Several Variations on J.S. Bach's Air on the G String

This piece, Air on the G String, by Johann Sebastian Bach, from his Orchestral Suite No. 3 in D Major, is a Musicnotes Special Edition, purchased from Musicnotes, Inc.. Their Musicnotes Special Editions are printable sheet music, which include rights to perform, record and print multiple copies. I have sequenced this entire piece, using Noteworthy Composer, running on an old Windows XP computer. Noteworthy Composer plays the piece through an M-Audio USB MIDISport Uno bus-powered MIDI interface, to a MOTU Timepiece AV, which routes the MIDI channels to four separate Roland Sound Modules, specifically two U-110's, one Orchestral M-OC1, and one Dance M-DC1. The audio output from the sound modules, for this piece, is passed through a DigiTech Studio Quad multi-effects processor, and then goes to a Roland VS-1680 24-bit, 16-track Digital Studio Workstation. The audio tracks are saved with a sample rate of 44.1k, the same as an audio cd; and at an audio bit depth of 24-bit, DVD-audio quality. CD audio is a bit depth of 16-bits, for comparison. The tracks are then mixed down via an optical audio (Toslink) interface to an old Apple Power Mac Dual-processor 2GHz G5 computer, using Bias (Berkley Integrated Audio Software) Peak LE Version 5.2.1. The final AIFF file is then converted to MP3 format using iTunes.

While this piece, as I recorded it, is over 4 minutes long, I have snipped the tracks down to under one minute in length, to provide a sample of the instrument combinations.

My first variation of this piano piece, by J.S. Bach, is performed using one Roland Sound Module, the U-110. The patch playing is patch an internal patch, I-57, guitar and piano. The audio is then routed through a DigiTech Studio Quad, 4-in/4-out Multi-effects processor, using their factory patch #36, Mono In Delay - Triplets, for one voice of the output.

My second variation of this piano piece, by J.S. Bach, is performed using two Roland Sound Modules, the U-110 for the left-hand staff, and the M-DC1 for the right-hand staff. The patch playing on the U-110 is an internal patch, I-20, slap bass; on the M-DC1, it is an internal patch, P-102, Dance Guitar. The lead audio (right-hand) is then routed through a DigiTech Studio Quad, 4-in/4-out Multi-effects processor, using their factory patch #36, Mono In Delay - Triplets, for one voice of the output.
