Appendix A - Touch Surface LFO S&H: In Use
The Touch Surface LFO S&H function is a recent addition to the Voyager operating system, adding Sample &
Hold capabilities to the Touch Surface. To understand what this function does, try this simple example:
1. Initialize a preset using EDIT Mode Menu 1.3 (Init Parameters).
2. From EDIT Mode Menu 5.1 (T.S. Destinations), select the TSX menu and configure the
parameters as follows:
Destination: Oscillator 1 Octave
MIDI CNTL No: OFF
Direction: Normal
Amount: 100%
TSX LFO S&H: ON
3. Set the LFO RATE control to about 10 ‘o clock.
4. Touch the Touch Surface and move your finger slowly across the surface on the X axis. You
will hear the pitch of Oscillator 1 change instantaneously, not smoothly, at twice the rate of
the LFO.
This illustrates the basic concept of the TS LFO S&H function. When the TS LFO S&H is switched ON for
TSX, TSY or TSA, it effects all of the assignable control parameters for that axis, including the Destination,
MIDI Control Number (1-127), Direction (Normal or Inverted) and Amount (OFF, 25%, 50% and 100%).
The TS LFO S&H output also appears on the Touch Surface X, Y, A and GATE outputs of the Modular Patch
Panel.
Since the TS LFO S&H function is controlled by the LFO, it means that all of the LFO SYNC control settings
(MIDI, KY, ENV GATE) apply to the Touch Surface LFO S&H function as well.
To download examples of Presets programmed to use the TS LFO S&H function, go to the Moog Music
web site (www.moogmusic.com).
1. By sweeping your finger across the Touch Surface in time with the Sample and Hold rate,
you can create precise rhythmic modulations & effects.
2. When an external Control Voltage (CV) signal is applied to the S&H Gate Input on the Voyager
back panel, it overrides the LFO as the S&H clock. This configuration allows you to clock the
TS S&H independently of the LFO to create non-synchronous S&H/modulation effects.
