MIDI Scope is currently only available on the github for corporate members of the MIDI Association.
By MIDI Association
you mean the MMA
That is unfortunate. But the consequence is that we, open source developers, are going to release new versions of our products for the time being without supporting the MIDI 2.0 specification, as we are not able to test it. For me, it would be in the best interest of the MMA members to incentivate the release of open source synths, and all kind of open source tools leveraging the new specification...
In my opinion, this is the same mindset as before the MIDI Association, when the specifications were behind a paywall. Now the specifications are available for download to everybody associated, but the test tools are not. It has sense that the MMA members could enjoy some advantage to release industrial products conforming the MIDI 2.0 specification, but the fact is that there are very little amount of MIDI 2.0 products out there in 2021 yet. The only product that is marketed as "MIDI 2.0 ready" is an expensive Roland controller, but what is a MIDI controller without at least one MIDI Synth to talk to?
Promise of Vast Improvements… But It Might Take Awhile
