From recent videos, it appears that the Iga siren has failed to play the last note of Banjo.

I just read this whole thread! This is very interesting, but I have one question. Would it be possible to actually play the siren with that keyboard? Or is it just for composing? (I am a piano enthusiast and playing a siren sounds so cool!) https://kj7bre.com/assets/images/sirens/yamaha/control-pan...

Being more than one octave and less than two, fourteen notes doesn't make sense... unless Yamaha just wanted their own machine to be bigger and better. Good catch, I didn't even realize! Anyway, I'm quite sure that the 1st generation music siren played some songs that the 2nd generation did. Do we ...

I have a couple of questions and etc. First, the Yamaha Gen. 1 siren seems to show *seven* actuator boxes. Did it have fourteen notes, not twelve? The maximum notes ever found on the 1st generation models was 12 notes, followed by 10, 8, and 4 notes. We've never seen a 14 note 1st generation music ...

During the small stretch of inactivity on this topic, I was able to discover some new locations. Due to all of the 2nd generation music sirens having been found, we're now only searching for the 1st generation. I was sent an image of the music siren locations, 50 locations. Unfortunately, the text r...

I was scrolling through twitter, and a specific tweet caught my eye. https://twitter.com/toyu04_LUGERP08/status/1494222345594339328 The Tenrikyo music sirens, some information on them. The larger 2nd generation music siren was installed in 1988(?), and the slimmer music siren installed in 1990(??). ...

The final 2nd generation siren location has been found! It was located at a factory in Hikari city at the Takeda Pharmaceuticals plant. This location was also a Japanese naval base until After WWII, when the factory was built. It also seems to be the larger siren with 24 notes. Not much else is know...

Introducing the Tono Shinkin Bank! According to a few sources, this line of banks around Nagoya installed and used music sirens in the 1960s. Around the 1980s was when they were inevitably removed. There were at least 3 banks from this brand that used music sirens. The locations of the Nagoya Branch...

[bump] 4 new locations have been found! A few weeks ago around January 13th, a twitter user contacted YAMAHA and asked about the 2nd generation installations. After the locations of install were sent, the user went looking for the locations, and they actually found a location still existent. They al...

If you can manage to map all the sirens in the US, then go right ahead. I would highly advise not though, many people who made theirs official gave up on the project. I, myself, am making a US siren map as well: https://www.google.com/maps/d/u/0/viewer?mid=1PHg_Pg4qoZ0MrCuAAlxlzd3EPx73F8na&ll=43...
