Can't open in Ableton on Mac

[helixbass]

Hi, I am trying to get a MIDI effect plugin using nih_plug working and came across this plugin as a nice example. I found that my plugin and the version of this plugin that I downloaded both failed to open in Ableton (on Mac). It appears that the issue is what is described here, when I commented out this in my plugin I was able to load it in Ableton:

const DEFAULT_INPUT_CHANNELS: u32 = 0;
const DEFAULT_OUTPUT_CHANNELS: u32 = 0;

(I guess those are specifying that this is a "non-audio" plugin and Ableton doesn't want to load non-audio VST3 plugins?)

So I don't know what a good solution would be to allow (new) released versions of this plugin to be able to run on Ableton since I think there are downsides to that hacky commenting-out solution (eg Ableton then seemed to show some audio-related GUI in its panel for the plugin whereas I don't think it typically does that for non-audio plugins)?

Fwiw I've successfully run VST2 MIDI effect (non-audio) plugins in Ableton (that I created using JUCE) but I guess this is Ableton + VST3-specific

Thank you for the report. Unfortunately, I do not own Ableton so I can't really debug this issue. I might try out a trial of Ableton and see if I can fix it somehow but I will need to find the time for that. If you have any further suggestions you are more than welcome to open a pull request or discuss the issue further here!
