NdefGui fails with a NamedControl with an array of buffers

hey,

i get an error message “rate” not understood when using a NamedControl with an array of buffers and NdefGui, is this a bug?

s.boot;

b = Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav");
~arrayOfBufs = [b, b, b];

(
Ndef(\test, {
	var arrayOfBufs = \arrayOfBufs.kr(Array.fill(3, 1));
	PlayBuf.ar(1, arrayOfBufs[0], loop:1) * 0.2 !2}).set(\arrayOfBufs, ~arrayOfBufs).play;
)

Ndef(\test).gui;  //ERROR: Message 'rate' not understood.

i have seen a similiar issue has been fixed already:

bug

Calling .gui on a Ndef with a Buffer instance as an argument produces an error. … This affects NdefMixer as well if you happen to click the 'ed' button. Buffer does not implement rate. Bus and other classes in question do. ## Environment * SuperCollider version: 3.12.2 * Operating system: macOS ## Steps to reproduce ```supercollider s.boot; b= Buffer.read(s, Platform.resourceDir +/+ "sounds/a11wlk01.wav"); Ndef(\test, {|buf| PlayBuf.ar(1, buf, loop:1)*0.2!2}).set(\buf, b).play; Ndef(\test).gui; //ERROR: Message 'rate' not understood. ``` ## Expected vs. actual behavior It should not throw an error, but instead display the buffer's bufnum. ## Proposal for fixing ```supercollider --- a/SCClassLibrary/JITLib/ProxySpace/NodeMap.sc +++ b/SCClassLibrary/JITLib/ProxySpace/NodeMap.sc @@ -132,7 +132,9 @@ ProxyNodeMap : NodeMap { controlNames { var res = Array.new; this.keysValuesDo { |key, value| - var rate = if(value.rate == \audio) { \audio } { \control }; + var rate = if(value.respondsTo(\rate) and:{ + value.rate == \audio + }) { \audio } { \control }; res = res.add(ControlName(key, nil, rate, value)) }; ^res ```

What version of SC are you on? I think this has been fixed if you update to the latest version

hey, im on Windows with SuperCollider 3.13.0
With just one buffer like in the example its working for me but not with a NamedControl and an array of buffers.

its a bug.
i have saved this as an extension, then it works:

// define rate for all objects that don't define it themselves
+Object {
  rate { ^\noncontrol }
}

will open an issue on github.
