Another question about samples. Do any of the samplers allow taking the lyric out of a song i.e. can they split an audio track into components so that you can pull out the bits you want to use? Apologies for the noob question.

Quick answer: No
Long answer: No, that's a really tricky batch to actually calculate in a plugin. You mean like karaoke versions of tracks etc?
A sort of 'audio hack' way to do it would be to get 2 versions of the song, one being full vocal, other being instrumental only. Phase flip the instrumental and align both tracks so they are 'in phase'. What happens is the two tracks cancel out when both have the exact opposite signal, leaving a remainder.
Think of the way you wire up a passive sound system (ie a HIFI or surround TV system that has no powered speakers). Now the rules for speakers are positive to positive and negative to negative, to get the sound out properly. But.... if you reverse the wiring of one speaker so +ive is connected to -ive on the amp, and play your audio, when you stand between you get a phasey sort of 'rotated' feeling. One speaker is 'sucking in' (reverse wired) while the other is pushing out. As we read it the other day, speakers are only air pistons if you think about it...
Ok back to the audio example. The flipped instrumental version is our 'incorrectly wired' version, so when we add the total, you'll get a lot of cancelling out signals, and it has been done that some vocal can come through. Take note though, it's not great, can sound very MP3-squelchy or 'alienish', so it's pretty difficult.
We've not looked at the zynaptiq plugins where extraction seems their forté, and we just came across Audionamix too, which do look interesting, and might be an offline system (ie analyse, reveal, fix / edit, bounce out) opposed to a real-time effect.

Ok, so I'm going to go with 'no' as the answer for now. Appreciate the feedback though. If there is eventually something that can do this to a high quality, I'd certainly look at it, otherwise, I'll just have to keep scratching around, or even better, get to know a few singers who can give me some decent samples to play with.
One of the best tools for this is melodyne and even this will not do wonders for very complex or dense mixes. That's because extracting vocals from a busy mix is a little like trying to remove sugar from a tea after it has been dissolved well. (Or like getting pee out of a pool if you prefer a more vulgar expression.)
Not in reason -no sampler does this natively.-but there are other options.ThisIsNotTheMusic wrote:Another question about samples.

Other than previos posts-there are 2 methods which come to mind.
1.Work direct with another artist,or group of artists,and use the multitracked stems-it's how multitracked tape studios always used to record--each player gets a seperate channel.. great for remixing today.
2.Browse the net for emu x3- this old sampler had a specific tool for your purposes,called xtractor.
Qaulity in=qaulity out.
