Plugin Boutique’s rather brilliant compositional assistant plugin, Scaler, automatically detects the closest scale to an incoming sequence of MIDI notes, then suggests a collection of chords that would work well with it, and lets you arrange them into a progression. In our review in 253 (9/10), we described it as a “powerful aid for musicians of all ability levels”.
