So I have this crazy idea to build this piano amp and speaker. This might not sound crazy if you do it with batteries on the safe side. So lets put the twist on it.
I owe a lot to two credit cards. I am going to put down $150 on the two credit cards a month and try to spend less then $50 a month on this project.
Oh by the way my piano is MIDI. So It will use a midi interface and cube base to run it. Unless one of you on this forum has A schematic of a circuit that will process MIDI signals. Which is the term synchronous in micro programming. That means you will need to provide me with a program written in PBP3 or a hex file if you have secrets to hide.
Let me get this strait I am not expecting any of you to know how to program but it would be nice.
So here is the set up. 10 Band EQ on each side and then a filter for up to 6 speakers for Lows "Bass," mids, and highs also known as a tweeter. Here is the only rule the only thing that can run on alternating current in this is the computer. My interface is powered by usb alone so that leaves the amp 10 band eQ only on batteries. Oh and if you have a good power amp schematic that uses a chip that will help because the schematic I have is from a book and it might be copyright if posted here.
If no one has interest in this it means that this was a shot in the dark. I was just curious as to what you might think
Parts list to go by;
TEA2025B amp
TL074CN TL074 Low Noise JFET Quad Op-Amp

Power amp will be posted in my next post

:blink: None of that makes any sense to me, but I wish you luck with you project! Hopefully someone less clueless than me will be able to help!

Ditto for me, I don't understand musical electronics, and that is a lot of very technical talk that the average pony won't understand.

Sounds interesting! Good luck!

LOL
Well every one has their talents and That is what makes society so interesting. Thanks for replying thought I would just throw a marble in a bowl and watch it go round and round. So who is the bowl and who is the marble?

I lost my marbles long ago so I doubt I'm either.
