With its massive sound, hands-on ease, and affordable price, the GAIA SH-01 is a high-performance value with old-school charm. The triple-stacked engine puts potent virtual analog synthesis under your fingertips, yet the control panel is so fun, friendly, and inviting, even first-timers can create great sounds. The signal flow is simple to grasp, with logically arranged knobs, sliders, and buttons. Hands-on control and fat sound make this little powerhouse a joy for music students, songwriters, session players, and live performers of all styles and skill levels. keyboard37 keys (velocity sensitive)Maximum Polyphony64 voicesSound Generator SectionVirtual analog synthesizer sound generator (Number of part: 1) (Oscillator + Filter + Amp + Envelopes + LFO) x 3 PCM sound generator (Number of parts: 15)Patch MemoryPreset: 64 User: 64OSC SECTIONOscillator waveformSAW SQUARE PULSE/PWM TRIANGLE SINE NOISE SUPER SAWKnobs/SlidersPITCH DETUNE Pulse Width Pulse Width ModulationEnvelopeAttack Decay Envelope DepthModulationOscillator Sync Ring Modulation (Tone 2's OSC 2 is applied as modulation to Tone 1's OSC 1.)FILTER SECTIONFilter TypeLPF HPF BPF PKG (-12 dB/-24 dB)KnobsCUTOFF RESONANCE KEY FOLLOWEnvelopeAttack Decay Sustain Release Envelope DepthAMP SECTIONKnobsLEVELEnvelopeAttack Decay Sustain ReleaseLFO SECTIONLFO ShapeTRIANGLE SINE SAW SQUARE SampleKnobs/SlidersRATE FADE TIME PITCH DEPTH FILTER DEPTH AMP DEPTH Tempo SyncON/OFFEFFECTSDISTDistortion Fuzz Bit CrashFLANGERFlanger Phaser Pitch ShifterDELAYDelay Panning Delay (with tempo sync function)REVERBReverbLOW BOOSTLow BoostKnobsControl 1 LevelOTHERControllersPitch Bend/Modulation lever D BEAM ControllerArpeggiatorPreset pattern: 64Phrase RecorderUser: 8 Number of Track: 1Jacks/ConnectorsOUTPUT jacks (L/MONO, R) (1/4 inch phone type) Headphone jack (Stereo 1/4 inch phone type) PEDAL jack (TRS phone type) MIDI Connectors (IN, OUT) USB COMPUTER (supports USB Hi-Speed Audio/MIDI) USB MEMORY (supports USB 2.0 Hi-Speed...
