The folks from ProducerLoops.com (in the UK) are giving awaya free 1GB loop pack in ACID, AIFF and MIDI, including .OMF arrangements (think ProTools).
And they have a bunch of other products on special!
“This Kit we are giving away for free is based on a composition named “Arabian Groove” which can be found in the full version of Symphonic Series Vol 2: Arabian Adventures 1. It’s got a rich Western orchestral sound playing typical Arabic melodic lines. No chords are included as authentic Arabic music is based on melody and rhythm rather than on harmony.”
