# Forward Midi events to redis/OSC
# Forward Midi events to redis and OSC
Miredis hooks to all midi devices connected and listen for events. All events are forwarded to your redis server and your OSC server.
Miredis can optionnaly hook to opensourced Link protocol (200+ music & videos apps) -> "/beat" & "/bpm".
Custom events can be triggered with reranged values from one or two CC. Szz custom action types

(for cheap midi interface midisport/midiman from audio on Linux : apt-get install midisport-firmware)
(for cheap midi interface midisport/midiman support on Linux : apt-get install midisport-firmware)
## New Features
- Client example : midicontrol.py
- Added verbose mode -v
- Added redis subscribe events
- Added Clitools program selection mode for Launchpads
- Added custom redis 'key event', to be more semantic/hardware agnostic with Configuration file : miredis.json. i.e "/feedback/1/114/value" is generated each time a CC message on channel 1, CC 114 is recevied.
- Midi timecode thks to https://github.com/jeffmikels/timecode_tools.git
- CC values can be reranged, see 'custom action type'
- LJ2 custom actions for laser settings (midichannel -> laser number)
- Midi controlled python example : midicontrol.py
- Verbose mode -v
- Redis subscribe events
- Clitools program selection mode for Launchpads
- Cstom redis 'key event'. To be more semantic/hardware agnostic with configuration file miredis.json. i.e "/feedback/1/114/value" is generated each time a CC message on channel 1/ CC 114 is received.
## Custom action types (see miredis.json)
Process given CC(s), create and send result with a "name" event. Builtin types with mandatory parameters :
- 0 : note number (name, type, note)
- 7 : rerange 7 bits midi cc (0-127) to a lowend-highend number (name, type, CC, low end, high end, default value)
- 8 : rerange 7 bits midi cc (0-127) to 8 bits number (0-255) (name, type, CC, default value)
- 140 : rerange one midi cc (0-127) to 14 bits number (0-16383) (name, type, CC, default value)
- 14 : 2 cc (14 bits value) reranged to a lowend-highend number (name, type, highCC, lowCC, low end, high end, default value)
