The easiest way to get your H9 programs changes synced to your KPA, is the way I mentioned above. Each rig in every performance can send program change messages to two different midi devices / midi channels. Your KPA can also send midi clock information to other midi devices, to keep them in tempo sync. Both of these features are disabled in the KPA by default. To get this working, you have to enable them first.
IMPORTANT - You must have a midi cable going from the "Midi Out" port of your KPA, going to the "Midi In" port of your H9 or other device for this to work. If you want to add a 2nd device, grab another midi cable and go from the "Midi Thru" (not midi out) of the second device to the "Midi In" of the third device, then setup the second device channel in the KPA and put it on a different midi channel than the first device.
1. Setup the two midi devices/midi channels in your KPA.
In KPA system menu on page 13, you have two devices which you can name and assign different midi channels. You only need to use one of them for the H9. The other could be used for another midi pedal if you have one. I use "A" for my H9. You can assign it to any of the 16 midi channels. Just make sure to put your H9 on the same midi channel via the Pedal/Midi Settings page of the H9 Control software. I only use the one midi pedal, so I keep my H9 set to Omni.
2. Make sure your H9 is on the same midi channel that you told your KPA it was on it step 1 above.
If the midi device that you are sending to is not on the same midi channel, then it will not receive the program changes (or any other midi information) from your KPA. Luckily, your H9 is assigned to OMNI midi mode from the factory. This is a special midi channel which receives midi information on all of the 16 available midi channels at the same time. If you only plan on using the H9 with your KPA, then you are fine leaving it in OMNI mode. If you decide later to add a second midi device, then you'll want to turn off OMNI mode in the H9, and assign it to a specific midi channel, so your H9 doesn't also receive midi changes being sent to the 2nd device.
3. Turn on the "Send Midi Clock" in the KPA. This will keep your H9's tempo locked with the KPA, for rigs that have their tempo enabled.
On page 14 of the KPA system menu, check the Send Midi Clock box. This will send midi clock signal to your H9, syncing it with the KPA's tempo. You also have to configure the H9 to Receive the midi clock from the KPA, via the Pedal/Midi Settings/Midi Clock page of H9 Control. Change "Enable Midi Clock Input" to yes.
4. Go into each rig in each performance and tell it what H9 program you want to use with that rig.
In any performance, click the edit button then edit settings, then midi settings, if I remember correctly. Then use the first knob to select your H9 Device that you setup earlier. Use the 2nd knob to choose any of the H9's 127 programs. Don't forget to store your performance afterwards. Repeat this for every rig in every performance, if you want.
FYI. The KPA only sends program changes when a new rig is selected. To see if you setup and stored the right program change, switch to a different rig, then back to the rig you just saved. When you switch back, the KPA should send the midi program change to your H9.
