UChord

1~2 hours of testing -> Ouh là là.

But, since they don't offer demos, I had to make a big decision to buy this.

The functionality is simple and seems very useful when experimenting with chords.
I would like to see the ability to detect chords when played on a MIDI keyboard.
Also, the chord presets section is divided into AB, but it would be easier to try out chords if there was a layout where you could see all the chords on one page.

really simple and fun. amazing...
looking forward to the next updates.

and simple chord detection is also nice.

I make music but I'm not a real musician and doesn't know music theory.

UChord is a very easy to use plugin for me, I try some others but too difficult for me.

I buy it, with 12$ intro price, it's a very cool price.
