Legato Performance Combos sounds very intriguing -- any details on which combinations that might entail?
If it's open to influence, I'd love to see some cross-section (woodwinds + brass + strings) combos, since there are fewer of them available. Maybe Oboes + Clarinets with Bassoons + Horns an octave below, or something more eccentric like Clarinet + Violas (con sord) with Tuba an octave under.
