I figure some of it out. Rookie mistake. Sending MIDI Commands using Bank/Program Commands works as long as the Powercab Edit software is not open at same time Helix is sending commands. It must set up a conflict of some sort.

I am still not able to get it to work using MIDI CC Commands -- even with Powercab Edit software closed. I am still interested in ideas on making that function work. If it were designed to only take presets via  Bank/Program Commands why would Line 6 give us all the MIDI CC Values in the user manual?

Thanks Mike.

I am having difficulty getting Powercab Plus to work properly with MIDI commands sent from Helix. I have tried two methods 1) using MIDI CC Commands and 2) using Bank/Program Commands. I have seen the thread and video at topic/34848-attempting-to-use-midi-to-switch-speakers/, while informative, I was not able to solve the problem. Same for topic/34061-helix-lt-in-powercab-via-midi-not-working/.

Hookups:
 L6 Link (for audio) Helix > Powercab 
 MIDI (send commands) Helix > Powercab
 USB (Powercab Edit) Computer > Powercab

Settings:
On Helix (firmware 2.60)  Menu > Global Settings > MIDI/Tempo. Receive MIDI Clock = AUTO. Send MIDI Clock = OFF.
On Powercab (firmware 1.01)  Menu > Global Settings. MIDI PC Receive = ON. MIDI PC Send = OFF.

Regardless of method used:
Helix preset 01A = Flat Mode.
Helix preset 01B = Speaker Mode, Vintage Model.
Helix preset 01C = Speaker Mode, Green Model.

Clearly a MIDI command is being sent, but the results are completely wrong. What is a bit weird about this (probably not a coincidence) is that Helix preset # is somehow synced with the PC preset #. Even when I swap patches around Helix 01A = PC preset 1. I suspect/hope it is something simple. Maybe a rookie mistake in my setup. I just got the Powercab yesterday.

Thanks Mike

Extra Data

The MIDI cable is same one I used to send MIDI changes to my DT Amp, so I am sure it works fine. 

Attempt using Bank/Program Commands:
 MIDI Channel (leave at Base)
 Bank CC00 (leave at Off)
 Bank CC32 (leave at Off)
 Program (set to preset #)
   Helix preset 01A set to PC preset 2
   Helix preset 01B set to PC preset 2
   Helix preset 01C set to PC preset 1

Attempt using MIDI CC Commands:
 Helix Preset 01A
   CC #   Value   Should Be Result
   20      1      Set Speaker Mode
   22      1      Set Green Model
   23      0      Set 57 Dynamic
 Helix Preset 01B
   CC #   Value   Should Be Result
   20      1      Set Speaker Mode
   22      1      Set Green Model
   23      1      Set 409 Dynamic
 Helix Preset 01C
  CC #   Value   Should Be Result
  20      1      Set Speaker Mode
  22      0      Set Vintage Model
  23      2      Set 421 Dynamic

Regarding the pitch shift effects: are any of these clean enough to use for drop-tune/ virtual capo set ups,

I would like to know the answer to this too. I wrote on IdeaScale about a year ago that this is a go / no-go factor for me in deciding to buy the next generation POD. The warble sound on the HD500 is so bad I too have to run a stomp box instead of using the POD pitch shift effect.
