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 congure 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 nger 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 nger 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 conguration allows you to clock the
 TS S&H independently of the LFO to create non-synchronous S&H/modulation effects.
