What is Snowgrains?
Snowgrains is a patch for the Organelle M. It features audio input, a subtractive synth and most importantly a granular synth. The granular synth can sample sound from the microphone / line in, and from the subtractive synth. This manual is a quick referance guide to what all the different parameters does. It does require basic knowledge of the device itself.
Organelle 1 vs Organelle M
This patch only works on the Organelle M and not on the original device.
Installing the right version
There are two different versions.
- Full version
- Light version
This is becausethe patch is using two external libraries:
- Cyclone
- Else
If you have these two libraries installed already via Deken you can download the light version. If you do not have these installed you download the full version. If you are unsure just download the full version.
The keyboard
The keyboard notes function change depending on what page you have selected with the encoder.
Page 1-2: the notes control the subtractive synth
On page 1 and 2 the keyboard notes control the pitch of the subtractive synth. If the arpeggiator is turned OFF every other note you play on the keyboard will be transposed up one octave. If the arpeggiator is turned ON it will automaticly arpeggiate between the two octaves.
Page 3-4: the notes control the granular synth
On page 3 and 4 the keyboard notes control the pitch of the granular synth. The left part of the keyboard transposes the granular synth in semitones while the right part of the keyboard controls the granular synth in octaves. See illustration.
The LED
The LED shows the recording status for the granular synth.
| LED | Meaning |
|---|---|
| Off | No recording is happening right now |
| Flashing red | The granular synth is currently recording |
| Blue | The granular synth is transitioning (because transition is set to slow) and will soon start recording |
External midi
Ps this function only work correctly when using midi over USB. If you want to control parameters with MIDI CC please do midi over usb. If you are only going to play notes you can use the midi trs port. I am in contact with C&G to figure this out.
When you turn on external midi control (page 8 parameter 4) you can control everything with external midi. When page 8 is selected you can press the AUX button to scroll thru the list of midi CC numbers.
Ps. Activating or deactivating external midi control will also:
- Trigger the granular synth to do a new recording
- Change the buffer size and add a bit of latency.
