GR-1 Granular Synthesizer

Tasty Chips Electronics is raising funds for GR-1 Granular Synthesizer on Kickstarter! The GR-1 Granular Synthesizer is a hardware musical instrument, offering hands-on controls to create characteristic textures and pads.

We brought you initial news of this last month and now the Kickstarter campaign for the Tasty Chips GR-1 hardware granular synthesizer has started. Here's the details direct from the page...

The GR-1 is a hardware polyphonic granular synthesizer in a class of its own. The GR-1 is capable of creating textures, characteristic sounds, drones, soundscapes, pads etc. with the help of your creativity! A sample and a few knob tweaks is enough to create something beautiful!

The GR-1 is massively polyphonic: 128 grains per voice, times 16 voices = 2048 grains in parallel. It employs 32 bit mixing and a HIFI stereo DAC for rendition. A 7" full colour display that is typically only found in top class synthesizers. It can use (USB or DIN) MIDI keyboards, USB sticks/disks, USB audio interfaces, and even PC keyboards. Yet it also features CV interfaces for integration with Modular (Eurorack) systems.

The on-board controls and MIDI connectivity make it extremely easy to manipulate sound. Directness is nr. 1 in the design: knobs and sliders allow all granular parameters to be changed in seconds. The GR-1 also allows stand-alone operation: No MIDI keyboard required! The GR-1 has buttons and sliders to create 4 note chords or drones. (see video demo, stand-alone "play" mode) Use the built-in headphone amp to create sounds fully standalone. It's modest form factor of 32 x 21 cm and light weight allow it to be taken everywhere in a small backpack.
