However the night before typing this I spent a massive amount of time chasing the vocoder set up in SEQ MODE at least four hours trying to get it to work.
So here it goes...
1. Copy from Program O-126 Vocoder Mic Input -1
2. I swear I kept setting the FX Control to 1
3. Set to FX Control 1 in Audio Track Tab
4. Set to Rec Bus on Audio Tab to 1
5. test mic while playing a chord
6. I get the sound from the chord but the voice is not going thru the effect

I went back and forth with this for about up to a total of four hours with even referring to the manual but the audio signal would not route through as hoped until I chose from IN-Track Sampling for which I do not wish to do. However when I did choose this selection the signals now [seemed] to route as ex-pected.
so would this not work the same as in SEQ Mode ?
Unless we have changed something then just copying from Program and selecting how the Effect Setup / Routing would copy in-to the SEQ Insert effect section ?
2. For the Audio Input, set the FX Control Bus (0โ8c) to FX Control 1.
This sends the audio input to FX Control Bus 1.
3. In IFX1: Vocoder, set the Modulator Source to FX Control 1.
