Realtime Sound-manipulation Functions
The Memotron is capable of keeping up to three sounds at one time in its internal memory. A sound is 
called   “track”.   The   panel   offers   various   controls   to   tweak   sound-parameters   in   realtime.   These 
parameters are performance oriented and will not be stored as part of a track.
• A B C selects one of the three tracks that have been loaded into the Memotron's internal memory 
(RAM). When moving the knob, the tracks are continuously cross-faded in order to simulate the 
move of the tape heads.
• PITCH shifts the pitch 3 halftones up and 3 halftones down. This will slightly affect the maximum 
duration of a played note.
• TONE changes the sonic character with help of a passive 12 dB lowpass filter.
• HALF SPEED emulates halving the tape speed. The duration of a played note is increased from 8 
to 16 seconds. The playback-pitch will be lowered by one octave. HALF SPEED also emulates a 
slight reduction of the audio quality, especially in higher frequency ranges.
• VOLUME adjusts the master volume.
