They were plenty of challenges with this piano.
I wanted all bullet ticked:
- Cheap
- Big but could fit in a car (from 1 to 8 meters long)
- Expandable (from 1 to 8 octaves now)
- Strong (it's for kids, even if adults love to play too)
- No moving parts (same reason as above)
- Easy to use.
Fascinating project. 👍 I've seen fun videos of similar keyboards. What would be really great would be polyphony, to allow a few people, maybe even a SATB ensemble, to play together. The keyboard may have to be broader so that several players can hop on it.
Pity humans have only two feet so cannot play triads. 😜 United there is some kind of sustain. 🤔
