First, a big up for hookpad I use now for more than one year. It has drastically enhanced my perception of composing music and my understanding of music theory.
One really nice thing I wish to see one day in hookpad is the ability to propose some harmonic paths when going from one key to another, changing mode or not.
A good example is what is proposed in the Plugin Boutique Scaler 2 plugin for major DAWs. You tell from where you’re leaving a key (for example the fifth degree of the C minor key, where you want to go (for example the first degree of the G minor key, and it proposes you different paths based on parallel scale, secondary dominats or mediants. The progressions could be proposed like it’s done in the magic panel by selector the destination scale (it’s just a suggestion)
But once again, a great thank you.
