The way to get more available MIDI channels in one sequence is to add the ability to address more than one MIDI synth at a time.

Synth "A" can support 16 MIDI channels.

Synth "B" can support 16 separate MIDI channels also.

That yields 32 available channels of separate voices.

The ability to add more than two synths at the same time can expand even further.

etc.

Of course, the level of complexity rises, and the level of complication for the user goes up exponentially by comparison.

This is also likely a far easier thing to accomplish with Hardware oriented MIDI synth/samplers than trying to tax the CPU host with software solutions.
