6.8 Release
This is a dual mode control, introducing hold as well as release. The hold time
is determined internally to be about 20% of the selected release time.
Hold
A short hold time is required to avoid the DPR 944 from starting another attack
sequence if the key signal momentarily falls below the threshold level. The
hold time is reset every time an above threshold event is detected. Therefore,
if there is never a pause in the program longer than the hold time, the gate
will never shut, helping to minimise jitter (the gate repeatedly opening and
shutting very quickly).
Release
This is the final phase of operation and is entered after the hold time has
expired. At the end of the time set with the release control, the signal will be
reduced by either 80dB or 20dB as set with the depth switch. During release,
the signal is reduced, as in figure 7.3b. This produces a very natural sounding
fade, because the normal dynamics of the signal are preserved, which is
especially important for long release times.
6.9 Stereo link
With this switch depressed, both gate channels of the DPR 944 can be made
to open simultaneously.
The key signals from both channels are added together and applied to the
controls of channel 1 for processing in the normal manner. The level control
stage for channel 2 is disconnected from the channel 2 controls and
connected instead to the control signal from channel 1. Therefore, if either
channel provides a sufficiently large key signal, both channels will open
together with the gate status being displayed on channel 1's lights.
In stereo link mode, all of the controls on channel 2 are disabled. The channel
2 key insert jack still operates, and will provide key return signal for summing
to channel 1.
The main program inputs and outputs are not connected in any way in stereo
mode, only the control signals are added together.
