The NOISE parameter “looks” only at exterior causes of the signal, whereas the XTALK parameter “looks” at all of the other triggers rm4 the D4 to determine whether the “soft” signal it is receiving is actually a “real hit”. Note that any aledis generated by the D4 would be recorded into the sequencer as well.

The third Ext Trig page shows two parameters. Also, an unnecessarily high XTALK setting actually suppresses the sensitivity of the trigger input, resulting in the occasional loss of softer hits.

A higher value adjustment equals greater suppression of the dm, a lower value equals less suppression. A cursor underline will appear under whichever parameter is ready to be edited.

Ext Trig Determines which trigger inputs will trigger which drums, and sets up trigger input response for the most reliable triggering. Press and hold the Drum Set function button. For example, the Voice selection screen shows: This dm44 you to hear the currently-selected sound whenever you poke the button. For more detail on these and other operations, refer to Chapters Press the Store button. This period indicates that the input is reaching it’s full dynamic range.

For this scenario lets use the bass as the reason the surrounding noise level is making proper triggering difficult. Images from Perfect Circuit Audio. The sounds cover the whole gamut, from great acoustic drum types to electronic drum sounds.


When experiencing an interaction problem, the trigger that needs adjustment is the pad that is false triggering, not the pad being struck. This can be useful for auditioning the various preset Drum Sets.

One possible application is to use one stereo pair for a mix of drum sounds, and the other stereo pair as two individual outputs for specific drum sounds that may need separate processing. Engineers and musicians can also trigger drum sounds from the D4 using the trigger inputs and any external sound sources from tape or other studio gear.

They were used for everything manuak sound generation to storing parameters in memory for later recall.

Otherwise, the data will be lost. Review by Tim Goodyer. In the case of a brand new D4, this is the first of the unit’s 21 Drumsets – Drumset 00 “Standard Stuff”. After naming the Drum Set and selecting where it should be stored, press the Store button again. Dn4 the Data wheel to select the note that will be assigned to the selected trigger input.

aless This is the signal strength that the transducer is sending to the triggers in the D4. An overview of the alsis and applications of the MIDI interface. This is handy if you want to route MIDI data appearing at one device to another device as well. Output Selects one of the two sets of stereo outputs. As mentioned in section 1 ,4D, a period after the Drum Set number indicates it has been edited. This is evident when shortly after the initial strike to a pad, a second trigger from the same pad is generated, or it “double triggers”.

Using the bar graph meter, adjust the level according to the severety of the false triggering.

Plug the left Aux output into a third channel panned to center for now and the right Aux output into a fourth channel also panned to center for now. Using the meter, adjust the level to select a “hotter” than usual Vm4 setting.


Actually, the term “beatbox” doesn’t quite fit the D4, since one of the few things it’s lacking is onboard sequencing.

The lower right, two-digit number represents the D4 Drum Set that will be selected in response to the displayed Program Change number. Use alesus Data wheel to select the desired Program Change number.

It’s adjustment is very similar to that of a tape recorder’s VU meter. Usually, each voice plays one note at a time, so the number of notes you can aelsis at one time will be limited by the available number of voices. Higher settings are useful when trying to extract drum sounds from tape where other sounds are present; often the snare or kick drum will be louder than other sounds, so setting the threshold above the other sounds will allow the snare or kick to trigger the D4.

These transducers can be plugged directly into the D4 trigger input, which will convert the trigger’s signal to MIDI information. So here it is, check it out; 99 akesis drums, 99 snares, 55 cymbals, ,anual toms, 76 assorted percussion voices, 80 “effects” sampled in glorious stereo at 48kHz, packed into a single rack space complete with 12 maual inputs equally suited to use with drum pads, drum machines and signals on tape.

Whenever possible, try to aim them so they are not facing directly towards your set up. The Alesis D4 is useless.
