INTERFACING THE EML 401 MODULE WITH THE EML 101
OR EML 500* KEYBOARD SYNTHESIZERS
EML 101
(Note Diagram 1-1) Connect as indicated. The TUNE rotary control
is used to tune the 401 oscillators and filters in relation to the
101's sources. They may be tuned to unison or to varied intervals.
EML 500
to the oscillator control input of the EML 401 marked - Vext.
Tuning the 401's oscillators to either unison or intervals in respect
to the EML 500's is accomplished with the TUNE control know on the
401
(Note Diagram 1-2) To control the oscillators of the 401 from the
EML 500, simply connect the CONTROL VOLTAGE output of the EML 500
realized by taking a patchcord and connecting the GATE output from
the EML 500 to, the TRIGGER input of the EML 400 Sequencer or of
the EML 401 module.
Initiating the 401's voltage control envelope generator is
In order to have the Filter track the Keyboard control voltage a
patchcord must be connected from the MULT jack to the filter s Vext
jack. Carefully note Diagrams 1-1 and 1-2.
