This setup shows off how
long envelope times, in
relation to the pattern’s
rate, creates a morphing
timbre. Try increasing
the rate on this setup to
make for a more tremu-
lous effect.

POWER: The MF-105B works
on +9 volts DC and uses a max
of about 240 milliamperes of
current. Use only the power
supply supplied with the MF-
105B or the exact equivalent.
Power sources rated with
voltages in excess of +9 volts
may cause damage to the MF-
105B’s circuit.
PEDAL INPUTS: All pedal control input jacks are 1/4” tip-ring-
sleeve (stereo) phone jacks. The sleeves are grounded and the ring
terminals are supplied with +5 volts which is current-limited. The
tip terminals receive the variable voltages from the pedals.
