In Studio One, like other DAWs there is a plug-in FX called Chords. It’s similar to Scaler in you can pick a key, chord and play it on the keyboard. The cool thing is that you can use it with your hardware synths as will as you VSTs. You can just route to your audio channel and you can audition the sounds of your synth the same way you can a VST. It would be a great feature to be able to use Scaler this way.
Also, can you finally read chords from audio in Studio One with the latest beta release?
