The VOICE SELECT switch at the DUET position adds the fundamental pitches of the bass guitar strings to the VCO sounds to produce a chorus effect It is necessary to tune the VCO s using the MASTER TUNNING controls so that they match the pitches of the strings For accurate tuning use at least ten minutes for a warm up period after first turn on the power switch Turn the BALANCE control counterclock wise to increase the normal bass guitar sound Setting the BALANCE CONTROL at 0 will produce the normal bass guitar sound only USING THE VCF Let s try the VCF voltage controlled filter section next Set the BALANCE control at 7107 Try slowly lowering the Bass Guitar CUTOFF FREQ control to 0 Note that the sound becomes softer with fewer harmonics The purpose of the VCF is to contro the tone color of the synthesizer sound Next raise the Bass Guitar RESONANCE con trol a little at a time while trying different positions of the CUTOFF FREQ control This produces an electronic type of sound usually associated with synthesizers The two controls CUTOFF FREQ and RESO NANCE combine to control the tone color of the sound passing through the VCF VCF Filter Mode This switch changes the roll off character istics of the VCF either 12dB OCT or 24dB OCT and controls the envelope modulation of the VCF M TUNE TUNES VCO S RESONANCE If a foot volume pedal Roland FV 20 sold separately
