The Live version of TX-81Z has been designed to perfectly fit into your Ableton Live. All the included devices can be directly installed in your “Packs” section and previewed when selected in the Live browser. They have also been organized in Live standardized categories so that you can find them also in the browser’s “Categories” section. Moreover, all the sounds included in TX-81Z have similar perceived volumes and feature 5 macro control templates with volume compensation to avoid unwanted distortions.

The Kontakt version of TX-81Z includes PRIMUS, a virtual instrument with an ultra-friendly interface and a solid set of synthesizer parameters. All the sounds included in TX-81Z can be easily selected using the Waveform menu and then tweaked using 25 different filters with cutoff and resonance, one multishape LFO assignable to Filter, Volume and Pitch and two envelopes for filter and amplifier. PRIMUS implements also a Glide effect, a Unison with up to 4 stacked voices and a set of built-in effect.

Initial Release – April 2025

Our Products are generally provided as Zip file downloads which in all cases will need to be extracted and saved to your hard drive prior to installation. Details on the different file type provided and what to do with them are below.

.alp Files – These are Ableton Live Packs and will either install directly into the Packs Section of the browser of Ableton Live or ask you to save them to your hard drive. For packs that install to the library, when you double click on them you will see a pop up window asking you to confirm that installation is ok as the files are described as “Legacy”. This is fine and you are ok to proceed, the packs are created using the format for an earlier version of Live and so remain compatible with the current version.

.amxd files – These are individual MaxforLive Devices and can be stored anywhere on your hard drive. We’d advise creating a folder for them and then adding that folder as a location within the Places section of Lives Browser.
