200e

the harvestman is putting out a module soon called the
"transcontinental rail" I think and it lets you convert modular
signals from the 1v/octave into the buchla so it will track via cv
from euro and frac..etc.

Any idea if Harvestman is going to be dealing with pulse/gate?

Also is everyone happy with the CV tracking on the current revision
Buchla modules? Any voltage droop situations/frustrations?

is this really gonna be made?
i've been waiting ever since i saw the pic on matrixsynth 
a couple years ago
i hope .... :)

One major thing has changed, in that it's now planned to be a Eurorack  
Module. I personally like this, as I'm almost out of space in by  
Buchla cabinet, but it may disappoint some.

Here's a page on it:

I have no idea whether it will ever really see the light of day, but I  
hope so.

I use my system with a Haken Continuum and the Haken Control Voltage  
Convertor, rather than going through MIDI. It takes quite a while to  
tune the voltage control ranges and offsets, but once it's done and  
stored, the tracking feels really accurate to me. I can sweep through  
a complete four-octave glissando (the maximum range of the half-size  
Continuum), and the top note will be perfectly in tune with the  
bottom. Internal intervals in chords sound in tune as well, and even  
when transposing the Continuum by an octave or two, the octaves stay  
in tune. In short, I'm happy with the tracking.

Hello,

Yeah, on the Rails the pulses are properly converted to and from 5V gate signals, 
accounting for dual levels and duration. The general idea of the module is to provide two-
way signal conversion for the three classes of 200e signals: audio, CV, pulses. In the case 
of CV conversion there are also precision attenuators and amplifiers on some of the 
channels for dealing with 1.2v/oct to 1.0 conversion.

I move to Seattle soon where I'm getting my own work's manufacturing in order - giving 
me more time to design. In the case of the Rails a collaboration will be made... while the 
circuits themselves have been done for a long time, some work is needed in panel layout 
and functional quantity selection. 

You'll be able to read about that on yahoo group "harvestman" when that happens. 2008 is 
a great year to do it.

This week I've been doing a lot of work with my 259e, 261e, and DARF, and have generally 
been satisfied with the tracking performance (tested with my ears, not measurement 
instrumentation). However, my Buchla setup is tiny and I'm presently short on bananas so I 
haven't been able to patch up some more intense in-system situations that would put the 
CVs at half-mast.
