User manual ALESIS MIDIVERB 4 REFERENCE MANUAL

[. . . ] ALESIS MidiVerb 4 Reference Manual Introduction Thank you for purchasing the Alesis MidiVerb 4 Multi Effects Processor. To take full advantage of the MidiVerb 4's functions, and to enjoy long and trouble-free use, please read this user's manual carefully. How To Use This Manual This manual is divided into the following sections describing the various modes of the MidiVerb 4. Though we recommend you take time to read through the entire manual once carefully, those having general knowledge about effects devices should use the table of contents to reference specific functions. Chapter 1: Your First Session with the MidiVerb 4. [. . . ] If the MIDI clock's tempo changes, the MidiVerb 4 will chase it. If the MIDI clock signal is discontinued, the delay time will remain set to the last tempo which the MIDI clock had been running at. The Note parameter determines what note value the MidiVerb 4 should synchronize to. For example, if you set the Note value to 4, then you can synchronize to the quarter-note beats of the incoming MIDI clock. If instead you set the Note value to 8t, you can synchronize to eighth-note triplets relative to the incoming MIDI clock signal. You can also set the Not value to a dotted-note variation, such as *, which lets you synchronize to the dotted-eighth-note beats relative to the incoming MIDI clock signal. For more information about using MIDI with the MidiVerb 4, see Chapter 6. Delay & DLY These effects are mono, less processor-intensive versions of the Stereo Delay effect, used in the Multi Chain Configurations Delay->Realroom, Chorus->Dly->Room and Flange->Dly->Room; the Double Configuration Realroom+Delay; and the Dual Mono Configurations Delay:Delay, Chorus:Delay and Flange:Delay. They provide only high frequency cutting ability with no control over the low frequencies. Setting Delay Time Using Tap Tempo You can adjust the delay time using a technique called "tap tempo". By tapping the button which corresponds to the Tap parameter, you can have the MidiVerb 4 follow your tapping and adjust its delay time to match the tempo you are using. If the Footswitch parameter (UTILity mode) is set to Control, you can tap your delay time by repeatedly pressing down on the footswitch. You can also adjust the delay time using tap tempo from the audio source being routed to the MidiVerb 4's input(s). This can be done in two ways: · · Hold the button which corresponds to the Tap parameter; or Hold down the footswitch (if the Footswitch parameter is set to the Control function). While using either of these methods, feed signal to the MidiVerb 4. This could be done by hitting a drum, plucking notes on a guitar or keyboard, or by singing some "doot doots" into a microphone (depending on what is connected). Note: When the Footswitch parameter is set to the Control function, you can control tap tempo as described above while in either Program mode ([PROG] button lit) or Edit mode ([EDIT/PAGE] button lit), unlike when using the front panel for tap tempo which requires that you be in Edit mode. For more information on connecting a footswitch and selecting the Footswitch parameter's function, see Chapter 2. 34 MidiVerb 4 Reference Manual Overview of Effects ­ Chapter 3 Pitch Effects The Pitch effects alter the pitch of a signal in various ways to produce "layered" timbres that are more complex than the original signal. Although some of these effects can sound similar to one another depending on the parameter settings, each is achieved differently and can be quite dramatic under the right circumstances. Pitch effects are achieved by splitting the signal into at least two parts, effecting the pitch of one of the parts, then mixing them back together. This eventual mixing is essential since the overall sound of the effect is achieved by the actual difference between the dry, uneffected signal and the effects signal. The various types of Pitch change are: Stereo Chorus The Chorus effect is achieved by splitting the signal into three parts with a dry signal and a separate Detuning section for both left and right channels. When the left channel is detuned sharp, the right is detuned flat, and vice versa. The detuning is further effected by being modulated by an LFO (low frequency oscillator) which causes the detuning to vary. Many variables are available in this scheme: the Predelay can be varied, the LFO depth can be varied, the LFO speed can be varied, and a portion of the detuned signal can be fed back to the input to increase the effect.

Re-initializing To re-initialize the MidiVerb 4, hold down both [PROG] and [D] while turning on the power. This will reset all Utility parameters to their default settings, and will recall Preset 01. 7 Important: The Programs in the User bank are erased when re-initializing the unit this way. Be sure you have stored these Programs into some sort of data storage device via MIDI System Exclusive before performing a re-initialization (see Chapter 6). Checking the Software Version MidiVerb 4 Reference Manual 63 Chapter 7 ­ Troubleshooting The current software version may be determined by holding [PROG] and pressing [EDIT]. [. . . ]
