Sum Node Lag 0 Lag Lag 0 sum Audity 2000 Operations Manual 77 Programming Basics Modulation Processors Using the Modulation Processors Modulation processors are inserted into a modulation routing as shown in the following diagram. The modular analog synthesizers of yesteryear were incredibly flexible, partly because processing devices could be connected in any order. Modulation processors are designed according to this modular concept. They can be linked and used in a wide variety of ways limited only by your imagination. Consider the following example: Velocity ~ Cord Switch Cord Switch On when Velocity > 0 Switch value is Scaled by Cord Amount Pitch The patch illustrated above is programmed by setting the PatchCord screens as shown below. PATCHCORD Vel+- -> Switch L1 #01 +100 PATCHCORD Switch -> Pitch L1 #02 +022 This particular modulation shifts the overall pitch up a fifth when the key velocity exceeds 64. Velocities below 64 play at normal pitch. Velocities of 64 and above are raised a perfect fifth. The Velocity "~" source scales the played velocity around zero. In other words, low velocities (below 64) will have negative values and high velocities (64 and above) will be positive. The Switch module only outputs a "1" if the input value is greater than zero. This digital "1" value can be scaled through the attenuator on the PatchCord to raise or lower the pitch by any amount. In this case, a scaling value of +22 raises the pitch by a perfect fifth. The amount of the PatchCord on the input to the switch is unimportant because ANY velocity value equal or greater than 64 will flip the switch. If the input PatchCord amount were a negative value however, the action of the velocity would be reversed and velocities less than 64 would raise the pitch and velocities equal or greater than 64 would play the original pitch. 78 E-mu Systems, Inc. Programming Basics Modulation Processors But what if you want the velocity switch point to be something other than 64?Thanks to modulation processors, it can be done. Here's how. Velocity ~ Cord Switch 21 Cord Switch On when Velocity > 0 Switch value is Scaled by Cord Amount Pitch DC Cord Connect the DC level to the input of the switch along with the velocity value. Note that more than one modulation source can be applied to the input of a processor. DC offset adds a fixed value based on the PatchCord Amount setting. If applied to the switch along with the velocity, it changes the velocity value required to trip the switch. By setting the DC amount to a negative amount, higher velocity values are required to trip the switch. Setting the DC value to a positive value would bring the velocity switch point down. The PatchCord screens for this patch are shown below. PATCHCORD Vel+- -> Switch L1 #01 +100 PATCHCORD DC -> Switch L1 #02 -021 PATCHCORD Switch -> Pitch L1 #03 +022 More Examples To derive a smooth random function you could route the Pink Noise generator through one of the Lag Processors.
