The SH-09's exceptional quality combined with its unique live performance and interfacing features allow it to surpass the capabilities of many larger, more expensive synthesizers. The VCO section features virtually rigid pitch stability in even the most difficult conditions and produces precise, rich waveforms including: Noise, Sawtooth, Square and variable Pulse Wave with both LFO and Envelope Modulation options. A Sub Oscillator produces any one of three parallel tones that may be mixed with the VCO at the internal Audio Mixer for thickness and extra flexibility without introducing tuning difficulties. Both the VCO and Sub Oscillator may be modulated by the LFO Modulator which includes Square Wave, Delayed Sine Wave or Sample and Hold options. The VCF section of the SH-09 features the highest quality 24 dB/octave Low Pass Filter available for stability, flexibility and rich, deep tones. The extra flexibility is achieved through the SH-09's modulation options including: a positive or inverted envelope, an envelope follower for processing external instruments, three LFO modulation options, resonance control that may be pushed into self-oscillation for use as an extra sine wave oscillator, and control of the filter from the Bender section. The VCA may control volume with the Envelope Generator, directly from the Keyboard Gate, or be fully opened with a Hold switch for added flexibility. This control is enhanced by the complete four slider ADSR Envelope Generator which may be activated by either the Keyboard Trigger and Gate,, the Keyboard Gate alone, or by the LFO and the Keyboard Gate together. These options combine with other control possibilities to make the SH-09 an exceptionally sensitive musical instrument. The LFO Modulator control offers Sine Waves with or without delay, Square Waves, Sample & Hold and a separate Sine Wave without delay for the Pulse Width Modulation section. The LFO speed is fully adjustable and indicated by LED for precise, predictable control. The SH-09 Bender section is the finest available. The center sprung lever returns to its origin automatically for quick, easy, musically secure playing. The Bender may control pitch through the VCO or tone through the VCF either separately or simultaneously with amounts preset by the performer for exact, predictable control of the synthesizer. Interface options on the SH-09 include industry standard CV and Gate inputs and outputs for connection with Roland digital sequencers, other Roland synthesizers and with any other equipment offering 1 volt per octave Keyboard Control Voltage and positive voltage Keyboard Gate inputs and outputs. Other instruments may be processed through the SH-09 using the self contained External Audio Input with the Envelope Follower contained in the VCF section. The SH-09 is equipped with a Va inch phone jack output for connection with any conventional amplification and with a separate Vi inch stereo phone jack connection for headphone monitoring through self-contained headphone amplifier. A connection cable is included with options for connection to either a Vi inch phone jack socket or any female RCA jack socket. Front and Back Panel Layout 2 EXT AUDIO IN INPUT GATE CV P 1, OUTPUT Control Descriptions_ 3 Modulator Section The Modulator is a controller used tor producing regular changes in pitch and tone in the VCO and VCF sections and for repeatedly triggering the Envelope generator. The Modulator is based on a Low Frequency Oscillator (LFO) producing waveforms with speeds ranging from 0.2 to 25 Hi The Sample and Hold mode also produces random signals by sampling the output of the noise generator at a rate determined by the LFO. Morip Switch This switch determines which waveform will be used for VCO and VCF modulation. The three options include: r\j (sine wave), fU (square wave), and Random (S/H) for the Sample and Hold output Rate Control The Rate sllder controls the frequency or speed of change for all Modulator outputs. Raising the control increases the frequency, which may be monitored with the associated flashing LED. ^ Delay Time Control When this control is raised, pressing a key on the keyboard will delay the entry of the LFO sine wave to the VCO and VCF. Raising the control increases the delay time, and lowering it fully results in a continuous output with no delay. VCO (Voltage Controlled Oscillator Section) The VCO is the basic sound source of the SH-09 and is responsible for the pitches produced and the basic tone color used. Tune Control This small tuning knob controls the overall pitch of the SH-09. The tuning range is ±65 cents. Range Switch The rotary Range switch changes the VCO pitch in exact one octave steps from 2' to 32' for a total range change of four octaves. MOD (Modulator) This slider changes the pitch of the VCO with the Control Modulator output according to the Rate and Mode shape set in that section. Raising the slider increases the amount of chang...
