"A demonstration that goes through every single function of the Tyme Sefari and the optional "A Sound Of Thunder" expansion module. The ASOT is a circuit-bending expansion that connects to the Tyme Sefari via a ribbon cable on the back of both units. Nobody except its creator knows exactly what is going on with each bend. Just buy the damn thing. It's only 45 bucks! And it'll even wash your old worn-out EconoChrist T-shirts for you."

"Tyme Sefari is a voltage-controlled sampler/delay/looper/audio buffer developed completely in-house by The Harvestman.

Using an 8-bit microcontroller and 32kB of SRAM (no prefab delay chips here), Tyme Sefari allows you to circularly record an 8-bit audio sample, with voltage control of sampling frequency. The analog front-end of the module has a wet/dry mix control as well as a feedback attenuator (with selectable polarity).

You may optionally set two loop markers within the greater recording. When enabled, the record and playback travel will only take place between these markers. When the loop points are "inside out", interesting distortions of the buffer contents occur when the marker controls are swept. Both marker controls are manual and voltage-controllable.

The transport controls of the Tyme Sefari allow you to control recording, record/playback reverse, loop enable, and playback (when toggled, this control restarts playback from the beginning of the recording or loop for easy one-shot sampling.) All four of these controls can be controlled by external gate voltages in addition to the panel switches.

The Tyme Sefari is expandable with a series of switches for "circuit bending" the behavior of the module, model 1973A "sound of thunder". These switches short out parts of the data and address busses, resulting in effects just like a modified Casio SK-1. The glue logic within the Tyme Sefari is laid out in a similar way to the SK-1, so the changes in sound are quite similar. However, the front-panel operation of Tyme Sefari remains predictable when the expansion is active."
