AUDIO DEMO a special demo contribution by David Etheridge with description which also wrotes a very nice article on SOS magazine, now no more online, but we saved it to PDF file. GET IT

demoDevon Sound Track  This is a soundtrack I composed some years ago for a British newspaper covering the Devon area, hence a few nautical quotes which will be obvious musically. At the time, when the video presentation was shown with music, apparently one of the newspaper's directors said 'I didn't know we could afford Rick Wakeman for this" - which was a very nice complement!
The original used an OSCar for the lead synth, plus JX10 brass; I've transferred the sounds to the Pro 2 (Just like a mini and various brass patches), everything is 1000 modules with the exception of the Supertramp electric piano which is from my Yamaha DX5, plus Boss DR660 drums.
demoSamba GX and pro1  A Pat Metheny style samba, using the Metheny library guitar on the GX and Amaysing flute from the Pro 1 for the solo in the middle. DR660 drums again.
demoHall Strings Two Pro 1s This demonstrates the advantages of more than one module; the Hall Strings line is played on one module, and you can hear the notes cutting off as it exceeds the polyphony. Then it's played again using 2 Pro 1s - notice the difference.
demoBig Band Jive Two Pro 2 horns  Big Band Jive using Pro 2 horns, with a smattering of JX10 horns for contrast. DR660 tambourine.
demo Godfather Style Waltz   Featuring acoustic guitars and ensemble and solo strings. DR660 tambourine.
demo Frazier for Big Band   The theme from Frazier for big band. This is a GM MIDI file from the Just Jazz web site, which is a free download. I suspect that it's been sequenced from the Hal Leonard big band library chart!  I changed the GM patch numbers to suitable equivalents on the Pro 1, 2 and GX.  It sounds far better here than on a GM module.
