Version 2.2.3 includes the following bug fixes and improvements:

new in version 2.2.3

- new Combined presets settings for improved presets packs experience
(see 3.7, Combined Presets, in the updated manual)
- the Mixer can now be scrolled horizontally by pressing down the middle button of the mouse
(if one is available) and dragging
- adding an X-Drum for which one or more close mics are not assigned will result in the
'Microphone Assignment' button flashing blue

improved in version 2.2.3

- new E-drum MIDI preset mapping boosting improved support for hi-end Yamaha and Roland modules
- articulations with only Hard and Soft hits should play back in a fashion closer to S1 and EZdrummer but with more consistent velvol response*
- includes changes related to mouse wheel events handling for improved operation (mostly obvious on Mac)

fixed in version 2.2.3

- CPU surges due to using effects in the Mixer should no longer be encountered
- fixed crashes occurring when nothing was routed to OUT 1/2 and the sampler rate was different than 44.1K
- fixed a crash in the instrument preview handling when using non-updated early EZX-s
- cured a family of bugs related to removing X-drums other than the last in order sequence
- fixed a bug that caused crashes during bounces when there were more than 32 microphones
- fixed an additional bouncing bug when X-mics were present in the project
- the typeface used in the interface should no longer disappear when multiple hosts are accessing the plugin
- S1 legacy path should no longer accept paths to a new generation SDX (or EZX for that matter)
- gate and enable/disable buttons in the Velocity Ctrl section should now work on multiple selection and not just a single target
- cancelling a Combined preset load will no longer result in a check mark for that preset
- the X-Drum Sound Library menu gets its entries unchecked when a new X-drum is selected
- the X-Drum Sound Library menu label is now a title only and can not be selected
- layout on the Settings page has been revised to group related options together
- MidiNode factory presets as finalized a couple of releases back are restored
- it is now possible to rename a Mixer channel to its internal name

* due to nature of this change, note that your project may play back differently than before the update. It is unlikely to affect many users but customers using the Latin Percussion EZX in particular are advised to check their projects to make sure playback is as expected (or better).
