The Etherwave Standard Pitch Extension module greatly enhances the linearity of the Etherwave Standard and Etherwave PLUS theremins. The pitch field will be extended with up to two octaves in the bass register, while the high register remains unaffected. The timbre is also affected, making the sound smoother. A detailed explanation of the module can be found here.
Installation instructions and a video walkthrough can be found on this page.
Disclaimer: the module may work less efficient with older Etherwave theremins, sold under the Big Briar brand. Installation on those theremins may differ from the steps of the manual. If you have one of the earlier Etherwaves, we can give you the information required for a succesfull installation.
The module is shipped without tracking. If you do want tracking, please select this option in the shopping cart.
