Calibrating the Trigon-6
The Trigon-6 is calibrated at the factory. Controls such as the pitch and
mod wheels shouldn’t require re-calibration. However, because its oscil-
lators and filters are voltage controlled and can be affected by extremes
of temperature, you may need to use the built-in calibration function to
tune them occasionally.
How and When to Calibrate the Oscillators and Filters
The first time you use the Trigon-6, please run its built-in oscillator and
filter calibration procedure. Let it warm up for several minutes and come
to its normal operating temperature before doing so.
Repeat the calibration procedure as needed over the next few days of
use. The Trigon-6 learns the range of temperatures at your location and
will keep itself in tune over this range.
A good rule of thumb is to cover the main temperature ranges as the
Trigon-6 heats up. Calibrate several minutes after powering on, at about
30 minutes, and at about 1 hour.
Later, if you use the Trigon-6 in a different environment that is measur-
ably warmer or cooler (on stage, in an air-conditioned studio, and so on)
run the calibration procedure again.
To calibrate the oscillators and filters:
1. Hold down the
preset
button and press 0.
2.
The front panel LEDs and display begin flashing as the Trigon-6
performs its auto-calibration procedure.
3.
When finished, the front panel controls will return to normal and you
can play the Trigon-6 again.
