How to Totally Control Sample Playback In EXS24?

This might be a completely stupid question, but up until now I haven't got a workable answer to it.

The thing is this. I sample a sound, let's say a horn stab. OK. I want to be able to play it higher and lower.
OK again, the EXS24 enables me to do it, as would any other sampler worth its salt. But what also happens is that the higher sounds gets played so much faster, and the lower sounds so much slower, that it would be artistic suicide to incorporate them in a track, unless you want to be the Schönberg of electronic music or develop an innovative car alarm that immediately kills the perpetrator by blasting out excruciating soundwaves.

Is there anybody here who can enlighten me about the strategy to lower and higher the sample pitch without
speeding or slowing it down too much? Or am I asking a supremely ignorant question and is the only way to higher or lower a sound by speeding it up or slowing it down?

what you do is create multisamples of that instrument.
for each C note another sample, or, better yet, for each note another sample, or even better... different samples for each velocity (usually 4 layers) for each note.

there's software to do this automatically (since it's a lot of work, obviously)
probably will be in the next incarnation of Logic
Best Automated Sampling software to capture Hardware instruments.

Aha! So if I have only one sample of the specific sound, I'm bound to have this aggravation? I would love to have a Single Source Sample Spreader in the next Logic incarnation.Thanks for your answer Reptil!

no, you can have pitchshift software (also within Logic) that doesn't change the length of the samples. you'd have to resample presumably.
RTFM it's all in there.

Yeah you're right. I should at least have been thinking a little bit deeper.
So thanks to your advise my current thinking is that this does the trick:
1. Pitchshift your sample for each semitone 2. Bounce these as separate audio files 4. Drop the totality in EXS24, and there you are.

yes, if you have no access to the original source (and cannot play and record each note)

If you need this functionality often enough, then you may want to think about investing in a sampler plugin that can do it automatically. Kontakt and MachFive v3 come to mind, but there may be others I'm not aware of.

Or since Apple just acquired Redmatica (Keymap Pro could create such programs), perhaps their tech will find its way into Logic 10.

Remember though, if you use pitchshifting you're likely to introduce bad artifacts into the sound, however good the algorithm you use is. Also, instruments like trumpets don't sound exactly the same whatever note you play, so simply pitchshifting won't give you a realistic sounding sample instrument. Far better to multisample (take multiple samples of the trumpet at different pitches).

yep... i'd be wary of this, the limitations you found with the speeding/slowing stuff will also be there with any technique/software that tries to turn a single trumpet note into a whole trumpet set of octaves.
