We will load a USB Flash drive with 25 piano/organ accompaniment MP3 files. Simply insert the Piano Organ Flash into a USB port on a personal computer and you can copy and play the files in your services as needed. Please note: Multiple flash drive orders (such as ordering volumes 1 and 2) will be loaded on one single flash drive. If you happen to require separate flash drives for separate flash items, please indicate that in your order comment during checkout. Order high keys or low. Order both and we'll load both on your thumb drive for just $4 more.
