Hi, This shouldn't be that hard at all. You'll want standard bank mode as there you can define different controllers/events per bank. You can also use leds to show the status and use for example 2 buttons to increment/decrement banks. See about the possibilities by downloading vMIDIbox64E from http://miostools.midibox.org/ which can be used to create a configuration file for the box. Moebius

Why - Oh Why, people want "Keep pushing against the flow"? IF you simply don't know the innards of the thing and there's already a working schematic that spits out nearly the voltages needed for AIN.. *sigh* Moebius P.S. By the way, the schematic shows BC being fed with Negative voltage to power - Yours might already be in Breath Controller Heaven ;D

Your absolutely right! Sorry for that. M

Actually non-regulated PSUs behave like this if not loaded. Yes. Moebius

Heh See http://www.ucapps.de/mios_c.html page :) M

No no! You weren't the first (and probably not the last) person to make this error.. ;D And it was easily solved too.. these things happen especially when you're on hurry. M

Hi, I'm making a wild guess about your power problem: You have put the regulator upside down. Moebius

Hi. Smash ships his kits with polystyrene caps which happen to be the BEST caps for tuned circuits (low tolerance, extremely temp. stabile) BUT Smash also includes caps for both 6581 and 8580, are you absolutely sure You have the right caps for the 8580 in place? Moebius

Ok, I say 'stay with the PICs' :D My only reasoning behind this: Microchip seems a bit more serious about supporting DIP packages than Atmel. Of course the future is SMD, but this is a major problem to some parties. I mean, Atmel gained it's reputation with Advanced 8051 derivates. When I was in the school we were using those - we did prototyping on 3rd party development boards. Whatever each person had as a project was supposed to be possible to "realize" in the real world. Logically (or being brand loyal) the school has moved to using AVRs, but what will the next step be when those are phased out?!? /rant off These seems not to fit for your needs, but still: Former Scenix SX, Ubicom SX is still alive, now in the hands of the Parallax (the basic stamp fame) http://www.parallax.com/sx/chips.asp - PIC 16C5x compatible with speeds up to 75MHz (or even 80MHz overclocked ;)) Moebius

Could this be a power problem? As strange at it seems (with one PIC working and another not). Which MIOS versions? In MIOS V1.8 the "Brown Out Reset" is set to 4.5V (see http://www.ucapps.de/mios_changelog.html) One thing you could try is removing other modules connected to core and see if this stabilizes core operation. M

Or actually if only 8 or less AINs are needed, those can be connected directly to the core. M

Not sure about the innards, but at least the pinout is the same with Yamaha BC2. These are "general" Yamaha breath controllers, probably plugging to many generations of gear from the DX7 to VL series or so. M

Sven - Excellent Work! As stryd_one already suggested this should be in the wiki. Do You mind asking a favour: Could you write a little article to the wiki about compiling on linux with gpasm ect. with your code included. We could use Your expertise here. You can log to http://wiki.midibox.org by using forum login/password combination. Moebius

Hi. Some of these chips are interesting (ATSAM3108 - 8 chan Audio DSP anyone), but the others are rather lame. Making a DIY GM compatible synth isn't really worth it in my book. Even SDIYers are rather using the "raw computing power" of other Atmel chips, than DSP solutions. One reason is that microcontroller chips are usually available in DIY friendly thru-hole packages and these dedicated DSPs are only in some nearly impossible to solder SMD packages. Moebius

Yes - Impressive. And I love to see that people still keep pushing DIY to the directions of their own interests and needs. Building from the scratch. And in the "DIY markets" there definitely was room for acidcode.de 303 clone with sequencer (the sequencer part is still available to be build) and x0x style drum sequencer, even those are JUST "one trick ponies". I'm hoping this diversity will keep people getting interested in Doing it by themselves. Maybe one day we will see some clever ideas even being "stolen" by equipment manufacturers.. I mean, How many times we have to stand commercial products with some simple failures in the design that makes them harder to use. "Average Joe" might happy reading the manual, but I'm not. There are only so many thing You'll actually have to learn, but simple things should be keeped simple and self explanatory. Right? ;) I know You've got some hectic work and stuff Stryd - so I'll keep waiting 'till Your sequencer is ready. I had my ideas of stripped down MBSEQ for drums.. Whoops sorry for the rant.´ ;D M

Hi. I decided to post a notification as I saw Markos announcement on the Introspectiv (Yahoo group) - I have bumped in to this project few times before, but haven't been THAT interested before a working release. He even hasn't borrowed the MB bootloader code (as the acidcode.de did). And no "the Cult of Midibox" talk, please :) All DIY good DIY! MIDIbox COULD do it - but hey, this freaking community has not Written and Released x0x style sequencer for the platform. *grin* Moebius

Hysstt.. Artesia, you shouldn't tell these public secrets before I get couple of these.. well, at least You didn't say it's all over the Aphex Twins Selected Ambient Works... Uh what did I say.. ;D M

IRC: midibox@EFnet, http://www.midibox.org/forum/index.php?topic=5868.msg36138#msg36138 The Forum IS just the place to ask questions.. but not before You have read the www.uCApps.de and the http://Wiki.midibox.org ;) And we at the chan really enjoy our stay (?!) and like to keep it that way.. soo, people are welcome to /join, but please don't mess our precious idling and random babbling with too much midibox context ;D Moebius

Uhhuh.. Sorry - I saw Your post and then forgot to answer - with a link: http://www.midibox.org/forum/index.php?topic=5841.0 Moebius

Yup - there it was :'( hmm.. Twin-x might listen to improvement ideas, so let's see. But DON'T expect anything to happen fast, as he has other things to do also. ;) M

I'm guessing Eagle3D package from http://www.matwei.de/ & POVRay. M

//update Smash did new 3D renders of the core Yesterday.. ;) M
