MOTM

Hey, does anyone know what Kind of signal comes out of Yamaha's breath controllers?  Possible 850 compatiblity?  Seems like it should be no problem, but I dont really know if the BC acts like a pedal-pot thingie..

Ordered my 850 and ordered my pedal, Ill have them all rigged up here sitting pretty on my shelf, minus the rest of my modular.. : (
Oh well.  They're like art to me anyway.. Inspiration!

There was a lot of discussion about this subject here and on SDIY recently.
I have a text and schematic I save that Old Crow sent to the list.  I will
forward them to you privately.

Not right out of the box.  It was not designed for that.  However, I have
been contemplating that a very small PCB and the correct size jack for
direct plug in could be added as an after-market mod.  It is on my to-do
list once I get my 850.  Seems like it would be easy enough.  However, what
seems easy doesn't always work out that way.

I have a BC-2 for testing.  I am wondering if the BC-1, 2, and 3 are
interchangeable within the Yamaha DX line where they were so often utilized.

I have both the BC-1 and 3, and both work interchangeably on the DX-7 
(old) and VL-70m(new).

Hi All !

Something weird about these controllers is that they take power 
between gnd and -15v .  Found this schem on the web :

Dunno if the 850 can cope with this .  Mind, i have not tried this 
out, inversion and/or level shift might be needed to be of use in an 
MOTM environment .

Btw, i missed a bunch o mails from the list when stupid y*h** 
unsubbed me .  Took me a while to wade through that mudpatch of a 
website to learn my email address was nonexistant .  Yeah right . 
Moreover my trusty browser hickups when trying to read the mails .  
And to add insult to injury, i can't seem to find a way to send 
myself the missing messages .  Anyone knows if this is possible at 
all ?  Alternatively, would anyone of you be so kind to send these to 
me .  Best to keep this to private mail .

Thanks a bunch .


Keep 'em oscillating :)

If you search through the past few months of posts in the archives I posted 
what I measured the voltages to be.  Negative voltages are there, and none of 
the tip/ring/sleeve had ground on it.  It isn't what it seems like it should 
be.  Nobody else seems to be able to confirm or deny what I measured so 
apparently nobody has ever built anything for it.
