Massive YM2413 Sample Pack (245 Samples)
http://little-scale.blogspot.com/2009/10/massive-ym2413-sample-pack-245-samples.html

I have recorded a sample pack from a real YM2413 chip.

The sample pack consists on 245 samples. These are:
• 5 drum sounds
• 16 sounds per instrument, across 15 preset instruments

In the case of all of the pitched sounds, the samples include every C and G pitch from C-2 to G6 (16 in total). Every even-numbered file is a G. Every odd-numbered file is a C.
