    Product Description

    Moog is a household name, among both synth enthusiasts and the wider musician community alike. Famed for paving the way for analog synths, they're widely credited with defining the modern synth formula. For decades, musicians and manufacturers have expanded their setups in pursuit of ever-more complex and unique sounds, resulting in all manner of wild compositions and musical styles.

    In a break from this trend, Moog have stripped away the bells and whistles and produced an intuitive synth that's designed for one thing: play. Say hello to the Grandmother!

    Ready, set, play!

    Looking at its irresistible colour-coordinated interface, it's quite apparent that Moog have built the Grandmother with fun in mind. This setup is designed to encourage experimentation, with heaps of potential patch combinations to play with. You've got the best bits of the classic Moog design; chunky black controls, clear labelling, smooth faders, velocity-sensitive keyboard. These elements have been streamlined to ensure that you'll not only find it easy to make noise with this thing - you'll enjoy it too!

    The only way is modular

    As mentioned before, the colour-coordinated interface makes the Grandmother far easier to navigate. This will be particularly useful for those who aren't experienced in using modular synths - they can often be a daunting prospect.

    Moog have adopted a semi-modular approach. The colourful strips act as modules, despite being part of an all-in-one setup. Inspired by its modular synth ancestry, the Grandmother's sound engine, modulation engine and onboard spring reverb (yep, you read that right) are entirely analog. Add to the mix an intuitive arpeggiator and sequencer and numerous filter options, and you've got a compact synth powerhouse that'll deliver on every level!

    Expansion galore

    A variety of patching options expands the sonic horizon even further. Use this to override internal connections and change the order of the Grandmother's components, potentially resulting in a truly weird and wonderful tonal palette. Finally, the Grandmother can be used as an analog audio processor for external sound sources, as well as a sequencer and keyboard front end for other compatible synths. The possibilities are limitless - go forth and play.

    Brilliant little synth. Incredibly versatile and a sound to die for. I’ve been almost physically attached to it since Day One. Highly recommended if you’re on the fence.
