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 lters 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 rst time you use the Trigon-6, please run its built-in oscillator and
lter calibration procedure. Let it warm up for several minutes to allow
the circuitry to generate some heat 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 cover the main teperature ranges as the Trigon-6
heats up - 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 (under hot stage lights, in an air-conditioned
studio, and so on) run the calibration procedure again.
To calibrate the oscillators and lters:
1. Hold down the preset button and press 0.
2. The front panel LEDs and display begin ashing as the Trigon-6
performs its auto-calibration procedure. Don’t turn off the power while
it’s doing this.
3. When nished, the front panel controls will return to normal and you
can play the Trigon-6 again.
