keymaps. For each oscillator, its coarse pitch parameter is named by an abbreviation of the
oscillator name followed by "Pch." For example, the coarse pitch parameter for a saw wave
oscillator will be called Saw Pch. On the DSPCTL sub page for any oscillator Pch. parameter,
you can adjust fine pitch by cents and Hertz, as well as KeyTrk and VelTrk settings for pitch.
Note: Be sure to differentiate between the different pitch parameters, each used either only for keymaps or
only for KVA oscillators. The Pitch parameter on the top left of the DSPCTL and DSPMOD pages always
appears in VAST programs but only affects the pitch of keymaps. If a KVA oscillator is being used, this
Pitch parameter will have no affect on the layer's pitch, in which case the oscillator Pch. parameter
described above must be used to control the pitch of the oscillator.
Setting KVA Oscillator Type
The PC3LE comes with 22 different KVA oscillators. There are 11 high quality anti‐aliased
oscillators (free of digital artifacts,) and 11 oscillators that exhibit some aliasing (digital artifacts)
in the higher octaves. The anti‐aliased oscillators use up more DSP resources than the ones with
aliasing, but the improvement in sound quality is quite noticeable. We strongly recommend
using the anti‐aliased oscillators for most applications.
The tables below list KVA oscillators by type and function block size. Before setting an oscillator,
you must choose an algorithm which includes a block that matches the block size for the
oscillator that you wish to use. See The Algorithm (ALG) Page on page 6‐27 and Algorithm
Basics on page 6‐28 for more on selecting algorithms. Once you have picked an algorithm with
the desired block size, highlight the block and use the alpha wheel to scroll through the
available functions until you find the desired oscillator.
The SYNC SQUARE oscillator is an 8 block oscillator that requires the use of two layers (4
blocks each) and the Alt Input feature of cascade mode. See below for details on setting up the
Sync Square oscillator.
Note: If you put more than one oscillator in an algorithm, you will only hear the output of the last
oscillator in the algorithm, unless an algorithm is used to route the earlier oscillator around the last
oscillator and into a MIX function block, or if the last oscillator processes its audio input.
