Sometimes you can also improve the results by switching to a different algorithm: for instance, if you are stretching kick-drum sounds to get a longer, richer thud, it is worth trying Polyphonic mode rather than the usual Rhythmic, and increasing the Decay value. Here, Warp Markers are being used to move a syllable change within a word so that it coincides with a musical event. Prior to Elastic Audio, producing believable varispeed effects has been difficult.
It could be done by adjusting the clock speed of Pro Tools and somehow recording the result; then came along a couple of Audiosuite plugins, including Wave Mechanics Speed, Waves Soundshifter and Serato's Pitch n' Time, which could render good varispeed effects, but none was especially cheap. Now, however, Pro Tools can do it out of the box: simply make sure your tracks are set to use the Varispeed algorithm and draw your slowdowns and speedups on the Tempo track.
You can use Elastic Audio on samplebased tracks, but if you want to automatically conform a Region to the Session tempo, you'll need to switch your track to the tickbased timebase.
You can then rightclick the Region and select Conform to Tempo, and Pro Tools instantly moves all the events so they line up with the tempo of the track. It seems so much more 'intelligent' than Beat Detective, which may well be down to the improved transient detection. You can also quantise audio to a groove, rather than the strict tempo of the Session.
This is accessed from the Event Operations option in the Events menu; if you choose the Quantise option in the submenu, you can select a groove from the dropdown menu.
Make sure you have Elastic Audio Events selected at the top — if you have Audio Regions selected, Pro Tools will move the complete Region rather than the elements within it. At last it's possible to create realistic tapestyle varispeed in Pro Tools, by switching tracks to Varispeed mode and editing the tempo map.
Does Elastic Audio replace Beat Detective, then? In many ways I think it probably does, although Digidesign have added an improved analysis option to Beat Detective, which suggests they think there is life in it yet. The key difference is that Beat Detective 'cuts up' files and moves small regions around to conform events, whereas Elastic Audio uses time compression and expansion.
I had expected that Beat Detective would be the only way to be sure you could guarantee absolute phase coherence when moving around groups of events across multiple tracks. However, I understand that one of the reasons why version 7. Certainly, judging from the content I have played with personally and heard in demonstration, Elastic Audio is more than good enough at reconforming multitrack events without creating undesirable sideeffects.
It took me ages to sort out and with Elastic Audio it would have been done in no time at all! Various other aspects of Pro Tools have been improved to make integration of Elastic Audio as smooth as possible. Many of these enhancements are found in the Digibase Browser. At last, there is a volume control so you can turn down the volume when auditioning samples in the browsers. I, along with many others, am fed up of being blasted when auditioning loud samples and files, so this is very welcome.
A new Conform to Tempo option means that files being auditioned in the Browser will be analysed and then will play at Session tempo rather than their native tempo. You can also audition loops while the Session is playing, in which case Pro Tools will wait for the downbeat and play the samples in sync with the Session.
The volume control enables you to 'mix' in the sample and hear it in context with the rest of the session. You can now rightclick files and folders in the Digibase Browser and analyse them in advance, to save you time when looking for files for sessions.
Analysed files have a big tick against them and display a duration in bars and beats. They can be dragged straight into your Session Edit Window, whereupon Pro Tools will create new tracks with Elastic Audio already turned on and the files conformed to the Session tempo.
When you select one of a pair of Split Stereo files or a group of multichannel files, the entire file now previews together unless you press the Shift key when you start previewing. Another area of the program that has changed in v7.
The DAE Playback Buffer size is now displayed in milliseconds as well as the usual 'levels', and there is now a Cache Size dropdown menu for determining the amount of memory DAE allocates to prebuffer audio for playback and looping when using Elastic Audio. If Digi's Structure sampler is installed, the Playback Engine window now allows you to set a Plugin Streaming Buffer Size to determine the amount of memory DAE allocates for sample playback, and has an option to 'Optimise for Streaming Content', for improved playback of sampler plugin samples from your audio drives.
Elastic Audio is the big story in Pro Tools 7. There have been a significant number of Avid videorelated improvements in all the versions of Pro Tools 7. Support has been added to enable the coinstallation of Avid Xpress Pro The technology behind Elastic Audio is familiar, but the way Digidesign have incorporated it into Pro Tools makes it something special.
Playback Engine Another area of the program that has changed in v7. It is now possible to change the waveform vertical zoom level on individual tracks by Ctrl Windows: Start dragging up or down with the Zoom tool. If you zoom an individual audio track, or group of tracks, the waveform display on that track remains offset when you zoom all tracks, unless you reset the waveform height.
If there are no tracks in the Session, and you import a tickbased audio file, Pro Tools will give you the option of importing the tempo from the file. In Pro Tools HD 7. This is great when you know that the missing files are only fades and so on that can easily be regenerated.
Pro Tools 7. New Video Features There have been a significant number of Avid videorelated improvements in all the versions of Pro Tools 7. Pros Elastic Audio is a lifesaver and very neatly integrated into the program. Should none of these options work, make sure you have done all of the system optimizations on your PC listed in the Getting Started Guide and check the compatibility of your PC.
You may then try to run DigiDriver again. Try these steps before calling Technical Support. Pro Tools LE 7. Simultaneous use of multiple Pro Tools LE hardware devices is not supported. Although limited recording and playback of audio tracks may be possible using the startup drive, one or more separate rpm or faster hard drive or drives dedicated for audio is required for maximum performance and track count.
Please do not activate this feature on any Pro Tools recording drives. Although you may be able to use USB 2. Set "Put the computer to sleep when it is inactive" to Never. If you are using these versions, we recommend you upgrade to one of the supported platforms mentioned previously. There have been rare cases reported where unresolvable issues on Media Center Edition have been fixed by upgrading to Home or Professional. Items in red are recommended for most laptops, and are required for those supported models with Intel Core Duo processors.
Note: Not all Intel Core Duo laptops can be reconfigured with these options, and therefore may report constant buffer errors [, , , , ] when recording. Please contact your computer manufacturer if you need assistance disabling some of the listed options, but realize that we can only fully support the models we have tested.
Also, we strongly recommend that you use a secondary physical hard drive for saving your sessions, audio, and sample libraries to. If you only have one internal system drive C: , then you can purchase an external drive. Note : this may lead to an unsupported configuration when using a laptop with only one FireWire port and a FireWire audio interface, such as the Digi or You may need to purchase a PCMCIA PC or Cardbus Mac expansion FireWire card for an extra FireWire port to run the drive from to attain maximum track count although connecting the drive to the secondary port on the Digi or may work, it is not supported for maximum track count.
Also, though the manual states that the Digi or should be connected to the FireWire port on the back of your drive, this is suggested only to prevent data loss - having the drive connected to the Digi or will have slightly better performance, but you MUST properly remove the drive and turn it off before powering down the We currently only support one model, found here.
Creating a new hardware profile: Right-click on My Computer and select 'Properties. This profile will become the Pro Tools optimized profile, so you can rename it accordingly.
Click Copy to create a duplicate profile before the changes we'll make - this will be your computer's access to the internet and other applications, so name it accordingly as well i. Pro Tools Current and Default. Then make sure that 'Wait until I select a hardware profile' is checked. Close the Hardware Profiles dialog. Disabling non-essential devices: You should be back in the Hardware tab of System Properties - click on Device Manager.
Double-click on the first device listed and select the 'Do not use this device in the current hardware profile disable ' option under Device Usage. Close that device's properties dialog and repeat the last step for the next device listed. All items under Network Adapters, Ports, and any default or built-in soundcard listed under Sound, Video, and Game Controllers should follow suit disabling your network adapters will prevent you from using the internet. Click 'Okay' to go back to the Device Manager.
If you have any external FireWire drives, open the Disk Drives list and right-click on the icon of that drive to select 'Properties. You can now close the Device Manager and go back to the System Properties dialog.
Note: Combined with the previous step, you will now have two Hardware Profiles to choose from during boot. The 'Pro Tools' profile will now have these devices already disabled, whereas the 'Default' profile will not i.
Disabling non-essential startup tasks and services: Click on the Start menu and select 'Run. In the General tab, click the 'Selective Startup' radio button. Uncheck everything but 'Load System Services. It will ask you to restart - do so. Note: If you want to go back to your normal startup, simply run 'msconfig' again and select 'Normal Startup.
Now that you've optimized your computer for running Pro Tools, it's important to check for anything that might be causing a conflict. The next steps can be advanced, so if you are unsure, please e-mail or call Tech Support before continuing. It tells the system how to communicate to all of its hardware; so it's important to not change something if you're unsure of what it does.
That being said, there are several ways to enter the system BIOS, and you can only do so for a short period of time before Windows launches and you have to restart and try again.
Some manufacturers like to set the BIOS entrance key to 'delete' on the keyboard, others use different function keys i. F9, F4, and F2 are common.
Most often, the motherboard will have a "splash-screen" upon boot that will tell you which key to press to enter the BIOS often only referred to as 'Setup' - others, you either have to read the motherboard manual, or guess.
In any case, BIOS manufacturers have their own way of doing things, as should be noted in the general descriptions that will be given for navigating the BIOS itself - without a manual of your specific motherboard handy, I'm limited to a very general framework. With that said, let's enter the BIOS now Unfortunately, this causes erratic and often catastrophic errors with Pro Tools. To disable this feature, find the RAID controller option - it's usually found under the 'Advanced' menu.
Even if RAID is not being utilized, it's important to disable this option. Sometimes it simply shows up as 'speed-stepping. It's usually found under the 'Advanced' tab. Some manufacturers supply their own power management system - please confer with those manufacturers to find the correct option, or follow the step above to bypass their management and turn this off directly from the BIOS.
Disabling this feature may increase stability, but will cut your processors clock speed almost in half to prevent over-heating. Note that not all computers or BIOS will have these options.
Disabling on-board audio: This option simply activates or disables the audio card that's built-in on some motherboards. Disabling the on-board audio can free up resources and prevent IRQ or resource allocation conflicts.
