Play your mono synth as a poly synth
The ensemble is an effect that you can use to play a(n external) mono synth as a poly synth. Using pitch shifters, the incoming voice of the mono synth is multiplied (it can also be used to create backing vocals on the fly). It is made with blocks. It contains a modified Note In block for multiple note output, modified VFFT pitch shifter from Jan Brähler (https://www.native-instruments.com/en/reaktor-community/reaktor-user-library/entry/show/10267/), modified Bento Box envelope (four envelopes in one) and modified bento box mixer (four mod inputs instead of two). I have made a short youtube video here: https://youtu.be/z0oCMD1Ldck.
It is still a work in progress and can definitely use some improvements, but it does work.
