Ancient Instruments Of The World
This is a soundfont that has many instruments that are almost impossible to find in other free soundfonts.
Shaman Frame Drum
Tin Whistle (Yes, this is in another soundfont, but it wasn't what I wanted for a song I was making.)
Some of the instruments have the word "Continue" after them. This one that is marked as "Continue" is the sound after it starts, a section of sound from the middle of an extended note. This is because it would sound better if you had the one without the word "continue" to play the first note at the beginning and the first note after a rest, and the one with the word "Continue" to play the other notes. To do this, you'd either need a program that supports mid-track instrument changes, or you'd have to have two tracks for the instrument.
how do I select instruments?
In Musescore, you open the mixer and select it from the "Sound" dropdown
This looks very promising!
Can't wait to try 'em as soon
as I get back home!
