PRESET AND EXPRESSION PEDAL USE
The Mainframe can store one custom setting in memory. This custom
setting can function as a preset with a snapshot of the toggle switch and
each knob position, or as a custom expression pedal setting allowing you
to sweep any combination of knobs between two saved positions in any
direction. Press the EXP/PRESET button to activate the saved setting.
If no custom setting has been made, by factory default an expression
pedal plugged into the EXP jack will control the sample rate of the
Mainframe. At the heel position, the sample rate will be the full 48kHz. At
the toe position, the sample rate will match the sample rate set by SAMPLE
RATE knob or by Sample Rate Tuning Mode. There is no factory default
preset, so if no expression pedal is used, pressing the EXP/PRESET button
will not load any different sound.
When making a custom setting, the heel and toe positions are saved for
an expression setting, and the toe position is also saved as a preset that
can be recalled without an expression pedal. The toggle switch position is
also saved and can be recalled as a preset or with an expression pedal.
CREATING A CUSTOM PRESET
1. Press and hold the EXP/PRESET button until the green LED starts
blinking slowly.
2. Press and release the EXP/PRESET button again. The green LED starts
blinking rapidly.
3. Turn any of the knobs and the FILTER switch to the settings you would
like to use for the preset. If the controls are already in the position
you would like for the preset, there is no need to turn anything.
4. Press and release the EXP/PRESET button. The green LED will light
solid, indicating that the preset is active. If Sample Rate Tuning Mode
was active during the creation, it will be turned off and the tuned
sample rate will be saved to the preset.
