This is an amazing app, and I’m really pleased with it. I’ve already published 2 songs, using this app for the plucks. Thank you again.",

"title": "Great dark and eerie sounds",
"body": "Though the instrument controls are fairly basic, I love the sounds from this instrument. They fit the style of music that I like to play very well. I would love to see more sounds added to the instrument over time (even if they require a small IAP). My biggest challenge with the Backrooms Piano is that it doesn’t support the sustain pedal at all, which makes properly playing a *piano* quite a problem. If the keys are held down they ring out properly, but sustain pedal MIDI messages are simply ignored. This would be a far more usable instrument if the sustain pedal was fixed. Thanks!",

More presets and improvements are on the way."
