If a client has an Audio Science card in thier Maestro machine, the DASrv30.exe 'must' run at a "normal" priority level. This is accomplished through the DASRV.INI file in the Maestro folder. **Note, to change settings the DA Server must be closed. In the C:\Maestro\DASRV.INI, find the setting for "SetNormalPriorityClass = " 0=off 1=on. ASI units require the setting to be 1 (on).
