2.3. Auto-tune PolyBrute
One thing to remember about analog synths is that many components are temperature-
sensitive, which can lead to small variations in pitch and timbre over time. It's part of what
makes them seem "alive." We recommend that you let the circuits stabilize for 5-10 minutes
after power-up. If the tuning still seems a bit loose after that, you can run one of the
calibration routines as described below.
There are three types of auto-tuning, and you can run one by itself or run them all. Here's
how:
1. Press [Settings]
2. Select Misc (Assign button 8)
3. Select Voice Auto-Tuning (Assign button 4)
4. Now select button 1, 2, 3 or 4 depending on the desired tuning target.
Here's what the options mean:
•
VCO Calibration
tunes both oscillators for each voice. You may want to run this
one more often than the others.
•
VCF Calibration
tunes both filters for each voice. It also makes sure the filters
track the keyboard well.
•
All
runs the calibration routines automatically, one after the other. This will also
calibrate the VCAs.
It takes a while to run the calibration routines, which is why we made it possible to launch
them individually as needed.
2.4. What is digitally-controlled analog?
Unlike early synthesizers, PolyBrute has the advantage of digital control over its analog
circuitry. It's the best of both worlds: the warmth and hands-on control of real analog, with
the ability to save and recall patches and settings (not to mention USB, MIDI, and other
modern features).
For this reason, when you load a patch the physical positions of the knobs and sliders may
not match the parameter values stored with the patch. But the PolyBrute has three modes
that allow you to specify how these controls respond when they are first moved. These
settings are available in the Editor and at Settings / Misc / Knob Catch.
•
Hook
- a control must sweep past the stored value before it changes the
parameter. Benefit: smooth changes.
•
Jump
- the value jumps to the position of the control as soon as you move it.
Benefit: instant response.
•
Scaled
- the parameter changes from its stored value when the control moves,
and the range is scaled (averaged) to cover the remaining values in that
direction. When the control direction is reversed the normal parameter range
is restored. Benefit: instant response and smooth changes. This is the default
setting.
It's always possible to audition the settings of the front panel. This process is described in
the Panel mode section [p.46] .
