Macbeth X-Series Micromac-D

via this auction

"A masterpiece by Scottish synth designer genius Ken Macbeth, this is Ken’s take on the classic Minimoog Model D concept of a 3-VCO synth with a 24db ladder filter.

Ken Macbeth is - besides Wowa Cwejman - the best boutique analog synth builder of our time, doing everything the old-school way of through-hole solering. This is true analog!

The sound that his synths deliver is simply out of this world and the Micromac D is no exception. Despite its desktop size it packs a heavy punch. Seriously - in terms of sound this is as good as it gets.

Here are the specs:
3 x 1v/octave tracking voltage controlled oscillators.

oscillators 1 and 2 featuring 4 waveforms: sawtooth, square, triangle and sine. oscillators 1 and 2 feature pwm control inputs.

oscillator 3 featuring 6 waveforms: sawtooth, square, triangle, sine, ramp and lower frequency noise.

oscillator 2 can be hard synchronized to oscillator 1.

oscillator 3 can be used as a modulation source, both in the audio range and the low frequency range. oscillator 3 can be used to modulate oscillators 1 and 2 as well as the voltage controlled filter. oscillator 3 can be disconnected from the main controlling cv.

oscillators 1,2 and 3 feature separate control voltage inputs for external control sources.

oscillators 1,2 and 3 have separate audio outputs (pre-mixer) for external proccessing in other systems.

oscillators feature separate attenuated volume controls into the filter.

oscillators 1,2 and 3 feature both course and fine tune frequency controls that have a range above and below the audio spectra.

noise generator features white noise with its own attenuated volume control into the filter. setting 6 on the oscillator 3 waveform control allows a lower frequency noise to be used for modulation effects and can also be used as audio source.

1v/octave voltage controlled filter:
24db/octave transistor ladder low pass filter. oscillates at high 'q'/resonance.

tracking of the filter from the main cv input can be 0%/half/full (0v/octave, 1v octave and 1.5v/octave)

the filter also features a separate 1v/octave external cv input for other control sources.

the vcf is swept directly by its own envelope generator.

2 x envelope generators. ads/switchable release type. filter eg can be switch between a positive going envelope or an inverted envelope. filter eg can be switched to sweep oscillator 2 for hard synchronization sweeps. vca eg can be diconnected via an external vca cv input socket.

all analogue circuitry used in the design is the 'old school' through hole parts."
