The Grandmother synthesiser brings the legendary Moog modular experience into a semi-modular format that welcomes musicians at every level. This sonic playground draws inspiration from classic Moog modular synthesizers, featuring a completely analog sound engine, modulation system, and onboard spring reverb tank that creates an unrestricted vocabulary of beautiful and powerful sounds. The semi-modular design means no patching is required to start making music, yet the creative possibilities expand infinitely when you begin exploring the patch bay connections.
Beyond its standalone capabilities, Grandmother excels as an analog audio processor for external sound sources and serves as a powerful keyboard front end for expanding Mother-32, DFAM, or Eurorack modular systems. The built-in Arpeggiator and Sequencer add programmable syncopation and enjoyment to your musical explorations, while creative patching unlocks exciting new relationships between modules and reveals the instrument’s true potential.
The magic lies in the journey of discovery and experimentation that Grandmother encourages. Patching can override internal connections, allowing each section to function as an independent module, making this instrument both accessible to beginners and endlessly rewarding for advanced users seeking to push the boundaries of analog synthesis.
