MacBeth Micromac – lead bass

Background data:

Here’s a short video where I am using both the 3U Eurorack version and the Desktop version of the up and coming MacBeth micromac! This is pretty standard stuff- but this morning I switched the gear on before work and came up with these rather vintage minimoog like sounds! The 3U Eurorack version is on the left side- the Desktop version on the right side!

Short info on the Micromac:

The long-awaited Micromac by MacBeth is a small and yet powerful, full analog standalone desktop synthesizer because unlike his competitors  it has three voltage controlled oscillators and a classic Moog lowpass filter. Never before it was more affordable to purchases a true MacBeth synthesizer!

technical details

The desktop version of the Micromac has not only CV and gate inputs to play the synth but also a MIDI/CV interface from Kenton, who stand for very reliable and stable interfaces.

3VCOs: 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 VCO2. VCO3 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 VCOs1&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 (0%, 1V/oct and 1.5V/oct).

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 be also 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 for manual triggering of the envelopes
