I created a virtual instrument using these samples of a Rickenbacker 4001 bass guitar and decided to test it out. I also made a trumpet soundfont. This is the result of my machinations.
Testing out a kettle drums VST, I came up with an orchestral piece. Plugins used (all free for download) Kettle Drums by Samsara Cycle Audio: http://www.vst4free.com/free_vst.php?plugin=Kettle_Drum&id=1860 VSCO 2 Percussion and VSCO Orchestra (includes percussion) by Big Cat Instruments: http://bigcatinstruments.blogspot.com/ Cymbalistic and Hand Crash by Alan ViSTa: http://www.alanvista.com/
Three loops were obtained from prodmac10 on looperman.com I composed the bass, drums, Rhodes e-piano, and high octave guitar solo, and did the effects, mixing, and mastering.
