Here are details of the OAS system and demos of the latest OAS 7 taken from the EX 1 Expander, which is the same as the Ikarus but without the keyboard. (The sound system is the same on all models)
No external samples or VSTs were used
You can listen to the tracks Direct or Download them.
I hope you enjoy

Bill
