Fair point, but isn't it worth finding out more about this chipset first?
To see if it can actually be of use as a future core for the MIDIbox platform?
And at a later point in the future a decision can be made.
-
After reading the specs it seems that this could be the brain of a future MBHP_CORE_xxx module :)
Would it be worth introducing the MIDIbox platform in this subforum?
http://www.raspberrypi.org/forum?mingleforumaction=viewforum&f=4.0
Especially since the aim of the Raspberry Pi is to get young people into programming,
very cheaply.
A thread introducing an Open Source project like MIDIbox would be a breath of fresh air,
as most posts on their forum are about using the device as an everyday PC, so they could do with more programmers posting there.
If collaboration is viable, then it may enable us to get information about the chipset faster,
as well as general info.
I think the MIDIbox project would gather a positive response,
as music is a very attractive and good outlet for young people.

i wonder why you brought tis thread up anyways, yours was working nicely and is documented on yt (midibox sid v2 basic drum demo?)
or did you fill ´er up with murphys draught accidentially ? :)
Hehe, the murphy's would probably have done it some good!
There was a few leds not lighting when I made that video and the cabling detoriated over time.
I went and soldered the cables to the pins on the Baseboard like you done in the end.
The Base Board connectors fit in okay, but the crimps qwew a bit loose inside them, so the contact wasn't great,
and certain things went unpowered.
The connectors and crimps I used were the low profile version (brown) of the 3 Pin ones used for Chasis Fans in PC's,
or even the Power LED in the Commodore 64 (the holes are quite big).
So I would recommend using Smash TV's style crimps and connectors (the same type that is used for HDD Leds, Power LEDs, and Reset Switch in a PC)
as they provide a better contact.
I may have to change the connectors on the CS PCB to these down the line, but so far It seems to be okay.

haha. i've literally been following smithy's build for years. glad you got it finished you tardy bastard :)
Get Oot of my thread you smelly inbred degenerative knacker!
This board aint big enough for 2 Irishmen!

Well after soldering 66 wires yet again....
and after threatening to sell it for parts if it didn't work this time....
What happened?
It worked!
Its finally done and luckily the Earth hasn't imploded on itself...
which means there will be time to play with it. :)
There are 2 optional extras I must do down the line, like the LCD window and the feedback pots,
but I think I'll have a bit of fun using it vanilla, before then!

After reading the specs it seems that this could be the brain of a future MBHP_CORE_xxx module :)
Adapting MIOS32 to this platform won't be so much effort, and there are enough IOs available to connect commonly used hardware extensions (DIN/DOUT/LCDs/AIN via SPI/AOUTs - even MIDI could be made available via the "debug console" UART)
Accordingly a migration of MBSEQ V4 is feasible.
Graphical extensions will be available for free, e.g. to visualize sequences on a huge TV screen in HD resolution (I already see Hawkeyes smiling face ;-))
In addition it seems that it has some nice interfaces for Audio, and an integrated DSP.
Best Regards, Thorsten.
I fapped. :sweat:
Imagine the possibilities!
My dream sequencer could easily become a reality.
Something like MB SEQ V4 Lite, but with 16+ real time looping channels,
with the ability to edit data on screen,
and also playback of WAV Samples i.e. a drum machine or sampler.
If the hardware proves to be the next logical step for midibox this could be a very exciting development indeed.
-
Thanks for sharing such an awesome little device!
Just think of the possibilities!
The cheapest 1080p media player/centre known to man.
This will make my WDTV look like an overpriced piece of junk.
There's just so many cool things you can do with this little guy. :)

There was this....

Click this link to skip to the recording of the notation from a Synthesizer:
#t=5m55sJust another example how the people of Xerox PARC were the true innovators of modern day computing.

Also, how can that website get away with shamelessly stealing the YAMAHA DX logo?
LOL! I have never noticed that before, and I've bought quite a lot of stuff from the site!

Und ze Crazy Irischman makes a triple post:
If you built a single Midibox SID first, then an MB-6582 like me* you could possibly create the signal path below,
as you would have 9 Band Pass Filters:
So the signal path would look like this:
SID1 SAWTOOTH__->_____SID2____->____SID3
______With BP_______A.In + BP_____A.In + BP
SID4 SAWTOOTH__->_____SID5____->____SID6
______With BP_______A.In + BP_____A.In + BP
SID7 SAWTOOTH__->_____SID8____->____SID9
______With BP_______A.In + BP_____A.In + BP
A.In = Audio Input
BP = Band Pass Filter.
SID9 = Your single MB-Sid
* When i say built, i don't mean 100% finished. ;)
-
Using the filters in parallel would achieve better results actually.
So lets say we played the exact same preset on all 8 SIDs,
but with a different Cutoff frequency for each of the 8 Filters set to Band Pass.
Would this have the same effect as using filters in Parallel?
Obviously without having the audio output of each sid going to each input in the next, this time round.
-
SAM used the good oul PCM trick by shifting the Volume Register on the SID rapidly,
so none of the actual oscillators are used.
Somebody needs to try Formant Synthesis with the MB-6582.
Have each SID Audio output connected to the Audio Input of the SID next to it, and use Band Pass filtering on each SID.
something like this:
Flemming was explaining the band pass approach to me one day in the chat,
and I thought it would be cool if someone tried it with a bunch of SIDs.
-
Been there, done that...
It seems that the relevant BB code extension is not installed for this forum.
Yep, maybe the embedded vimeo vids on midibox.org/blog gave you the impression that it was done on the forum before.
-
Well, the topic title says it all...
does not seem to work...
Thanks!

An 8-bit Atmega based synthesizer in an organ shell.
Over 1-million views in 10 days, i didnt think such a video could generate that many views! :blink:
Edit 2: The video is actually a year old, i mebbé haz teh dislechsia.
Edit: I guess its down to how well its presented and how well he has played the tracks,and made them sound so close to the originals.
-
Smithy, your drums are great - thanks for upping!
Made a very little live track with them, also featuring the Yamaha FS1R FM synth :)
Greetz,
Hawkeye
haha,you're probably giving me too much praise for the drums but glad you enjoyed them!
Another nice track!
Parts of your style reminds me of Ulrich Schnauss at times. :)
-
Excellent track Hawkeye, really love those beautiful arps, haunting.
-
A cheaper starter project would be to buy a Core Module Kit and Sid Module Kit from Smash TV along with the MB-6582 Kit.
Thats how I started, the wiring would take a little figuring out, but read as much as you can beforehand and you'll be fine!
With Hawkeye's extra detailed documentation, the MB-6582 is a lot more straightforward.
All you need really is experience in making the perfect solder joints, and once you have that, the world is your oyster!
-
but isn't it weird that it only does that when it receives midi clock on top of signal?
The power supply is an universal one... set to 12v, 1a
Its strange alright.
1A should surely be more than enough for your MIDIbox, you shouldn't have had to reduce the lcd brightness.
Maybe theres a short near the tracks from the midi in / optocoupler?
Does it only happen with the midi clock, or does it happen when you send MIDI CC events to it also?
Another possibility is interfernece from the clock signal.
Im stumped. :unsure:

Is the high pitched sound,the improvised hihat your hear in his tracks Tonka?
Have you ever tried using the SID DUMP tool to see what parameters are being used in his tracks?
If you haven't seen it before, its in the Wavetable tutorial in the manual.
IT should help figure out the exact parameters of each sound.
This is something i've wanted to get around too thats been long overdue.
And Speaking of Matt Gray & Rob Hubbarb,
Gray's remix of Crazy Comets has some cool funky sounds too!
-
It sounds like you either have a short, or that your power supply is not providing enough current.
What PSU are you using?
I would double check each joint for shorts if i were you, to be certain.
-
Briefly messed with Rutgers drum editor for the first time, and i love how the sequences update in real time!
I guess its to be expected since all controls update in realtime, but it just feels so great.
-
Heres the few patches i made with my limited time with the mb-6582,
thanks to Hawkeye for the inspiration and motivation that helped me to pull this baby out again, in order to commence re-wiring.
Fairly basic and raw, tweak them to your preference.
It includes the patch i made for my basic drum demo...
I had it saved as 2 patches, they may be identical as i dont have the CS hooked up to find out.

Unlimited POWAH!
The concern I had was if the A8 had sufficient I/O pins to interact with the MB modules,
since I have no idea how a "hobbyist" or "simpler" processor like the Microchip PICs etc...
would compare to a more powerful processor like the A8 which I guess has a far more advanced architecture.
Will the A8 require more components to interact with the modules?
Or does it have similar I/O pins to ze current uC's we use?
Edit:
Realizing that the LPC17 is also an ARM processor, I see that the Broadcom chip would need to be sold in a similar manner,
i.e. on a 3rd party PCB that allows for decent I/O interactivity.
Still have no Idea if the Raspberry PI PCB would be sufficient enough though! ;
Probably not I'd guess!
