+# Ruby Wrapper for Voicemeeter API
+
+This gem offers a Ruby interface for the Voicemeeter Remote C API.
+
+For an outline of past/future changes refer to: [CHANGELOG](CHANGELOG.md)
+
+## Tested against
+
+- Basic 1.0.8.8
+- Banana 2.0.6.8
+- Potato 3.0.2.8
+
+## Requirements
+
+- [Voicemeeter](https://voicemeeter.com/)
+- Ruby 3.2 or greater
+
+## Installation
+
+### Bundler
+
+```
+bundle add 'voicemeeter'
+bundle install
+```
+
+### Gem
+
+`gem install 'voicemeeter'`
+
+## `Use`
+
+Simplest use case, request a Remote class of a kind, then pass a block to run.
+
+Login and logout are handled for you in this scenario.
+
+#### `main.rb`
+
+```ruby
+require "voicemeeter"
+
+vm = Voicemeeter.remote(:banana)
+
+# vm.run accepts a block
+vm.run do
+  # mute the leftmost strip
+  vm.strip[0].mute = true
+  puts vm.strip[0].mute
+
+  # disable eq for second from left bus
+  vm.bus[1].eq = false
+  puts vm.bus[1].eq
+end
+```
+
+Otherwise you must remember to call `vm.login` `vm.logout` at the start/end of your code.
+
+## `kind_id`
+
+Pass the kind of Voicemeeter as an argument. kind_id may be:
+
+- `:basic`
+- `:banana`
+- `:potato`
+

+# turn VBAN on
+vm.vban.enable
+
+# turn on vban instream 0
+vm.vban.instream[0].on = true
+
+# set bit property for outstream 3 to 24
+vm.vban.outstream[3].bit = 24
+```
+
+### Command
+
+Certain 'special' commands are defined by the API as performing actions rather than setting values. The following methods are available:
+
+- `show` : Bring Voiceemeter GUI to the front
+- `shutdown` : Shuts down the GUI
+- `restart` : Restart the audio engine
+
+The following properties are write only and accept boolean values.
+
+- `showvbanchat`: boolean
+- `lock`: boolean
+
+example:
+
+```ruby
+vm.command.restart
+vm.command.showvbanchat = true
+```
+
+### Device
+
+- `ins` `outs` : Returns the number of input/output devices
+- `input(i)` `output(i)` : Returns a hash of device properties for device[i]
+
+example:
+
+```ruby
+vm.run { (0...vm.device.ins).each { |i| puts vm.device.input(i) } }
+```
+
+### Midi
+
+The following properties are available:
+
+- `channel`: int, returns the midi channel
+- `current`: int, returns the current (or most recently pressed) key
+
+The following methods are available:
+
+- `get(key)`: int, returns most recent velocity value for a key
+
+example:
+
+```ruby
+puts vm.midi.get(12)
+```
+
+get may return nil if no value for requested key in midi cache
+
+### Multiple parameters
+
+- `apply`
+  Set many strip/bus/macrobutton/vban parameters at once, for example:
+
+```ruby
+vm.apply(
+  {
+    strip_0: {
+      mute: true,
+      gain: 3.2,
+      A1: true
+    },
+    bus_3: {
+      gain: -3.2,
+      eq: true
+    },
+    button_39: {
+      stateonly: true
+    },
+    vban_outstream_3: {
+      on: true,
+      bit: 24
+    }
+  }
+)
+```
+
+Or for each class you may do:
+
+```ruby
+vm.strip[0].apply(mute: true, gain: 3.2, A1: true)
+vm.vban.outstream[0].apply(on: true, name: "streamname", bit: 24)
+```
+
+## Config Files
+
+`vm.apply_config(<configname>)`
+
+You may load config files in TOML format.
+Three example configs have been included with the package. Remember to save
+current settings before loading a config. To set one you may do:
+
+```ruby
+require "voicemeeter"
+vm = Voicemeeter.remote(:banana)
+vm.run { vm.apply_config(:example) }
+```
+
+will load a config file at mydir/configs/banana/example.toml for Voicemeeter Banana.
+
+## Events
+
+By default, NO events listened for.
+
+Use keyword args `pdirty`, `mdirty`, `midi`, `ldirty` to initialize event updates.
+
+example:
+
+```ruby
+require 'voicemeeter'
+# Set updates to occur every 50ms
+# Listen for level updates
+vm = Voicemeeter.remote('banana', ratelimit: 0.05, ldirty: true)
+vm.run { ... }
+```
+
+#### `vm.register`|`vm.deregister`
+
+Use the register/deregister methods to register/deregister callbacks and event observers.
+
+example:
+
+```ruby
+# register an app to receive updates
+class App():
+    def initialize(vm)
+        @vm = vm
+        @vm.register(method(:on_pdirty))
+        ...
+
+    def on_pdirty
+        ...
+```
+
+#### `vm.event`
+
+Use the event class to toggle updates as necessary.
+
+The following properties are available:
+
+- `pdirty`: boolean
+- `mdirty`: boolean
+- `midi`: boolean
+- `ldirty`: boolean
+
+example:
+
+```ruby
+vm.event.ldirty = true
+
+vm.event.pdirty = false
+```
+
+Or add, remove an array of events.
+
+The following methods are available:
+
+- `add(events)`
+- `remove(events)`
+- `get`
+
+example:
+
+```ruby
+vm.event.add(%w[pdirty mdirty midi ldirty])
+
+vm.event.remove(%w[pdirty mdirty midi ldirty])
+
+# get a list of currently subscribed
+p vm.event.get
+```
+
+## `Voicemeeter Module`
+
+### Remote class
+
+#### Voicemeeter.remote
+
+You may pass the following optional keyword arguments:
+
+- `sync`: boolean=false, force the getters to wait for dirty parameters to clear. For most cases leave this as false.
+- `ratelimit`: float=0.033, how often to check for updates in ms.
+- `pdirty`: boolean=true, parameter updates
+- `mdirty`: boolean=true, macrobutton updates
+- `midi`: boolean=true, midi updates
+- `ldirty`: boolean=false, level updates
+
+Access to lower level Getters and Setters are provided with these functions:
+
+- `vm.get(param, string=false)`: For getting the value of any parameter. Set string to true if getting a property value expected to return a string.
+- `vm.set(param, value)`: For setting the value of any parameter.
+
+Access to lower level polling functions are provided with these functions:
+
+- `vm.pdirty?`: Returns true iff a parameter has been updated.
+- `vm.mdirty?`: Returns true iff a macrobutton has been updated.
+
+example:
+
+```ruby
+vm.get("Strip[2].Mute")
+vm.set("Strip[4].Label", "stripname")
+vm.set("Strip[0].Gain", -3.6)
+```
+
+### Run tests
+
+To run all tests:
+
+```
+Bundle exec rspec
+```
+
+You can use tags to run only certain tests, for example:
+
+```
+Bundle exec rspec --tag 'higher'
+```
