SUNADAMALA DIGITAL LEHRA
OPERATION MANUAL
The new compact "Sunadamala" is a sophisticated electronic lehera instrument catering
to the needs of classical tabla artistes. The instrument produces 202 leheras (rhythmic
tunes) set to different Taals and Raags which can be selected by the user through the
keyboard. The instrument utilizes the latest state-of-the-art microprocessor technology to
produce a realistic sound of the lehera as played on a harmonium.
The instrument has facility to control the volume of the sound, the base pitch (sur) and
the tempo of the tune. A built-in drone is also provided, the volume of which can be
independently controlled. The "Sunadamala" can also be repeatedly programmed by the
user to play and store two leheras of his/ her composition. The instrument automatically
operates on any voltage between 90 - 260 V AC or a set of four internal dry batteries (C
size).
The special features of the improved compact model are:
1. 202 preset tunes including special "Masitkhani" and "gayaki ang" tunes. 2. Digital
display of matras, tempo, tune number & pitch. 3. Accurate built-in digital pitch-pipe with
fine tuning facility. 4. Four harmonium tones selectable by the user.
5. Memory facility for two user programmed leheras, pitch, tempo and tone selections. 6.
Can also be used as an excellent sur-peti (drone). 7. Built-in metronome. A three digit
display provides the following indications :
a. The currently selected tune number when the tune is not being played. b. The
rhythmic count (matra) when the tune is being played. c. The Tempo setting when the
FAST or SLOW keys are pressed. d. The Pitch setting (C, C#, D, etc) when the pitch
keys are pressed.
VOLUME CONTROL : Controls the combined volume of the lehera and the drone (sur
background). ALT :- Selects alternate function of each key. Also operates as the decimal
key for tune selection. PGM :- Puts the instrument into the programming mode in which
user's own lehera can be composed. NUMBER KEYS :- Used for selecting the tune
number corresponding to any taal or for programming a lehera. DRONE CONTROL :-
Controls the volume of the drone relative to the lehera.
PITCH :- Increases ('up' arrow ) or decreases ('down' arrow ) the pitch (sur) of the
instrument. FAST/SLOW : Increases or decreases the tempo of the lehera. Use of these
keys while the lehera is playing results in increase/ decrease of the tempo in small
steps. Use of these keys when the lehera is not playing results in the tempo changing to
double/ half of the previous setting. STOP :- Stops the lehera. START : Starts the lehera
from the first matra.
