OLO was started in the spirit of PLOrk (Princeton Laptop Orchestra): each performer with a laptop, speakers, and controllers — exploring collaborative laptop musicking without a central PA.

Concept (official)

1. Laptops are instruments, performed with the same care as acoustic sections.
2. Digital possibilities and social playing are embraced.
3. Only the extended instrument speaks — no external amplification.

Equipment

Regular laptops with active studio speakers (or comparable powered monitors) so each station is audible in the ensemble without a house system.
