• LFO 1 - Shape & Amount

This screen controls the waveshape and amount of Low Frequency Oscillator 1. The LFO can be used to produce vibrato (when routed to pitch), or tremolo (when routed to volume). The LFO can be routed to control any of the Realtime Modulation destinations (page 123). The five LFO waveshapes are: Triangle, Sine, Square, Sawtooth, and Random. The amount can be varied from -128 to +127. Negative values will produce inverted waveshapes.

• LFO 1 - Rate, Delay & Variation

This screen controls the rate, delay and variation of LFO 1.

LFO Rate

Varies the LFO speed from 0.052 Hz to 25 Hz (000-127).

LFO Delay

Sets the amount of time between hitting a key and the onset of modulation. This can be used to simulate an effect often used by acoustic instrument players, where the vibrato is brought in only after the initial note pitch has been established. The delay range is variable from 0 to 13 seconds (000-127).

LFO Variation

Sets the amount of random variation of an LFO each time a key is pressed. This function is useful for ensemble effects, where each note played has a slightly different modulation rate. The higher the number, the greater the note to note variation in LFO rate. LFO variation is variable from 000-127.

• LFO 2 - Shape & Amount

LFO 2 is functionally identical to LFO 1.

• LFO 2 - Rate, Delay & Variation

LFO 2 is functionally identical to LFO 1.

• Function Generators 1 and 2

The Function Generators are eight segment modulation sources with conditional jumping capabilities and selectable segment shapes. Level and Time parameters are provided for each stage. In addition, the shape of each stage can be individually selected from a palette of 63 shapes. The function generator can be used when you want complex and precise control over a parameter. Through the creative use of its conditional jumps and curves, the function generator can serve as a complex LFO, a complex envelope generator, a mini-sequencer, a random source or all at once if you desire.

Function Generator 1 or 2

The Function Generator contains eight segments, each with a level and time parameter.

The function generator can have up to eight segments, each with a Level and a Time parameter. The level parameter can be either positive or negative. Each segment of the function generator can have a different Shape. There are 63 different shapes consisting of various curves, straight and crooked line segments, random, chaos and delays.

Four of the 63 curves are shown below. By combining the various curve shapes, extremely complex functions can be created. See the Reference Section of this manual for the complete set of function generator curve diagrams.

••• A Conditional Jump always goes to the Beginning of the destination segment.

▼ Remember to turn up the LFO amount when using LFOs as conditionals.

The function generator can be programmed to jump between segments based on certain conditions. Because the decision to jump is based on conditions, these jumps are called Conditional Jumps. For example, the function generator could be programmed to loop only if the key is still being held. In the diagram below, the function generator has been programmed to jump back to segment 3 if the key is held but jump to segment 4 whenever the key is released.

Conditional jumps can be programmed to jump to the destination segment immediately or they can wait until the end of the segment before jumping. The conditional jumps are:

••• Drawing your function generator ideas on paper first will simplify the programming process.

••• Remember that you must assign the function generator to a destination in the Realtime Control screen.

••• The Function Generator Amount can also be modulated by a Realtime Control source.
