Introduction congratulations on your purchase of a yamaha spx90ii digital multi- effect processor. The spx90ii is an amalgam of advanced acoustical research and digital technology designed to provide musicians and home recording enthusiasts with a wide range of exciting effects. The spx90ii digital ...
Page 3: Precautions
Precautions note: it is vital to read this section before using your spx90 ii digital multi-effect processor. This unit utilizes state-of-the-art digital technology which, although designed to provide years of trouble-free use, required careful handling. Voltage ratings be sure the ac supply in your...

Front panel power on/off switch when the power is turned on, the program which was selected immediately before the power was turned off will be re-selected. Due to the safety muting circuit, no sound will be produced by the spx90 ii for a few seconds after the power is turned on. Input level control...
Page 5: Rear Panel
Rear panel remote control connector permits remote access to spx90 ii effect programs. The optional remote control unit, model rc7, per- mits direct access to programs 1 through 7 and 31 through 37, while all other preset programs may be accessed sequentially. U.S. & canadian models midi thru connec...
Page 6: Basic Operations
Basic operations before actually selecting or editing programs on your spx90 ii, make sure that all connections have been made properly, and that the input level switch, output level switch, and input level control have been properly set according to the source signal and equipment to which the spx9...

3. Use parameter increment/decrement keys to set desired value of the selected parameter. Note: a description of each parameter and its effect will be given in the programmable para- meters section, beginning on page 10. Store: saving edited programs once you’ve edited parameters on a preset program...

Utility functions the utility key provides access to four utility func- tions. These functions are selected in the following se- quence each time the utility key is pressed: normal mod edit title midl control mldl program change footswitch memory recall normal mode. The utility key led will light du...

Midi bank and channel programming when this function is called, the lcd will appear as f o l l o w s : use the parameter increment/decrement keys to select the desired bank, and the memory incre- ment/decrement keys to select the desired midi channel number for that bank. When “ch = omni” is selecte...

Description of programs and parameters the preset programs in the spx90 ii fall into the following types: rev (reverb), er1 and er2 (early reflections), delay, echo, mod (modulation), gate, pitch, freeze, pan, vibrato and peq (parametric equalizer): each of these program types has a specific selecti...

This effect, commonly used in contemporary record- ings, produces independently variable left-and right- channel signal delays. The result is an intriguing “doubl- ed” sound. 1. Left channel delay time. Range: 0.1 ~ 2000.0 msec permits highly accurate setting of the left channel delay following the ...

Stereo flange a combination of delay and lfo (low frequency oscillation) modulation, the popular flanging effect can dramatically thicken the sound of keyboard in- struments, or produce the “aircraft” sound popular among guitarists. Basically, a short delay time is varied with lfo modulation so that...

Stereo phasing the spx90 ii can produce a wide range of phasing ef- fects from a barely perceptible shift to a rapid pulsa- tion. Phasing lends an animated quality to musical in- strument and vocal recordings: this effect has the same parameters as stereo flange, except that the delay time range is ...

Tion of the pitch change program. For example, if base key = c4, then pressing the c3 key on the synthesizer keyboard will set the pitch change value to — 12 (one octave down). Pressing d4 on the keyboard would produce a pitch increase of one tone (+ 2). If a key more than one octave higher or lower...

Triggering manual mode to actually begin recording if the manual mode has been selected, press the parameter in- crement key. The spx90 ii will record for 2,000 milliseconds. Also the optional foot switch fc-5 can be used. Connect the fc-5 to the memory/trigger foot switch jack and press the foot tr...

This program feeds the reverb signal through a gate cir- cuit, making it possible to output only a segment of a longer reverb sound. Parameters provided for the reverb porition of the signal are rev time, high, delay, hpf and lpf, while parameters for the gate portion are hold time, release time, an...

6. Decay level. Range: 0 ~ 100% determines the level at which the gate remains open for the hold time. The lower the value the lower the hold gate level. 7. Hold time. Range: 1 msec ~ 30,000 msec determines how long the gate stays open, allowing the input signal to pass. 8. Release time. Range: 5 ms...

This program makes it possible to add delay vibrato ef- fects to virtually any instrument or sound. When the input signal exceeds a programmed trigger level, the vibrato effect is cancelled and then gradually builds up to the programmed depth. 1. Trigger level. Range: 1 ~ 100% determines the input s...

Recording system in a recording system it is most desirable to have the spx90 ii input and outputs available at a patch bay where they may accessed and patched into virtually any part of the system. In some cases it might be best to have the spx90 ii connected directly in line between the source and...
