 ## Implementation Notes
 
-1. The VBAN TEXT subprotocol defines two packet structures [ident:0][ident-0] and [ident:1][ident-1]. Neither of them contain the data for Bus EQ parameters.
+1. The VBAN RT SERVICE subprotocol defines two packet structures [ident:0][ident-0] and [ident:1][ident-1]. Neither of them contain the data for Bus EQ parameters.
-2. Packet structure with [ident:1][ident-1] is emitted by the VBAN server only on pdirty events. This means we do not receive the initial state of those parameters on initial subscription. Therefore any commands which are intended to fetch the value of parameters defined in packet [ident:1][ident-1] will not work in this CLI.
+2. Packet structure with [ident:1][ident-1] is emitted by the VBAN server only on pdirty events. This means we do not receive the current state of those parameters on initial subscription. Therefore any commands which are intended to fetch the value of parameters defined in packet [ident:1][ident-1] will not work in this CLI.
 3. Packet structure with [ident:1][ident-1] defines parameteric EQ data only for the [first channel][ident-1-peq].
+4. There doesn't appear to be any way to retrieve the current recorder status, ie, recording, playing, stopped etc. I don't see the data available in either packet structures [ident:0][ident-0] or [ident:1][ident-1].

 I've made the effort to set up the basic skeletal structure of the CLI as well as demonstrate how to combine subcommand groups with subcommand groups so more can be implemented, it just needs doing. There may be restrictions on some things however, for example, retrieving values is only possible for parameters [defined in the protocol](https://github.com/onyx-and-iris/Voicemeeter-SDK/blob/3be2c1c36563afbd6df3da8436406c77d2cc1f10/VoicemeeterRemote.h#L787). Setting parameters can be done for anything possible by a string request.
