+DSP License, expands ULN2+2d and 2882+2d allowing modular effect construction. Comes with many predesigned effects. While the 2d Card includes the basic processing bundle with every card, you can add a +DSP license to your box at any time. Adding a +DSP license will allow you to take advantage of the greatly increased processing power of the new DSP and the ease of inserting Plug-ins directly into mixer channels. If your unit is already a +DSP unit, then you already have a +DSP license. But if your unit doesn't already include +DSP, you can add a license without any additional physical changes to your hardware. The +DSP license includes a variety of additional Plug-ins including Multi-band EQs, Compressor, Limiter, Distortion Processors, and many more. With the +DSP license, you also gain access to insertable graphs which allow you to build your own “Secret Weapon” processors — wrapped up, phase compensated graphs of Plug-ins that may be re-inserted on demand. System-wide +DSP Licensing: MIO Console v.5 automatically extends any +DSP license on any attached box to all the boxes attached to your system (for boxes that are 2d Expanded) while the boxes are attached. What this means is that you can use any +DSP Plug-in or macro on any box in your system, as long as at least one +DSP licensed box is attached. If you need to store +DSP Plug-ins in persistent states or tend to split your boxes into multiple systems, you will need to license each box that needs to use the +DSP license independently.
