Hi everyone, The first "Magic Box" exists and works. I have posted pictures in a new "Magic Box" folder. Keith.

Many of the new members won't automatically realize what's at stake, since they may not have the terminology, the electronics, and the contingencies down yet. Also, the casual traffic that visits periodically from other sites may not have been following the magic box thread. Ed

I like the fact that it sits nicely on top of the module without looking too out of place. What are the sockets on the front though and are they only there due to a lack of space at the back? Chris

Hey Guys,
I took a look to the pictures of the
group, and they're so precious for the DIYer I am :)
Thanx for sharing this !
Then I looked to this 'magic box' in the
gallery, and I really wonder what it is :D
Is it something made to adjust the level of
triggers ?
Are there some amps in it ?
I'm so curious about it ;)
I searched thru the messages but unfortunately,
didn't find any info about it.
Another question : a Roland 3-zones cymbal need 2
inputs on the module. It seems Yamaha found the way to have 3-zones stuff
connected to 1 input only. Do someone know how it works. I thought about
something that could do the trick, using the DC properties of piezo, but I'm not
sure Yamaha stuff work this way.
My idea would be something like that (applied to a
3-zones ride) :
- Piezo + to tip / - to ground &
Switches off = Bow hit
- Piezo - to tip / + to ground
(inverting the signal with a circuit controlled by the mswtich on
the bell) / Bell switch ON / Edge switch OFF = Bell hit
- Piezo + to tip / - to ground & Bell switch
Off / Edge switch ON = Edge hit.
Wiring would then be : Piezo + to Jack tip /
Piezo - to Jack Ground / Edge mswitch to Jack Ground+Ring. Bell mswitch
connected to an internal inverting circuit.
Btw, OldGuyDrummer, your kit is... so BIG :)
Congrats !
Cheers,
PFozz

After I looked attentively to the PCB on your pics,
it seems simpler :)
Each membrane switch is connected to a resistor,
then the resistors to jack's ring (and the remaining 'wire' of the mswitch
connected to ground). Since those resistors are probably different, the
module may independentaly know if mswitches are on or off.
For example :
R=+inf (on ring/ground) : S1 is OFF / S2 is
OFF.
R=50k : S1 is ON / S2 is OFF.
R=100k : S1 is OFF / S2 is ON.
So much simpler and efficient.
Yamaha hits a point with the 3-zones things on 1
input only ;)
But then, Yamaha cymbals shouldn't be compatable
with Roland modules, while the Roland cymbals should be useable with Yamaha
brains...
I'll think twice about it, when I'll be rich enough
to buy another module ;D (I really don't like the internal sounds in Yam's
module, tho)
Cheers,
PFozz
