# Sending incremental/decremental PC numbers or CC Values

It is possible to send incremental or decremental (by 1) PC messages with the MIDI controllers. This feature is further enhanced in Firmware `v3.8`.
 
# Firmware v3.8.x onwards
In Firmware v3.8.x onwards, we added the `Scroll Counter` settings in the `Controller Setting`. Here, you can edit the `start`, `minimum` and `maximum` values for each of your 16 counters. The start value is the value that the counter will be at when the device powers up.

|| Do note that the Counters are labelled using the hexadecimal notation 0 - F, which in decimal terms is 1 - 16.

### Example
After programming your `Scroll Counter` settings, you need to program your Preset to send the CC or PC message using values from the `Counters`. I’ll be using the `PC Number Scroll` message type for this example. You can send incremental/decremental CC values as well using the `CC Value Scroll` message type. The concept is the same.

For the `Scroll Type` parameter, there are a few options to choose from
* `Send only` sends the PC message without changing the counter value
* `Increase by 1 and send` will increase the counter value by 1 and then send the PC message
* `Decrease by 1 and send` will decrease the counter value by 1 and then send the PC message
* `Update only` will just update the counter value
* `Reset only` will just reset the counter value to the default value

If I want to send an incremental PC number each time I engage the preset, I’ll choose the `Increase by 1 and send` option.

The next parameter `PC Number as value in Counter` allows you to select the Counter that you want to use (from Counter `0 - F`). I’ll choose `Counter 0` for this. I’ll also set my MIDI Channel to `1`.

After saving these settings, each time I engage the Preset, the PC number sent will increase by 1, as seen on the MIDI Monitor.

# Scrolling through multiple PC messages with the same PC number
The setting below will send an incremental PC message on both Channel `1` and `2`. Both PC messages will use the value in `Counter 0`.

If I check the MIDI Monitor, the following messages will be sent out each time the Preset is engaged.

# Firmware v3.7
In Firmware v3.7, using the `PC Scroll Up` or `PC Scroll Down` message type will allow you to send incremental or decremental messages respectively. 

The setting below will 
* Use Slot (or Counter) 1 with a lower limit of `0` and upper limit of `127`. It will also increment the number each time the Preset is engaged
