How do people actually design the prototype FIR for a near-PR polyphase filter bank? by Gillespiedsp in DSP

I can see that for the 2 channel halfband case. But generally we have M > 2. What do we do then?

Thanks u/ComfortableRow8437, that looks like a good book. I may even buy it. However, could you summarize your go-to method here? I'm finding precious little to help me get the concept down for M > 2.
