This is UNA
UNA is an accompaniment companion for keyboard players.
If you've ever wanted a band that actually listens to *you*, this is it.
It builds on everything we learned from Midicake ARP and its parametric sequencing approach - where you don't program every note, you shape the music with parameters and let it evolve.
UNA takes that idea much further.
The big shift is that you can capture your *own* ideas, and then manipulate them.
I play a melody and then I can edit it step-by-step, or morph it into something new entirely.
I capture a chord progression next. UNA's chord track sets the mode and the mood of the whole piece — every other track stays in harmony with it.
Then a bassline — captured or generated — with its own improvisation engine that creates variation, locked to the chords and to whatever you're playing live.
And here's the payoff. In about a minute I've built a melody, a chord progression, and a bassline. Now I turn off listen mode — I can solo over the top of all of it.
To finish it off: 32 modulators that can target any parameter. So, the piece keeps evolving while you play — nothing has to stay static.
That's UNA.
