PANEL JACKS EML 101(Listed from left to right)(Arrows down inputs;arrows up outputs)KEYBOARDVOLTS (output)-Constant voltage source;stereo output,+10 V,-10 V,nominal.Glide (input)Used with optional 101 foot switch for turning glide on andoff.Gate (output)A voltage source of approximately 15 volts which is "turnedon"for every key depression.When a key is depressed,theGATE VOLTAGE immediately goes to +15 V and will remain atthat level for as long as the key is "down".The GATE may be used to initiate envelopes of the 101,"step"a Sampler,initiate external add-on control functions(Envelope,Sampler,Sequencer)of the EML 200,EML 401 module,and EML 400 Series Sequencer.CM 2 (output)Keyboard 1 control voltageLowest key 4.4 volts (+10%)Highest key -8.8 volts (+10%)Theu the0.5v-6v.xnnSequencer (input)-EML 400 Series Sequencer quantized,exponential,or linearvoltage input for pitch control of Oscillators 3 and 4.Oscillator 3 must be in the KB2 mode,Oscillator 4 in CM3 mode.OSCILLATOR CONTROL MIXERExternal (input)-Used to introduce external control voltage sources into theoscillator control mixer.Patching an external control sourceinto EXT,negates the presence of Oscillator 4 in this mixer.Oscillator 4 being replaced by the new control source.Turningthe lower "pot"counterclockwise determines "how much"of thenew control source signal will be in the mixer.OutputThe mix of control voltages is outputted at this jack.If the"pots"in the MIXER block are both set to zero nothing will beoutputted.(i.e.If the uppermost "pot"is set to 9 o'clockand the lower "pot"set to 2 o'clock,the proportional mix ofthe control voltages from Oscillator 1 and Sampler will bepresent at the output.
