From the project
Aarebot is a dynamic realtime sampler built as a Eurorack module. At its core is a stereo tape-style engine with a hot-swapping record/playback buffer - this enables to record and play simultaneously. Slicing markers can be added on the fly, and processing through an onboard effe
Aarebot is a dynamic realtime sampler built as a Eurorack module. At its core is a stereo tape-style engine with a hot-swapping record/playback buffer - this enables to record and play simultaneously. Slicing markers can be added on the fly, and processing through an onboard effects chain.
Samplerate decimation trades fidelity for buffer length. A Schroeder reverb implementation reaching from spacious room to sharp metallic resonance ringing depending on the XY effect mapping.
