The DPM® 4 is the newest version of the now popular DPM 3 digital phase modulation synthesizer. Introduced by Peavey Electronics in 1989, the DPM 3 has literally changed the way synthesizers are made. We've also held true to our commitment of keeping you, the player, at the forefront of synthesizer technology by providing you with a steady stream of innovative software upgrades at minimal cost. The DPM 4 is another power-packed step up in the evolution of DPM technology. In addition to the DPM 4, Peavey is proud to announce the DPM 488, an 88-key version of the DPM 4 with the same weighted piano action as the world- famous DPM C8 MIDI controller, in a beautiful high-gloss, black hardwood cabinet.
The DPM 4 features an increased ROM sample wavetable. The original 4 megabyte set offered in the DPM 3 has been increased to a massive 10 megabytes. This new sample set includes a much-improved acoustic piano sample, as well as dozens of new solo and sectional orchestral instruments such as strings, brass, and woodwinds, and many new drum and percussion sounds such as brushed drums, rap drums, orchestral drums, etc.
The DPM 4 also has increased polyphony, offering 32 single oscillator voices as opposed to the 16 dual oscillator voices available in the DPM 3 series. This means you have increased horsepower for creating sequences and complex layered sounds. Of course, all of the standard features which have allowed the DPM 3 to stay on the leading edge are still there, such as 512 Kb of user sample memory (expandable to 1 Mb), two 24-bit dual effects processors, a 9-track digital sequencer, 61 or 88 velocity and pressure sensitive keys, and a 3.5" floppy disk drive, etc. In addition, the DPM 4 and 488 are compatible with existing DPM 3 sound, sample, and sequence disks.
USER SAMPLE MEMORY
The DPM 4 offers 512K of sample RAM with a 1Mb capacity board as standard
equipment. Sample RAM memory gives you extended memory for adding up to 128
alternate 16-bit samples to your palette of sounds. By installing the
optional 512K sample RAM upgrade, the user sample memory can be increased
to a full megabyte. These additional samples can be used in voice programs,
drum kits, and sequences, and since the sample RAM is battery-backed, they
will remain in memory even after the power is switched off. This allows you
to permanently add your own original samples to the menu of on-board ROM
samples, customizing your machine with any sounds you want. Of course,
samples can be saved to disk so you can create an endless library of
different personalities for your DPM 4 and change its character as often as
you like. With the affordable DPM SX or SXII Sampling Expander, you can
record your own 16-bit samples for use in the DPM 4.
SEQUENCER
The DPM 4 features a 9-track on-board sequencer with up to 20,000 notes of
total storage capacity, and offers 50 sequence or "pattern" locations, and
10 "song" locations. Each pattern can be an entire song (up to 999 bars),
or section of a song such as an intro, verse, chorus, etc. These sections
can then be linked together using the "song build" function. This allows
songs to be re-arranged without the typical "cutting" and "pasting"
required with other "linear" sequencers. The DPM 4 sequencer also features
"independent track looping," allowing each of the nine tracks within a
single sequence to have its own loop length. This means that if your drum
track is a 4-bar pattern, but the sequence is 16 bars, you only need record
the drums for four bars, and the track will automatically repeat four
times.
Although a Global Effect is used for each sequence, individual tracks within a sequence have an Effects Send level. This allows you to vary the amount of the selected effect by simply adjusting the Send level. This is handy for times when you need some tracks "dryer (little effect)" and some tracks more"wet (lots of effect)" Adjustments to the send level also allow a different amount of effects to be used on the same instrument in different songs or sections of a song.
Another powerful and unique feature in the DPM 4 sequencer is the ability to use a COMBI (combination)sound for each track. This means that you are able to use four instrument sounds on each of the 9 tracks, offering a total of 36 instruments. Sounds can be layered, split into discrete keyboard zones, and layered or split in key velocity zones, offering flexibility unmatched by other keyboard workstations.
SIGNAL PROCESSING
The DPM 4 offers 2 sophisticated effect processors that can be used to
modify the basic sound programs, with results comparable to what can be
obtained from outboard rack-mount effect devices. Signal processing modules
include time-based effects (reverb, gated reverb, chorus, flanging, stereo
delay), equalization, distortion, and an "exciter" that enhances sounds
through a combination of phase changes and equalization. Signal processing
setups for sounds need not be global; each sound program has its own
associated signal processing parameters and can be processed in a unique
way.
There are two independent effects units (Effect 1 and Effect 2). Each one can include one or two effects (called Single or Dual effects mode, respectively), giving a possible total of up to four signal processing "modules" in all.
DRUM KITS
The DPM 4 contains ten special "multi-sample" waves called drum kits. These
waves consist of up to 32 percussive (or melodic) wavesamples, chosen from
the DPM 4's set of waveforms and assigned to specific keys. Available
waveforms include any of the 10 Mb internal ROM samples, as well as any
custom user samples in Sample RAM. The drum kits can be programmed to
achieve tonal variations that include tuning, panning, amount of effects
and decay on each drum, plus filters on each drum. After building a drum
kit, it remains in memory until altered and can be assigned to a program,
just like any other wavesample.
LOOPABLE ENVELOPES
The Voice Editing section of the DPM 4 features the addition of looping
envelopes, which add incredible texture and dynamic movement to the sounds.
When used in conjunction with oscillator mixes, filtering, or pan position,
looping envelopes enable you to create great new sounds. Although looping
envelopes have appeared on several synthesizers in the past from different
manufacturers, we feel the implementation of this feature in the DPM 4 is
the most flexible ever presented.
In the DPM 4, the envelope can be programmed to repeat steps within the envelope between the sustain level and any of the previous points in the envelope. The progression between Level 3 and the programmed previous point can be looped as a forward progression or a backward/forward progression.
