Macbeth Elements 2017

This is one of the final MacBeth Elements synthesizers bought directly from Ken MacBeth in the summer of 2017. Comes with custom MacBeth dedicated power supply. This is far and away the best sounding synthesizer I’ve ever laid hands on, it sounds absolutely huge. The Elements is capable of a wide range of sounds, further expanded by using and abusing the onboard tape delay simulator and spring reverb. The synth has never left my smoke free home and is in the exact condition that it received it from Ken. There is one small surface flaw on the left side of the touch keyboard that the unit arrived with. When purchasing from Ken his contract mentions the possibility of small aesthetic flaws that do not have an effect on the performance of the instrument. I’ve tried to capture this in the photo. Ken has ceased production on the Elements synthesizer, this is one of the last handful produced. Will ship fully insured. Feel free to contact me with any questions
Here are technical specs:
macbeth elements synthesizer specification:
self contained synthesizer with built in touch capacitive keyboard

3 wide ranging voltage controlled oscillators and 1 vc low frequency oscillator/audio oscillator.

vco1: 5 waveforms: ramp, square, enhance, triangle, sine.
multi turn vernier dial tuning frequency: 1 hz ~ 20khz and beyond.
volume output direct to vcf.

vco2: 5 waveforms: ramp, square, enhance, triangle, sine.
multi turn vernier dial tuning frequency: 1 hz ~ 20khz and beyond.
volume output direct to vcf.

shared enhance rate between vco1 and vco2, variable from slow ~ fast.

vco3: 6 waveforms: ramp, square,triangle, sine, saw, s&h
multi turn vernier dial tuning frequency: 0.01 hz ~ 20khz and beyond. transpose switch: lo, -2, -1, 0, +1, +2.
cv on/off switch.
vco3 hard synchronization to vco2.
volume output direct to vcf or cross modulate vco2.

temperature compensated vc low frequency oscillator/oscillator (vco4): 6 waveforms: ramp, square,triangle, sine, saw, s&h. frequency rate variable from slow ~ fast- approx: 0.01 hz ~ 20khz and beyond. cv on/off switch. fast ~ slow switch. s&h selector switch: noise source or vco3 source. mod vco3 potentiometer, mod vcf potentiometer, audio to vcf potentiometer, large global modulation potentiometer.

noise generator: white noise, pink noise. volume output direct to vcf and s&h circuits.

external audio input amplifier: volume output to vcf or ring modulator.

ring modulator: mc1469 based double balanced modulator. inputs: vco1 sine, vco2 sine or external audio input amplifier. volume output direct to vcf.

voltage controlled filter/ resonator (vcf): self oscillating, 5 'rung' diode ladder type approximating 32db/octave roll off slope. self correcting volume gain at high 'q' (response). cv/keyboard tracking switch: off (centre) half, full. vco3 modulation potentiometer, vcf eg sweep potentiometer. pure sine output at maximum resonance/response. targeted to ca3080 based voltage controlled amplifier (vca)

vcf envelope generator: full attack, decay, sustain, release with long ~ short timing switch. vcf eg polarity switch: positive or negative going slopes. vcf eg > vco3 sweep switch.

vca envelope generator: full attack, decay, sustain, release with long ~ short timing switch.

tape delay simulator: input direct from vca. delay time potentiometer, delay modulation potentiometer, delay modulation control switch: vc lfo ~ kbd cv, delay repeats potentiometer, delay mix potentiometer. final output to spring reverberator circuit.
spring reverberator: external spring line tank connect via �" jack socket, standard tank supplied: compact belton/accutronics bmn3bb2c1 for wall/under desk mounting. other tanks/accesorries can be used.

keyboard: touch capacitive gold plated articulator allows 4 octave f ~ f chromatic span.
control source via switch can be touch keyboard, midi or external cv/gate. keyboard can send 1v/octave and +12v gate signals from outputs on the rear of the unit to suitable ancillary equipment, ie, external vc synthesizer/vc synthesizer modules.

other controls: ultrabender: dynamic pitch bend + - 2 octaves either side with dead band in the centre of play. master tune- + - octave either side. global portamento- applies to all cv controls.

rear section interface: midi in/thru, cv in, gate in, vco1 cv in, vco2 cv in, vco 3 cv in, vcf cv in, external audio in, cv out, gate out, synth out, power in.

dimensions: 19.2" width, 15.1" depth, 2.0" height. with detachable rubber feet: 2.15" height.
