"This was overall a fun build. I have been having a bad run of luck lately with my last 5 builds missing pieces. Fortunately this go around there was only one missing piece.
Once the model is completed it's pretty beautiful. I have two minor gripes. My gold bars that represent the strings more bent when packing. I've tried to bend them back but it causes a hammers on the strings to get stuck. Not that big a deal I can live with it.
@Lego please consider adding a rubber band or something to slightly extend the Technic piece that stops the key motor from turning backwards and a certain point (resets the key position). Pressing the button application to reset the keys , the gears over rotate slightly because the stopping Technic pieces not long enough by a cm. So the keys are never flush when you reset them. Not being able to make the keys level detract from the beauty of this set. It seems like it would be a simple fix.
I do hope they will add more music to the application.If there's ever a version 2 of this piano, would it be possible to add light sensors to every single key? By doing this the application can know exactly what key was pressed and what sound that key should make. However this may make the sent extremely expensive. There may not be enough room in the piano to have 25 individual sensors.
The finished product is beautiful and display well. Even with the minor issues it was a lot of fun. In the end you won't be disappointed with with this model.
