ATTACK is the rate at which the GATE opens from the RANGE setting. Too
ATACK
fast an attack coupled with too high a threshold will cause 'clicks' (square
edges) onto low-frequency programme material. The fastest attack setting
is
3µS 3µS, the slowest being 10S 10Seconds
HOLD is the time GATE remains open, after any Peak Envelope has
HOLD
finished. The minimum HOLD time is 8mS 8mS and the maximum is
20S 20Seconds. HOLD also effects the note-on length if the MIDI GATE SEND
is enabled.
DECAY is the rate at which gate closes once the HOLD time has elapsed.
DECAY
The fastest decay rate is 2mS 2mS, the slowest being 10S 10Seconds.
RANGE is the maximum amount of Gain Reduction applied when the gate
RANGE
is closed. Normally this will be the maximum of -90dB -90dB. If the RANGE is set
to nothing, ie. 0dB 0dB, MIDI notes will still be sent when the GATE fires, and
only the PEAK envelope will affect the audio signal. This latter suggestion
can produce dynamic improvements to percussion tracks, especially if
they have been previously recorded onto tape.
These parameters will be very different when GATE TYPE is set to
RECORDED RECORDED.
GATE PARAMETERS FOR RECORDED TYPE
Sets a signal input level above which the GATE opens. The GATE
THRESH
THRESHold and the input level meter reads the level after the Filter if the
GATE
is set to IntFilter IntFilter or ExtFilter ExtFilter. The THRESHold
KeySOURCE
parameter ranges from -50dB -50dB to +18dB +18dB. Care must be taken when setting
the THRESHold and RETRIGger parameters if the complete recorded
envelope is to be replayed. Every time THRESHold is exceeded the
envelope starts to play again unless prevented by some RETRIGger time
or mask.
When the RECORDED envelope is first selected this RATE parameter will
RATE
always be the rate that the envelope was recorded initially. However this
replay time can be adjusted to fit the sound being 'gated'. The recorded
envelope facility is best optimised when a wave shape was recorded
slowly and replayed at the correct speed, similar in method to the use of
Vari-speed on a tape recorder.
The DIRection of the envelope can be as it was recorded, Fwd Fwd (forward),
DIR
or Rev Rev (reversed) for creative effects.
This is the number of the RECORDED envelope, 1 1 to 16 16. The titles will
NUM
scroll through accordingly. The envelopes shown in the section FACTORY
RECORDED GATE ENVELOPES will be available, if these have not been
over-written.
