Elektron Machinedrum SPS-1UW

Synthetic percussion Sequencer (2005)


OVERVIEW Upgraded version of 2001 edition adding with 2MB dedicated DSP sample RAM. UW stands for "User Wave)"  - thanks to the internal flash backup, the user configurable ROM sounds will be retained in memory even after the unit is switched off and then swiftly restored on power-up. The dynamic 12-bit sample engine adds typical grit and character to your samples. No really other changes.

OSCILLATORS  SPS-1 comes with four digital percussion synthesizers. The MD-synths are built of several specialized machines. Each machine is designed to generate one type of drum sound, such as bassdrum or claves, from a set of parameters. 
-TRX is inspired by the classic rhythm machines of Rolands TR-series with analogue modelling.
- EFM  “Enhanced Feedback Modulation” algorithms. The generated sound ranges from realistic acoustic drums to wild, chaotic effect
- E12  is built on carefully processed sampled percussion sounds with individual control. sample based drum machines such Emu SP1200
- PI  is the physically informed MD-synth which simulate the behaviour of acoustic drums.

LFO  LFO-system of Machinedrum is composed of 16 individual dual waveform LFO's, synchronized to the tempo. The LFO's can be routed to any Synthesis, Effects and Routing parameter. 

Effect, midi, sequencer 

EFFECTS dedicated Track Effect System for each of the 16 tracks of MD synthesis. The Track Effects are always at hand with assigned direct controllers. These effects forms a natural extension of the MD-synths and are available to shape the definite percussion sounds. The Track Effect parameters are saved in Kits and can be controlled by the Percussion Sequencer, just like MD-synth parameters. 
The Track Effects consists of five concurrent effects: Amplitude Modulation, 1-band EQ, 24-dB Lo/Band/Hi-pass Resonant Filter, Sample Rate Reduction and Distortion.  The Stereo Master Effect System is composed of the Rhythm Echo delay, the Gate Box reverb, the Dynamix dynamic processor, a Parametric and Hi/Lo-Shelf EQ. The Rhythm Echo and Gate Box Reverb each has dedicated sends from the 16 percussion tracks. The Dynamix processor and the EQ process the mixed main out stereo signal. All settings for the Stereo Master Effects are part of the Kit. 

MIDI Machinedrum uses MIDI as its internal communications protocol. This means that all functions available in the Machinedrum can be controlled externally using the MIDI interface. All knobs and buttons that effect the sound also transmit MIDI messages that can be recorded for external automation. Individual drums and patterns can be triggered using standard NOTE_ON messages. Synthesis, Effects and Routing parameters are controlled using 384 standard CTRL_CHANGE messages.

SEQUENCER  The pattern based Percussion Sequencer of SPS-1 delivers control over 16 tracks of internal percussion synthesis or external MIDI drum trigging. 128 patterns of up to 32 steps are available for instant replay, step edit and realtime recording. Each pattern also offer step programmable Accent, Swing and Slide. The Song mode is straightforward with 256 positions of patterns linked together forming a song. For each step a repeat-value and BPM can be set. There are 32 song slots in SPS-1. 
Machinedrum sequencing comes in two levels: Classic and Extended. In Classic mode the sequencer operates as would be expected of a classic drum machine, with the sequencer separated from the synthesis. Extended mode ties these two together by keeping track of the kit used for a certain pattern. In Extended mode all Synthesis, Effects and Routing parameters can also be locked to fix values for any step. The lock-programming can be done either in step edit or realtime recording. The step programmable Slide-track decides for which steps parameters shift value directly or slide smoothly between the start and end values.
