There are template parameters (total 20 with user configurable 5) which include following info:

1 Faders and 8 knobs and their corresponding cc# values. For example, ableton uses cc# 21 to 28 for encoder knobs. cc #49 for slider. However cc #7 is more common as master volume in some other DAWs.
Mod wheel (cc #1) can be mapped to your favourite control of choice or you can configure impulse to generate different cc# instead of cc #1.
Current default MIDI channel (Triggers different instruments). (Use MIDI Chan button) You can also configure +N Octave here.
zones configuration to generate different channel / octave ranges for keys partitions.
keyboard velocity (1 to 4)
Aftertouch enable/disable.
You can not configure to generate CC control command messages using keyboard keys to trigger actions using keys (instead of generating Note On/Off Messages). You will have to use other MIDI mapper software for that.
I believe sustain and expression control of this controller can not be configured to generate desired cc# command.

Global Parameters

Following global parameters are system level parameters independent of templates. These are set using "Setup" button in impulse.

The transport controller buttons can be mapped to use cc# or MMC (Midi Machine Control) data.
Trigger Pad Velocity Curve (1 to 3)
Notes should be sent over USB or MIDI or both.
Internal tempo (140 bpm default) for roll/arp.
Global settings can be saved by "SysEx" dump operation to be captured by computer.

Other operations

All the global parameters can be dumped as single sysex message. This can be captured from computer and later be sent to impulse to configure the same ???

Press Shift+MIdI Chan button to send Program Change MIdI msgs.

Factory Reset: Press Shift/+/- Before connecting USB to enter boot menu. Reset is last page.

Available Templates

All templates have following parameters set to the same defaults:
