I dare not to advice on that :-)
