Dynamic microphones will probably work best. 2. Open your mouth wide when singing into the microphone. ★ Tracking Errors Tracking refers to the ability of the synthesizer VCO to follow the pitch of the input sound. With some instruments, certain playing techniques can produce sound with a fundamental which is extremely unstable. This can cause the synthesizer and direct sound to be of different pitches, or can cause the synthesizer to lose its sense of pitch altogether, as happens when you try to play chords on the input instrument. ★ Input Pitch Limitations The pitch-to-voltage converter has a lower limit of 70 Hz below which the pitch-to-voltage conversion will not be accurate. Also, with pitches which approach this limit, tracking errors can occur more easily. The second string on the electric bass (D one ledger line below the bass cleff) produces a frequency of about 73Hz. 12 • SAMPLE SOUNDS Clarinet Since the square wave already sounds very clarinet-like, it is used as the foundation for the clarinet sound. Oboe The oboe is very rich in harmonics and uses the pulse wave. The VCF RESONANCE control © is raised so as to accent the frequencies at the cutoff point of the VCF. Trumpet The trumpet uses the sawtooth wave. control © The envelope generator is used to control the VCF cutoff frequency to produce a brassy sound. Try various settings of the envelope generator ATTACK Violin The violin sound uses the 8' sawtooth particular phrasing and playing style wave output of the VCO. The VCF desired. CUTOFF FREQUENCY control © is set high. Change the envelope generator ATTACK control © to match the 13 Cello The 'cello sound uses the 16' pulse wave. VCO-2 is used to give depth to the sound. Tune VCO-2 to near unison with VCO-1. Tune VCO-2 to near unison with VCO- 1. Jazz Organ Tune VCO-2 to near unison with VCO-1. Use the VCO-1 SUB oscillator to fatten the sound, if desired. Xylophone The xylophone sound uses the 4' square wave. Adjust the sound using the envelope generator DECAY © and SUSTAIN © controls. 14 Bass Drum Many percussion instrument sounds can be imitated by raising the VCF RESONANCE control © to maximum and using the VCF as the sound source instead of the VCO. The VCF CUTOFF FREQUENCY control ® determines the pitch of the output sound and be adjusted to produce other sounds such as tom toms, congos, bongos, etc. FOLLOW E fl AUDIO MIXER-2 -I»- m m Funny Cat With this sound, the envelope generator is used to control the cutoff frequency of the VCF. With the RESONANCE control © raised, this causes the tone color of the sound to change during the attack portion of the sound. This sound is also good with VCO-2 and/or VCO-1 SUB added/ If the envelope generator settings are changed, there will be a large change in the tone color of the sound. ,0 0 AJDIQ V1IXER-2 □ Synthesizer Drum This sound is produced by means of an oscillating VCF. The frequency produced by the VCF is controlled by the envelope generator. 15 о AUPO MIXER-2 o • • 16 >1 o' AUDIO M1XER-2 V V” 1 o ~= _p_ =U= P (•) •) PEDAL CONT Rotand P/V SVnTH BLOCK DIAGRAM • Rack Mounting the SPV-355 The SPV-355 can be mounted in a standard 19" rack using 6mm screws as shown in the drawing. 6mm screw 19" RACK • SPECIFICATIONS SPV-355 P/V SYNTHESIZER INPUT SECTION Controls THRESHOLD Control © INPUT SELECTOR Switch © INPUT LEVEL INDICATORS O SYNTHESIZER SECTION controls Dual VCO (VCO-1, VCO-2) WAVEFORM Switch M nj n_J ) © RANGE Switch (4', 8', 16') © MASTER TUNING Control (±250 cents) © A TUNING Control (±1200 cents) © B TUNING Control ( ± 1200 cents) TUNING INDICATORS (A, B) VCO-1 SUB (1 octave down, pj ) PORTAMENTO Controls PORTAMENTO Control (0 —3s) © PORTAMENTO ON/OFF INDICATOR AUDIO MIXER-1 Controls VCO-1 SUB LEVEL Control VCO-1 LEVEL Control VCO-2 LEVEL Control VCF Controls CUTOFF FREQUENCY Control (10Hz —20kHz) © RESONANCE Control (0 - self oscillation) Qj> PITCH FOLLOW Control © ENVELOPE SLECTOR Switch (ENV GEN; ENV FOL'R) © ENVELOPE LEVEL Control (/V V-0© VCA Controls ENVELOPE SELECTOR Switch (ENV GEN; ENV FOL'R) © ENVELOPE GENERATOR Controls ATTACK TIME Control (1 ms-3.5s)© DECAY TIME Control (2ms-7s)® SUSTAIN LEVEL Control (0-100%)® AUDIO MIXER-2 Controls SYNTHESIZER LEVEL Control © DIRECT LEVE Control © MIX/DIRECT SELECTOR Switch © MIX/DIRECT INDICATOR PEDAL CONTROL SECTION VCO SENSITIVITY LEVEL Control © VCF SENSITIVITY LEVEL Control © CONNECTORS Input and output INPUT Jack O OUTPUT Jack (input/output level = 1:1)© Remote Controls VCO-2 tuning: REMOTE A/B SWITCHING Jack © PORTAMENTO REMOTE ON/OFF SWITCHING Jack® AUDIO MIXER-2: MIX/DIRECT REMOTE SWITCHING Jack © CV & GATE HOLD Jack © PEDAL CONTROL: VCO/VCF FOOT VOLUME Jack © REAR PANEL CV OUT Jack (1 v/oct) © GATE OUT Jack (OFF: 0V; ON: + 15V) © ENV FOL'R OUT Jack (0- + 10V) © CV IN Jack (1 V/oct) © GATE IN Jack (Threshold: +3.8V)© EFFECT SEND Jack ® EFFECT RETURN Jack © POWER SWITC...
