yes, all of my MLP covers will be Derpibooru exclusive

The theatre organ sounds I’m using is indeed based on Wurlitzer. My keyboard, Yamaha PSR-SX700, has a complete collection of theatre organ and electronic organ sounds. It also has a feature called “Organ Flutes” which simulates the bars seen on an actual organ. Here’s what they look like on the PSR:

The theatre organ section even has complete collection of different pipe types (Tibia, Vox, Trumpet, Kinura, Reed and Diapason). The glockenspiel and piano layers are available too.

Fun fact: Theatre organs are actually the ancestors of modern electronic keyboards that can play different sounds. In the 1980s, there is this organ called Lowrey which also go on to inspire the likes of Yamaha PSR family of auto accompaniment keyboard

Based on the fact that the musician that made this song also uploaded it (user4897), I would say this counts as an original piece and a Derpibooru exclusive. After all, it isn’t like it was uploaded to any other site, since there is no link for any other website included.

Is this an original piece? Is it a Derpibooru exclusive?

Honestly, I like this. Kind of reminds me of the twin console Wurlitzer theatre organ near me in Denver that somehow was never removed and still gets used for concert performances from time to time. Theatre organs are very unique instruments, and it’s a shame that there’s so few of them left thanks to the arrival of ‘talkies’ in the 1930s largely rendering them obsolete inside cinemas (and the arrival of Walt Disney’s own ‘Fantasound’ for Fantasia further cemented this fact). The select few that remain, including Denver’s Wurlitzer and the two organs found inside Radio City Music Hall in Manhattan are only still there thanks to a concerted effort for preservation inside both of those venues. I hope they continue to be used for performances for many years to come.
Once again, so nice to see you making a track based on those wonderful instruments. Sadly, organs are typically not instruments used for music covers, so this is very nice to see indeed.
