This is the second video aimed to demonstrate the diverse capabilities of the three oscillator desktop sized MacBeth X-Series Micromac-D analogue synthesizer. In this video, we get to hear what the Oscillator section does, plus a few extras! As always, when things get going- hows does one adequately show what the potential of this thing has? Watch on………..there’s some Trio-phony too!
This is the first video aimed to demonstrate the diverse capabilities of the three oscillator desktop sized MacBeth X-Series Micromac-D analogue synthesizer. In this video, I briefly explain the functionality of the unit.
Nice black and white studio capture featuring to classic machines, details below:
Here is (1 of 2) videos that I’ve made demostrating the MacBeth Mk1 Modular and two Korg Prophecy Synthesizers. The Mk1 Modular has 5 Oscillators and 2 Sub Octaves going into a Mk1 Low Pass Filter ‘A’…the Prophecies provide ambient sounds and Tenor Saxaphone sounds. The Tenor Sax is a reeds algorythm model………it all makes for a very interesting mix. I’ve tried to reproduce the kind of sound from the Bowie/Berlin seventies days! This is the first video…
The Micromac-D by Ken MacBeth is a small and powerful, full analog standalone desktop synthesizer such as the eurorack module Micromac-R now including the Kenton MIDI-Interface and some extra features. Unlike his competitors it has three voltage controlled oscillators and a classic Moog lowpass filter, as a tiny desktop synth it could become indeed the bonsai-version of the M5 as the true MacBeth synthesizer!
The desktop version of the Micromac has not just CV and gate inputs to play the synth, but also a MIDI/CV interface from Kenton, who stand for very reliable and stable interfaces… and a few news with the additional LFOs.
3 VCOs: VCO1 and 2 have saw, pulse, triangle and sine waveforms and the pulse width can be voltage controlled by external CVs. A low frequency noise with level control is available as well. VCO 1 can hard sync VCO 2. VCO 3 can be used as a modulation oscillator and can be disconnected from the master CV. Modulation targets are filter cutoff frequency and/or pitch of VCOs 1 and 2. All VCOs have individual outputs, coarse and fine frequency controls, separate CV inputs for controlling frequency and pre-filter level controls.
The filter is a Moog 24dB lowpass filter. It´s input is a mixture of all three VCOs and noise. The cutoff frequency can be controlled by the first envelope generator as well as by an external CV. The filtertracking is switchable between off / half / full.
The envelopes are ADSRs with a switchable release parameter thats time is depending on the decay parameter, just like the Minimoog. The filter envelope can also be used to control VCO2´s pitch what sounds great when VCO2 is synchronised. Furthermore you can invert this envelope´s characteristic. The second envelope modulates the VCA. If an external CV is patched to the VCA the internal modulation is broken up. A momentary button allows manual triggering of the envelopes.
Seen here- Prototypes of MacBeth NEXUS and INFERNO synthesizers.
“On the left I am playing a 1 Octave final test Touch Keyboard Assembly. I have this setup to check everything! The repetative rhythmic sounds are coming from the INFERNO prototype- the more lead/wash is coming from the NEXUS!”
Kenton Retrofit kit adds MIDI to the MacBeth M5N synthesiser
Ken MacBeth tests out the prototype of his upcoming MacBeth Studio Systems Nexus touchpad synthesizer, details below:
As I finalize the design of the NEXUS synthesizer for production- I took it the prototype through to the work bench. Basically- the work/refinements are complete. This recording has no external effects- the only sounds are from the NEXUS itself! I’ve designed a synthesizer that has the type of sound, similar to that used on the David Bowie trilogy that was recorded in Berlin in the seventies- see what you think!
Well after 5 teaser videos from MacBeth on the Nexus it sure seems like the new synth is coming together nicely
“When I’m testing gear that I’m designing- it’s quite exciting!….sometime I have to record/vid. Here is three of the NEXUS (prototype) being driven by a Korg SQ-10 sequencer- the fourth osc is cross modding the higher pitched square wave osc. It’s great fun running a three track analogue sequencer into this thing! Spacey effects are as usual with this device- the Dual Tape Delay Simulators- no other effects! Today- on screen- I basically finished the synthesizer. I’m looking forward to submitting the data to manufacture next week…! This btw is basically two different experiments filmed at different times…”
People have asked that MacBeth do a video of the NEXUS prototype again- more features now added include Octave Switch for all 4 Oscillators. For Oscillators 1 and 3- seperate Pulse Width Modulators have been added- separate mening independant of each other and of the on board LFO. Fatten your sound up with a full on 4 Oscillators! Also featured on this synthesizer are a Dual State Variable Filter, 4 Envelope Generators, Dual Noise Generators, Dual VCAs and Dual Tape Delay Simulator circuits! NEXUS is a true stereo analogue synthesizer with touch plate keyboard! In the hands of a real musician- this thing will work wonders!
To give you a flavour of the 5 Oscillator/ 2 filter sound- MacBeth set up this on the M5X prototype. It’s pretty massive with hints of spring line reverb and cross modulation from one of the VC Modulators modulating as well as being audio! It’s a booming, massive sound!
