1 CHAPTER 1: INTRODUCTION Thank you for purchasing the Alesis D4 Drum Sound Module. The D4 provides over 500 high-quality drum/percussion sounds (many of them in stereo), that use the same drum recording expertise responsible for making the SR-16 and HR-16 standards in the music world. And thanks to Dynamic Articulation, which triggers different sa[...]

2 • Velocity-sensitive Preview button. Audition sounds at the D4 itself, so you don’t have to go back and forth between a controller and the D4 when making drum kit assignments or checking out sounds. • Headphone jack. This is excellent for practicing, or for creating drum kits while other activity is taking place in the studio. • Hi hat pe[...]

3 Power MIDI THRU/OUT Jack MIDI IN Jack Main Output Jacks Trigger Jacks Footswitch Jack Aux Output Jacks 1.2A Installation For most applications the D4 should be installed in a rack frame so that you can tap the Preview button without causing the unit to slide around. The D4 generates very little heat so it is not necessary to leave an empty space [...]

4 The D4’s drum sounds can be triggered by non-MIDI electronic drum pads, audio signals from tape, drum sounds from other drum machines, etc. 1. If you ’re using a hi hat pad, connect its output to rear panel trigger input 1. 2. Connect up to 11 more pads to any of the remaining 11 rear panel trigger inputs. 1.2E Hook Up Power (rear panel) 1. L[...]

21 2. Turn the Data wheel to select the desired Drum Set root note.[...]

22 4.1 MIDI CHANNEL SELECTION The D4 can receive and transmit MIDI data in Omni mode (receives data appearing on any of the 16 MIDI channels, transmits data over channel 1) or Poly mode (transmits and receives over any one of the 16 MIDI channels). Use Omni when playing the D4 from an external MIDI controller (MIDI drum pads, MIDI keyboard, etc.) s[...]

23 Program Change commands can change Drum Sets at any time, including while the D4 is playing. A Program Change Table (section 4.5) determines which Drum Set will be called up in response to a particular Program Change number. The default is Program Changes 00-20 call up Drum Sets 00-20; so do Program Changes 21-41, 42-62, 63-83, 84-104, and 105 t[...]

24 99 Non-Registered Parameter LSB (0-127) This works similarly to controller 98 but the controller value selects the Least Significant Byte of the parameter to be controlled. 121 Reset All Controllers (0) Any value sent for this controller resets volume to maximum, pitch bend to zero, and restores all non-registered parameters to their default val[...]

25 3. Use the Data wheel to select a status of On (the D4 responds to controller messages) or Off (the D4 ignores controller messages). 4.5 PROGRAM CHANGE TABLE 1. The fourth MIDI page shows the Program Table. Example: PROGRAM TABLE 0 00 = 00 The lower left, three-digit number represents the incoming Program Change number. The lower right, two-digi[...]

26 which receives all channels) to retrieve this data. It’s a good idea to include the channel assignment in the System Exclusive file name to prevent possible confusion. To back up: 1. Connect the D4 ’s MIDI Out to the MIDI In of the other D4 or system exclusive storage device, such as the DataDisk. 2. Select the fifth MIDI page, Sysex Backup.[...]

27 6. Press the D4 Store button. The D4 display says SENDING SYSEX DATA OUT MIDI… and the DD display says RECEIVING Alesis D4 to indicate that data has been received. 7. To prevent future confusion, name the DD file using the DD NAME function. 4.7 RECEIVE DATA FROM ANOTHER MIDI DEVICE The D4 will automatically load D4 system exclusive data presen[...]

28 CHAPTER 5: EXTERNAL TRIGGERING External triggering has three main uses: • Driving D4 sounds from electronic drum pads. Some electronic drum pads provide MIDI triggers when hit; these can feed directly into the D4’s MIDI input. Other pads generate analog triggers, which can interface with the trigger inputs. • Using contact transducers (tri[...]

29 About Trigger Parameters The D4 now offers five user controllable trigger parameters. These are: • VCURVE. This represents the velocity curve, or the sensitivity of the trigger input. There are eight separate curve tables, 0 through 7. Using these settings it is possible to adjust the D4s' triggers to accompany a wide variety of playing s[...]

30 This chart represents three signals which are "seen" by the D4. Signal 1 is a legitimate hit from the snare pad. Signal 2 is the Tom 1 pad, but it is not a hit. It is the pad being triggered by stand vibrations from the first snare hit. Signal 3 is a second "real" hit from the snare pad. As you can see the XTALK threshold is [...]

31 Selecting a higher DCAY value (long decay times) will allow for the most reliable triggering but may miss quickly repeated hits. Lower DCAY values (shorter times) will respond to quickly repeated hits but may be more prone to false triggering. Experimentation with these levels is necessary to achieve the proper results. Example: This chart simul[...]

32 • NOISE. The noise floor is is the signal level threshold a vibration or sound must exceed before it can trigger a drum sound. When selecting lower values, very soft signals (hits) will trigger the D4. While this allows for the greatest sensitivity, there’s a chance that unwanted, exterior signals such as vibrations from drum risers, bass ca[...]

33 2. Place the cursor under the TRIG parameter. 3. Turn the Data wheel to select the desired trigger for editing. 5.1 TRIGGER NOTE SELECTION Each trigger can be assigned to any MIDI note number, which is associated with a corresponding drum sound (programmed according to the instructions in section 3.0). Trigger note assignments are recalled as pa[...]

34 Note: The setting of 0, Unassigned, is selected by rotating the Data wheel fully counterclockwise. This is a special case VCURVE setting which allows a trigger input to contribute to the D4’s master suppression threshold. However, it will not trigger any sounds or MIDI note messages. In certain circumstances this setting can help suppress fals[...]

35 3. Go to the next page and set the XTALK, DCAY and NOISE levels all to 00. This low level will allow the maximum signal to be detected by the D4. 4. Press the EXT TRIG button again to get to the GAIN page. Using the bar graph meter, adjust the level according to the severety of the false triggering. If notes are constantly triggering, use a high[...]

36 5.3 TRIGGER PARAMETER SELECTION To compensate for differences in transducer outputs, the crosstalk, decay time, and noise floor level for each trigger can be set independently. These are Global settings that apply to all Drum Sets. 1. The second Ext Trig page shows four parameters. Example: TRIG: 0 2 XTALK:30 DCAY:10 NOISE:00 As with the other s[...]

37 3. Place the cursor under the XTALK parameter. While you hit the snare pad (triggering the tom pad) gradually raise the crosstalk level of the tom 1 pad . 4. Continue to raise the level until the tom pad stops triggering when you apply hard hits to the snare pad. By using this technique, you have isolated the problem drum, and made it easy to &q[...]

38 5.5 TRIGGER DCAY CONTROL SELECTION If a pad or drum "double triggers" when it is struck, it may be necessary to adjust the DCAY level. 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". Note: With certain pads it may not be necessary to adj[...]

39 Remember : In keeping potential problems to a minimum, it is always a good idea to try to keep some distance between your pad or drum kit, and nearby speaker cabinets (especially bass cabinets). Whenever possible, try to aim them so they are not facing directly towards your set up. Also, avoid unsteady drum risers and hardware. 5.7 TRIGGER GAIN [...]

40 4. To aid in the adjustment of this parameter, strike the pad or drum whose transducer is plugged into the selected input. The lower LCD line will turn into a bar-graph meter that shows the peak strength of the transducer signal. Adjust the gain so that a powerful strike results in the meter reaching the right-most side of the display, and a per[...]

41 5.8A Understanding Hi Hat Pedal Mode This is a feature for hardcore drummers. It’s a little complicated, but hang in there— the D4 finally gives you a way to get truly realistic hi hat effects with electronic drums. An acoustic hi hat produces three main types of sound: • Open hi hat. The pedal is up so that the upper and lower cymb als do[...]

42 Striking the pad while the footswitch is held down plays the closed hi hat sound.[...]

44 machines) can often transmit and/or receive additional MIDI timing messages that keep other rhythmically-oriented units in a system synchronized with each other. An optional MIDI Thru jack provides a duplicate of the signal at the MIDI In jack. This is handy if you want to route MIDI data appearing at one device to another device as well. Some d[...]

45 Pitch Bend This “bends” a note from its standard pitch. Continuous Controller Footpedals, breath controllers, and modulation wheels can vary sounds as you play, thus adding expressiveness. MIDI allows for 64 continuous controllers (these act like potentiometers in that you can choose one of many different values) and 58 continuous/switch con[...]

46 124 Omni Off (0) 125 Omni On (0) 126 Mono On (0-16; 0=Omni Off) 127 Poly On (0) 6.3B Mode Messages There are two messages that determine the MIDI mode (i.e., how the D4 will receive MIDI data). The “Omni” message determines how many channels will be recognized. Omni On means that data from all channels will be received; Omni Off limits the n[...]

47 Continue Unlike a Start command, which re-starts a sequencer or drum machine from the beginning of a song each time it occurs, sending a continue message after stop will re-start units from where they were stopped. 6.5 BOOKS ON MIDI The preceding does not substitute for reading a good book on the subject of MIDI.
