• Installation package contains blocks of version 1 in VituixCAD\Library\Passive_blocks_V1.zip. Unzip to Library folder if old blocks are needed for conversion or useful otherwise.

2.0.3.5 (2018-06-13)

• Segment of existing hor/ver wire is splitted and junction created if user clicks intermediate point while adding new wire.

• Black dot removed from wire ends to avoid giving impression that wire is connected to another wire if it is not.

2.0.3.3 (2018-06-12)

• Fixed crash with incomplete network. Bug since 2.0.3.1 (2018-06-10).

2.0.3.2 (2018-06-11)

• Frequency range maximum increased back to 40 kHz.
• Crossover component parameter grid refreshed after changes to avoid lag in display.

2.0.3.1 (2018-06-10)

• Added "2nd order" with variable Q factor to Driver's SPL target list. Order combobox is hidden while 2nd order is selected.
• Fixed two 'Index out of range' errors when new project is created or another opened while Optimizer window is open and target is driver's SPL response.

2.0.2.2 (2018-06-06)

• Driver's SPL target curve hidden outside optimizer's frequency range constraints. Width of driver's target curve increased to 2px to improve visibility of frequency constraints.

2.0.1.0 (2018-05-29)

• Added parameters to Library blocks. Block parameter can be user question or variable with mathematical expression. Expression field of crossover component can contain either variable name or mathematical expression. Parameters are initially designed when creating new library block, and maintained with Edit library block parameters command. User parameters are adjusted and expressions evaluated to component values when block is inserted, or with Tune block... command in context menu. Block parameters and links to components are saved in project file for the next session.

2.0.0.13 (2018-05-22)

• Added filter to Block library window for limiting amount of visible files. Checkboxes for active, passive, OP amps, low, high, shelf, all-pass, peak/notch and Linkwitz Transform. See tooltips for seached keywords.

2.0.0.12 (2018-05-21)

• Library blocks are saved also as png files (with current zoom). Block selection window shows both images and names.

2.0.0.11 (2018-05-21)

• Frequency and impedance responses can be located also in project file directory with relative path name. This improves portability of project files.
• Prevented error if exported schematic image exceeds sheet boundaries.

2.0.0.10 (2018-05-20)

• Fixed bug in power dissipation graph with open or shorted resistances and drivers.
• Fixed bug in network solving with open wires and grounds.

2.0.0.9 (2018-05-20)

• User manual in English published and start commands enabled.

2.0.0.5 (2018-05-18)

• DCR of coils added to Power dissipation graph.
• Driver number added to schematic for helping identifying if the same driver (model name) has multiple instances in the crossover.

• Driver dropdown list added to Optimizer. No need to select driver from schematic to optimize driver's SPL or filter gain.

2.0.0.0 (2018-05-16)

• First beta release of version 2.
