Thanks for the download!
I'm happy that you got the samples you got.
I've been examining them and here are my thoughts.
The good:
-The samples are accurate
-There are many of them.
-You got a lot of the nuances for each sample correct.
What you need to work on:
-Some of the samples are out of tune. I suggest downloading "Wtune", a Tuning Fork program, and adjusting the base waveforms to a proper note. Alternately, you can use your soundfont creator program and tune the waveform samples in-software by cents. I'm testing the soundfont out and I'm finding that I cannot use the samples in conjunction with other samples because they are out of tune, either too sharp or too flat.
-The sample names do not match their sound. Your "guitar" actually sounds like an Electric Fingered Bass. Your "PianoC" sounds like a Clavichord (Clavi). Your "Tamb" is a timpani. Your "viol" (Violin) is actually String Ensemble. Your 'tuk' (?) is "Pizzicato Strings"), your 'pin' is "Orchestral Harp", Your "Bass" is a Bass, but it's a Synth Bass 1. Your "Tamb2" is a "Melodic Tom". Your 'trompet22' is "Brass Ensemble". Your "??" is an Oboe (but at lower octaves can be an English Horn and Bassoon).
-The sample names do not match their number. They're not standardized yet. This is OK but it would be a cool thing to do for the next version of this soundfont.
Flau (Flute) should be 074
Org (Organ) should be 020
etc.
Here's a link if you want to learn what patch goes to what General MIDI number:
**clicky**@TheCruelAngel: I'm afraid not. The violin you hear at the (awesome) Castlevania64 Intro was played by a real violinist, thus there is no sample for just one note, so you cannot built a soundfont out of it. If you ever beat the game you'll find that the end credits credit the violinist. If a sample in the ROM is found, it would probably be for the entire sequence of the violin played, not just one note.
Of course, if such a sequence were found... people like PHBelmont and I can splice up a few notes out of it and create a violin soundfont...
