Evolving on the classic analog concept of the Mutuca synth, the Mutuca FM adds an oscillator and expands the modulation palette with FM and Sync.
I was quite happy with the Mutuca as it was; a lovingly crafted little single oscillator analog synthesizer. However, introducing another VCO with a bit of FM and Sync between the oscillators really does expand the possibilities and takes it to another level. Mutuca FM is a peach of synthesizer.
As with the Mutuca, you get this gorgeous vintage styled, compact analog synthesizer designed and built by Arthur Joly in Brazil. This time it has two 3340 based VCOs with independent controls and waveform options. With the flick of a switch you can add in a sawtooth, triangle or pulse width modulated square wave to the signal path. This then routes through the 24dB/Oct matched transistor VCF and out via a VCA and a bouncy VU meter. An ADSR envelope provides modulation and (I think) the switch spins it into a loop.
The fun thing about the Mutuca FM is that VCO2 can also act as a modulator for both VCO1 and the filter. A modulation knob dials in as much of VCO2 or the envelope as you want. With a switch, you can pitch VCO2 down to be an LFO if you prefer. If you want to keep both oscillators as sound then a Sync switch keeps the VCOs together or you can let them flow into detunable loveliness.
Another interesting addition is the Key/MIDI switch on each oscillator. This lets you decide whether to play the oscillator from the awesome looking 2-octave button keyboard or from a MIDI controller and being able to split these off independently is very cool.
There’s no patching or anything, this is a straightforward analog synthesizer that would look good and sound fantastic in your studio or on your coffee table – those colours are just so right. The price is BRL 4,600 (Brazilian Real) which equates to about £630 plus shipping and tax and it takes about 90 days. It ships in a hard flight case which is making international orders a bit more feasible. Well done, Arthur Joly.
