If you got here, you are probably one of those who just purchased an Axiom Air Mini 32 midi keyboard controller, plugged it in, and tried to have some fun with Logic Pro X.
And… surprise… IT DOESN’T WORK!
I’ve a solution.
And I’ll give it to you.
If you want to read it right now, just scroll down.
First, let’s try to understand the causes. I went through many posts reporting the same problem.
It seems that with latest Macosx update to Mojave, something has changed with the way USB 3 is managed.
In case you want additional details… go to these posts.
Potential solutions (didn’t work for me)
Many posts suggest to solve the issue with software fixes.
First by downloading e installing Hypercontrol drivers. (also here https://m-audio.com/kb/article/1684)
Secondly by checking the controller is actually sending data, for sintance by using Audio Midi Setup (by default on Macosx, just start typing “midi”) on Spotlight.
Thirdly, by working with the control surfaces in Logic…
But these didn’t work (for me), because it’s an hardware problem.
Final working Fix
The solution is simple, and was proposed in a post I can’t find now (if you have the original post, send me a message and I’ll be happy to give credits):
Do not connect Midi Keyboard straight to the USB port, but go through a USB hub, possibly a USB2 hub.
The picture below shows the working setup
As simple as this. A nice workaround… that makes eventually the whole thing work!

The European Plate Observing System (EPOS) highlights how its research infrastructure has become more efficient and user friendly by utilizing technology developed in the frame of the EU H2020 VRE4EIC project.
In the last decades quite an amount of tools, technologies and software has been developed to support and improve research throughout the entire data lifecycle. This includes software, modeling tools, and even code that can be used and re-used by researchers around the world. However, more and more emphasis has been given to the structural components that enable a Research Infrastructure to be sustainable, robust and, even most importantly, compliant to the FAIR principles. Such principles prescribe–in order to enable reproducible science–that data need to be findable, accessible, interoperable and reusable. It is usually up to research infrastructure designers, developers and managers to find the best architecture and technologies to enable FAIR to become reality in their scientific domain. However, looking transversally at science domains, it is clear that there is a number of challenges common to several communities, as evidenced by the common requirements elicitation and analysis of existing technical assets carried out both in the VRE4EIC and ENVRIplus project.
In this framework, VRE4EIC is promoting the adoption of common, standard technical solutions in order to facilitate Research Infrastructures in facing shared challenges and thus complying with FAIR principles.
This is the case of the European Plate Observing System (EPOS), a Distributed Research Infrastructure long-term plan to facilitate integrated use of data, data products, and facilities from distributed research infrastructures for solid Earth science in Europe.
In order to enable accessibility (the “A” of FAIR), the EPOS central hub, that provides access to a wealth of different types of data and services from communities, had to implement appropriate Authorization mechanisms. Such mechanisms are usually referred to as “AAAI”, which stands for Authentication, Authorization, and Accounting Infrastructure. Instead of creating such an infrastructure “from scratch”, EPOS took advantage of the existing VRE4EIC “AAAI Service” building block. This component provides a “plug-and-play” solution for the authentication of users, and in addition it integrates different authentication mechanisms from various AAI providers (e.g. EDUGAIN, Facebook, Google and others) in one single system. Due to its integrability into service-based architecture, it can be easily plugged into micro-services-oriented architectures, such as the one of EPOS.
Figure 1: Example of integration of VRE4EIC Authentication services (AAAI) into EPOS central hub Graphic User Interface (GUI). The login box is rendered on the EPOS GUI, but actually managed and ran by VRE4EIC Authentication service building block. Such component is part of the VRE4EIC prototype and runs on VRE4EIC servers made available by project partners (in this case CNR ISTI – Pisa).
The EPOS User Interface is presented in Figure 1. It enables the discovery and search of datasets in the solid Earth domain, which includes several communities such as Seismology, GPS, satellite data, volcanic observatories and others. An authentication widget is also available for access to specific dataset. The authentication in this case is managed by the VRE4EIC AAAI service component, that is simply “plugged-in” into EPOS main system.
Starting from this first pilot, EPOS has also benefitted from VRE4EIC studies and developments in other fields. For instance for the workflow management and the metadata system architecture (both projects use the CERIF model).
The EPOS use case has several important implications. The first one is that this pilot has demonstrated the suitability of the strategy adopted by VRE4EIC for supporting and enhancing e-Research Infrastructures, in particular with respect to the AAAI service.
The second one, related to research infrastructure sustainability, is that it saved efforts in integrating authentication services on EPOS, with all related technical and security issues, not to counting the development efforts that were optimized by adopting an EU-funded solution.
Third, on the user side, it allows end users to access through existing credentials from Facebook, eduGAIN, and other Identity Providers, to log in easily to EPOS or any other Research Infrastructure enhanced by VRE4EIC Authentication service.
Now, a future-oriented exercise is due: imagine that many other research infrastructures would use such shared solutions produced by VRE4EIC. How much development and sustainability efforts would they save by integrating in an easy way metadata catalogue services, AAAI services, and other common solutions?
The answer is not trivial, also because other players are available on the EU landscape. However, the expertise brought in by a pool of scientist and engineers in VRE4EIC, strongly connected with the communities, and with skills in the integration of several research infrastructures in various domains, is doubtless precious and capable of optimizing the technical dimension and sustainability, as demonstrated by the EPOS pilot.

Well, it’s weird: I’m at the same time proud and shy about the video we released in the framework of VRE4EIC project.
It was funny: I had just landed at Schipol airport and then rushed to TUDelft university… and I found myself at the New Media Center in front of a camera, in a soundproof studio with a bright-green background, just a few people watching (or staring at? :)) me behind the soundproof glass and I had to start talking with my south European English accent (that’s the embarrassing part :))
Well, I think I realized how fishes feel in their fish-bowls!
By the way, the people from the studio were great and patient, and they explained clearly how it would work. So we just had to leverage on the huge work we did previously, that is to say the preparation of the video – lecture.
The topic of the videos is How research Infrastructures can take advantage of interoperable VRE building blocks.
In the first part I explained what research infrastructures are, what distributed research infrastructures can provide to users, and what is their governmental and technical organisation. Real examples were be done by discussing the EPOS use case.
In the second part the focus was on how interoperable building blocks developed in the framework of VRE4EIC can be used to enhance Functionalities of Research Infrastructures. An example was be illustrated by discussing and analysing the EPOS use case.
I hope you enjoy the two videos.
A debate is currently active, mostly between some of the major players in the field of Virtual Research Environments, i.e. VRE4EIC and other European project teams. They are trying to define commonalities and differences among Virtual Research Environments (VRE), Science Gateways (SG) as used in North America and Virtual Laboratories (VL) as used in Australia.
A general agreement was found on the definition of a VRE, that usually provides not only access to ICT services, data, software components and equipment but also provides a collaborative working environment for cooperation and supports the research lifecycle from idea to publication while also supporting research management and administration.
However different positions are taken with respect to the SGs and VLs, considered both as synonyms or as different objects: SGs are mainly portals to access data and VLs provide a collection of datasets, software and computing resources for researchers to construct their own environment.
