 |  | The attached scripts are a quick and dirty fix. Put them in a
 |  | temporary directory along with a copy of the soundfont, like this:
 |  |
 |  | fixpan.rb
 |  | fixpan.sh
 |  | Steinway_IMIS2_backup.sf2
 |  |
 |  | Then run fixpan.sh. It will produce Steinway_IMIS2.sf2 with panning
 |  | reversed (and many temporary files that can be deleted). Those scripts
 |  | use pysf, so you will need to have it installed.
 |
 | Hi, i downloaded pysf from:
 |
 |
 | http://terrorpin.net/~ben/docs/alt/music/soundfont/pysf-wip/pysf.py
 |
 | chmod +x pysf
 | chmod +x fixpan.sh
 |
 |
 | Then I executed fixpan.sh
 |
 |
 |  ls -lah *.sf2

 |
 | It works
 |
 |
 | It's nice to work together.
 |
 | Well, I must fix some some overlaping issues, volumes and so..
 |
 |
 | I added the fix scripts here:
 |
 | ftp://musix.ourproject.org/pub/musix/sf2/fixes
 |
 | ftp://musix.ourproject.org/pub/musix/sf2/fixes/README_fixpan.txt
 |
 | etc.
 |
 |
 |
 |
 | Best wishes


Well

Note: you can apply this patch to the soundfont by using:

= Steinway_IMIS2.1.xml =

* Applied the fixpan.sh script made by Roberto Gordo Saez to reverse panning 
all the samples. Thanks.

* Fixed some layer overlaping issues (about 6 or 7 errors)

* Changed some sample key note ranges to get a more homogeneous sound

* Fixed some important volume issues: 
	- now the mf layer is -6db  attenuated, not -12db  attenuated as before
	-  attenuated the C7 FF, G7 FF, C8 FF volumes and some other samples too



TO DO: 

* There is too much difference between E1 and F1 in the FF layer: E1 is too 
bright, and F1 is too opaque

* Test: we need to know the best ranges (settings) for the MF (opaque) and FF 
(bright) layers, maybe it would be fine to lower the FF range, so you dont 
have to press the keys using too much intensity (MIDi velocity) to get a 
bright sound

* Change the mf layer attenuation to -8db or so? What could be the best 
attenuation?

* Add more samples?, for instance:  Piano.ff.Db2.aif Piano.mf.Db2.aif 
Piano.mf.Ab2.aif Piano.ff.Ab2.aif Piano.mf.Db1.aif Piano.ff.Db1.aif 
Piano.mf.Eb1.aif Piano.ff.Eb1.aif
	- This could solve some heterogeneous sound problems

* Add the PP layer? (it needs a hard denoise work)

* Test some reverb settings (do we need to add some little reverb to the MF 
layer?) FF layer has 20% reverb. If you use Qsynth, you can set the reverb 
for the FF layer, but the MF layer will not sound with reverb. I did this 
because I think that when you play and acoustic piano at high intensity it 
producess more reverb

* Get a more overall heterogeneous sound

* ??
