Sound Sources and Effects for Scratching
Currently, this system plays prerecorded scratching sounds for each note in the
scratching phrases. It is possible to assign a single sound source and slightly change
each note in the phrase and to change the playback speed of the assigned source to
create individual effects. By using these functions, the same sound source can be
used in a phrase, although each note played is not the same. This reduces the number
of sound files and materials necessary and makes it easy to create a phrase with a few
sound sources. Even if only one sound file is assigned to all the notes of all phrases,
a wide repertoire of phrases can be realized by randomly changing playback speeds.
Although individual assignments are performed before playing with this system, the
randomizing mode can be controlled in real time using the touch inputs. This method
of sound assignment and generating effects makes the phrases seem more natural
and nonmechanical. In addition, actual DJs employ a variety of techniques on real
turntables and faders, for instance, chirp scratch, forward/backward scratch, and
transformer scratch. These functions of Bathcratch can be considered as simplified
and modified functions that are carried out using actual turntables and faders.
