Re: EML-101 and Kenton Pro-2000

2008-06-26 by nicholas_kent

There are really 2 more or less separate things to deal with. 

First, obviously to plug it in, the 101 seems to have had a number of changes during it's 
lifespan. On mine I found 1/4" jacks at the top for SEQ IN and one of the EGs in. Even if 
you don't have the scaling worked out yet you can see i you can trigger and what you can 
change the pitch to. I need to revisit trying to connect mine, but my initial solution for my 
101 was to unscrew the keyboard connector enough to attach alligator clips to the pins. I 
figured out which pin did what by using a voltmeter and playing the keyboard.

I had 2 different Kenton MIDI to CV converters at the time, though not the 2000. They did 
not scale to the full 120% of 1v/oct needed to achieve 1.2v/oct.. In my mind the best 
known and most favored solution is to take a mixer module made by someone else,  
attach a Y cable to the kenton or use a multiple and send the Kenton voltage to 2 DC 
voltage compatible mixer channels. You'd turn the first channel all the way open - so that 
means 100% comes out of the mixer as typical mixer modules never amplify. Then start at 
around 20% on the second channel and adjust it until it scales. I was using a Doepfer A-
138a module. It needs to be powered and go in a rack, but the module itself cost me 
under $20 used. Current U.S. retail is $80.

When using the keyboard connector I found that the gate signal causes the 101 to hold 
the voltage. It probably has to do with the duophony, which seems to be controlled by an 
offset voltage so if you only play 1 note both duophonic channels track the same thing? 
Anyway the upshot is I started adjusting the scale and didn't hear anything then I'd play a 
key again and get something completely different, because I was expecting to hear the 
change in the voltage I was manually making "live". Anyway once I figured out I had to 
keep hitting a key to hear a change I got the hang of it. 

Another suggestion is just to scale for an octave or 2 on the keyboard playing an octave of 
pitch and at first don't worry that your C isn't playing a C just as long as a the pitch from 
one octave to the next really is an octave. Once it is it's easy to make the C into a C with 
the vco tuning on the synth. 

Anyway I did get the 101 to play  correctly pitched from MIDI with all the VCOs and EGs 
going. For what it's worth I didn't attempt to control the duophony.
