How is CEP equipped for hands free multiple overdubs of a region? This is where the machine does an auto-shuttle rewind-play cycle and lets you record a number of over-dub tracks automatically, within the specified region. Tongue

Enable multiple takes and enable the loop button on the transport whilst recording?

Nice idea. Unfortunately the loop button only works for playback mode. Wonder what it would take to program it for recording multiple takes as well?

Another one for the wish-list!

Pro Tools? Wuzzat? Cool

Definely one for the wish list. A standard modern recording tool really. I was just hunting for this feature in order to average a number of impulses. This is to remove pc fan noise and thermal noise etc. from the impulse recording. It takes about 20 to 100 'takes' to get a very clean acurate impulse record.

For now i will have to make a script i guess. I hate arming tracks by hand. Dead

Sounds like there's more to this than meets the eye.... you're trying to record impulses in the same room as the computer, with it running? Have I got that right? In any event, maybe recording them into one long file and cue marking the start of each take might be another way, or using the "Auto Cue" function might work (forgive me if these are silly suggestions, I'm thinking aloud). Alternatively, a different recording application altogether might work - one with a "vox" function which starts to record when it hears a sound, and stops afterwards - 'Audiomagic' for instance.

I'm getting clean, noise free impulses of my 'control room' (if you can call it that) by averaging a very large number of recordings of the same impulse with the mic. in the same position each time. There's a bit of machine noise in the air, and noise in the mic and preamp and D/A, A/D converters that all add noise to the impulse file, so this removes it. I mix-down all the takes and normalize to create a file with the noise averaged out. Problem is it takes a lot of 'takes'. This can be used to remove preamp hiss from re-recorded guitar amps too, i'm hoping. 8)

Your idea about auto-cue might be just the way for now! Tnx! i'll check it out. Big Grin

All you have to do (with CEP 2.0 or 2.1) is right-click the record button in Multitrack. Then you will have the option to loop-record. However, normally this will just record over what you've allready recorded, so you will want to do something like "punch in" or "allow multiple takes".

Hope it helps!

Well shiver my timbers! I'd never spotted that before. So you could create a template with, say, an hour-long "insert empty wave" and then loop record into it to capture the last hour of a radio station or whatever in case they played that single you've been wanting to hear again for the last 20 years?

Or, more usefully, this would appear to get around file size limitations on long recordings - looping would seem to allow you to automatically start a new file every however-many-minutes you want - which I know would be of interest to some here (MC?!).

And I note it's clearly there in the help file in the transport control section..... tch tch, I must read it again!

That is great! Thanks Pro_Support! Cool

You just select "allow multiple takes" in block properties, and choose one of the 'loop' options in the main record button. It numbers the takes and stacks them in the files section. I select them all and insert into muti-track, mix to a file or track and normanize. Approve

Hey Oz, ya good point. That will make recording live events so much easier and better. 8)

I guess there's a little snick between takes/files, but to get rid of this you can open two instances of CEP and stagger the start times for each, so at least one instance captures each moment without a snick. Approve

That takes twice as many tracks, but for lots of tracks like for live multi-tracking, two PCs running CEP can be syncronized.

Or maybe there's a way to banish the snick. That would be best of all. Evil

Yea, it's an almost-there thing - there is a tiny loss of data as the cursor goes back and a new file is created. The usefulness of this as a means of continuous recording (given that there are 3rd party alternatives) might depend on the application. Still, it's good to know about!

This is nice to know! I saw the link over at www.audiomasters.org . Thanks Oz! Wink
