I found this strictly GM only soundfont from an app called "Android Practice Player" or something. It had some not so good choir and synth tones thus I thought on upgrading it as well as putting the other standard drumkits such as "Room", "Power" "Jazz", "Brush", "Simmons" and such, and some ethnic touch with SC-8820 Ethnic and Asia kits

V2.5 - This is the biggest update and also this may be the final version. This is a soundfont that I compiled with high quality presets, mostly made by me, sampled from my Korg Pa700 and Roland JUNO-DS keyboards, everything in less than 1 GB, highlighting balanced and live quality pianos, guitars, basses, and more! Also includes 4 midi demo songs.
