Hey megadrummers. My name is Jay. I'm a Canadian and am new to the forum and am wanting to make a megadrum module. I'd like to burn my own PCB unless synthex sells pcb's without the parts - synthex? Anyway, I was going to use Dmitri's PCB layout for the 32 input analogue board but then I got to thinking that bigger is usually better - so with a bit of Dmitri's help I've edited the supplied KiCad schematic to include the 3 new mux's, all their included resistors and bats and a 2nd 40 pin connector (cause I've got tons of old 40 wire IDE ribbons kicking around). Anyway, I have no idea how to go about generating a PCB from the schematic. Is it automatically generated or do I have to draw the entire thing out? Also, I have no idea if what I'm doing is right. I was into electronics waaaaaaay in the past so I'm pretty rusty and mistakes are easily made. If anyone wants to check this over and help me make a new analog board pcb to handle 56 inputs then lets rock!

The one thing I am unsure about is my routing to the 2x20 connector. I'm thinking that there would be a way to optimize what went where for a cleaner PCB.

Anyway any help would be appreciated guys. Also if this has already been done, my bad - I looked my didn't find.

OK, I annotated the sch myself which I am finding does not work when you try to output a netlist to cvpcb. When I clear the annotation and have it automatically annotate, it does not seem to see the bats. Am I missing a library or something? When I load Dmitri's original files I get a long list of missing libs, one of them being diodes, so maybe thats why I can't seem to get past this point. Hmmm...I don't really have the time to learn the quirks of an entire suite of tools so maybe I'll have to give this one up and just burn the 32 input board. Hmmmmm....

Should this be in a different section of the forum? Dmitri?

As far as I can see it belongs here.
