DigiTech DSP 128 Plus Digital Signal Processor Vintage Rack

Some effects units sound thin, others warm. High values tend to produce a metallic, ringing sound, and diigitech values produce a grainy, fluttery sound: Reverse Reverb, Delay, Filter With the delay feedback parameter, infinite hold is enabled when the parameter is raised to its maximum value by a remote controller. Although any Continuous Controllers apart from Polyphonic Aftertouch can be used to control parameters, Note Velocity cannot, which is a bit of a shame as it’s the means of expression that is most easily available and controllable for the average keyboard player.

The effects produced by the DSP Plus emanate from four processing sections: Hot on the heels of the Multiverb and Quadraverb comes Digitech’s contender for the title of best ‘four effects at once’ signal processor.

Music Equipment Manuals and Documentation. The maximum delay time varies according to the algorithm used, as this determines how much processing power is available for each effect.

The LED display can be varied so that as you change parameters they scroll into the display area or pop into it. Thus, the level or decay time of reverb say can be modulated with a synthesizer’s mod wheel, or anything else that can generate Continuous Controller information. The default configurations for these are bypass and to switch in infinite repeat, but they can be reconfigured to step backwards and forwards through the programs and they dogitech be used with DigiTech’s three-button footswitches FS and FS to step through assignable program numbers.

John Walden joins the digital age Even the algorithm section was not completely correct, although the meaning of the parameters could be gleaned from the algorithm list.


Also, the pages which should have contained details of the factory presets were totally blank so the uses to which some of the presets could be put were not always obvious. The quality and smoothness of reverb produced by a particular diffusion level varies according to the size of the simulated environment, and larger environments tend to require higher diffusion values.

This control is limited to dogitech controllers so note velocity, aftertouch and the like are not catered for. The best starting point for creating your own programs with this algorithm are the Normalised Reflectivity 0.

Independent initial delay times up to 1. Please Contribute to mu: Bearing in mind that the input sensitivity of the DSP Plus is switchable to cope with both line digitecj instrument level signals, it seems that Digitech have very much kept the guitarist in mind when designing the DSP Plus.

On powering up, the display reads ‘P 1’, indicating that Program 1 is currently selected. The first six algorithms the only ones to allow four effects at once have a maximum delay time of 0. Put the lot together – in any one of a number of permutations – and you can produce some very clever effects indeed. It will take quite a hefty signal before peaking.

Good though this is, the fact that it comes after the release of the ART Multiverb and Alesis Quadraverb somewhat takes the edge off the excitement.

If it diitech set to Wet you won’t hear a thing. My gut reaction on first encountering the DSP Plus was pretty much along the above lines, that here was another in a recent series manaul improved multi-effects processors.

A few milliseconds difference between the placement of the repeats at each position is enough to give the echoes a refreshing stereo depth and movement. The gated and reverse reverb effects provided by two dedicated algorithms are both good, and allow for considerable control to be exercised over effects that can all too easily sound a little cliched. A good trick is to set the initial delay times for the three stereo positions to almost – but not quite – digtech same value.


If the feedback delay time is set to a greater value than all three of the initial repeat delays, the ‘rhythm’ of the initial three repeats is repeated over and over.

Digitech DSP Plus (SOS Apr 89)

Both the DSP and the Plus will store programs – so no prizes for guessing the derivation of their names. Some even simply flag the error and continue working. These determine the volume of the simulated listening environment, and the reflectivity of its surfaces. The EQ section in these six algorithms consists only of a low-pass filter, with programmable roll-off frequency. In practice, to kill the effect I found it far easier to turn the Mix control to Dry.


digjtech Not particularly friendly, to my way of thinking. I found this rather odd as my other equipment can be reset by changing patch. However, after delving deep into the facilities of the machine, its own character and unique features became apparent, demonstrating that it is without doubt a worthy addition to the growing range of affordable professional effects dps.

In the absence of program names, this is really useful. The display will also show changes made to a a parameter’s values from a MIDI controller – a useful function. Small room, Delay, Chorus, Filter 6. One algorithm is dedicated to a nine-band graphic but with no effects.

Many parameters will be self-explanatory to most musicians but some, particularly those used with reverb, may not be dsl obvious. By carefully choosing the parameters you can determine the size and absorbency of the reverb environment as well as the position of the listener in relation to the sound. I have spent a good deal of time and space describing the Ultimate Reverb algorithm, but I make no apologies for this as it’s one of the DSP Plus’s most interesting features.

Further variation can be introduced by the delay section, which is placed in series after the reverb.
