The blank-preset button creates a new patch with default settings and all planets set to silent.
The random-tonal preset button creates a random patch using predominantly tonal sounds.
The random-rhythmic preset button creates a random patch using more percussive sounds.
The save button saves the current settings over the existing preset.
The save-as button saves the current settings as a new preset.
The email button sends the currently selected preset as an email attachment.
The factory/user button switches between the factory and user preset lists.
Press the record button to start and stop recording. AIFF files are saved into a "Recordings" folder and can be downloaded to your computer through iTunes file sharing.
The chaos emitter generates new particles at random locations. The amount knob controls the rate at which chaos particles are emitted.
When touch is enabled, touching the screen generates new particles. Particles can be launched in any direction with a swipe gesture. The rate knob controls the particle spawning rate.
When satellite is enabled, the satellite constantly fires particles in a single direction. The power knob controls the particle velocity. The angle knob controls the direction of the satellite. The firing rate knob controls the rate at which particles are fired.
The satellite can be moved by dragging it in the main view. Also, its angle and power can be controlled with a second finger.
The beat-sync button enables quantization. Notes generated by particle impact will be delayed until the next subdivision value of the planet generating them.
The tap-tempo button allows the tempo to be set by tapping at the desired rate.
The tempo knob allows the tempo to be set manually.
The master mute stops all planets from playing new notes and allows currently playing notes to decay naturally.
Time warp controls the speed of the entire solar system with a single knob.
Master volume controls the overall gain of the synthesis engine. Lower this if clipping occurs.
The low-pass button enables and disables the low-pass filter. Frequencies below the cutoff frequency will be filtered out. Resonance amplifies frequencies near the cutoff freqency and should be used with caution.
The high-pass button enables and disables the high-pass filter. Frequencies above the cutoff frequency will be filtered out. Resonance amplifies frequencies near the cutoff freqency and should be used with caution.
This is a standard chorus effect. The button activates and deactivates the effect. Rate controls the average delay length for the chorus. Depth controls the amplitude of the modulation of the delay lines. Mix controls the wet/dry mix between the chorus and non-chorus outputs.
SpaceWiz also includes an adjustable delay. The time knob controls the length of the delay line. The feedback knob controls how much the signal is attenuated each pass through the delay. The mix knob controls the wet/dry mix between the signal with the delay effect and the signal without the delay effect.
The reverb effect is a high-quality convolution reverb with a variety of types. The size knob controls the speed of early reflections. The mix knob controls the wet/dry mix between the signal with the reverb effect and the signal without the reverb effect.
The planet number buttons are used to select which planet is active for editing.
The planet mute and solo buttons are used to mute or solo the corresponding planets.
The upper control is the bank select, and it changes the bank of sounds. The lower control selects the sound within the bank.
The low-note knob sets the lowest note that a planet is allowed to play. This is set automatically when changing sounds.
The high-note knob sets the highest note that a planet is allowed to play. This is also set automatically when changing sounds.
The voices knob sets the maximum number of simultaneous voices (polyphony) for the selected planet. Once the limit has been reached, no new sounds will occur until a voice has finished playing.
The volume knob controls the volume for future notes for the planet.
When the auto-pan control is enabled, the planet's position in the stereo field corresponds to its position in space.
When auto-pan is disabled, manual panning allows the planet's sound to be positioned precisely in the stereo field.
The pitch mode chooses how notes are determined when particles impact planets. The angle selection maps location of impact on the planet to pitch. The x-position selection maps the horizontal location of the planet to pitch, and the y-position selection maps the vertical location of the planet to pitch.
MIDI output is available as a bank selection on the planet view. When MIDI out is the selected bank, the bottom row chooses the MIDI output channel.
When MIDI output is active, the voices knob changes to a duration knob. This controls the duration of the MIDI notes that are output.
When the in-key button is enabled, MIDI notes conform to the current tonality settings.
The MIDI velocity curve knob determines the shape of the velocity curve applied to all MIDI notes.
The quantization selection determines the time interval on which the quantization grid is based. Quantization can be set to the nearest sixteenth note, eighth note, quarter note, half note, or whole note.
The override-tonality button forces a planet to override the current tonality and play only the notes specified on the keyboard.
The intervallic button causes the override notes to be treated as intervals relative to C.
The orbit-rate knob controls the speed at which the planet orbits the sun.
The orbit-width knob controls the width of the orbital ellipse.
The orbit-height knob controls the height of the orbital ellipse.
The randomize button randomizes all parameters for the selected planet.
The mass knob controls the size and gravitational pull of the selected planet.
The bounce knob controls how high particles bounce when striking the planet. If set to zero, the particle is destroyed upon initial impact.
The power button enables and disables the synthesizer. Turning the synthesizer off while not in use increases battery life and performance. The synthesizer is playable on the keyboard in the synth view or by touching the solar system in any other view.
The synthesizer volume knob controls the gain of the synthesizer.
The randomize button generates random values for all synthesizer parameters. If the synth seems silent after randomizing, check the attack times and the cutoff frequency.
Oscillator 1 has controls for wave type and level (amplitude).
Oscillator 2 also has controls for wave type and level (amplitude). In addition, the sync button will sync the phase of oscillator 2 to that of oscillator 1, and the frequency knob sets the frequency of oscillator 2 relative to that of oscillator 1.
A standard ADSR envelope is provided for the volume of the synth. The attack knob sets the amount of time that the synth takes to reach maximum volume when a note is pressed. The decay knob sets the amount of time from the end of the note attack to when the note reaches its sustain level. The sustain knob sets the sustain level that is reached at the end of the decay portion of the envelope. The release knob sets the amount of time for the volume to drop from the sustain level to silence when a note is released.
An ADSR envelope is also provided for the synth's low-pass filter. The attack knob controls the amount of time that it takes the filter to reach the designated cutoff frequency. The decay knob controls the amount of time the filter takes to drop the cutoff frequency from its maximum value to its sustain value. The sustain knob controls the cutoff frequency that is reached at the end of the decay portion of the envelope. The release knob controls the amount of time that the filter takes to move the cutoff frequency from the sustain value to 0 Hz when a note is released.
The low-pass filter has three adjustments. The cutoff knob sets the filter's cutoff frequency. The resonance knob sets the resonant peak of the filter. When enabled, the y-axis button links the filter's cutoff frequency to the vertical touch position.
The low-note knob sets the lowest note in the synthesizer's range.
The high-note knob sets the highest note in the synthesizer's range.
The synthesizer includes a chorus effect. The button activates and deactivates the effect. Rate controls the average delay length for the chorus. Depth controls the amplitude of the modulation of the delay lines. Mix controls the wet/dry mix between the chorus and non-chorus outputs.
The synthesizer also includes a delay effect. The time knob controls the length of the delay line. The feedback knob controls how much the signal is attenuated each pass through the delay. The mix knob controls the wet/dry mix between the signal with the delay effect and the signal without the delay effect.
By default, knobs work by rotating in a circular fashion. In most cases, this allows a finer level of control. When vertical knob control is active, knobs work by dragging up and down.
When active, all particles are cleared when pausing and resuming using the play button.
When active, randomizers will not change the master tonality or a planet's override settings.
