How to - 15 Use Multiple SoftSynths on a Track

Maybe you already do it this way.

It's easy to handle the audio of multiple drum instruments separately.
The trick is to send auxiliary sends to MIDI buses instead of auxiliary audio.

Each instrument bus starts with a MIDI filter that only lets the instrument's note pass through.

This allows you to create a stable flow regardless of the plugin you use. It doesn't require multi-channel plugins, but it will work with them too.

It's also possible to use different plugins for each instrument.

Therefore, it's not only simpler than multi-channel audio, but also more versatile.
