EFM
The EFM MD-synth introduces Elektron’s
“Enhanced Feedback Modulation” algorithms.
The generated sound ranges from realistic
acoustic drums to wild, chaotic effects.
BASS DRUM “EFM-BD”
PTCH - Controls the basic pitch of the drum.
DEC - Controls the decay time.
RAMP - The pitch ramp depth.
RDEC - The pitch ramp decay time. A higher value gives a
longer decay.
MOD - The frequency modulation depth.
MFRQ - The modulation frequency.
MDEC - The modulation decay time.
MFB - Modulation feedback.
SNARE DRUM “EFM-SD”
PTCH - Controls the basic pitch of the drum.
DEC - Controls the decay time.
NOISE - The amount of noise in the snare drum.
NDEC - Noise decay time.
MOD - The frequency modulation depth.
MFRQ - The modulation frequency.
MDEC - The modulation decay time.
HPF - High pass filter frequency.
TOM “EFM-XT”
PTCH - Controls the basic pitch of the drum.
DEC - Controls the decay time.
RAMP - The pitch ramp depth.
RDEC - The pitch ramp decay time. A higher value gives a
longer decay.
MOD - The frequency modulation depth.
MFRQ - The modulation frequency.
MDEC - The modulation decay time.
CLIC - Adds a click to the start of the drum.
CLAP “EFM-CP”
PTCH - Controls the basic pitch of the drum.
DEC - Controls the decay time.
CLPS - The number of claps.
CDEC - The clap decay time. A higher value gives a longer
decay.
MOD - The frequency modulation depth.
MFRQ - The modulation frequency.
MDEC - The modulation decay time.
HPF - High pass filter frequency.
RIMSHOT “EFM-RS”
PTCH - Controls the basic pitch of the drum.
DEC - Controls the decay time.
MOD - The frequency modulation depth.
HPF - High pass filter frequency.
SNAR - Adds snare drum timbre to the sound.
SPTC - The pitch of the snare drum timbre.
SDEC - The decay of the snare drum timbre.
SMOD - The modulation depth of the snare drum timbre.
COWBELL “EFM-CB”
PTCH - Controls the basic pitch.
DEC - Controls the decay time.
SNAP - The amount of snap in the beginning of the sound.
FB - Feedback amount.
MOD - The frequency modulation depth.
MFRQ - The modulation frequency.
MDEC - The modulation decay time.
