I've tried posting to other forums with no help... Can someone please help me figure out how to tune a quite large soundfont with multiple layers. I do have awave studio demo and i own adobe audition. Please help me? (i'd need exact details) If you could even pm me or aim me, just let me know

No shit?

well- what do you mean by tune?

Like using a guitar tuner to get perfect notes, so they can co-exist with other samples. Like I play a piano and the cello samples I have are out of tune with it.

you have to adjust either the pitch f the wav samples in the sf2, or tweak the root note/mapping so that it plays correctly. I have only used NN-XT and Vienna soundfont studio to do this...

What's NN-XT?

Seems that awave studio demo doesnt really let you tweek it realtime, you change the mapping then exit the menu then click on the instrument to test. It's pretty cumbersome and wondered what other methods there were

That's really a simple task.
Normally the soundfont specification (sf2, DLS, ...) includes a "tune parameter" for each sample. This way the multi can be tuned very easy to perfect chromatic tuning with a reference tone (played simultanously and tweaking the tune param of each single sample).

The other possibility is to manipulate the audio data destructive (permanently) with your audio editor. There are infact in every modern sample and soundfont editor tools for analyzing and changing the pitch of audio material (even with Adobe Audition - formerly CoolEdit).
However, this is not recommended, because it can reduce the sonic qualities of your samples (especially the transients of percussive sounds).

Just more difficult, if the pitch of the sample changes in time (which sometimes happened on bad recorded guitar sounds). Then you probably have to apply a pitch envelope to the tone to correct this (either destructive offline or none-destructive in the sampler (realtime). That's more "micro surgical" then if you have no possibility to repeate the sampling with better quality.

mmm I've been working with "viena", the soundfont editor in "Synthfont"... Working pretty well now, except that it has auditioning errors. I've been emailing the author about it

Thanks

Auditioning errors? What's this?

I worked with Vienna years ago (SoundBlaster AWE soundcard). I guess, this editor is still available today...

However, then its quite easy to edit the tune parameter for each sample.

A tip: Try to map a (perfect tuned) simple sine wave with the soundfont you work on temporairly. This helps to find the right sample tuning by auditioning.

If the soundfont is in tune with itself (that is, no bad notes within the font)you could tune the entire font to another instrument using pitch bend. It's not the ideal solution but could work until you can fix the soundfont properly.
