Four ambient pads built from layered choir, organ, Juno, and ambient pad samples run through tape delays and reverb pedals. Ambient Pads Vol 1 includes the following packs (which can also be purchased separately): Angel Pad, Cathedral Pad, Feedback Pad and Organ Choir Pad. All four packs includes 12 minute long Wav and MP3 files in all 12 keys. These work great as song transitions, or an ambient drone that fills out a song. Full description below.
