1.
Expression Pedal Input: This input is to be used with an expression pedal (such as the
M-Audio EX-P, sold separately) for adding expressive changes during performances. The
M-Audio EX-P Expression Pedal uses a 1/4" TRS connector and is set to normally open
(pedal up). The factory default setting of this input is CC#11 Modulation. The expression
pedal input is fully assignable to CC, Aftertouch, and Pitchbend messages.
2.
1/4" FS2/Soft Pedal Input: This input accepts a soft pedal, such as the M-Audio SP-2
pedal which uses a 1/4" TS connection, to soften the notes and modify the tonal quality.
The soft pedal input is fully assignable to MIDI note numbers, Program Change
messages, CC, or MMC messages using the Hammer 88 editor.
3.
Sustain Pedal Input: This input accepts a momentary-contact foot pedal (such as the M-
Audio SP-2, sold separately). When pressed, this pedal which has a 1/4" TS connector,
will sustain the notes you are playing without having to keep your fingers pressed down
on the keys.
Note: The polarity of the sustain and expression pedals is determined by the keyboard
upon startup. When Hammer 88 is powering up, the sustain pedal is assumed to be in the
"up" (Off) position. It is important that the sustain pedal is not pressed during startup,
otherwise the pedal will reverse its operation, and notes will sustain when the pedal is not
pressed.
4.
MIDI Out Port: This standard 5-pin MIDI connector transmits MIDI data to any
compatible device such as a hardware synthesizer, sound module, or drum machine.
5.
USB Port: The USB port delivers power to the keyboard and transmits MIDI data when
connected to a computer.
6.
Power Input: This input accepts an optional third party power supply. A power supply
must be connected when using Hammer 88 in stand-alone mode (when triggering
external hardware synths). Use a USB cable to power Hammer 88 when connecting to a
computer to trigger software synths.
