Tempest is a professional drum machine that generates its sounds using six powerful analog synthesis voices, and uses an innovative, performance-oriented operating system that permits an extraordinary level of control to create, edit, arrange, and manipulate beats in real time without ever stopping. The performance-oriented operating system, ninety panel controls, and bright 256 x 64 dot OLED display work together to provide a tightly integrated, non-stop workflow. Each of the six analog voices has two analog oscillators plus two digital oscillators (with a large bank of included samples), the classic Curtis analog lowpass filter with audio-rate modulation, an additional highpass filter, analog VCA with feedback, five envelopes, two LFOs, an extraordinary variety of analog modulation routings, and stunning sonic quality, warmth, and punch. Although optimized for drum sounds, it excels at tuned sounds as well, and even doubles as a six-voice analog keyboard synth. Sixteen pressure- and velocity-sensitive lit pads are arranged in a 2 x 8 configuration, providing intuitive access to all your fingers and the ideal compromise between the popular 4 x 4 pad arrangement (popular for real-time programming ) and 1 x 16 arrangement (popular for step programming) because Tempest does both. The pads can be used to play thirty-two drum sounds (two banks), mute/unmute the thirty-two sounds on playback, play and arrange sixteen beats in real time, play one sound at sixteen tunings (in a variety of scales) or sixteen velocities, or as sixteen time steps for step programming. The ROLL button permits creating drum rolls or repeated groove patterns by varying pad pressure as the beat records, and doubles as a momentary "stutter" effect when the pads are assigned to play beats. In addition to the six stereo direct voice outputs, there are stereo mix outputs and phones outputs, plus two inputs for foot switches or expression pedals, MIDI in/out and USB. Two pressure- and position-sensitive Note FX slide controllers permit real-time recording of note or beat-wide sound parameter changes into the drumbeat as you play. For example, record simultaneous filter frequency, tuning, envelope decay, and pan changes for each note. The Playback key permits using the slider to override these parameters on playback, which can be recorded back into the beat. Plus, the sliders can be used in performance to alter beat-wide sound parameters like low-pass frequency or resonance, high-pass frequency, envelope attack or decay, and more. Features Two analog oscillators per voice capable of producing sawtooth, triangle, saw/triangle, and variable pulse widthsquare waves, with hard sync Two digital oscillators per voice loaded with over 450 drum samples and waveforms One sub-octave generator per voice (one octave below oscillator 1) One classic Curtis low-pass filter per voice (switchable 2- or 4-pole) with audio rate modulation, self-oscillating in 4-pole mode One High-Pass filter per voice Analog VCAs with programmable feedback level Five envelope generators per voice (ADSR plus hold) 2 LFOs per voice 8 x 8 modulation matrix Hardware MIDI delay per voice Glide (portamento): separate rates per oscillator 16 pressure and velocity sensitive lit pads Two pressure and position sensitive touch sliders 650 Sound Program locations Analog compressor and distortion (available on Main audio outputs) Sophisticated realtime sequencer Roger Linn Designed Swing modes Stunning OLED 256 x 64 display Stereo analog compressor and distortion circuits affect the stereo output mix Beat-synced delay is achieved by generating additional delayed note events within the sequencer A beat-synced "stutter" effect is created entirely within the sequencer by looping short portions of the drumbeat on demand The degree of swing timing can be adjusted in real time during playback. Roger used his entire bag of tricks to make the swing sound very human and natural New Features (os version 1.4) Increased sequence length (up to 128 sixteenth notes, or 8 measures of 4/4) Arpeggiation New modal scales Free-running LFOs Compressor envelope controls Quantize disable A total of 928 new factory sounds, 64 new beats, and 16 new projects
