The Velocity Map Editor

Velocity maps affect the way the K2vx interprets attack velocity values. Velocity maps are
assigned as the values for two different parameters: VelocMap on the XMIT page in MIDI
mode, and VelocityMap on the RECV page in MIDI mode. (They also apply to the VelTouch
parameter in Master mode, but since the VelTouch parameter doesnÕt affect the K2vx, you
shouldnÕt change its default value.) ThereÕs only one list of velocity maps, and all three of these
parameters use this list. Even so, certain maps are intended for use with the VelTouch
parameter in the keyboard version of the K2vx, and others for use with the MIDI mode
parameters. You can think of these as internal maps and MIDI maps. With the K2vx, you
should use only the MIDI maps, and unless you have a problem with the K2vxÕs velocity
response, or that of MIDI devices connected to the K2vxÕs MIDI Out port, you should leave
both the Receive Velocity map and the Transmit Velocity map set to their default values.
Every attack velocity value generated by your MIDI controller is mapped through the velocity
map assigned on the MIDI mode RECV page before being passed to the sound engine. If youÕre
using the Local Keyboard Channel feature, attack velocity values received at the K2vxÕs MIDI
in port go Þrst through the Receive Velocity map, then to the sound engine, then through the
Transmit Velocity map (as selected with the VelocMap parameter on the XMIT page in MIDI
mode), and to the MIDI Out port.
The VelocMap parameter on the XMIT page in MIDI mode affects only the velocity values the
K2vx sends to its MIDI Out port. Normally youÕll leave its value set to 1 Linear, especially
when youÕre recording sequences with a personal computer or hardware sequencer. You might
want to adjust this parameter, however, when you need to change the response of MIDI slaves
that youÕre driving from the K2vx. If, for example, youÕre overdriving a DX7 that you have
slaved to the K2vx, try the map 6 Hard2.
The VelocityMap parameter on the RECV page in MIDI mode affects how the K2vx responds to
attack velocity values received at its MIDI In port. Normally youÕll leave this set to Linear, as
with the VelocMap parameter on the XMIT page. You might want to adjust this parameter, for
example, to boost or cut the volume response of the K2vx during playback in Song mode, or
when playing a sequence from an external sequencer.
HereÕs a list of the velocity maps stored in ROM (the factory presets). Keep in mind, however,
that you should use only the linear MIDI maps; the internal maps are meant for the K2vx.

The attack velocity value of every note received by the K2vxÕs sound engine is routed through
the map assigned to the VelocityMap parameter on the RECV page in MIDI mode). The
velocity maps convert each attack velocity value into a new value, depending on the curve of
the map. By editing velocity maps, you can change the attack velocity value that the maps
calculate.

Using the Velocity Map Editor

To get to the Velocity Map Editor, select any of the parameters weÕve mentioned aboveÑ
VelTouch (Master mode) VelocMap (XMIT page, MIDI mode), or VelocityMap (RECV page,
MIDI mode). Use any data entry method to select the map you want to edit, then press Edit.
Linear (the default on the XMIT and RECV pages in MIDI mode): Velocity values are
passed through this MIDI map unchanged.
