eml synthesizers

hey all, i'm new around here. about a year ago i got a 101. then over the past month i came
across a 400/401 and a 200. i just brought the 200 home and was trying to interface it with
the 101. i can't seem to figure out why the oscillators won't scale properly. i tuned up the
101 so its playing in tune. then i tried a patch example in the 101 manual. can anyone shed
some light on this? and does anyone have a manual for the 200?

thanks

There's a pdf of the 200 manual in the files section for this group on Yahoo

All I can say about the scaling is maybe when you get the 400/401 home (assuming you
obtained one) you can find out which one has the scaling problem. Or if you are good with
a voltmeter see if your 101 octaves are 1.2 volts apart.

One guess might be that over the decades an unknown number of owners altered their
EML gear to scale with their other 1.0 volts per octave gear. So perhaps someone modified
one of your synths.

The EML200 schematic shows what look like very crude linear (V/Hz) VCOs. AFAIK, the EML101
has exponential (V/Octave) VCOs. Unless your 200 is different from the schematic, I can
see no hope of the two instruments tracking...

yeah, after referencing the schematic and a few phone calls i think
you're right about the V/Hz oscillators on the 200. thats so annoying.
i haven't had time to test my 400 with my 101 yet but i think they
will scale the same. anyone have a schematic for the 400?

I think the original EML 100 was v/hz too. AFAIK, the usual way to
control the 200 was with a 300. I don't know how well the 200 VCOs
would track v/hz - they're utterly primative - so even an expo converter
might not help. The sequencer is probably your best bet.

The 100 was updated to the 101 and the 300 was updated to the 301. Does
anyone know if there was ever a 201?

Only a few random pages which don't all join up, and mainly of the
400 synth section, not the sequencer. I'd be interested to see a full
set of the 400 schematics and also a decent photo where I can read all
the labelling. (I don't have a 400 yet).

What I did find was a page entitled "EML 200 STUDIO SYNTHESISER as the
SOURCE and MODIFIER SECTION for the EML 400 SERIES SEQUENCER". If my
unreliable medieval parallel port scanner can be persuaded to work one
more time, I'll scan it for you...

Note: I am not an EML expert. If any of the above is wrong, someone
please say so.
