Filter types... ?
[ See above, the filter acts on the protocol of the midi message. Each midi message has 3 parts, the filter can work on sysx/controllers and global messages.

Filter Hardware or software... ?
[ Filter hardware intercepts the midi in transit and filters it, all the filtering is done by software embedded in an EPROM. e.g. ANATEK POCKET FILTER-(only available used, ceased production 1998).
Software filters -stand alone or inside sequencers dominate today.

Old midi controller filters... ?
[ Old midi pre 1983 standard, most of these devices send program changes and hanging notes all the time, the trick here is to turn OMNI (Omna- Latin for ALL) OFF by using controller 124.
This usually sets the device to RX & TX on Channel 1.
Examples would be Kawai SX240 Roland JX3P Crumar/Chase BIT1.
A Hardware filter will do a similar job but in the case of the Anatek you have to hold down 15 keys to set an OMNI on keyboard to channel 1.

Example ... ?
[ Filter on your module or keyboard, go to midi setup or system, turn off program change receive this is a basic example of filtering.
More complicated filtering requires the correct channel or port, you can record with the information and then choose list all similar items and then remove them or pack them into a different channel.
Most common and easiest is to filter via the sequencer.
