Using this Magma CTRL case is easy. Just unzip the case, place your Roland SP - 404, SP - 404A, or SP - 404SX inside (but remember, it won't fit the Sp - 404MKII). You can adjust the removable foam to protect the knobs and faders. When you're ready to go, zip it up and carry it by the padded handle. It can also be put into larger backpacks or bags. For maintenance, keep it in a dry place. If it gets dirty, you can gently wipe it with a soft, damp cloth. Avoid exposing it to extreme temperatures or sharp objects that could damage the durashock molded EVA foam.
