Freeze if wished. Mangoes can be frozen. The skin will turn black but the flesh will stay in good condition (it will be just a little softer than prior to freezing). You can freeze either the entire mango or you can freeze chopped up pieces.
James, you need to do a little research on ASIO Direct Monitoring. It's a standard tha allows an ASIO host to enable hardware monitoring in an interface that supports it. This bypasses The A/D/A converters and is true, zero-latency direct monitoring.
Part of the Peripherals glossary: ASIO (Audio Stream Input/Output), developed by Steinberg, is a cross-platform, multi-channel audio transfer protocol that is being adopted by many of the manufacturers of audio /MIDI sequencing applications. It allows software to have access to the multi-channel capabilities of a wide range of powerful sound cards.
