Assertion playing edit with midi clip set to midi channel 16

Tracktion Engine
1

HI. I’m trying to build little sequencer with tracktion engine, I’m really new to it, and having trouble with playback if midi clip in tracks is set to channel 16, what am I doing wrong? Here’s how I insert midi clip in track:

tracktion_engine::MidiClip::Ptr EngineCore::createMidiClip(int trackNumber)
{
    if (auto track = EngineHelpers::getOrInsertAudioTrackAt (edit, trackNumber))
    {
        auto &dev = track->getOutput();
        
        dev.setOutputByName("Tracktion MIDI Device");
        // Find length of 1 bar
        const tracktion_engine::EditTimeRange editTimeRange (0, edit.tempoSequence.barsBeatsToTime ({ 2, 0.0 }));
        track->insertNewClip(tracktion_engine::TrackItem::Type::midi, "MidiClip", editTimeRange, nullptr);
        if (auto stepClip1 = getClip(trackNumber)){
            auto &s = stepClip1->getSequence();
            stepClip1->setMidiChannel(tracktion_engine::MidiChannel(16));
            s.addNote(48, 0, 2, 25, 0, nullptr);
        }
    }
    return {};
}

I have this assertion in MidiAudioNode.cpp
jassert (channelNumbers.getStart() > 0 && channelNumbers.getEnd() <= 16);
sems like channel number getEnd is setted to 17, but i dont know why.

Thanks for the report, I just pushed a fix for this, will take some time to appear. In the meantime, you can ignore that assert, messages will be sent on the correct channel.

Got it. Thank you!
