 **Em + Latch** (emulate with latch) mode is basically the same as //Emulate// mode, except that you don't have to hold the sustain pedal down. Instead, you press and release the pedal once to activate sustain (the letters "SUS" will appear in green text next to the menu), and a second time to de-activate it. **Em + Latch** (emulate with latch) mode is basically the same as //Emulate// mode, except that you don't have to hold the sustain pedal down.

-==== Headline ====+===== Suppressing events ===== 
 +The **Suppress (filter OUT)** section is mainly about removing selected events from the MIDI data stream, but the **Repeated** checkbox is an exception; it actually //inserts// events when required.
  
 +==== All Notes ====
 +Checking the //All notes// box causes //MIDI Filter// to suppress all MIDI note-on and note-off events. This can be useful when you want to pass only e.g. CC events to the next plug-in in the chain.
  
-===== Pitch Bend filtering ===== +==== Repeated ==== 
-Use the **Suppress PB** checkbox to filter Pitch Bend events out of the MIDI stream.+Most MIDI keyboards will transmit a MIDI //note-on// event when a key is pressed down, and a corresponding //note-off// event when the key is released. A few keyboards (in particular Casio's //Privia// digital pianos) do not send //note-off// events during //legato// runs, and this can confuse some software instrument plug-ins (in particular KORG's [[https://www.korg.com/us/products/software/kc_triton/|TRITON]]).
  
-This is useful when you would like only some instrument layers to respond to Pitch Bend.+Checking the **Repeated** box will cause MIDI Filter detect when //note-off// events are missing, and re-insert them into the output stream (immediately before the next //note-on//).
  
-===== Mod Wheel filtering ===== +==== Pitch Bend  and AfterTouch filtering ==== 
-Use the **Suppress MW** checkbox to filter Mod Wheel (CC#1) events out of the MIDI stream.+When working with multiple instrument layers, you may occasionally want to ensure that only some layers respond to Pitch Bend or Channel Pressure (aka //aftertouch// events). 
 +  * Check the **Suppress PB** box to filter Pitch Bend events out of the MIDI stream
 +  * Check the **AfterTouch** box to filter out both Channel Pressure (mono aftertouch) and Aftertouch (i.e., polyphonic aftertouch) events.
  
-This is useful when you would like only some instrument layers to respond to CC#1.+To filter out mod-wheel events, see below under CC filtering. 
 + 
 +==== System Common, System Exclusive, and Real-Time filtering ==== 
 +A few MIDI controllers transmit MIDI //System Common//, //System Exclusive// (aka //SysEx//), and //Real-Time// messages, and there are rare cases of plug-ins which may get confused by these. 
 +  * Check the **SysComm/SysEx/RealTime** box to filter all such events out of the MIDI stream. 
 + 
 +==== Mod Wheel and other Continuous Controller (CC) filtering ==== 
 +An earlier version of MIDI Filter featured a checkbox to filter out Mod Wheel (CC#1) events. This has been expanded to a set of six buttons as follows: 
 +  * By default, each button is labeled **cc?**, indicating "no filtering" 
 +  * Click any button to open a menu of MIDI CC numbers and their associated standard names 
 +  * Select any CC item on the menu to filter out that specific CC 
 +  * **Note CC#1 is mod wheel**; this is the one you will most often want to suppress 
 +  * Select NONE (the first menu item) to revert the button back to **cc?** (inactive)
