Synchronizes the delay repeats to external rhythms with the Tiptop Audio Clocked Delays, a collection of 8 stereo delay programs designed for the Z-DSP Eurorack module that let's you sync the delay time of the Z-DSP to an external clock input.
- With a quick set up, the clock input easily and exactly synchronizes the delay repeats to external rhythms generated by the Trigger Riot, Circadian Rhythms, or other clock sources. A Divide parameter is included with each program to switch between different divisions of the stereo ratios, creating a spatial audio clock divider, which automatically matches the repeats to a beat. Feeding the clock input odd clock divisions from a module like the Trigger Riot has the interesting effect of moving the repeats in relation to the beat.
- When it comes to their sound, some of the programs feature a pristine classic delay lines, while other programs insert a colored band-pass, low-pass, or high-pass filter into the feedback loop, imparting a beautiful harmonic transition to the repeats as they feedback through the filter and slowly decay away. Using the Z- DSP’s analog feedback path adds additional voltage-controlled stereo feedback, which can slightly drift the repeats out of their tight sync to the incoming clock due to the DSP chip latency, and also extend the delay tail intensity up into self-oscillation. Controlling the Z-DSP’s DSP chip speed externally via the Clock jack can even devolve everything into glitchy out-of-sync binary chaos.
- Mono programs use a single delay line up to 1000 ms long. Left and Right inputs are summed into mono and written into the delay line. Separate Left and Right output taps feed their respective signal outputs.
- Note that feedback, internal or external, also sums back into mono, so both of the taps are fed with each other’s signal. Using external feedback can allow for adjusting the amount of feedback each tap uses, and you can feed the outputs through different external processes like filters and distortion.
DUAL:
- Dual programs use two independent delay lines that are fed from Left or Right inputs. The length of these delay lines is limited to 500 ms. External feedback will only affect the same Left/Right channel. The ratios for dual programs are 0.5 and below because the tempo calculation is based on 1000 ms.
- Note: Program 6: Stereo Ping Pong has two delay lines like a Dual program, but the input is summed to mono.
- Single 1000ms delay line with inputs summed into mono and separate taps out to Left and Right. Feedback is done through the external Analog Feedback.
Mono Clocked Low Pass
- Mono 1000 ms delay line with summed inputs and separate taps out to Left and Right.
- A low-pass filter is in the feedback path and the cutoff lowers as feedback increases.
Mono Clocked Fdbk HPF
- Mono 1000 ms delay line with summed inputs and separate taps out to Left and Right.
- A high-pass filter is on the input and the cutoff rises with the feedback amount.
- Note that the repeats can be very long on this program.
Mono Clocked Bandpass
- Summed inputs into a Mono delay line. Two separate taps feed Left and Right outputs.
- Feedback runs through a one-pole bandpass filter with fixed frequency but increasing Q so the bandwidth narrows as the feedback increases.
Dual Clocked Delays
- Two 500 ms delay line with inputs for Left and Right and separate out to Left and Right.
- Feedback is done through the external Analog Feedback.
Clocked Ping Pong
- Summed mono input feeds the Left delay line, and the output of the Left is the input of the Right delay line. Each delay is 500 ms in length, and the internal feedback sends the output of the Right delay back into the Left.
- The low-pass filter cutoff is lowered as the feedback increases.
Dual Clocked HPF
- Two 500 ms delay line with inputs for Left and Right and separate out to Left and Right. A high-pass filter is in the feedback path and the cutoff frequency rises with feedback level.
Dual Clocked Feedback
- Two 500 ms delay line with inputs for Left and Right and separate out to Left and Right.
- Feedback is internal and a low-pass filter removes high end from the repeats as feedback increases.
