bonjour jai achete la version payante probleme la carte son est reconnu mais impossible d enregistrer pas de son et pas de clavier

If Logic works and the app don't maybe could be a problem of output routing rather than input midi...that happens usually to me, logic is a bit friendly than other programs about spitting out audio (one way or another it finds a way to send out the sound)...if you click with the arrow pointer on See Music keyboard does the program make some sounds? If it don't check the Midi/audio settings.

The main issue is that the notes you play on the keyboard are not showing up in the app? In other words, there is an issue with the MIDI connection?

In general, this issue has to do with the way the keyboard is connected to your device. There is not much I can to help with this from the perspective of the app.

- Sometimes there is a setting on your keyboard that needs to be switched on for it to actually send the MIDI data out on USB, even if it is technically connected.

- Are the notes being played on the keyboard being recognized by other MIDI apps, like Garageband or Logic?

Can you please post a video screen capture of what you're seeing?

Thank you
