grainfields

8 voice granular synthesizer for monome 128 grids

grainfields turns your monome 128 grid into a granular synthesizer with 8 voices - each with up to 10 constant streaming grains. Modulate grain parameters (pitch, duration, loop rate, position etc.) of each voice to create a large variety of interesting timbres and textures. Record and loop pattern gestures to create rythmic and melodic sequences.

Grid overview


Feature overview


Getting started

Before launching grainfields make sure that your grid is connected. At the lower right corner of the app go to 'audio & osc setup' and choose your device in the serialosc dropdown (should auto detect).

Set your audio settings and enable audio.

8 rows / 8 voices

Every row represents a voice, and each voice contains a buffer with up to 10 individual grains. To change buffer content simply drag and drop an audio file into the waveform display of a voice.

Grid controls

• Each voice is activated by pressing the far left toggle on the grid.
• The pattern recorder is activated when pressing the second toggle from the left.
• Step 3-15 on each row control the playback position the buffer audio content.
• The far right toggle records an input into the buffer of the selected voice (change input source in the 'audio & osc setup' menu in the app).

Grain parameters

Control the grain density, base pitch and deviation, duration, loop rate, amplitude, envelope slope, and stereo spread of each voice. Additional parameters include:
• 'speed' - sets the speed of moving between grain positions in miliseconds.
• 'fade' - sets the fade in / out time when activating / deactivating a voice.
• 'rec length' - sets the length of recording into the buffer.

Global transport & pattern recorder

Start / stop transport by pressing the space bar. The transport needs to be activated in order to record pattern gestures.

Set the desired length of the pattern loop in bars (default=2).

Recording into buffer

When recording an input source into a buffer the buffer will autosave the recording into the project folder (located inside the "media" folder).

Master presets

Saving a preset (shift>click on a slot) will store all current parameter settings in each voice as well as the file path of buffer contents.

Lemur interface

Control individual voices directly in the application or via the included Lemur interface (requires Lemur on iPad).

Install the interface on iPad ('monome_grainfields.jzml' located in the project folder) and make sure to provide the correct port and host settings for incoming and outgoing OSC.
