I love my Seaboard so far - absolutely stellar. The sounds are incredible.
Three big instruments that would be massive additions are a pipe organ, church organ, and an acoustic harpsichord.
"Church organ" is a bit vague, but I'm referring the instrument similar to that found in Radiohead's "Motion Picture Soundtrack" on their album Kid A. A soft, soothing sound.
Whereas "pipe organ" refers to instruments like the Leeds Town Hall Organ. The type of sound found on "No Time for Caution" on Hans Zimmer's Interstellar score.
Thanks for requesting these sounds – I agree that the Seaboard is great for developing new approaches to traditionally "1D" acoustic sounds! I'll be happy to pass these along to our sound design team. Please feel free to share any other thoughts or requests with us.
