This is a Native Instruments Kontakt patch based on Bass Flute samples done at University of Iowa by Lawrence Fritts, Director of the Electronic Music Studios and Professor of Composition.

http://theremin.music.uiowa.edu/MIS.html

The samples are not well-suited to producing a playable instrument, due to variations in pitch, envelope, and timing. I've taken several measures to mitigate that, including blending notes pitch-shifted variants, and incomplete editing of the start timing and pitch correction.

I hope to further improve the patch, but since bass flute patches seem to be almost non-existent (and I'm aware of no other free version at all) I'm making it available in its current form.

You need the full version of Kontakt 6 (or higher).

First, be sure you have git-lfs installed.

Then clone the repository into a local directory:

git clone https://github.com/BobKerns/BassFlute.git
cd BassFlute
git lfs install --local

The last line above is needed to bring in the sample files, as they are stored separately using git-lfs. You only need to do this once, after that, git hooks manage it automatically.

Open Kontakt, and using its file browser, navigate to the file Bass Flute.nki, double click and it should load.
