M5000: MD2, license levels and MultiBus feature explained

Question

Please explain the license levels for the MD2, and how it relates to the MultiBus feature.

Answer

License levels:

Buying a MD2 license gives you a MD-2 license level 1.

MD2 license level 1 means that preset 200-214 can only be used on one DSP module at a time. Each additional level cost only half the price of level 1.

If the M5000 has MD2 license level 2, it means that preset 200-214 can be used on two DSP modules at the same time etc.
However, running preset 214 (Toolbox) on one DSP module, and preset 01-213 on a second DSP module only requires MD2 license Level 1! This specific situation is intended for the MultiBus feature.

The advantage of MultiBus:

The MultiBus feature enables the user to insert a second DSP module -- internally -- while running the Digital ToolboxTM. It is thus possible to make use of all the features in the MD2 in the same signal path simulatneously.

Note: DSP-1 modules with serial numbers lower than 631800 and DSP-2 modules with serial numbers lower than 610775 do not have the MultiBus feature installed. Without the MultiBus Feature it will not be possible to set the parameter INSERT to ON.

You can check for the MultiBus feature in this way:

  1. Press UTILITY button
  2. Select MENU CONFIG and select SHOW CONFIG, then press DO.
  3. Now the display shows the module configuration for the selected device. The DSP-module is displayed in one of these six ways: DSP-1, DSP-1+, DSP-1+B, DSP-2, DSP-2+, DSP-2+B Only the two combinations with the letter B (DSP-1+B, DSP-2+B) means the MultiBus Feature is installed.
  4. Press UNDO to leave the SHOW CONFIG page.

How to use the MultiBus feature:

  1. Select preset 214 at the DSP-module set to address 1.
  2. Press the EDIT button.
  3. Press the PAGE right button until the parameter INSERT shows up.
  4. Set the parameter INSERT to ON.
  5. Press the device selector button to select the DSP-module set to address 2.
  6. Select (for instance) preset 202 at this DSP-module.
  7. Press the UTILITY button.
  8. Dial PROGRAM wheel until MENU I/O shows up.
  9. Dial wheel A until parameter I/O reads INSERT.

Now the DSP-module on address 2 is internally inserted into the signal path on the DSP module on address 1. (See TOOLBOX algorithm description in the M5000 Owners Manual, BASIC ALGORITHM section).

Note: the DSP module on address 2 can only be inserted in the DSP module on address 1 and vice versa. Similarly, the DSP module on address 4 can only be inserted in the DSP module on address 3.
