To provide quick access to a variety of delay configurations Roland’s RE-201 includes a 12 mode selector, and this is replicated on the T-RackS version. The first four modes activate only the delay heads (the spring reverb is bypassed) with modes 1 to 3 each activating a specific head and mode 4 a combination of heads 2 and 3. Modes 5 to 11 activate combinations of specific delay heads and spring reverb, and in mode 11 all three delay heads and the reverb are active. Mode 12 is just the reverb. If this all sounds a little bit confusing, LEDs next to the Delay Pans provide you with a visual indication of which of the heads are active. If you really need to check what’s happening there’s a detailed table in the manual. Replicating the delay time limitations of the original hardware means picking a mode that works best. So, Mode 5 is great for a reverby slap back delay, while Mode 4 is better for simple panned double delay.
