Which of the following could be used to soften the attack of a note?
1. LFO
2. Envelope generator
3. Mod wheel
4. Aftertouch
- Envelope generator
What is the primary purpose of a step sequencer?
Step sequencers trigger notes and control note values in a timed and sequential order.
In the Subtractor synthesizer, what are 2 fixed modulation routings on the control panel?
- Filter Envelope
- Amp Envelope
What is a fixed modulation modulation routing?
The source is hard-wired to the destination and it can’t be changed.
When the release time is set to 0, what are the characteristics of the ending of the note shape?
A Release time of 0 stops output immediately.
When the Attack and Decay times are set to 0, what are the characteristics of the sound shape?
When Attack and Decay times are set to 0, there is an immediate output when a note begins.
When the Decay time is increased from 0, what happens to the shape of the sound?
With a short decay time, there is a strong initial attack.
What happens to the shape of a sound when the Release time is increased?
As we set the Release time increasingly longer, the notes begin to sustain over each other, and the sound becomes blurry and muddy.
What is the one setting in an envelope that needs to be increased in an Attack/Decay envelope setting?
Decay.
What is the biggest difference between an Amp Envelope and a Filter Envleope?
Amp Envelopes always starts and ends with an output of 0.
Filter Envelopes control how far from the user-set Filter Cutoff Frequency we increase or decrease.
