500 SERIES - ANALOG DELAY
MOOG 500 SERIES ANALOG DELAY Thank you for purchasing the Moog 500 Series Analog Delay - the world’s first delay designed exclusively for the 500 Series format. The Analog Delay features 800ms of the warmest, and most musical analog delay on the planet, an all-analog signal path, and a LFO capable of modulating Delay Time for a wide array of modulated delay line effects including chorus, pitch shifting, vibrato, and tape delay.
TERMINOLOGY The term Delay Line refers only to the Bucket Brigade Devices (BBDs) and analog signal processing between the input and output stages. Delay and Analog Delay refer to the entire 500 Series Module. gain staging Unlike digital delays, pushing the Analog Delay into overdrive is a very musically useful effect. When the LEVEL LED flashes Orange, built-in limiters are activated.
FRONT PANEL DRIVE: Sets the input sensitivity of the Analog Delay providing a 30dB range of adjustment for optimum signal path, level matching, or overdriven sounds. LEVEL LED: Works in conjunction with the DRIVE control. Red indicates clipping (this can be used for adding color). Orange flashes indicate the start of limiting. Green indicates the presence of signal at or below the nominal level.
FRONT PANEL continued TIME RANGE : Selects between short (0.5x) and long (1.0x) delay times. Switching from 0.5x to 1.0x will lower the sound in the “feedback loop” one octave, while switching the other direction will double the pitch and time of sound in the Delay Line. This control also selects between Bright (0.5x) and Dark (1.0x) filter settings. Since the Delay’s internal antialias filter must change with the Delay Time, the 0.5x setting yields a brighter tone for the same delay time as 1.0x.
DELAY LINE CONTROL – VIA EDITOR The editor provides additional “under the hood” control of the Delay Line. For controls that are available on both the front panel and the editor, settings made using the editor (or via MIDI) will take priority over front panel settings. Adjusting a front panel control will re-establish priority until another editor or MIDI message supersedes it.
SLEW RATE: Sets the speed at which the DELAY TIME transitions from a prior setting to a new one when changing delay time via LFO or directly. MIDI CC#: MSB-5, LSB-37 MULTIPLIER: Depending on DELAY TIME and TIME RANGE settings, the MULTIPLIER enables longer DELAY TIMES. Some settings can result in “illegal” delay times causing aliasing and other audio artifacts. MIDI CC# - 75 CLOCK DIVISION: Sets Delay CLOCK DIVISIONS to a defined number of beats at the MIDI tempo (Only used when synced to MIDI.
LFO RATE: Adjusts the LFO RATE (and Clock Divisions when synced to MIDI) from 0.05 Hz to 50 Hz. MIDI CC#: MSB-15, LSB-47 LFO SHAPE: Selects from Sine, Triangle, Square, Ramp, Sawtooth, Sample and Hold, and Smooth Sample and Hold modulations as well as OFF (no LFO). MIDI CC#: 17 SYNC: When SYNC is on, the LFO RATE is linked to MIDI clock and can be set to a CLOCK DIVISION of the current MIDI BPM. MIDI CC#: 78 LFO AMOUNT: Determines the amount of LFO modulation of the Delay TIME.
Sample and Hold: Also known as a random step, a square-ish wave that randomly changes its an up and down state, and wave height. Slewed Sample and Hold (Smooth): Transitions smoothly between the Sample and Hold steps TAP/CV INPUT ASSIGNMENT The editor contains controls for configuring the TAP/CV INPUT.
midi keyboard control The editor contains controls for setting MIDI keyboard parameters. The following section details the editor’s MIDI keyboard controls and their MIDI mappings. NOTE NUMBER-> DELAY TIME: When engaged, MIDI notes sent to the Analog Delay will adjust the delay time to pitch bend the delayed audio by the musical ratio corresponding to the semitones between the notes. MIDI CC#: 82 NOTE ON-> LFO RESET: When engaged, each MIDI note ON message restarts the LFO cycle.
KNOB BEHAVIOR: Selects between vertical and rotary knob scrolling. MIDI PORT WARNING: Activates a warning when a MIDI port is unreachable. LFO THEORY OF OPERATIONS DELAY TIME AND PITCH SHIFTING When you adjust the DELAY TIME control of the Analog Delay you are actually changing the clock rate of an oscillator that determines how fast signals go through the individual circuits in the Bucket Brigade Devices.
EXAMPLES CHORUS EFFECT With the DELAY TIME at a short setting, MIX at 12:00, the LFO settings smoothly modulate the DELAY TIME so that the delayed signal has its pitch slightly raised and lowered, creating a chorus effect. BOUNCE OCTAVE PITCH SHIFT With Delay Line settings as in the previous example, these LFO settings modulate the DELAY TIME so that the delayed signal has its pitch shifted up and down by an octave.
TAP/CV INPUT TAP TEMPO The TAP TEMPO input on the Analog Delay can be used to control either the DELAY TIME or the LFO RATE. Set a tempo: Simply plug in a Moog FS-1 footswitch and tap at the desired tempo in quarter notes. After the third tap the Delay will begin calculating the tempo and keep the average tempo as you continue to tap. Set a new tempo: Wait five seconds and then press the switch three times to set a new tempo.
LFO AMOUNT: A setting of 0 volts or GROUND sets the LFO AMOUNT at zero while a 5v setting sets the AMOUNT to maximum. To modify the LFO AMOUNT from minimum to maximum via control voltage or expression pedal, set the LFO AMOUNT control to the lowest setting via the editor or MIDI message. LFO SHAPE: A setting of 0 volts or GROUND sets LFO SHAPE to OFF while a 5v setting sets SHAPE to Smooth S-H.
CIRCUIT CONFIGURATION The figure below is a simplified block diagram of the Analog Delay. MIDI CONTROL OF THE ANALOG DELAY The following section explains the MIDI implementation of the Analog Delay. For information about what MIDI is and how it works, you can go to the following webpage for tutorials: www.midi.org/aboutmidi/tutorials.php MIDI CHANNEL The default MIDI Channel for the Analog Delay is Channel 1. To change this, send the MIDI channel you wish to change to CC 119 on the existing channel.
MIDI CONTROL CHANGE (CC) MESSAGES The settings of the Analog Delay can be controlled by MIDI Control Change (CC) messages. In addition to the front panel controls, there are a number of advanced features that can be enabled and edited with Control Change messages. A MIDI CC message has both a CC# from 0 to 127 and a value from 0-127. The CC values that affect panel controls replace the physical setting of the front panel controls.
PARAMETER MSB LSB TYPE CC# CC# VALUES PERSISTENT LFO Sync on/off 78 Discrete [2] 0(off), 64(on) LFO Clock Div. 79 Discrete [21] See MIDI Clock Division Chart Pitch Bend Amt.
The DELAY TIME MULTIPLIER multiplies the delay time by 2, 4 or 8, vastly extending delay time. This feature is for obtaining unusual and lo-fi echo effects. When the delay time is increased past the default maximum delay time available on the front panel, the BBD Clock signal will be audible.
MIDI CLOCK SYNC: The DELAY TIME and LFO RATE can be synchronized to MIDI System Real-time Clock messages. These messages are 24 ppq. To enable sending of these messages, consult the user manual for your MIDI device. When the Analog Delay receives MIDI Clock messages, the LED indicator for the synchronized function turns orange to indicate that it is synchronized to MIDI Clock.
