I'm God. Now stfu, sinners.

Please tell me you're not giving up the hardware game Twinny? :'( I'd take these myself, but I know you're on the wrong side of the planet ;)

Welcome aboard JSx :) It's always a good idea to think outside the box and come up with new ideas.... but I have to say, I've never seen any problem like this with any of the hundreds of midi devices I've used. That said, I never used serial-midi on a mac. I think it's more likely an issue with your setup than the MIDI spec ;) Has anyone else seen anything like this which could not be attributed to a particular device's fault?

Nice 1 Phil, keep rolling! Hope you'll share the code and schems and such, when it's all done? :)

The really small one :D Yep same here. It's out by two pixels but as I said, I think that's a glitch. I guess not.

Well I was looking at the graphs, and the big difference in cap values, and I'm figuring that tiny difference is some glitch... so I went back to the schem to reconsider it and refresh my memory... It would appear that the two caps are actually controlling a separate filter mode each. That explains the 'no-pass' bandpass, and why the lowpass seems to be behaving similarly despite the big difference in values, and why they're not acting like a 'chain'.... Might pay to compare the curves between HP and LP...

Yeh I thought that might be it, but there is a difference in the slope even in your image...

I dunno, it looks pretty different in those pics?

Good on you leftwing :D

Heheh okay I think you've been distracted by the example. Forget phantom power, I was just trying to think of some random way that the circuit could get messed with. Point is, I've always felt uncomfortable with exposing the circuit to the outside world any more than necessary... Bad things happen outside the box ;)

Sweet :) Does it have the bootloader on it already?

Well yeh it'll help stop some EMF of course... but what if you apply power to it.... (say, by touching it with a pin from a phantom-powered mic cable that shares a ground with the device) I see the value in shielding, but not in exposing the shield to the outside world, that's the bit I'm stuck on...

That schematic is close enough I guess....I've gotta get around to replying to that other thread.... This'll work (clearly - the wavs sound funky), at the expense of the cutoff frequency slope. So instead of like this: /\ ---' \ \ \ you'll get like this: ,' ---' | \ '., ' (or does it go the other way? Depends which cap is increased and decreased? I don't know, it's too early ;D) Good for some music, bad for sound design. Messes with your harmonics. The bandpass thing, I'm guessing, is the opamps... think of it, rather than one big 2P filter, as a chain of 2 separate 1P filters.

You can do that in your application, and you should.

Explains why they don't trust you then ;)

And the Echo Gina/Layla(24/3G), and heaps of stuff with ADAT. It's far from rare ;)

Well, the form factor is a side-effect of the method of construction. The name refers to the method of construction.

Easy for you and I to say.... not everyone has soldering experience like you do ;) SMD's not so bad though... nothing a little bit of practice won't help :)

You cut out the important part: instead you can buy a preprogrammed PIC18F452 from SmashTV or Mike, or you can ask a friend or a member of the MIDIbox Forum who already owns a PIC programmer for burning the firmware into the PIC (the memory image can be downloaded from this page). It's like this: Blank PIC from an electronics shop... Use a burner/jdm to put the bootloader on it.... (if you buy your PIC from smashtv, these last two are done) now you can upload apps via MIDI, and you dont need to burn the PIC again. If you have a bank account, then you can get a debit card, and use that to put money in a paypal account.

Why is that? (not arguing - hoping for a lesson :) )

Cool :)

You're right I totally did. I'm with you now. >Insert screeching brakes noise here< ;D Thanks Twinny. Hope it doesn't end up with a restore!

LOL!

Damn, durisian, I thought I typed a lot! :D I like the idea of using templates like that to get some structure. I think the only section missing there, is the "How to build a [mbsid,mbfm,mblc,mbseq,etc]" , which allows a start-to-finish document. I guess it would go after the 'skills/equipment req'd' section, and each one would be a similar set of headings to the generalised 'hardware' section. Thanks for your effort man!

http://sg.farnell.com/1212704/semiconductors-integrated-circuits/product.us0?sku=microchip-pic18f4620-i-p I'm pretty sure al the aussie orders come from these guys ;) Do you have a burner or JDM? You'll need one to put MIOS on the PIC.
