Oto machines BAM

BAM is a stereo reverb processor inspired by the late 70s / early 80s digital reverberator units.These units are sought after by sound engineers, producers and musicians for their grainy, warm and musical reverberations.

The audio signal was severely high-cut filtered (10 kHz) because of the limited sample clock. Some units used 12 bit gain stepping converters to achieve a 15 bit resolution and others used the first 16 bit converters. Then the samples were digitally processed through a 16 to 20 bit fixed-point CPU with limited memory. The algorithms had to be simple but efficient to create the most musical and versatile reverberation from these limitations. And the hardware itself added grain and warmness to the sound.

The technology used in BAM is very close to the one used in these early digital reverberator units : 16 bit converters, 20 bit fixed-point processing, analog filtering and even an input transformer transient simulator. Some of the 7 reverb algorithms are influenced by the early structures, and some are brand new.

BAM is a very musical and unique reverb processor. It combines the sound quality of a vintage reverb processor with the playability of a desktop effect in a compact format with MIDI control and 36 user presets.
