Moog Liberation

The Moog Liberation is the first analog synthesizer worn around the neck ( Keytar ) produced in series. The prototype was unveiled at NAMM in Anaheim in January 1980 and was in the same year in series production until about 1984.

It consists firstly of a monophonic synthesizer part and on the other from a polyphonic part, which could only produce a rectangular waveform. The keyboard has 44 keys from F to C, it has a kind of aftertouch, in which a mounted under the keyboard sprung rail can be additionally pressed after the actual hitting of the key down so as to serve as a further " Modulation ". The " guitar neck " next to it contains the actual classic game aids such as modulation wheels and pitch bender.

Construction

Oscillators

Of those 2 with the waveforms sawtooth, triangle (with two OSCs ) and pulse wave ( pulse width 10%) at OSC1 or OSC2 rectangle in. The pitch can at OSC1 to 32 ', 16 ' and 8 ' at OSC2 16 ', 8 'and 4' set. Oszillatorsyncronisation is also provided, including OSC2 can be fine- tune against OSC1 (a little more than the fifth).

Filter

Only one type of filter, namely the 24dB - Moog octave low-pass filter, with the controller options "Cutoff ", " Emphasis" (resonance) and " filter amount". Keyboard tracking is also in the 3 steps "off ", " ½ " and "1 " is possible.

Envelopes

Of those 2, of which a filter envelope and volume envelope both with "Attack ", " Decay / Release " and " sustain " controllers where the release for both curves can be hooked up separately and then takes on the value of the decays.

Mixer

Here not only the two oscillators and the polyphony, but also the pink noise and ring modulation can be mixed.

Modulation

1 LFO with the waveforms triangle, square and Sample Hold. The speed ranges from 0.3 to 30 Hz, it can on the filter and the pitch of the OSC1 and 2 (but not to the Polysektion ) are applied. The LFO can also trigger the envelope.

Game aids in the " guitar neck "

  • "Pitch Ribbon Controller " with a range of more than 5 semitones in both directions
  • "Volume - wheel" for volume control
  • " Filter wheel" this is spring loaded (allows the wheel after the release for zeroing back fast ) and has as a function logically, the opening and closing of the filter
  • " Mod wheel " to control the amount of modulation by the LFO
  • " Glide On / Off switch to" on and off the Glidefunktion whose duration is also adjustable
  • " Force Wheel " for controlling the modulation intensity by aftertouch
  • " Bend / Mod switch" to select the function of the aftertouch

Aftertouch

This can be used both as a " modulation " of the LFO ( mod ) or as a pressure responsive intensity modulation, to say the stronger the pressure, the stronger the effect modulated ( Bend ). It can be influenced Pitch, Filter and the hard-sync using the aftertouch.

Polyphony

The Polyphonic section of Liberation is achieved using the frequency division technique. It is this, however, only a single wave form, square wave. It is mixed in a blender and then passes through only the filter and envelopes. It is not modulated with the pitch bend, but, however, the number of votes is unlimited.

Special

  • The Liberation basically consists of two parts, the instrument itself and the "Power Supply Interface", both connected by a 12 m long 6-pin XLR cable. In the interface, the power supply and the external control outputs are housed.
  • The Liberation could also be ordered in black, red or white, and there were the option whether you wanted him to pitch ribbon controller or pitch wheel (Tom Coster preferred, for example, the wheel ).
  • After switching on the Liberation takes about 10 minutes to the oscillators to the right temperature and therefore are brought in tune.
  • One of the few Moog with ring modulation, from small only had the Concert Mate - MG1 a ring modulator.
