Luckily, we have a instrument folder called “Elements” that contain basic sounds that you can build upon - using the ability to expand an instrument and load samples from within it, we can load the sample “ Sine 16.351 Hz” from the instrument called Chip - Sine.xrni You can’t cook without ingredients, and in this case our main ingredient would be a sine-wave. This will make the base frequency sit nice and comfortable as the middle 4th layer, with the possibility to add extra harmonics both above and below this tone Step 2: Gathering ingredients The 1/1 ratio refers to the fundamental frequency - in this case we aim for 1720Hz - exactly two octaves above the standard base frequency of 440Hz. And since this is a traditional organ-style sound, we want to add subharmonics (fractions of the topmost frequency) in the following manner: Layer 1 : 16 In practical terms, this means stacking 8 differently tuned sinewaves on top of each other. So, we have set out to recreate a drawbar organ. The file is called Drawbar Organ.xrni, located within the folder named “Electric” Step 1: The fundamentals Tip: to listen to the final instrument, you can open Renoise right away and and use the Disk Browser to navigate to the factory content (within the instrument tab). You could easily take the resulting instrument into new territory by adding your own effects, using an alternative tuning scheme or by replacing the individual samples. Note that this is not an introduction to advanced instrument-design as such, but rather a quick guide to pick up on some of the aspects of the new Renoise 3.0 sampler - the sample list/properties, modulation and macros. At the end of the exercise, we should be able to control our creation via macros, too. This instrument is useful as a general purpose tone-generator, able to create sounds with a wide range of harmonics. In this exercise, we will recreate one of the instruments that come with Renoise 3, a drawbar organ emulation.
