Peavey DPM4 Upgrade Kit New Old Stock

This a rare New in the Box Peavey DPM 4 Upgrade kit. This will upgrade your DPM3 series keyboard to a DPM 4. It includes a set of rom chips, a new board to replace one of the original boards since the DPM3 design was maxed out and a new board was needed to include the new features of the DPM4. It also has instructions, a manual to the new features and new labels for the front panel buttons.

Here's what a DPM4 is:

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.
