With some (home grown) patches Icarus outputs something at -70 DBFS when no note is played. Does anybody know what could cause this?
Hello Flexion,
some filters do have self oscillation. This can result in output without notes playing. Some of the insert effects do output noise as lo-fi effect.
There is also a very small DC. It prevents the following plugins from denormals. As a result the CPU load is lowered drastically.
