1
An Iris 2 Patch:
can use the same sample in more than one Pool, with different Spectral Filter selections/settings for each Pool
None other other answers are correct
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
2
______ can be used to eliminate any dead space at the beginning of a sample.
Spectral filtering
Delay
Crossfade
Offset
3
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
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
None of the other answers are correct
4
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 Global MIDI Assignments to Parameters, which do not change from Patch to Patch
None of the other answers are correct
lets you make per-Patch MIDI Assignments to Parameters, which are different for each Patch
5
A basic Iris 2 Patch can be made up of:
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
a sample keymap of 1 audio sample for each note, up to a maximum of 88 samples (full piano range)
6
How can you assign a modulator to a parameter?
All answers are correct
Right-click on the parameter knob and choose a modulation source from the contextual menu
Drag the modulation source four-arrow icon to a modulation assignment circle
Right-click on one of the three modulation circles and choose a modulation source from the contextual menu
7
What should you use to add periodic variation to static notes when programming a synthesizer?
An Envelope
An LFO
Spectral filtering
An Oscillator
8
Each Iris 2 Patch:
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
can have its own unique set of Sample and Global Filter settings, but all Patches share standard Modulation routings
9
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 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
10
Spectral Filter selections:
None of the other answers are correct
can only bemade in the Frequency domain, to alter the balance of harmonics & overtones
can only be made in the time domian, to create stutter-edit effects
can be made in the Frequency or Time domain, or in both together, changing over time
11
Iris 2's Spectral Filter:
None of the other answers are correct
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
includes several simulations of different filter circuit types
12
Radius RT:
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
All answers are correct
is a Time-Shifting algorithm that speeds up & slows down the audio wave while preventing pitch transposition
13
Iris 2 is:
a basic synthesizer with a preset-only design
a knob-for-knob recreation of a classic analog hardware synthesizer
a hybrid synth-sampler with unique spectral filter and pitch-shifting features
a knob-for-knob recreation of a classic digital hardware synthesizer
14
Radius RT:
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
is a CPU-effiecient feature, so there are no transposition-range or polyphony restrictions in its use
15
Each modulatable parameter in Iris 2:
can accept one Modulator each
can accept two Modulators each
can accept up to 3 Modulators, which be combined in several different ways
can accept an unlimited number of Modulators
16
Iris 2's Sound Source:
All answers are correct
is comprised exclusively of custom-designed digital waveshapes
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
17
The Spectrogram view shows Amplitude and Time on a X/Y axis. True or false?
False
True
18
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
None of the other answers are correct
starts with a sound source rich in harmonics & overtones and filters them to shape the tone
19
The Spectral Filter's Spectogram area:
can be used to loop the audio wave as well as alter its harmonic & overtone content
can show the wave as both a traditional waveform display (amplitude vs time) and a spectrogram (frequency vs. time)
All answers are correct
can display the audio wave's individual harmonics & overtones as editable horizontal white bars
20
Signal flow in Iris 2 is based on the traditional layout of subtractive synthesis design. True or false?
False
True
21
Iris 2 features:
4 Envelopes and 3 LFOs
5 Envelopes and 5 LFOs
4 Envelopes and 4 LFOs
5 Envelopes and 4 LFOs
22
Iris 2's Factory Library folder:
contains only audio samples, the Factory Patches are built in to the application/plug-in itself
None of the other answers are correct
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
23
Iris 2's Envelopes & LFOs:
have fixed assignments to the classic modulation targets: filter, amp, and pitch
can be freely assigned to any function that can be modulated
None of the other answers are correct
consist of preset shapes, designed to complement the specific waves & samples in the Iris 2 Factory Library
24
Which tool will automatically select similar harmonic content?
Lasso Tool
Paintbrush Tool
Frequency Selection Tool
Magic Wand Tool
25
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
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
