JBL Smaart Pro Version 2.1 Release Notes Changes Since Version 2.0 Real-Time Module Fixes * Trace shift will no longer invert when turning on FPPO, or changing sample rates in Swapped Transfer Function Mode. * Various problems resulting from interaction between Phase Display and Delay Locator features have been corrected. * FPPO setting now saved in System Presets during program exit. * "Ghosted" octave bars now draw properly when Solid or 3D bars are selected. * Load Configuration and Import Configuration commands now save changes to current Configuration before executing. * Import and Export Configuration commands are no longer disabled in EQ mode. * Coherence plot color now respects Color Scheme selection. * Delay Locator now uses selected wave device instead of Windows default. * Locator recording process changed to help prevent conflicts with some sound hardware drivers. * EQ configuration now reread after Load and Import Configuration operations. Real-Time Module Feature Changes * "Don't use large wave buffers" option added to Device Options palette to address a problem occurring in some sound hardware drivers when greater-than 64k wave buffers were required. * "Show Arrow Cursor" choices removed from cursor options (hidden arrow cursor could cause problems in some situations). * Clicking outside the plot in Delay Locator mode now changes both X and Y axes to default (full-scale) view. * The Locked Cursor readout now includes a +/- notation In Delay Locator mode to indicate the polarity of the cursor amplitude (in all Amplitude Scale views). * Peak location in Delay locator now uses the absolute value of amplitudes to allow the Locked Cursor to lock on a negative peak (if its amplitude is greater than the highest positive peak) when Linear Amplitude Scaling is used. * A number of changes have been made to the SmaartEQ (MIDI-controllable EQ) control interface to more closely emulate the behavior of the hardware control interface and streamline setup and use of the EQ - particularly in live sound applications. Please refer to the revised Real-Time module Help file (included in this update) for details. * Switching between Mono and Stereo EQ modes now gives warning to prevent accidental loss of filter settings. * When "Dragging" a filter, using the mouse in EQ mode, the Real-Time module now waits until the move is completed before sending the revised filter settings to the EQ unit (to help prevent overrunning the EQ's command buffers). New Real-Time Module Features: Reference Comment List Field: The Reference Comment text field (located on the Reference Info Bar) has been changed to a "combo box" that preserves the 20 most recent comments used in a drop down list. Separate lists are maintained for 2-Channel and Transfer Function comments. The selected comment is still fully editable. Load/Save All Reference Traces: A new group save feature allows you to save and reload the contents of all 40 (2-Channel and Transfer Function) Reference Registers, including text comments, in a single operation. This feature is accessed through the Load All and Save All buttons added to the General tab of the Reference Information dialog box. The Save All command stores the current contents of all Reference Registers in a single Reference Group (*.rgp) file. You can enter a comment for the group file when saving that will be visible (in the Load Group File dialog box) during subsequent Load All operations. The Load All command allows you to reload a previously-saved Reference Group file. Please refer to the revised Real-Time module Help file (included in this update) for more information. Analysis Module Fixes * Audio Playback rewritten to use much less memory and correct possible memory error. * Audio Playback now respects Time Zoom selection in Time Display, Time Slice, and Spectrograph Display modes. * Possible conflicts between Audio Playback, File 2 time offset, Time Zoom, functions have been addressed. * File 2 time offset value now cleared when file 2 closed. * A number of unnecessary screen redraws have been eliminated. * Status bar dB readout now correct in full-scale Spectrograph. * Problems recording over current file corrected. * Power spectrum calculation no longer treats negative peaks as positive. JBL-Smaart Pro User's Manual Superseded Information (Version 2.1) A number of changes have been made to the External EQ control features described on pages 77-80 of the JBL-Smaart Pro User's Manual. For up-to-date information on these features, please refer to the revised Real-Time module Help file (included in this update) or download the Supplement to the JBL-Smaart Pro User's Manual for version 2.1. The supplement will be made available in Adobe PDF format on the JBL Professional web site (www.jblpro.com) or the SIA Software Company, Inc. web site at www.siasoft.com. Omissions A small number of changes were made to the Locked Cursor section of the Real-Time module Control menu and MIDI EQ control panel after the JBL-Smaart Pro User's Manual went to print. In the Locked Cursor section of the Control menu, three commands were added: * Remove - clears the locked cursor * Assign to Current Delay - Assigns the Locked Cursor time coordinate as the current working Delay Time (Delay Locator mode) * Assign to Delay Preset (F6 - F10) - Selecting this command in Delay Locator mode assigns the Locked Cursor time coordinate to both the current working Delay Time and the specified Delay Preset register then exits Delay Locator mode in one step. For more information about the menu commands listed above, please refer to the Control Menu section under Real-Time Module Commands in the Real-Time module on-line help file. Errata * On page 11 under Step 13, second bullet point, the user's manual incorrectly states, "To find the highest point on the top trace, press [Ctrl] + [P] on the keyboard." The correct keyboard command for the Find Peak function is actually [Shift] + [P]. * On page 36 the inset text box states, "Important Note: JBL-Smaart's Delay Locator requires the FFT Time Constant value to be larger than the decay of the system under test." This would more properly be written "Important Note: The JBL-Smaart Pro Delay Locator requires the FFT Time Constant value to be larger than the decay time of the system under test." (where decay time is defined as the period of time from when a stimulus input ends until the remaining energy dissipates to a level that is indistinguishable from the background noise in the room). Supported MIDI EQ devices The JBL-Smaart Pro Real-Time module currently supports the following MIDI Controllable equalizers: JBL SEQ592 SmaartEQ(tm) BSS Varicurve(r) FCS 920 BSS Varicurve(r) FCS 926 Interim Maintenance Updates and Support Information Maintenance updates, user support documents and other information of interest to JBL-Smaart and JBL-Smaart Pro users will be posted on both the JBL Professional web site (www.jblpro.com) and the SIA Software Company, Inc. web site (www.siasoft.com) as they become available.
