Hello,
If you use H9 Control and go to Pedal Settings > Program Change Receive Map, you can see exactly how this is configured. Sometimes the offset can be caused by your MIDI controller ignoring the PC 0 command, for example if you send PC 0 that will load Preset 1, PC 1 will load Preset 2, etc. You can configure the PC map on the H9 to however you would like this to work, and you can use a MIDI monitor app to see which PC messages your controller is sending.
Yes, there are always 10 knobs for the 10 algorithms parameters and you will map your MIDI CCs to those knobs. Yes, that is the correct order for the knobs.
Let me know if you have any other questions or issues.
