Hello,
J'ai fait l'aquisition d'un Liquid Mix et je ne suis pour l'instant pas vraiment satisfait. Ma configuration est PRO TOOLS LE M-powered 6.8 avec une Firewire 1814. La FW 1814 est connectée sur le port FW 400 de mon PBook (1.25 Ghz PPC G4, 768M DDR), le liquid mix est lui connecté au second port FW du PB via un câble FW800<-->FW400.
J'ai installé les éléments présents sur le DVD d'instal.
Probs 1 : Cela décroche régulièrement et fait planter PRO TOOLS.
Probs 2 : Liquid mix utilise VST>RTAS Wrapper de FXpansion. La version 2 est fournie mais pour les utilisateurs d'un Pro Tools inférieur à la version 7 : NADA, Nothing, quedal : il est symphatiquement indiqué : "version 1 wrapper is available separately from FXpansion" pas cool. Heureusement j'avais la version 1.
Probs 3 : J'ai également de la latence peut-être dû à l'utilisation du wrapper ???. Dans le manuel dans la section spécifique au utilisateurs de Pro Tools il est indiqué que le Liquid Mix est compatible Pro Tools mais mais les utilisateurs doivent être attentifs aux points suivants :
Pro Tools LE has a limited delay compensation feature set (comments atteindre la fonction "delay compensation dans Pro Tools 6.8???? Lorsque je tente de l'atteindre via Display/Mix Window Shows/Delay Compensation impossible de l'activer)
• Delay compensation is switched off on the FXpansioin wrapper, as it is for all plug-ins that use the wrapper
• Users have to manually delay all MIDI tracks by 2056 samples to compensate for this
• Users must manually delay audio tracks which do NOT have a liquid mix instance, by 2056 samples using
the time adjuster plug-in (see doc below)
• The time adjuster plug-in cannot be bypassed without removing it.
• Liquid Mix should be bypassed within the unit, NOT via apple-clicking the plug-in, otherwise the 2056
sample delay is removed.
Delay Compensation in Pro Tools
In Liquid Mix, all processing is done using onboard DSP, so it has almost no effect on your computer’s own
CPU. However, the Liquid Mix unit requires a vast amount of processing power in order to do the number
crunching involved to get the emulations translated. This then needs to be sent to the Firewire unit and back
again, which does introduce a delay.
In order to compensate for this signal delay, modern software packages include a feature called ‘Delay
compensation’, which looks for any delays introduced into any of the DAW channels, works out which channel
that has the longest delay and adjusts all other channels accordingly. All external processing cards incur
delays of this kind.
In the Digidesign Pro Tools DAW, Automatic Delay compensation (ADC) has been included since version 6.4.
This feature is well documented in the Pro Tools User guide, so here we will deal with the important aspects
of using the Liquid Mix within the Pro Tools environment.
Some important points to make are that Pro Tools TDM and Pro Tools LE differ in the level of Delay
compensation that is included. Pro Tools LE users have a limited delay compensation feature set, where all
audio paths apart from wrapped plug-in slots are delay compensated. MIDI is also not delay compensated
and so a manual offset has to be set-up in the preferences menu. Pro Tools HD has a full ADC feature set
and can deal with most delay issues without manual configuration being required.
Please read pages 505-509 in you Pro Tools User Guide, which details the use of delay compensation.
Where to find the VST>RTAS Wrapper
The VST>RTAS (v2) Wrapper is included on the DVD. This will only work with Liquid Mix, not other plug-ins.
To use the Wrapper with other plug-ins, you will need to upgrade to the full version.
VST-RTAS v2 is for Pro Tools 7 and above. Pro Tools 6 is not supported but a version 1 Wrapper is
available separately from FXpansion.
Once set up, Liquid Mix will appear in the Pro Tools plug-in menu as a Wrapped plug-in.
Setting up Liquid Mix with the VST>RTAS Wrapper
• Make sure that FXpansion VST>RTAS adapter has been correctly installed
• Make sure that delay compensation is enabled in Pro Tools.
• Set Delay compensation to Long/4095 samples per channel in the preferences menu.
• Set view delay compensation in Display/Mix Window Shows/Delay compensation.
(This allows the user to see the total amount of delay compensation being used.)
Probs 4 cela fait planter Pro Tools lorsque l'on veut désactivé le plug in.
Probs 5 il ne garde pas les réglages en mémoire.
Bref quelqu'un peut-il m'aider, qu'ai-je foiré? J'ai déjà checké via les FAQ du site de Focusrite mais à part que tous le monde il est beau et que leur produits sont formidables ce site n'est pas d'une grande utilité...
D'avance merci,
