// What players say
This weekend I installed MelodyMatrix and connected it to my father's keyboard, and together we enjoyed using it. He's a retired teacher from the Maastricht Conservatory with a technical streak like mine. He loved exploring the histograms and statistical displays, and the live data streaming from his keyboard to my laptop.

I've only had a short time with MelodyMatrix so far, but I'm already impressed. It instantly shows the chords I'm playing along with their function. This is a really nice touch that makes the whole thing feel musical and educational at the same time. The interface is clean, well-organised and genuinely beautiful to look at. Off to a great start!

I just discovered MelodyMatrix and it's quite amazing! And it's a father-son project, that's even more cool. I already installed the software and played around with it, it's so fun!

Questions, answered

What do I get for free?

The Forever Free plan lets you use most of the app and try it out. Grab a license when you want the extended features like recording and extra views.

What's the difference between License, Supporter and Sponsor?

All three unlock the full app for life. Supporters get their name listed on the site and in the app; Sponsors get their logo added too. It's a way to back development at the level that feels right.

Is it a subscription?

No — every paid tier is a one-time lifetime license and includes all future updates.
