EQ

There's a two-band parametric EQ for the wet signal with low-cut and high-cut with adjustable slopes for the cut filters. The EQ stuff is on a separate GUI page with a graphical display. Source

Oscillating

The Master feedback goes to 200% for oscillating delay effects. Source

Effect on delay trails only

To add an effect to the delay trails only, not the direct tone, place the delay in a parallel row and add the effect after it.

Auto Delay

When this Tempo parameter is set to “ON,” any delay blocks that are bypassed will become active whenever a tempo is tapped in. This allows you to set the tempo and un-bypass your delay block(s) from a single footswitch. See Tempo, use of.

Muting the delay with trails fading out

By attaching an external controller (connected to a pedal or switch) to Input Gain, you're controlling the delay level at the input stage. This will make delay trails fade out nicely when muting the delay.

Spillover

See Spillover of reverb/delay trails

Maintaining unity gain

When using Mix to control the volume level of the delay, the volume level of the dry signal is affected also. In other words, when turning up the delay level, the dry signal's level decreases. To deal with this: turn up Mix to 50% and set Level to +6dB. Or put the Delay in a parallel row, see Effect blocks: parallel rows.

CPU utilization

The Tape and Ambient delay types require more CPU cycles than the other types.

Mono Tape Echo

• Firmware 4.00 added a "true" Tape Echo mode to the Delay and Multi Delay blocks. It's mono only (the Stereo Tape is the same one as in previous firmware). From the Release Notes: "Added Tape Echo algorithm to Delay and Multidelay blocks. This algorithm simulates a tape echo where modulation occurs due to tape speed variation. In the Delay block the algorithm is implemented as a two head monophonic tape “deck”. The Time/Tempo parameters set the distance between the record and first playback head. The Ratio parameter sets the relative distance between the record and second playback head as a percentage of the first playback head. The Multidelay block is implemented as a monophonic deck with four independent heads. See the updated manual for full details."
• Cliff: "The algorithm is a single tape with one record head and two playback heads. The signal from each head can be fed back (Feedback) and panned and leveled. Head 1 Time sets the delay time of head #1 when the Motor Speed is 1.0. This is analogous to the distance between the record head and the playback head in a tape deck. As you increase the time you move the heads apart and vice-versa. Whatever the time is set to is the delay time when the Motor Speed is 1.0. As you increase the Motor Speed the tape moves faster so the delay time decreases and vice-versa. The relative position of the heads do not change. Ratio sets the delay time of head #2 as a percentage of head #1. If you set Ratio to 50% then the delay time of head #2 will be half that of head #1. This is analogous to positioning head #2 exactly half the distance as head #1 from the record head. In brief: Delay Time = distance between heads, Motor Speed = tape speed. The LFOs modulate the motor speed. Modulating the motor speed (which changes the tape speed) is a very different effect than modulating the delay time. You can hear the difference between by varying the Motor Speed manually and the Head 1 Time manually. In a typical tape deck the tape speed is not constant. In the days of tape recorders much effort was expended on trying to keep the tape speed as constant as possible. This included periodic maintenance. However, when applied as a delay effect, the variation in tape speed could create a desirable modulation. Tape Echos, in particular, were built to cost points and suffered from considerable tape speed fluctuation. The two primary components of speed variation were termed "wow" and "flutter". Wow arises due to low-frequency variations in the tape speed. This is typically due to variation in the speed of the motor itself and/or eccentricity of the pulleys. Flutter is a high-frequency modulation and arises due to eccentricity of the capstan and pinch roller." Source
• Cliff: ""The LFOs actually modulate the tape speed. It’s the same as attaching a modifier to the tape speed. This is because in an actual tape deck the tape speed is what is typically subject to variation. Wow occurs due to variation in motor speed (or belt/pulley, etc.) and flutter is due to capstan and pinch roller. Wow varies the tape speed slowly, flutter is a high-frequency variation in speed. The actual delay time is very stable since the heads are stationary and the tape is taught between the heads. Delay modulation due to tape stretching is negligible."
