The Resonant Chord effects use impulsive energy at the inputs to excite six
resonant voices (notes). The level, pitch, duration, and high-frequency cutoff of
the overtones for each voice are separately controllable. Each voice can be
panned independently. The voices resonate to some degree with any input, but
the most effective excitation contains all frequencies, like percussion. Other
instruments may give a quality of tonal ambience in which certain notes rise
ethereally from the background. The output of the resonator is then fed into a
stereo plate reverb effect.

The two algorithms differ in the way pitches are assigned to the resonators. In
Res1>Plate, pitches are assigned to the six voices chromatically, in a roundrobin.
If, for example, MIDI note numbers are used to assign pitch, the
resonators will constantly be re-tuned to the pitches of the last six MIDI notes
received. (This can produce an effect similar to playing a piano with the sustain
pedal depressed.) In Res2>Plate, pitches are assigned to the six resonators
diatonically — harmonized with the key, scale, and root of your choice. If MIDI
note numbers are used to assign pitch, the resonators will constantly be re-tuned
to harmonize with the incoming notes.

These algorithms can address up to 4 Meg of delay memory (with optional
SIMMs added to the PCM 80), providing 38 seconds of stereo delay.

This effect features six separately adjustable voices, each with its own level
control, delay time, low and high frequency filters, feedback and pan controls.
The multi-band effect is in parallel with a Chamber effect, providing independent
stereo effects. Note that the Diffusion parameter (Rvb Design 2.1) is shared by
both the multi-band and reverb effects. Note also that, in this particular algorithm,
the diffuser is within the feedback paths of the multi-band voices. This allows you
to create filtered echoes that grow more diffuse with each repeat, or to create
effects with filtered echoes passing through the reverberator.

This algorithm can address up to 4 Meg of delay memory (with optional SIMMs
added to the PCM 80), providing 42 seconds of stereo delay.

The PCM 80 offers an extensive set of informative display messages which can Info
be activated from the front panel.

The front panel switches perform various functions when pressed. Most of these
functions are activated on release of the button. If you want to know more about
the function of a particular button (without actually executing any action) press
and hold the button down. While you are holding down the button, an explanatory
message will appear on the display. The activation of an Info message overrides
the normal function of the button, so that no action is taken on release.
