I have tried many methods but still can’t solve it.

nexttick:

 for (let input of inputs) {
            // 绑定事件监听器
            input.onmidimessage = (message) => {
                nextTick(() => {
                    chord.value = getMIDIMessage(message);
                });
            };

        }

forceUpdate:

// 遍历每个 MIDI 输入设备
        for (let input of inputs) {
            input.onmidimessage = (message) => {
                chord.value = getMIDIMessage(message);
                this.$forceUpdate();
            };
        }
