The Twin Delays Program
The Twin Delays program located in Bank 6 is a four
voice delay line with independently-adjustable level,
feedback, and delay time for each voice. Feedback can
be positive or negative. Feedback for Delays 3 and 4 is
cross-panned.
Independent low pass filters, adjustable between
120Hz and full bandwidth, are provided for the first and
second delay voices (Delay 1 Left Channel and Delay
2 Right Channel)and their respective feedback paths.
These voices also have independent panning controls.
