This post is about a user instrument available for the Nebulae 2 (Neb2) eurorack module.

The eurorack module and most of the underlying software is made by Qu-Bit Electronix. Thank you!

The instrument available here is made by an enthusiast for these various sound platforms. I am not affiliated with Qu-Bit and the software hasn't been officially sanctioned by them. (The software is pretty cool, though!)

The name of the instrument in this post is: WindowAltSwap05.instr

To use this file:

Click the DOWNLOAD button to the right -->
Open the .zip file that downloads to your computer.
It will unzip to a folder with 2 files inside:

a) a README file with a few instructions, and
b) the instrument file to be installed on your module

Follow Qu-Bit's instructions for loading instrument files on your Neb2.


The instrument that accompanies this Readme file is called: WindowAltSwap05.instr

It is based on the newSize05danish instrument, which is based on the default instrument (a_granularlooper.instr) of the Neb2.

WindowAltSwap05.instr was developed to perform similarly to the newSize05danish instrument. The main difference is: the 'window' controls (both knob and CV) have been swapped with the 'windowAlt' controls.

Window controls:

When using this instrument, the 'window' controls determine the number of grains are masked (allowed to continue to the output).

In general, the higher the masking, the fewer the number of grains are allowed to get through. However, because the end effect is the number of grains allowed through, I have reversed the effect of using the 'window' controls: 

Increasing the 'window' controls increases the number of grains that are allowed through. (Note that in the default instrument, increasing the 'windowAlt' control increased the masking, thereby decreasing the number of grains that were allowed through.)


WindowAlt controls: 

When using this instrument, the 'windowAlt' control determines which window envelope is applied to the grains. While holding the 'source' button, turning the 'window' knob changes the window envelope, in the same manner as changing the window envelope in the default instrument.

If there are other differences, I have forgotten to mention them, or they are unintended artifacts of the code. Please check back here from time to time for the most current information.

Happy wiggling!


This instrument works best when the module is running the latest version of danish## firmware, found on this site.

The instrument available here is not an official instrument from Qu-Bit. I think the software described in this post works well, but recognize that software is like speech - sometimes we express things that are not exactly what we meant or intended. Please use these instruments on your module at your own risk. (It is recommended that you keep a copy of the official firmware file from Qu-Bit, in case you need to reinstall an official version to your module.)
