Putting audio cards in a MIDIBox?

[moogah]

This blows my mind.  Perhaps I'm thinkin this does more than is actually possible.  How are people doing this?  I though the PIC couldn't work with audio?

[raphael]

What audio cards ???

[moebius]

They just put an audio card in the midibox. Simple as that.

Bye, Moebius

I'm putting an audiocard into the one I'm building. It doesn't interface with mbhp in any way - just a shared power supply. The idea is just so that I only have to cart 1 box about instead of 2. I managed to get a B stock Firewire audiophile - only had 3 months warranty on it but what the heck - I'm ripping it apart anyway. Sure beats the risk of lugging my MOTU about  :)

Huh ???

who is doing this and where can I look at an example?

I asked:

Hey moebius,

For me a "card" is something with PIC/ISA bus. That's why i was asking....

For example bcbox integrates a M-Audio firewire interface:

But only the MIDI part is connected to the MidiBox core, the audio part is standalone...

Sorry, misunderstood.

I thought it was a sound card directly connected to a midibox....

i have been working with windowsXP embedded, joining my midiboxes with dedicated windowsXP system, attempting to increase response. the only multimedia drivers are sound/display related. No cdrom drivers, no games, no office applications.  Just java/OS/hardware interface to midibox. Response time is good.  Works really good with my midiboxMOOGModular worksurface.

but..... it would be nice to be able to hook sound cards into a midibox (don't really think the pic is fast enough)

No, PIC is way too slow...

Just compare:

PIC works with 10MHz (40MHz internal).

PCI-Bus (for Sundcards) works at 33MHz.

I know only one project to use a ISA-Networkcard with PIC... no soundcards.

I know this is off topic but.. it sounds like you have been involved with the JAL ethernet project.  ;D

JAL/ethernet works for me and my robotics projects  :)

.... Isn't the audiophile a PCI card?  I still don't quite get what is going on....

[Steven_C]

be wary of emc/noise when putting any analogue audio near a running PIC. I learnt the hard way!

No, I`m not involved. I just saw the JAL project on the net and a friend of mine uses it for some home automation stuff.

If you read the text carefully, you will notice that bcbox uses a "M-Audio Firewire Audiophile"

This is no PCI card. It`s hooked up to your computer via Firewire.

[Tanstaafl]

ahhh... understood.

somehow I misread what was going on.

I thought I read that we were  replacing/bypassing  the PC.

(which would not be a bad thing, in my book)

Hmm..

I remember there was talk about using midibox to control Yamaha soundcard daughter board (DB50XG, probably) a loong time ago.. I don't what happened to that.

You don't need a midibox for this. Just connect the DB50XG to MIDI with a simple circuit:

And here the pinout of the DB50XG connector: http://atari.nvg.org/db50xg/
