GEM Digital Piano: Why no bluetooth speaker piano output?

Wed, 24 Jan 2024 08:40:42 -0700

Maybe someone can enlighten me... I play keyboards and am considering buying a new one. Although many newer keyboards feature bluetooth connectivity, that feature seems solely included to allow them to interface with an ipad. A feature I would find much more valuable would be the ability to transmit sound output to remote bluetooth speakers. Why is this feature never provided?

GEM Digital Piano: Disposition of keyboard contacts

Fri, 11 Dec 2020 09:47:10 -0700

I’m trying to diagnose a problem with a Gem digital piano, by email, on account of the Accursed Pestilence currently stalking the world.

Like all touch-sensitive keyboards, there are 2 contacts under each key, the speed of travel from one to the other determining the loudness of the note. So with 2 switches (or a 3-position switch) and 2 diodes I shoud be able to make a gadget to simulate one key, to give to the owner in order to test the keyboard scanning logic.

But it’s not clear from the schematic whether both contacts are normally open and both close one after the other as a key is depressed, or, as might be implied by the signal names on the schematic, the first is normally closed and opens, and the second, normally open, closes a fraction of a second later. Or something else.

This may vary from manufacturer to manufacturer, but the keyboard itself seems to be a generic Denon part so it could be that there’s a standard way all touch sensitive keyboards work.

Can anyone enlighten me with actual knowledge or exterience?

When switched on it makes a dreadful noise (sounds like a motor boat)! Does anyone have any circuit diagrams for this model or know where I might obtain the same.

GEM Digital Piano: Piano will not play at all.

I have a Realpiano Grp800. It turns on. You can see one red line on the display, but nothing else and it will not play. Is there anywhere that I can get parts for this piano? It was purchased new in 2009. Seems like the circuit board is done.
