They are directly related if you switch automation to ON by right clicking on the automation button above each track fader. That is write or touch or just read when automation has already been written.

When automation is set to one of the write modes moving the track fader during replay will cause the track volume envelope to reflect the movements made on the fader. When you replay through a section where automation has been written the level of the audio on the tracks will change as does the volume envelope.

If you also set 'Show Automation' to ON the track fader will move during replay to reflect the changes in the volume envelope.

There isn't any need to change the automation mode back to 'read' when replaying, except as a safety measure to avoid accidental changes in our automation, as the volume envelope will be in read mode until you touch the track fader, or in my case my external mixer. The track faders are also duplicated in the mixer window which has only been introduced in Vegas Pro 8.

More info on how you automate your mix, including plugins, is available in the Vegas Help files.

Thanks newhope,

But I was thinking more in terms of : if I put an envelope into a track, if i set the fader to -6Db and then set a marker of -6Db on the volume envelope, does that mean that point have a level of -12Db

How do they related to each other when each one is set to values -- assuming the automation stuff you mentioned is turned off.

I assume this same relationship exists in Acid products as well.

Thanks,

An interesting question which I can't answer at present becuase I'm booted into Mac OSX. Mind you, it isn't something I would do as a professional audio mixer. Basically, as you have a range of around -60dB of volume reduction I'd be set one or the other, but not both as, if they are additivie, which I seriously doubt, that method of operation just leads to further confusion down the track.

So, setting one or the other to -12dB, if that is what you want to achieve is a better way of achieving a level reduction....

Edited after Geoff's reply... as I said I wasn't booted into Windows and therefore couldn't test it myself. Geoff thanks for correcting my error... I couldn't imagine that Vegas would do that.

It's a fairly weird way of doing things which could lead to basic errors in gain stages i.e. dropping the envelope level while raising the fader could cancel the affect each was individually creating. Hence dropping the envelope level by -6dB and raising the track fader by +6dB would result in a null effect on the level = 0dB of change.

As I said above it's something you really want to try to avoid in general and be VERY aware if you choose to operate in that manner.

In normal (non-automation) mode, the track fader comes after the Normalisation switch, and before any Volume Envelope. So with the track fader on -6dB, then the 0dB level 'start point' on the evelope will be -6dB. Pulling the envelope down -6dB will give a total -12dB.

This is pretyy clearly explained in the Help and Manual. And you can confirm this for yourself in about 30 seconds (if you have Vegas in front of you). Easiest with a steady tone.

Yes, you would have a level of -12 dB.

The faders in Vegas (and ACID) have two uses.

Trim Control: This is the mode with automation turned off on a track or bus. You are setting an overall gain value to the channel.

Envelope/Automation: There is no difference between the concept of an envelope and automation. They are the same. Envelopes represent automation of parameters. The fader allows you to write envelope data when a track or bus is in automation mode. A track/bus in automation mode is just a different way to create envelope data.

How do they related to each other when each one is set to values -- assuming the automation stuff you mentioned is turned off.

Trim + Envelop = overall gain.

Thank you all. Much clearer now (and yes, I *should* have read the Help files)
