The library is named after a legendary club that opened in Tokyo in 1972. A pioneering space for musical experiments.


OZ empowers you with extensive sound-shaping controls, granting the freedom to mold and transform the sound to your liking. With the “Glide” control slider, you can produce legato and portamento transitions.

*Sound & Recording




One of my discoveries from 2022 was definitely the very young sample forge from Norway, which has already released a remarkable number of fine boutique libraries in its first year. 


The latest addition last year was Oz. The instrument sampled here is a Japanese ACE GT-7 organ, built in 1971 and still in its original condition to this day. Five different signals were sampled: Speaker, Room, Spring-Reverb, Leslie, and the DI signal.

In direct access, there is an additional convolution hall (with several IRs), a delay, a control for an LFO, and a separate vibrato. Everything can be fine-tuned in a submenu. A recurring element of Wrongtools instruments is an optionally displayed XY field where all sorts of sound design are hidden. Behind flowery names like Digidust, Sadist, or Huldra, you will find effects that twist the sound quite peculiarly. The whole thing can also be wonderfully automated via CC-Learn. However, it takes a bit of experimental spirit to discover everything that lies behind it.

Fortunately, many presets are already included. There are the ‘normal’ patches of the sampled instrument with its various sound possibilities, which are also combined in some multis that can be loaded.


As is usual with Wrongtools, there is then the – as I find – often more exciting part: the sound design patches. For these, the original recordings were re-recorded using external effects, pedals, amps, and tape, creating soundscapes and drones, playful tinkling, and quirky interpretations of the original instrument. If you like something like this, you should also listen to ‘Plateau’ (see below).

If I had to criticize something, it would be that the minimalist GUIs with often very small controls are not always immediately intuitive to use. There is an enlarged view, but it is very hidden.

It’s gratifying that many of the instruments from the Norwegians are at a pleasant price level. Many cost between 30-40€, the extensive and very creative ‘Featherstone Strings’ are available as the most expensive library for 150€.

For starters, there are also some free instruments available. It’s definitely worth subscribing to the newsletter, as new freebies are said to be added regularly.
