SFontEditor - Editing

Editing a .pset file:
   Note that .pset files are just text files.
________________________________________________________________________________

Ok.  Background time...
      Many musicians go through a synth's factory presets
      and pick out the good ones.
      Sometimes, they don't even TRY to create NEW ones!!
      That's just sooooo WROOOONG!

   The preset controls how the sample is dumped through
      the audio path of the synth

      It gives life to aftertouch and the mod wheel and pitch bender and
         pedal and... (insert other controls here)

   So find a good soundfont sound using PianoCheater,
      load it into SFontEditor to see what makes it tick.

   The .WAV samples will likely be most of the sound's beauty.
   But it might just be the
      - oscillator detuning
      - frequency filtering / resonance
      - amplitude envelope
      - LFO'ing
      - effect params
      that the preset parameters control that make the sound shine.

   You can do a LOT with simple waveforms (not to mention complex ones)
      if you make em change via different controls.
      For example,
         lower velocity could filter the sound to "muffle" it a bit.
         So it plays bright upon strong velocities and mellow for low ones.

   Most presets just have the mod wheel modulate the pitch - laaame.
      Make the mod wheel do something ELSE!  Have it control an LFO that pans.

   Read up on sound synthesis techniques and
      make the controls that you've got do COOL things to the sound.
      Not just sit there and do boring tremelo or vibrato - bleh :P

   Ok.  Enough background.

Load a sound into SFontEditor and see what params it has.
   Try tweaking it.
   And save your changes as a NEW file so you still can use the old sound.

   After saving a new preset, make sure you do "Gluing" again to
      add it to PianoCheater's list of sounds.

   Goof around and let me know where you get confused.
      (Can you tell I'm still workin on these docs:)

What the heck IS a soundfont preset???

Ok.  Soundfont presets are a pretty detailed beast.

Creative has a (somewhat ok, mostly lame) tutorial
   here
   specs here
   It covers not just presets, but the whole SF2 file format.
   You may want to avert your eyes.  Seriously.  ;)

I'm not sure I can fully document it WELL yet, but I'll give you a starter :/
   If you're familiar with editing sound presets,
   you just might recognize most of the params.

Soundfont presets have the top preset level that references
   instrument level params which ref
      sample level params

Samples have their own set of params.
   Preset params sometimes replace, sometimes modify Instrument level params.
   (sometimes - it's confusing:)

In addition, GLOBAL params are at the inst and preset level
   which can be overridden as well.

Here's an example...  It's all I can do for ya right now - sorry :)

   gen=val
   mod=ctrl[mod]+ctrl[mod]*amt
InstName (or path\WAVfilename for a no gen/mod instrument)
   gen=val
   mod=ctrl[mod]+ctrl[mod]*amt
