Totally agree!

Hi,
I'm absolutely on same page with you!
Just because I'm using a midi keyboard with its own speakers, and have same issues.
All that you said should be already working in the app.

I have a stationary setup in my home with a MIDI keyboard. I use an external sound module to produce the tones for playing, so no Yousician's rompler is involved.

Nevertheless, I have to choose to use MIDI on every session. This is a computer program, and one of the strongest rules for applying IT is 'don't repeat yourself'. Yousician is making me repeat myself in a non-practice context, which is unnecessary and annoying.

Moreover, I can still hear Yousician's synth playing when I hit the keys outside of the song, producing a bit of a slapback echo to the other piano sound.

All this could be fixed easily - just make Yousician remember that I want to use MIDI and I do not want to hear its sound fonts but play with my own sounds.

Just add a tickbox to the MIDI inquiry popup that says "Use these settings in the future and don't ask me again". Then make this reversible in the settings.

While at it, add a setting there that disables the internal MIDI playable sounds altogether. I don't wish to hear those, ever.

Taken a bit further it would be useful if I could manually choose which MIDI input Yousician listens to in the settings as well.

Then there's controlling Yousician with MIDI messages, but that's another topic that I hope will see the daylight some day. Until that day we're stuck with MIDI translators.

I'm using the macOS version, and each time I start the program I have to go to Settings and select the MIDI input instead of the audio.

Could you consider making the input settings persistent?
