What is bit rate/depth/range?
Resolution of waveform. (up and down)
What is sampling rate?
Left and right of waveform (how many samples per second?)
What sampling rate and bit range/depth should you use when bouncing to disk to make a CD?
44.1k for cds
16 bit
What is a sequencer?
Program that records, edits, plays back midi. Protools - instrument track
How many ticks per quarter note on ProTools?

Name 11 things to check if not getting MIDI through the computer to an external Sound Module.
Good to post on wall - see page 54 in reader
1) Controller set to MIDI (not Local)
2) MIDI cable from the Controller (keyboard) connected to the correct input of the MIDI
Interface (Output connected to Input)
- MIDI INTERFACE
3) USB Cable connected from the MIDI Interface to the Computer
4) Correct Devices patched correctly in MIDI STUDIO SETUP
5) Correct Keyboard Controller checked in INPUT DEVICES (under the SETUP:MIDI
menu in ProTools)
6) OUTPUT set to the correct Sound Module (and correct MIDI Channel) on your MIDI
TRACK.
7) INPUT in ProTools set correctly (normally to ALL – but check to make sure the
correct Controller (Keyboard) is showing up here.
8) Record Ready on
- METERS IN PROTOOLS
9) MIDI cable connected from the MIDI Interface Output to the Sound Module MIDI IN
- MIDI MESSAGE LIGHT
10) Voices in the Sound Module set to the correct MIDI Channel and turned on
11) Audio Output cables from Sound Module connected to Mixing Board or to AUDIO
INTERFACE (Going into AUDIO CHANNEL set to INPUT) correctly.
- HEARING SOUND
Most common problem (not in reader)
MIDI quits working - restart protools (sometimes entire computer)
What are the three lights to check if not getting MIDI on external sound module?
Midi message light
Meters
Midi interface input light
What are the two main functions of MIDI STUDIO SETUP?
- Get midi through computer into protools
- Loads names of sound patches
What are MIDI channels used for?
Send/receive multiple signals to multiple sound modules
What is quantization?
Setting sound to nearest beat
If ProTools hesitates or won’t go into Record what is the most common problem?
Wait for note - Waiting for keyboard input - CMD 1 (keypad) - midi wave note (bottom right, far left button of the set)
Hesitation - count off is on (silent)
Shortcut for stopping a stuck MIDI Note
CTL-SHIFT-.
