User manual ALESIS MIDIVERB

[. . . ] A basic introduction to getting the unit up and running, auditioning the factory Programs, adjusting levels, comparing and storing edited Programs. Deals with the necessary preparation before using, including connections to other components, such as instruments, mixing consoles, patchbays, and multitrack recorders. A detailed look at the signal processing capabilities of the MidiVerb 4 and the concept of multi-effect programming. A guided tour for programming typical single and multi-effect applications. [. . . ] Each of the 3 "taps" have individual delay, level, panning and feedback controls. By adjusting the delay time of each tap, you can create sophisticated rhythms. BPM Mono Delay This is a mono delay which can have its delay time parameter set to a specific tempo or BPM (beats per minute) value. This allows you to reference the delay time to the tempo of the music you are playing, rather than searching for the correct delay time in milliseconds. An additional parameter, called Note, is used to determine what beat value your tempo represents. For example, if you set the note to 4, then you can set the tempo using quarter-note beats to establish delay time. If instead you set the Note to 4t, the same delay tempo setting will play faster because it is simulating quarter-note triplets in relation to the selected tempo. You can also choose dotted-note values, such as 4d or 8d for different rhythms relative to the selected tempo. MidiVerb 4 Reference Manual 33 Chapter 3 ­ Overview of Effects Synchronizing to MIDI Clock It is possible to control the delay time of the BPM Mono Delay effect from an external MIDI clock source, such as a MIDI sequencer or drum machine. Any device which can output MIDI clock can be used to control this Configuration's delay time. If the "Tempo" parameter is turned all the way down, below 000, the value in the display will read "EcL", which means "external clock". The delay time will now be controlled by the MIDI clock signal received at the [MIDI IN] port coming from an external source. If the MIDI clock's tempo changes, the MidiVerb 4 will chase it. Each of the four signals has a separate Predelay variable, allowing you to change the "rhythm" of the phasing. Chorus This is a mono, less processor-intensive version of the Stereo Chorus effect, used in the Multi Chain Configurations Chorus->Realroom and Chorus->Dly->Room, the Double Configuration Realroom+Chorus, and the Dual Mono Configurations Chorus:Chorus and Chorus:Delay. MidiVerb 4 Reference Manual 35 Chapter 3 ­ Overview of Effects Stereo Flange First used in the 1960s, "flanging" was achieved by the use of two tape recorders that would record and play back the same program in synchronization. By slowing down one tape machine, and then letting it catch up with the other, different phase cancellations would occur at different frequencies. Since the slowing down of the tape machines was done by hand pressure against the flanges of the tape supply reels, the term "flanging" came into being. Flanging is similar to chorusing , but modulates the delayed signal over a much shorter delay range (typically 0-12 ms). This produces a "jet airplane"-like sound. The flange modulation sweep can be triggered by the audio input (either the left or right input, or both), in order to sync up with the rhythm of your playing. You can adjust the attack and release threshold of this audio triggering function. In the case of the Stereo Flange, the signal is split into three parts with a dry signal and a separate Delay section for both left and right channels with one channel flanging up while the other channel flanges down. Once again, this causes the effect to become more pronounced and dramatic. When flanging was done using two tape machines, it was possible for one to be behind the other, catch up and then go past the other. This is called passing "through zero". The "zero" point is when both signals were in perfect synchronization. [. . . ] I f t his do esn't wo rk, try reinitialization. Cascade mode is turned on. MIDI channel is set to a different number than the controlling device. Bypass function is on with Dry Defeat on. Bypass function is on with effect's MIX parameter set to 0%. Cannot adjust an effect's Dry Defeat is turned on. MIX parameter (displays "- -" instead of a number from 0-100%). [. . . ]
