When a PLG-AN, -DX, -PF, or -VL Plug-in Board is first installed into a unit, the 'INT' (Internal) Voice Bank for the [PLG1] and [PLG2] buttons ([PLG] on the S30) does not contain any Voice Data; this Data must be loaded into the unit from the diskette included with the Board. There are, however, 'Board' Voices which are resident on the Board itself. If a Board Voice Bank has been selected for the Plug-in Board, the Voices in it will sound ''dry'', because they have not been configured to use Effects. Once the Internal Voice (and Effects) settings have been loaded in from the diskette, and the Bank is changed to 'INT', the Effects will be heard on the Voices.
