Chapter 6: Gate Control Functions

20 Operator Manual
The advantage of generating the effect in this way is that it is much more
straightforward to set up and has the added benefit that the attack control operates to
change the sonic character of the accent as well as the gate. This allows a more precise
tailoring of the sound produced — changing from tight and snappy to more of a low-end
thud as you increase the attack time.
Another important feature of the transient accent is that it is independent of the range
control, so that it is possible to accent things without gating them at all. This means
that there is no need to lose any of the original sound, while gaining extra definition and
punch.
Intelligent threshold shift (i-TS)
Intelligent threshold shift (i-TS) — or hysteresis — operates in conjunction with the
HOLD control knob to reduce chattering within the gate. Chattering is the undesirable
condition that occurs when signals — especially low frequency ones — are very close to
the gate threshold. In this situation the gate can become indecisive and repeatedly
open and shut on the programme. i-TS ensures that the gate remains open by
automatically adjusting the threshold downwards as the signal goes over threshold.
When the signal actually falls below threshold (that is, the temporarily adjusted
threshold) the i-TS resets, ready for the next gate opening. This improved
decision-making ensures that gating is rock solid and attacks start instantly and
consistently, even on signals that go slightly over threshold.
i-TS is particularly useful for low frequency material and instruments with oscillating or
unpredictable decay envelopes.
