1
A classic subtractive synth/sampler design:
None of the other answers are correct
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
2
A basic Iris 2 Patch can be made up of:
a sample keymap of 1 audio sample for each note, up to a maximum of 88 samples (full piano range)
either a keymap of up to 88 individual samples, or a group of up to 4 periodic oscillator (OSC) waves
up to 5 Sample Pools, containing audio Samples or periodic oscillator (OSC) waves
up to 4 Sample Pools, containing audio Samples or periodic oscillator (OSC) waves
3
Iris 2 features:
4 Envelopes and 4 LFOs
5 Envelopes and 4 LFOs
4 Envelopes and 3 LFOs
5 Envelopes and 5 LFOs
4
Modulators in Iris 2:
can only be assigned to one parameter at a time
can be assigned to control various parameters by dragging one's icon to, or right-clicking on, a Mod destination circle
are all pre-assigned to the most useful parameter for each Modulator, making Iris 2 especaially user-friendly
None of the other answers are correct
5
Radius RT:
is a Time-Shifting algorithm that speeds up & slows down the audio wave while preventing pitch transposition
All answers are correct
is a Timbre-Shifting algorithm that deliberately alter the tone of a wave as it's being transposed
is a Pitch-Shifting algorithm that preserves the speed of any time-based aspects of an audio wave as it's being transposed
6
Each Iris 2 Patch:
can have its own unique set of Sample and Global Filter settings, but all Patches share standard Modulation routings
can have its own unique set of Samples, Global Filter settings, and Modulation routings
None of the other answers are correct
can have its own unique set of Samples and Modulation routings, but all Patches share Global Filter and Amp settings
7
The Spectral Filter's Spectogram area:
can show the wave as both a traditional waveform display (amplitude vs time) and a spectrogram (frequency vs. time)
can display the audio wave's individual harmonics & overtones as editable horizontal white bars
can be used to loop the audio wave as well as alter its harmonic & overtone content
All answers are correct
8
Radius RT:
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
is a CPU-intensive feature, and so its use is restricted to one note at a time (monophonic patches)
is a CPU-effiecient feature, so there are no transposition-range or polyphony restrictions in its use
9
Iris 2's Spectral Filter:
None of the other answers are correct
can make static (frequency-based) changes to the harmonic content of a wave, but not time-based changes
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
10
Iris 2's MIDI Assign feature:
lets you make up to four MIDI Assignments, using only MIDI Velocity, Modwheel, Aftertouch, & Key Tracking
lets you make per-Patch MIDI Assignments to Parameters, which are different for each Patch
lets you make Global MIDI Assignments to Parameters, which do not change from Patch to Patch
None of the other answers are correct
11
What should you use to add periodic variation to static notes when programming a synthesizer?
An Oscillator
An Envelope
Spectral filtering
An LFO
12
The layout of Iris 2:
is basically a subtractive synth/sampler architecture, with the addition of special filtering, pitch-shifting, and modulation options
is too complex to describe in one sentence
is the same as any sampler, with an unlimited pool of multi-samples as its sound source
contains only the classic components of analog synths: periodic oscillators, lowpass filter, and amplifier
13
Which tool will automatically select similar harmonic content?
Magic Wand Tool
Paintbrush Tool
Lasso Tool
Frequency Selection Tool
14
Iris 2's Spectral Filter:
includes several simulations of different filter circuit types
includes selection tools familiar from graphic/photo editing sftware, like a Brush tool and Lasso tool
None of the other answers are correct
includes controls familiar from traditional audio filters, like Cutoff Frequency and Resonance
15
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 the parameter knob and choose a modulation source from the contextual menu
Right-click on one of the three modulation circles and choose a modulation source from the contextual menu
16
An Iris 2 Patch:
can use the same sample in more than one Pool, with different Spectral Filter selections/settings for each Pool
can use the same sample in more than one Pool, but they all must share the same Spectral Filter selections/settings
can only use a sample in one Pool at a time, in an individual Patch
None other other answers are correct
17
______ can be used to eliminate any dead space at the beginning of a sample.
Delay
Spectral filtering
Crossfade
Offset
18
How many samples can you layer in a patch in Iris 2?
Two
Three
Four
Five
19
Signal flow in Iris 2 is based on the traditional layout of subtractive synthesis design. True or false?
True
False
20
Iris 2's Sound Source:
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
is comprised exclusively of custom-designed digital waveshapes
21
Iris 2's Envelopes & LFOs:
consist of preset shapes, designed to complement the specific waves & samples in the Iris 2 Factory Library
None of the other answers are correct
can be freely assigned to any function that can be modulated
have fixed assignments to the classic modulation targets: filter, amp, and pitch
22
Which distortion type will give you a lo-fi/bit-crusher type of effect?
Scream
Aliasing
Clipping
Asymmetrical
23
The four Effects in Iris 2:
All answers are correct
are all preset-only, there are no user-adjustable parameters
can only be applied to the Master output, not individually to the 4 Sample Pools
are Distortion, Chorus, Delay, and Reverb
24
Iris 2's 8 Macro knobs:
can be Globally Assigned to MIDI controllers, but have different Parameter assignments for each Patch
can each be assigned to control multiple Parameters, but the Parameter assignments do not change from Patch to Patch
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
25
In an Iris 2 Patch:
each Sample Pool can have its own individual Effects mix, but all Pools share the same 4 Effects settings
each sample can be set to play in its own individual pitch range on the keyboard, or they can be layered (overlap)
All answers are correct
each Sample Pool can be set up to have its own LFO Modulation and Envelope
