I would have to agree its a mess, I hope they can do better!The littlebits website you posted the link to seems about as well designed as the circuit you posted, more a random series of unconnected pictures than anything else?.
Square wave in.....square wave out.....works "OK"Ron, How would it look with a square or saw wave input? Thats what the oscillators that come with it make.
Wow I find it hard to believe its that poor of a design.
Can you point out an audio defect that I should be able to hear?
How hard would it be to improve it? and what advantages would the improvements provide?
So Vref on the audio opamp sets the center voltage to 2.5 volts, so its all above 0 volts.
What about the rest of my assumptions?Only the AC coupled amp in the middle is biased correctly.
Yes but that would not work with the DC component as well.Simple mixer: Supply is +6V and -6V
Note input and output is AC coupled to strip off any DC.
It could work with +6 volt supply, and with "gnd" connected to 1/2 supply. (vref)

Your speaker can not pass DC. Your ear can not hear DC. Don't bother with the DC.Yes but that would not work with the DC component as well.

Nigel its true! it has been posted all of the internet , in the electro sound forums and such.I'm EXTREMELY dubious about claims that Korg helped develop it. I don't believe they would have anything to do with such a poor effort.
And that was one of the challenges for this system that they overcame.Notice Ron's post #29, that's how a simple mixer should look - and 'could' be made DC just as easily, but as it destroys the operating conditions for AC then it's not something which is ever done.
