FX Devices

AUDIO UNIT

BAM allows loading external Audio Unit v3 plugin effects. For information on exposing AUv3 plugin parameters for mapping, automation and modulation see the Device Rack section.

AUv3 presets are browsable in a drop-down menu in the rack panel.

BIT REDUCTION

BAM Bit Reduction FX Device

Degrade the audio bit depth, introducing audible quantization error artifacts.

  • DEPTH - Audio bit depth
  • DRY/WET - Mix between the unprocessed and processed signals

CHORUS

BAM Chorus FX device

Stereo chorus effect (it converts mono signals to stereo) with two different algorithms. The CHORUS simulates the subtle pitch and timing differences that occur when multiple musicians or vocalists play the same note, but vary slightly in pitch and timing.

  • RATE - Frequency of the modulations
  • TIME - Delay of the modulated signal
  • DEPTH - Modulation amount
  • SPREAD - Stereo image widening effect
  • FEEDBACK - Amount of signal to be fed back into the circuit
  • MODE - Switch between two different CHORUS algorithms
    • ANA - Analog
    • DIM - Dimension
  • DRY/WET - Mix between the unprocessed and processed signals

COMPRESSOR

BAM Compressor FX Device

A flexible and versatile compressor with side-chain capabilities, suitable for controlling audio transients and managing perceived loudness.

  • THRESHOLD - Level at which the compressor starts acting
  • RATIO - Gain reduction ratio applied to the input signal above the threshold
  • ATTACK - Time it takes for the gain reduction to be fully applied after the signal surpasses the threshold
  • RELEASE - Time it takes for the gain reduction to fully dissipate after the signal goes below the threshold
  • MODE - Select between feedforward and feedback compression algorithms
    • FF - The gain reduction is based on the clean input signal.
    • FB - The compressed output is fed back into the sidechain, meaning the compressor reacts to the signal after it has already been compressed. This makes the gain reduction soften over time.
  • STYLE - Control the character of the gain reduction envelopes
    • A lower value results in very fast envelopes and can result in ripples and distortion similar to a FET compressor. A higher value behaves like a cleaner VCA compressor.

Side Chain

  • SC SOURCE - Source for the compressor's analysis signal
  • SC GAIN - Input volume of the compressor's analysis signal
  • SC HP - Enable the analysis signal high-pass filter
  • SC HP CUTOFF - Cutoff frequency of the high-pass filter

Master

  • MAKEUP - Volume control of the output signal, used to rebalance the perceived loudness after the compression
  • DRY/WET - Mix between the unprocessed and processed signals

DELAY

BAM Delay FX Device

A virtual stereo tape delay. This delay has tape emulation controls, a custom filter and stereo parameters.

  • TIME - Delay time between the repetitions of the signal
  • SYNC - Synchronize the delay time to project tempo
  • FEEDBACK - Amount of the output signal fed back into the circuit
  • PING PONG - Enables ping-pong mode, where the delay bounces back and forth between the left and right channels
  • FREQUENCY - Starting point of the frequency band filtering the signal
  • BAND - Bandwidth of the frequency band
  • SPREAD - Add a delay to the right channel
  • STEREO WIDTH - Amount of pan separation between the left and right signals of the output

  • WOW - Amount of slow frequency modulation generated by the playback speed variations of a tap machine
  • DRY/WET - Mix between the unprocessed and processed signals

EQUALIZER

BAM 3-band EQ FX device

A three-band equalizer with controllable bandwidth parameters, ideal as a frequency band cut or frequency band isolator.

  • LOW - Low frequency band gain
  • MEDIUM - Medium frequency band gain
  • HIGH - High frequency band gain
  • LM CROSS - Frequency of the crossover between the low and medium frequency filters

FILTER

BAM Filter FX Device

A multi-mode filter with 6 different modes.

  • CUTOFF - Filter cutoff frequency
  • RESONANCE - Resonance or Q factor of the filter; creates a resonant peak at the cutoff frequency
  • MODE - Filter mode
    • L4P - 4 pole Low-pass Filter (24dB/oct attenuation) - A low-pass filter allows low frequency content to pass through, cutting high frequency content at a rate defined by the number of poles. This filter is a digital implementation of the Moog Transistor Ladder Filter.
    • L2P - 2 pole Low-pass Filter (12dB/oct - thus less frequency cutting effect than the L4P) - This filter is a digital implementation of an analog multi-mode filter topology in the low-pass mode.
    • B2P - 2 pole Band-pass Filter (12dB/oct) - A band-pass filter allows only a restricted frequency band to pass through, attenuating frequencies above and below. In this filter the Q factor has a particular importance as it somewhat defines the bandwidth that can pass through the filter. This filter represents the band-pass output of the analog multi-mode filter implementation.
    • H2P - 2 pole High-pass Filter (12dB/oct) - A high -pass filter allows high frequency content to pass through, attenuating low frequency content. This filter represents the high-pass output of the analog multi-mode filter implementation.
    • NOTCH - Notch Filter - A notch filter is a filter that cuts a very restricted band of frequencies. The Q factor designates how narrow the band is. Can be used to achieve a phaser-like effect, especially
      when modulating the cutoff. This filter is also a product of the multi-mode filter topology used in the other filters (except L4P).
    • PEAK - Peak Filter - A peak filter amplifies a frequency band with the resonance determining the amplification amount and creating a resonant peak at high values.

PARAMETRIC EQ

This is a parametric equalizer with low and high shelf controls and three peak filters with controllable cutoff frequency and Q factor.

L Shelf

A low shelf filter amplifies/attenuates all of the frequency content below the cutoff frequency.
