I am creating a YouTube channel for people to be able to sample piano sounds from various devices and voice packs and I am trying to give as much information for each as possible.
https://www.youtube.com/channel/UCLTcNMjqSXgt8yyQqhr1r1w

I would like to provide the source for samples for every piano I demonstrate there. Currently of all the piano sounds I have, the only one whose source piano I don’t know is the Upright Piano for the Yamaha MONTAGE.
Note that I have listed it as Unknown here: https://www.youtube.com/watch?v=RR-WySsHmbo

Can anyone tell me what real piano was sampled for the Upright Piano for the Yamaha MONTAGE?
It feels like a stain on my series of videos to have full information on every piano but that one.

Of note there are many many more videos to be posted of piano sounds from many sources (probably about 100 more videos to go). So I am also open to any kind of feedback while I am still early in the stages of the channel. Any other information people think would be useful to go with each video etc.

Regards,
L. Spiro
