Simultaneously pressing Up and Tempo will toggle these two display options Note The PCM 80 allows six LFO shapes sine cosine sawtooth triangle square and pulse to be selected as patch Sources as well as the LFO itself All of these are generated by a single LFO and are controlled by the single Rate control When LFO is selected as a patch Source the output will be the Shape selected here The amplitude of the LFO output is controlled by Depth Both Shape and Depth are available as patch Destinations and can be controlled externally Shape Pulse Width Depth and Rate are all available as patch Destination parameters and can be controlled externally See Patching in Chapter 2 Modulation Shape Rate and Depth can be controlled by a patch 3 25 The Algorithms and Their Parameters Mod AR Env This envelope generator s output when turned on will go from 0 to127 How quickly it goes from 0 to 127 is determined by the setting of Attack 0 10 seconds Once the envelope generator has reached 127 it remains there as long as it is turned on When it is turned off it goes from 127 to 0 at the rate determined by Release 0 to 10 seconds T Src allows you to select a Source to turn the envelope generator on and off T Lvl allows you to select a specific threshold value which the T Src must reach to turn the envelope generator on The Mode parameter allows you to determine the behavior of the envelope controller in relation
8. The Parameters PCM 80 parameters are organized into labeled rows within each edit matrix Although there are similarities among all matrixes such as having a row of Controls first and Modulation and Patching rows last some of the parameters within each row and some entire rows are unique to specific algorithms This section contains descriptions for all PCM 80 parameters organized alphabetically by row label as follows Chorus Controls Delay Time Feedback Cross Feedback Filters Glide FX Levels Modulation Panning Patching Pitch Resonance Rvb Design Rvb Time Individual parameter descriptions within each row are presented as far as possible in the order in which they appear from left to right in the edit matrix In the Chorus Rvb algorithm Row 5 provides parameters which provide rate and depth controls for each of the six chorus voices as well as master rate and depth controls MstDepth and MstRate Two Master Chorus parameters in the first row position allow Chorus Depth and Rate for all voices to be simultaneously scaled Each control has a range of 0 200 Press Load to toggle between MstDepth and MstRate Voices Depth and Rate Each voice position has Depth and Rate controls to set the time range delay and rate of change across that time range pitch of the chorusing effect Press Load to toggle between them Depth provides settings of 0 500ms in single millisecond increments Rate parameter can be set to 0

11. In this preset and in every preset we have designed the Soft Row by assigning the parameters in numerical order so that parameters from the Controls row are assigned in order to the first locations followed by assignments from the Rvb Time row and so on As Soft Row parameters are also labeled with the name of the row from which they were taken this makes it relatively easy to find the source parameter for any Soft Row assignment The Soft Row assigned to an effect appears above Row 0 in the full Edit matrix We have highlighted those parameters in the Edit matrix which have been assigned to the Soft Row of P 0 0 Prime Blue for example FX Width and Mod Sw 1 2 29 Basic Operation When you release the Edit button the display will change to the Soft Row Assignment display shown below The Edit button LED will begin flashing and will continue to flash as long as you are in Soft Row Assign Here we show the first Soft Row parameter in our example the actual Soft Row parameter selected will correspond to whichever one was displayed when you pressed and held Edit 3 Turn ADJUST to scroll through all of the available parameters in the Edit matrix row by row in numerical order The entry available can also be selected to indicate that no assignment has been made at that position 4 Turn SELECT to display another Soft Row position 0 9 for assignment For each position you can choose any effect parameter including one

25. Mod Latch The latch is a very flexible modulation source It can be used to do such things as derive a switch from a continuous return to zero source like MIDI After Touch It can turn a momentary on off footswitch into a latching footswitch push on push off and it can divide the switching rates of sources in half or thirds The latch has three parameters Src High and Low Any patch source can be the Src See Source listing under Patching High and Low are threshold values The latch works as follows Modulation cont d There is no output from the latch until the Src value falls within the range defined by the settings of High and Low While the source value is between these thresholds the output of the latch is the same value as the source When the source value reaches or passes either threshold the output of the latch holds at the limit value until the source value passes through the threshold twice The latch can be set to hold at either the low threshold the high threshold or both Setting Low to 0 disables latching at the low threshold Setting High to 127 disables latching at the high threshold See preset P0 3 0 FSw2 Rotary as an example 3 27 The Algorithms and Their Parameters Mod Sw 1 and Mod Sw 2 These are identical time switches Each has five parameters Rate P Width Mode T Lvl and T Src Rate sets the speed at which the switch cycles It can be set in time values such as 1 5 Hz or tempo val

This algorithm emulates a real concert hall The reverberation is very clean and designed to remain behind the direct sound adding ambience but leaving the source unchanged This effect has a relatively low initial echo density which builds up gradually over time Concert Hall Lexicon 3 4 PCM 80 User Guide The Plate algorithm mimics the sound of metal plates with high initial diffusion and a relatively bright sound This makes them a good choice for enhancing any type of percussion Plate 3 5 The Algorithms and Their Parameters The Chamber algorithm produces an even relatively dimensionless reverbera tion with little change in color as the sound decays The initial diffusion is similar to the Concert Hall algorithm but the sense of space and size is much less obvious This characteristic along with the low color in the decay tail makes Chamber useful on a wide range of material It is especially useful on spoken voice giving a noticeable increase in loudness with very low color Chamber Lexicon 3 6 PCM 80 User Guide Inverse The Inverse algorithm allows you to vary the slope of the initial portion of the reverb envelope The slope can decay remain level or rise over a variable time interval When the time interval is up the reverberation cuts off abruptly The resulting effect is similar to a gate but is not at all dependent on the level or complexity of the input signal Slopes are adjustable over a ne
