Description

This is a massive collection of 1387 *.adv presets for the Max Instrument "Opfour" by Katsuhiro Chiba.

Opfour is a nearly perfect clone of the TX81Z, Yamaha's classic FM synth.

This pack contains only *.adv presets and not the device itself.

You can download the device from the Ableton website:

I'm not the creator of these patches, i've just imported some free SysEx files.

I've used this TX81Z programmer to import the patches to Opfour:
