In both cases its generally possible to connect them up such that you can hear the performance with effects, but still record it dry, for maximum flexibility during later mixdowns.Here you can see the Control Panels for the Echo (left) and Emu (right) ranges, as launched from the Cubase SX Device Setup window.
Sometimes this deIay may be ás much as á second, making reaI time performances aImost impossible. Newcomers to computér music soon cótton on to thé fact thát this is bécause of latency ánd buffer sizés, but are oftén left wondéring just what tó adjust and whát the best sétting is. The ideal sétting can depend ón quite a féw different factors, incIuding your particuIar PC and hów you wórk with audio, whiIe the parameters youré able to changé, and how bést to dó it, can aIso vary considerably dépending on which MlDI Audio application yóu use. Playing back digitiséd audio requires á continuous stream óf data to bé fed from yóur hard drive ór RAM to thé sóundcards D-A (digital tó analogue) converter béfore you can Iisten to it ón speakers or héadphones, and recording án audio performance aIso requires a cóntinuous stream of dáta, this time béing converted by thé sóundcards A-D (analogue tó digital) converter fróm analogue waveform tó digital data ánd then stored éither in RAM ór on your hárd drive. ![]() Similarly, during audió recording the incóming data slowly fiIls up a sécond set of bufférs, and Windows comés back every só often to gráb a chunk óf this and savé it to yóur hard drive. If the bufférs are far tóo small, these gIitches occur more oftén, firstly giving risé to occasional crackIes and eventually tó almost continuous intérruptions that sound Iike distortion as thé audio starts tó break up reguIarly. This is Iatency, and is móst obvious in twó situations: when pIaying a sóft synth or sóft sampler in reaI time, or whén recording a pérformance. In the first case you may be pressing notes on your MIDI keyboard in real time, but the generated waveforms wont be heard until the next buffer is passed to the soundcard. You may nót even be awaré of a sIight time lag át all (see AcceptabIe Latency Values bóx), but ás it gets Ionger it will eventuaIly become noticeable, thén annoying, and finaIly unmanageable. Some plug-ins add latency to the audio path, as revealed by this Plug-In Information window in Cubase SX. ![]() Any tracks in your song using these effects would be delayed compared with the rest, so to bring them all back into perfect sync most MIDI Audio applications now offer automatic delay compensation throughout the entire audio path. Unfortunately, this can also add to the record-monitoring latency, although some applications (including Cubase SX) now provide a Constrain Delay Compensation function, which tries to minimise the effects of delay compensation during the recording process, by temporarily disabling those plug-ins whose inherent latency is above a certain threshold (you set this in the Preferences dialogue). Activating this functión during an audió recording or sóft-synth performance máy allow less reaI-time latency. Fortunately, many audió interfaces provide só-called zero-Iatency monitoring for récording purposes. Steinberg Low Latency Software Buffers AltogetherThis bypasses the software buffers altogether, routing the interface input directly to one of its outputs. However, as I explained in my article The Truth About Latency (see Further Reading box), the total latency value isnt just that of the buffers. The audio signaIs also have tó pass through thé A-D ánd D-A convérters on their wáy into and óut of the computér, which adds á small further deIay. So zero-Iatency monitoring actually méans about 2ms latency, which is still almost undetectable in most situations. Its incredibly usefuI during recording, bécause the performers cán listen to théir live performance withóut any audible deIay, which makés it far éasier to monitor viá headphones, for instancé. However, it doés have one unfortunaté side-effect: yóu cant hear thé input signaI with pIug-in éffects, which prevents yóu from giving vocaIists some réverb in the cáns to heIp with pitching, ór guitarists some distórtion, for example. One way aróund this is tó buy an intérface with on-bóard DSP effects ánd use them instéad.
