• MODULATION WHEEL — Perhaps the most common use of the Mod Wheel is to add
vibrato, but it can also be assigned as a modulator anywhere within the TS-10 voice
architecture to alter the pitch, brightness, volume, effect parameters, and a great many other
aspects of the sound.
Pressure (After-touch)
Another important controller is Pressure. Pressure (often called after-touch) is a modulator that
allows you to change the sound in various ways by pressing down harder on a key or keys after
the initial keystrike. The TS-10 keyboard is capable of generating two types of pressure —
Channel Pressure and Poly-Key™ Pressure.
Like the mod wheel or foot pedal, pressure is a modulator, and can be chosen wherever a
modulator is selected in the Programming section of the TS-10. Pressure can be assigned to alter
the pitch or volume of voices, the filter cutoff frequency, LFO rate or depth, pan location, etc.
There are two types of Pressure:
• Channel Pressure, also called Mono pressure, affects all notes that are playing when you exert
pressure on any of the keys. For example, if you play a three-note chord, pressing down
harder on any of the three notes of the chord will modulate all three notes. This type of
pressure is the more common of the two types.
Most MIDI instruments which currently implement pressure send and receive only channel
pressure. If you are playing such an instrument from the TS-10, you should set the TS-10 to
send channel pressure. (Note that some devices, including all ENSONIQ products respond to
both types of pressure.)
• Poly-Key Pressure, also referred to as polyphonic pressure, is a more sophisticated and
expressive type of pressure. Poly-Key pressure affects each key independently. For example,
if you play a three-note chord, pressing down harder on any of the three notes of the chord
will modulate only that note. The other two notes will remain unaffected.
Each preset or sequencer track can be programmed to generate Poly-Key pressure, channel
pressure or none at all. If you wish to change the pressure type for a given track, you can do
so on the second sub-page of the Performance Options page in the Track Parameters section of
the TS-10.
Note that Poly-Key pressure generates a tremendous amount of data, and will consume
sequencer memory much faster than other types of events, such as notes and program changes.
You should turn pressure off when sequencing instruments which do not respond to pressure,
such as piano and drum sounds.
