OTO - BAM

Space Generator is the BAM's byname, a stereo reverb effect which is inspired by the digital reverb units of the late 70s / early 80s. It simlulates the algorithms, frequency spectra and artefacts of those units being responsible for their specific sound, yet being a modern device it offers MIDI control, seven algorithms, analog filters and memory - all that in a form factor of a small desktop effect.

The direct parameters of the BAM are controlled with the potentiometers:

• Size: size of the reverb room
• Pre-Delay: determines the time between the original signal and the early reflections. Maximum 500ms with potentiometer and 1500ms wwith TAP
• Mix: blends over from the original signal to effect signal
• Reverb Time: well, time of the reverb
• Damping: cuts the high frequencies of the the effect signal

The buttons at the bottom of the unit are used for adjusting further parameters in comjunction with the Data control:

• Type: selects one of seven carefully programmed algorithms: Room, Hall, Plate, Ambient, Chorus, Non-Linear and Primitive
• In Gain: determines volume of input and it adds distortion through analog clipping in the range of 0dB to +15dB
• Filters: steps through two filtre types and a number of fixed cutoff frequencies:
  • Low-Cut Filter: 20Hz, 80Hz, 150Hz, 250Hz, 450Hz
  • Hi-Cut Filter: 1.8kHz, 4.5kHz, 7kHz, 9kHz, 15kHz

More buttons for other functions:

• Active: turns the effect on or off. there are three different bypass modes: Relay, Spillover and Bypass
• Tap: Tap Tempo button, assignalble to Pre-Delay or Reverb Time
• Preset: selects through the 72 memory slots
• Chorus: adds a Chorus effect to the reverb
• Freeze: will freeze the entire frequency spectrum of the effect signal. Great for creating infinite reverb.

MIDI input: BAM responds to CCs and Program Changes.
