		Grp Synthesizer A8

Descrizione Prodotto:
Il Grp Synthesizer A8, uno dei sintetizzatori non modulari dalle dimensioni più imponenti mai realizzati, si presenta al mercato internazionale come uno strumento in grado di fornire al musicista un sintetizzatore dalle caratteristiche che solo un modulare è in grado di fornire. Privo di patch-cords sostituiti da comodi commutatori e con una generosa dotazione di moduli, l’ A8 è in grado di fornire infinite combinazioni sonore.
Specifiche Tecniche:
• Analog VCOs with 3 FM sources, 2 PWM sources, Tune, Fine Tune, Octave, Hard Sync, Sub Oct -1/-2, Waveform Select (sine, triangle, triangle + saw, saw, square w. variable width, square + saw) • 2 Ring Modulators • 1 Noise Generator (white, pink, low freq) • 2 analog VCF Transistor Ladder 24dB/Oct LowPass, with Cutoff Freq (20-20.000 Hz), Resonance (from 0 to self oscillation) • 2 analog VCF State Variable Filter 12 dB/Oct with indipendent controls for Cutoff Freq (20-20.000 Hz), Resonance (from 0 to self oscillation), four filter modes (12 dB lowpass, 12 dB high pass, 6dB band pass, 6 dB band reject) • 2 Fixed Filter Banks with 14 band: 12 band pass 12dB/Oct (125, 175, 250, 350, 500, 700, 1.000, 1.400, 2.000, 2.800. 4.000, 5.600 Hz), 1 low pass 24dB/Oct @ 88 Hz, 1 high pass 24 dB/Oct @ 7.000 Hz. • 24 analog VCAs on signal path (much more on modulation routings), dynamic range better than 84 dB • 3 Audio Mixers (2 for Upper & Lower sound sources, 1 for Upper + Lower signal paths) • 1 Auto Pan Module • 4 Six Stages Envelope Generators DAHDSR (from 1msec to 15sec) on VCFs and VCLFOs • 3 Four Stages Envelope Generators ADSR (same range as above) on VCAs and Auxiliary • 2 VCLFO with frequency range 0.05-2.500 Hz, multi wave (sine, triangle, positive ramp, negative ramp, square w. variable width), offset full positive on output • 1 aux performance LFO with frequency range 0,1 - 2.500 Hz, shape variable (ramp-triangle-saw/pulse 01%-square-pulse 99%), LFO amplitude under control of modulation wheel or channel aftertouch • 1 Sample & Hold with sync capabilities on Envelope Generators • 1 Step Sequencer (1x16 or 2x8 mode) available for VCOs freq, VCOs PWM, VCFs Freq, EGs gate; internal clock or MIDI clock w. divider/multiplier or analog external clock w. divider/multiplier; several running modes (forward, backward, fw-bw, pendulum, gate, repeat step w. different combinations and repetitions number, one shot/loop); all main functions under external cv/gate control; each step gate can be routed to Upper or Lower path control; each column can have different lenght • 2 Portamento Controls for Upper and Lower signal path • 1 A-440 Hz reference tone generator, w. quartz accuracy • Two huge VuMeters for Left - Right audio level reading • MIDI Interface w. 12bit D/A for the following messages: note on/off, initial key velocity, channel aftertouch, pitch bend, modulation wheel, sustain pedal, volume. • The instrument architecture can be configured in Upper/Lower mode (two indipendent signal path, with different sounds) or Mono combination, with the whole control panel on a unique big patch. MIDI In data can be routed for Mono, Dual or Poly mode (all 6 VCOs under the same MIDI channel; separate Upper & Lower MIDI Channel for monophonic operation; biphonic operation under the same MIDI Channel) • The instrument can be controlled simoultaneously with MIDI In and CV/Gate In or with indipendent routing for MIDI (Upper or Lower) and CV/Gate (Upper or Lower); same as above for the internal Step Sequencer. • Separate Audio Outputs for Upper Channel, Lower Channel, Upper+Lower Channel; each channel has full stereo output Left-Rigth All specifications subject to change.
