The Velocity Map Editor; Using The Velocity Map Editor - Kurzweil K2661 Musician's Manual

The Velocity Map Editor

Every attack velocity value generated by your MIDI controller is mapped through the velocity
map assigned on the MIDI-mode RECEIVE page before being passed to the sound engine. If
you're using the Local Keyboard Channel feature, attack velocity values received at the K2661's
MIDI in port go first through the Receive Velocity map, then to the sound engine, then through
the Transmit Velocity map (as selected with the VelocMap parameter on the TRANSMIT page in
MIDI mode), and to the MIDI Out port.
The VelocMap parameter on the TRANSMIT page in MIDI mode affects only the velocity values
the K2661 sends to its MIDI Out port. Normally you'll leave its value set to 1 Linear, especially
when you're 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 you're driving from the K2661. If, for example, you're overdriving a DX7 that you have
slaved to the K2661, try the map 6 Hard2.
The VelocityMap parameter on the RECEIVE page in MIDI mode affects how the K2661
responds to attack velocity values received at its MIDI In port. Normally you'll leave this set to
Linear, as with the VelocMap parameter on the MIDI-mode TRANSMIT page. You might want
to adjust this parameter, for example, to boost or cut the volume response of the K2661 during
playback in Song mode, or when playing a sequence from an external sequencer.
Here's 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 K2661.

The attack velocity value of every note received by the K2661's sound engine is routed through
the map assigned to the VelocityMap parameter (on the RECEIVE 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 we've mentioned above—
VelTouch (Master mode) VelocMap (TRANSMIT page, MIDI mode), or VelocityMap (RECEIVE
page, MIDI mode). Use any data entry method to select the map you want to edit, then press
Edit.
Linear (the default on the TRANSMIT and RECEIVE pages in MIDI mode):
Velocity values are passed through this MIDI map unchanged.
