1
What should you use to add periodic variation to static notes when programming a synthesizer?
An LFO
An Oscillator
An Envelope
Spectral filtering
2
Iris 2's global Filter:
is a multi-mode Filter, with lowpass, highpass, bandpass, and peak options, modeled after various filter circuit types
None of the other answers are correct
is a simple, traditional lowpass-only filter, to avoid over-processing the complex waves in the Factory Library
can only be applied to Sound Sources made up of oscillator ( OSC) waves, not audio waves (samples)
3
Radius RT:
is a Timbre-Shifting algorithm that deliberately alter the tone of a wave as it's being transposed
All answers are correct
is a Time-Shifting algorithm that speeds up & slows down the audio wave while preventing pitch transposition
is a Pitch-Shifting algorithm that preserves the speed of any time-based aspects of an audio wave as it's being transposed
4
In an Iris 2 Patch:
each sample can be set to play in its own individual pitch range on the keyboard, or they can be layered (overlap)
each Sample Pool can be set up to have its own LFO Modulation and Envelope
each Sample Pool can have its own individual Effects mix, but all Pools share the same 4 Effects settings
All answers are correct
5
Signal flow in Iris 2 is based on the traditional layout of subtractive synthesis design. True or false?
True
False
6
Iris 2's Keyboard Panel:
lets you map the 4 Sample Pools across the keyboard: layered, split, or as a sample keymap
is only available as a display, it has no user-addressable functions
is only for the purpose of mapping, it does not display incoming MIDI notes or controller information
lets you map the 5 Sample Pools across the keyboard: layered, split, or as a sample keymap
7
Iris 2's Spectral Filter:
None of the other answers are correct
allows you to make changes to the tone of an audio wave by drawing on the wave's Spectrogram display
works like a lowpass or highpass filter-you can alter the sound only above or below a certain frequency
can make static (frequency-based) changes to the harmonic content of a wave, but not time-based changes
8
The Spectrogram view shows Amplitude and Time on a X/Y axis. True or false?
True
False
9
Iris 2's Spectral Filter:
None of the other answers are correct
includes several simulations of different filter circuit types
includes controls familiar from traditional audio filters, like Cutoff Frequency and Resonance
includes selection tools familiar from graphic/photo editing sftware, like a Brush tool and Lasso tool
10
Iris 2's Sound Source:
is comprised exclusively of custom-designed digital waveshapes
All answers are correct
cannot use any samples or waves outside of the ones in the Factory Library
is comprised of up to 4 sample "Pools" of audio waves or oscillator tones
11
The layout of Iris 2:
is too complex to describe in one sentence
is basically a subtractive synth/sampler architecture, with the addition of special filtering, pitch-shifting, and modulation options
contains only the classic components of analog synths: periodic oscillators, lowpass filter, and amplifier
is the same as any sampler, with an unlimited pool of multi-samples as its sound source
12
Radius RT:
is a CPU-effiecient feature, so there are no transposition-range or polyphony restrictions in its use
is a CPU-intensive feature, and so its use is restricted to one note at a time (monophonic patches)
is a CPU-intensive feature, and so its use is restricted to a user-adjustable transposition range and limited polyphony
None of the other answers are correct
13
Iris 2's Factory Library folder:
can be installed on any HD, as long as you set the custom location in the Options window
contains Factory Patches and samples, and can only be installed on and accessed from the System (startup) HD
None of the other answers are correct
contains only audio samples, the Factory Patches are built in to the application/plug-in itself
14
Each Iris 2 Patch:
can have its own unique set of Samples, Global Filter settings, and Modulation routings
can have its own unique set of Samples and Modulation routings, but all Patches share Global Filter and Amp settings
can have its own unique set of Sample and Global Filter settings, but all Patches share standard Modulation routings
None of the other answers are correct
15
Modulators in Iris 2:
can be assigned to control various parameters by dragging one's icon to, or right-clicking on, a Mod destination circle
None of the other answers are correct
can only be assigned to one parameter at a time
are all pre-assigned to the most useful parameter for each Modulator, making Iris 2 especaially user-friendly
16
Iris 2's 8 Macro knobs:
can be assigned to control only 1 Parameter each, but different assignments can be saved with each Patch
None of the other answers are correct
can each be assigned to control multiple Parameters, but the Parameter assignments do not change from Patch to Patch
can be Globally Assigned to MIDI controllers, but have different Parameter assignments for each Patch
17
How many samples can you layer in a patch in Iris 2?
Two
Five
Three
Four
18
Each modulatable parameter in Iris 2:
can accept one Modulator each
can accept an unlimited number of Modulators
can accept up to 3 Modulators, which be combined in several different ways
can accept two Modulators each
19
A classic subtractive synth/sampler design:
does not alter the tone of the sound source in any way, just subtracts volume for dynamic performance
builds up a wave from scratch, Sine wave by Sine wave
starts with a sound source rich in harmonics & overtones and filters them to shape the tone
None of the other answers are correct
20
Iris 2's Envelopes & LFOs:
can be freely assigned to any function that can be modulated
consist of preset shapes, designed to complement the specific waves & samples in the Iris 2 Factory Library
have fixed assignments to the classic modulation targets: filter, amp, and pitch
None of the other answers are correct
21
How can you assign a modulator to a parameter?
Drag the modulation source four-arrow icon to a modulation assignment circle
All answers are correct
Right-click on one of the three modulation circles and choose a modulation source from the contextual menu
Right-click on the parameter knob and choose a modulation source from the contextual menu
22
A basic Iris 2 Patch can be made up of:
up to 4 Sample Pools, containing audio Samples or periodic oscillator (OSC) waves
either a keymap of up to 88 individual samples, or a group of up to 4 periodic oscillator (OSC) waves
a sample keymap of 1 audio sample for each note, up to a maximum of 88 samples (full piano range)
up to 5 Sample Pools, containing audio Samples or periodic oscillator (OSC) waves
23
Spectral Filter selections:
can only be made in the time domian, to create stutter-edit effects
can only bemade in the Frequency domain, to alter the balance of harmonics & overtones
can be made in the Frequency or Time domain, or in both together, changing over time
None of the other answers are correct
24
The four Effects in Iris 2:
are all preset-only, there are no user-adjustable parameters
All answers are correct
are Distortion, Chorus, Delay, and Reverb
can only be applied to the Master output, not individually to the 4 Sample Pools
25
Iris 2 is:
a hybrid synth-sampler with unique spectral filter and pitch-shifting features
a basic synthesizer with a preset-only design
a knob-for-knob recreation of a classic analog hardware synthesizer
a knob-for-knob recreation of a classic digital hardware synthesizer
