Proper integration of 38A ADSR Expander

Proper integration of 38A ADSR Expander

2008-10-21 by (i think you can figure that out)

All,

For some reason my ISP (bless their heart) has changed my password and
I can't get to them to find out what the f it currently is.  Sounds
like a pile, please note my hosting is run by an old friend of mine, actually the guitar player in a high school band is was in named Sanpaku (I plyed flute and sax if you're curious). It's a
small semi-private network and the guy sometimes goes dark for weeks
at a time while he's working on his own projects.  In any event I
can't upload to our site until I get the magic number and I wanted to
give an outine here in the meantime on how the 38A needs to be connected.

There are a series of four jumpers on the Model 38 ADSR.  One each for
ATTACK, DECAY, SUSTAIN AND RELEASE. These jumpers look exactly like
the ones used on the SCSI drives of olden days.  You will notice each
jumper can be shorted to the center section and to either the W/ 38A
and W/O 38A position on their far end.  To use the 38A, the jumper for
ATTACK DECAY and RELEASE must be moved to the W/38A position, while
the SUSTAIN jumper remains how it was when the 38 shipped, in the W/O
38A position.

As soon as I can I will upload a photo which shows how the cable is
connected.  

thanks for your patience on this, and if you happen to runi into Mario
Salinas (my ISP), tell him I need to speak to him!

thanks,

- P

Peter, are the jumpers for shortening the ADR times in the Elf 
Envelope? I'm not exactly sure what you are saying about the jumpers. 
I did want to shorten the ADR times of the Elf Envelope because the 
knobs are waaay too sesnsitive even after having adjusted the trimpot. 
Are you still working on the fix for this?

Yes.  there is a block of four jumpers on the corner of the ADSR
board. They come with the module. Each is labeled to whatit controls
A, D, S or R.  With three rows of four functions, each jumper can be
placed to short the top two or bottom two positions of any given row.

hope this helps.

I'm looking at the Model 38 ADSR jumpers and they aren't labeled. I 
don't see any "ADSR" to indicate which jumper is which. I do see "NO 
38A" at the top and "WITH 38A" at the bottom of the jumpers. With the 
knobs facing me, going from left to right, are the jumpers RSDA? or 
ADSR?
