BTW. The code works fine without the A. Exp. cape!
Here is the SC header, and attached the project/
IDE/capelet settings
s = Server.default;
s.options.numAnalogInChannels = 4;
s.options.numAnalogOutChannels = 4;
s.options.numDigitalChannels = 16;
s.options.blockSize = 16;
s.options.numInputBusChannels = 4;
s.options.numOutputBusChannels = 4;
s.options.postln;
