GR-Mega Granular Workstation (Black) – Preorder


The GR-MEGA is a granular hardware synthesizer, sampler, effect, sequencer, and spectral time stretcher. It is a sound design powerhouse, our top model, and the culmination of the journey we started 7 years ago with the GR-1: the world’s first real granular hardware synth.

This is a preorder with a down payment 1/3 of the total price (total price = 1500 ex VAT). First units will most likely be shipped early February.


The GR-MEGA is a sound designer’s dream, offering near limitless possibilities to record and manipulate samples, even in real-time, all supported by a hands-on interface that gives you instant access to complex modulation, slicing and dicing, sequencing and effects.

The GR-MEGA is a sample-based device. Record audio with the built-in high quality inputs, and you are now ready to granulate all your source samples into countless variations. Anything is possible, ranging from subtle changes that still represent the original sample to a completely mangled and scattered manipulation of the original. Imagine what it would sound like if you hear thousands of little sound particles (grains) swarming around to reconstruct any sample you present it. Depending on what source sample you want to use, results can be lovely, soft, and soothing but also chaotic, aggressive and unpredictable and everything in between.

The GR-MEGA is 4 layer multitimbral, and massively polyphonic, and has a wide choice of engines ranging from a traditional sampler with slicing, to a spectral phase vocoder, and of course granular. It’s capable of 128 grains per voice, which can add up to a total of 5000 grains simultaneously. Playing rich chords to create granular harmonic clouds is an easy task. Hook up your (USB or DIN) MIDI keyboards and you are ready to go.. Or just use the on-board chord sequencer.

The GR-MEGA offers hands-on high quality controls for nearly everything it offers, a dimmable 7″ scratch proof display, and a wide range of interfacing possibilities like high quality audio inputs, the ability to be used as a USB sound card by PC/Mac, and easy access to USB sticks and drives.
