Glou Glou Announces Moutarde, 4-Voice PLL Hardware Synthesizer

This unique desktop synth uses Phase Locked Loop Synthesis to generate some weird and wonderful sounds, and it has a whole bunch of tricks up its sleeve. See and hear it in action here.  

New from developers Glou Glou is MOUTARDE, a gorgeous-looking and great-sounding PLL (phase locked loop) hardware synthesizer that's capable of some neat tricks. Check it out in action in the videos below, and read on for pricing and other details.

PLL (Phase Locked Loop) is a technology allowing the control of a VCO (Voltage Controlled Oscillator) by an audio source. The PLL will only work properly when playing single notes, avoid playing chords unless you want to hear sonic


At the heart of MOUTARDE there are 4 low-pass filters running in parallel. Each filter can be controlled independently. Cutoff (FREQ), resonance (PEAK) and modulation depth (MOD). You can feed the filters in 3 ways: dry signal, gated fuzz or PLL. PLL consists of 4  audio-controlled square wave oscillators. Octaves, fifths, simple or complex chords can be obtained by tweaking 2 rotary swicthes. (VOICINGS) , (TRANSPOSE)

Filters can be blended with the dry signal. (MIX) Modulation applied to filters frequency can be either envelope, LFO or expression pedal. (MOD) The LFO speed can be controlled by envelope or expression pedal. (LFO CTRL).

Price: 520 Eur
