SSP, I thought I had explained it already? Yes, it's doable, and yes, we'll help you with the source code ;-)

You won't kill yourself but you might kill your core's VREG. Typically you'd wanna feed it with 7V - 10V. If you have a heatsink on your 7805 and preferably no CS this might well work, but the 7805 will get pretty warm. What you can to is to put an 7809 (+ caps) in between the +12V and J1 of the core. Grounds go together. Do that as close to the psu as possible and only once (star-wiring).

Wilba and I have ruled that out already. This is all very odd ;) This is an issue that I had recently as well (after upgrading to version 1d). Only happens very rarely and only after the initial powerup, so a power off-on cycle fixes it. I haven't had a closer look at what might cause that tough.

This is technically doable (worst case: with some extra programming) but why? A range from 0..127 is not that big that you'll have noooo idea where you are on a fader. The fader itself is pretty good visual feedback...

Psychology at its best ;)

Did you check the price? Usually for one-offs at that size shipping your own material is gonna be more expensive than getting the whole thing from them.

Discovery is. That's the point. By posting the answer you ruin the fun of discovering it for everyone else.

I've always admired the soldering info on that page ;)

Well let's at least mirror what's there so far ;) MidiBoxCV-Doku-de.pdf MidiBoxCV-Doku-de.pdf

6N138s are kinda sensistive and a fair component to blame when MIDI In isn't working. Get a new one (they're not that hard to find) and this time - socket it and never ever ever solder an opto-coupler without sockets again. Actually - unless you have an incredibly good reason to never ever ever solder an IC, but always use sockets.

32 pots and 160 buttons is well possible with a pic based cored. Search for "matrix" ;)

That's correct actually pin #24 is potx and I am not sure about what voltage it should/could have. 14 Vss - 28 Vdd should be 12V as you measured. Check your soldering. Better yet - post pictures.

Obviously there's a problem with the supply, eh? ;) SIDs don't run w/o power. What PSU are you using?

Jamming with my dad when I was barely able to hold the blue harp did it for me, so I think cimo's on the right track ;)

??? How did that happen?

Hehe =) Na gerne doch!

Additive Farbmischung: grün + blau = cyan ;) Eine der ekligsten Farben die es gibt. Fast nur noch zu toppen durch magenta.

HULK LIKES!

Yeh, same here, I wanted 114 and Wilba was a total pain about it *whack*

It runs smoothly under Wine as well so most *nixes are covered as well.

Vedge: That's good thing to do - if you look at the pokey board I have a software controllable clock divider on it, which comes in handy for octave shifting and other fun stuff. The chips are pretty stable at all sorts of different clock speeds.

We did understand what he tried to say - it's not the point of what we're saying though - if you can afford em, buy em regardless of where you are.
