1 6 dSP coNFIGURA tIoNS The PCM96 Surround processor can be divided in up to four virtual machines, each of which can r un its own algorithm. This lets you route sig- nals from each input through a variety of algorithm combinations . The PCM96 Surround can use up to six physical inputs and six physical outputs at a time; configurations for the phys[...]

17 When dealing with true surround source material, the choice of configu- ration is simple--choose the 4-in or 5-in version. The algorithms are all designed to treat the inputs uniquely . If the algorithm is a reverberator or room, then each input will propagate into the space from the direction of its virtual source. If the algorithm is a delay o[...]

37 the ALGoRIthMS chAMbeR (SURRoUNd, SteReo ANd MoNo) Chamber is a complex miniature-space effect resembling an echo chamber at its smaller settings and, at its larger ones, a small performance space with a more rapid build-up of reflection density than a hall. Reverberant tails are randomized. RANdoM deLA y (SURRoUNd, SteReo ANd MoNo) Random Delay[...]

38 Random Delays are similar to Simple Delays, but are especially useful for: • M ultitap T ape Loops F eedb ack can be used to recir culate delay s. Approp riate use of hi ghpass and lowp ass filters emula tes the ban dpass effect s of multi- generati onal tape loops (hiss not included). F eedback diffusion allows emulation of azimuth misalignme[...]

39 RANdoM hALL (SURRoUNd, SteReo ANd MoNo) Random Hall is a hall effect with gradual build-up, well suited to complex sounds like orchestral music. Its reverberators change over time in controlled random ways to avoid the buildup of tinny , grainy , metallic, or other color- ations. The modulation can be noticeable and is often a desirable effect. [...]

40 ReSoNANt choRdS (SURRoUNd, SteReo ANd MoNo) The Resonant Chord algorithm uses 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[...]

41 round-robin. F or example, if MIDI note numbers are used to assign pitch, the resonators will constantly be re-tuned to the pitches of the last six MIDI notes receiv ed. (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 [...]

42 sets themselves may be loaded into either type of machine, with the appro- priate number of voices appearing.

43 the P ARAMeteRS The PCM 96 contains hundreds of presets, covering just about every pos- sible need. But you can refine and customize any preset by adjusting its parameters . P arameters are the building blocks within each preset that deter- mine how it sounds and behaves. Each algorithm contains a set of parameters, and a variety of those param-[...]

44 Category (Room) This parameter lets you select a specific category from which a room response may be chosen. Changes here have a direct effect on the P attern Selector parameter . Chorus Depth (Concert Hall) This parameter controls the amount of randomization of the chorus tap. Higher values are generally preferr ed in order to minimize reverb c[...]

45 Feedback This controls the amount of echo output that is fed back to the input of the echo buffer . The actual feedback level is modified by the Master Echo F eedback param- eter , if present. The master value is a percentage (0-100%) that is applied to the Echo F eedback level. Feedback Diffusion F eedback Diffusion is similar to Input Diffusio[...]

46 This tells the shifter the lowest frequency that it may be required to shift. As a general rule of thumb, this should be set in the higher part of the range in order to preserve detail in the shifted material. It should be low ered if arti- facts appear in the low frequencies. Master Echo Delay Controls all echo voices in the algorithm. Each ech[...]

47 there may be one or more reflection delays for each input channel. Some of the delays may mix their outputs to the same channel (left to left) and some may go cross-channel (left to right). Reflection Gain (Level) Each Reflection Delay voice also has a gain value. This gain is controlled by the Reflection Gain parameter . Resonance This paramete[...]

48 Reverb Spin (Spin) This is usually simply called spin. It controls the speed of the reverb random- izer . S pin is also connected with the Reverb W ander parameter Reverb T ime Hi Cut This parameter , also known as Hicut or R THC is a low-pass filter in the recirculating part of the reverb. It represents a frequency abo ve which the tail dies aw[...]

49 Tip : Shape will not have this effect if spread is at its minimum value. B ut even then, it can make a difference. In this case, it affects reverb tim - bre and densit y . High er values of shape will be both darker and denser , although the effect is subtle. Shelf This parameter effects all filter types. It allows a certain amount of unfiltered[...]

50 components of the reverb except for early reflections, etc.) is passed through a simple 2x2 matrix. This provides an encoding of the tail that dramatically changes its spatial characteristics.
