Eawpats is abandoned, but it has been sort of reborn as FreePats (freepats.opensrc.org). Half of the patches in eawpats are derived from original Gravis patches, and therefore may have some intellectual property issues. Because of this, and also because the bandwidth costs were getting to be too high for the ISP to continue to eat for free out of the goodness of his heart, eawpats was discontinued. The Gravis patches were stripped out and rereleased as Freepats, with a few improvements over the last eawpats release, and a few Gravis patches replaced with new good sounding samples.
