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
