Radical Delay DX features six delay modes, all of which are adjustable to play from 24kHz down to 1.6kHz bandwidth using the CLOCK knob.
The maximum delay time varies by mode and clock rate, but it varies from 680ms to over 5000ms. Yep, that’s over 5 seconds of delay time, but it sounds terrible. It’s gross. Don’t say we didn’t warn you.
MOD Digital delay with modulation. Tweak controls the mod depth and ALT controls the mod rate.
BEND Pitch shifted delay. Tweak selects the interval (-12, -7, -2, -1, detune, +1, +2, +3, +4, +5, +7, +12) and ALT puts the shift before or after the delay.
DUAL Dual-tap delay line. Tweak controls the delay time for the second tap and ALT controls its feedback.
REV YALED ESREVER. Tweak warps the delay from forward to reverse, with “tape stop” sounds available in between. ALT mixes between the main reverse delay and a forward delay. Just want reverse? Set Mix, ALT, and Tweak to maximum.
ARP Chiptune arpeggiator delay. Tweak controls the speed of the arpeggiation and ALT selects from 8 scale options.
DYNA Dynamic delay. The delay time sweeps with your picking attack. Tweak controls the sweep amount and direction, and ALT sets the volume sensitivity. Be careful with short delay times - that’s where the laser birds live.
