Assigning Kemper Performances with Helix snapshots

Recommended Posts

Hi,

 

I have a Kemper and Helix Effects.

 

I've been trying in vain for the last 2 weeks to assign performances using either Instants or Footswitches to assign Kemper performances slots to Snapshots.

 

I have NO midi experience.

 

Can someone please just tell me what to enter into either Bank PC or Midi CC, then I can amend for other performance slots.

 

Whatever I do isn't working and I'm getting more and more frustrated!

 

Please help!

First, I don't have a KPA. But I'm pretty good at MIDI and manuals.

 

Bottom line: As long as you can make due with 125 presets, you're good with Bank 1 (MSB=0:0, LSB=CC#32 Value=0, PC#s 0-124). That's 25 Performances with 5 slots each.

If you need more........

 

Here's the details, hopefully more clear than the manual.

 

Step 1 - MIDI Channel

KPA default is OMNI. That means it receives on ALL Channel.
Helix default is Channel 1

If the KPA is the only MIDI device you're using, you shoiuld be OK with the defaults. 

If there are more than one MIDI devices downstream from the Helix, you probably want to set them to different Channels, and specify the Channel/device that the MIDI command your sending is intended for when you set it up in Command Center.

 

Step 2 - KPA Performance and Slot

Bank # - MSB always = 0
               LSB always = CC#32. The Value = (Bank# -1). Bank 1=0; Bank 2=1; Bank 5=4.

 

Performance/Slot#

This is selected using Program Change Numbers (PC#). Within a given Bank you have 25 Performances with 5 Slots (+3 - see below). There are 128 possible MIDI PC#s, 000-127.

 

The formula to find the PC# for a specific Performance and Slot is (#Performance * 5) - 5 + (#Slot - 1).

 

Bank 1 Performance #1 Slot #1 would be:

MSB=0 LSB=CC#32 Value 0

1*5=5
5-5=0
0+(1-1)=0

Performance #1 Slot 1 = PC#000. (Helix uses 0-127).

 

Performance #25 Slot 5 would be:

25*5=125
125-5=120
120+(5-1)=124

Performance #25 Slot 5 = PC#124

 

Here's where it gets to be fun.

Performance #26 Slot 1 would be:

26*5=130
130-5=125
125+(1-1)=126

Performance #26 Slot 1 = PC#125
Performance #26 Slot 2 = PC#126
Performance #26 Slot 3 = PC#127

 

BUT THEN

Performance #26 Slot #4 would be:

26*5=130
130-5=125
125+(4-1)=128 ERROR!!!!!

 

Performance #26 Slot #4 is in Bank 2! NEW FORMULA - (#Performance - 26) * 5 + (#Slot - 4)

To get Performance #26 Slot #4 you have to start over by sending LSB #32 with a Value of 1 to select Bank 2.

THEN:

(26-26)*5=0
0+(4-4)=0

Performance #26 Slot 4 = LSB #32 Value 1 PC# 0.

 

PITA? You betcha!

Only piece of MIDI equipment I've ever seen that requires a calculator (or a pre-printed spreadsheet?)to figure out how to load presets!

 

Bottom line: As long as you can make due with 125 presets, you're good with Bank 1 (LSB=CC#32 Value=0 PC#s 0-124). That's 25 Performances with 5 slots each.

If you need more, HAVE FUN!

 

WARNING!!! By all means, check my math. I've only had one cup of coffee, and this is giving me a headache!
