Intense Tech with Defense Mech – New Noise and 9.1.0 News!
-Posted January 17th, 2021 by [DEFENSE MECHANISM](https://defensemech.com)
Hello and welcome to another edition of Intense Tech! In this article, we'll talk about the changes
in the recently-released version 9.1.0 of LSDj! This version is exciting, although it does include
some changes that will potentially break the noise instruments in your existing songs. In order to
prepare you for the changes, let's take a closer look!

Channel Changes

If you've ever thought the LSDj noise channel was confusing, you are not alone! Even though I
previously wrote an [article explaining its inner
workings](https://defensemech.com/intense-tech/en/17-the-joys-of-noise.md.html), it was not enough
to demystify its strange behavior. Clearly, the usability could be improved, and this prompted a
reorganization of the entire noise channel for version 9.1.0. The new organization places all noise
notes in order of frequency: first, the long-loop noises are ordered lowest to highest from notes
`00` to `3B`. Above that, the short-loop notes are organized lowest to highest, from octaves -9
(negative 9) to 8, using note names to represent the notes that each frequency most closely matches
(C, D, F, and G#). Each octave from -9 through 4 contains these four notes; octaves 5 through 8 only
contain the note C (except for an extra F in octave 5).
If you load up an existing song or save file into version 9.1.0, your noise notes will be
automatically converted -- however, any transpose or S command values will not. As a result, I've
devised this handy noise converter if you are interested in manually changing the values in the
noise channel phrases or tables. (You can also [find this converter without the article
here](https://defensem3ch.github.io/noise-convert).)
