![]() I used the standard dual op-amp triangle/square LFO with red and green LEDs on the square wave output. It sounds similar to what Mike did with his phaser. I did that with the LFO on the first synth I built (over 20 years ago!). Quote -In some respects, the ideal compromise of space, complexity, and functionality might be a 2-LED or bi-color LED display that swelled in brightness and switched colors at the crossover point (halfway during the descent, and halfway during the ascent). KNowing what your LFOs are doing right this instant is always useful for planning out sweeps. Beside them is a 20 segment vertical meter type LED-indicator that shows their sum.Īs we've seen on oh so many fronts, happy implementation is often a function of dependable intelligence. Each has an associated VU-type meter on the front panel so you can see where each is in the sweep cycle right now. There are two modulation sources onboard, each of which can be "reset" to the beginning of their sweep cycle. A rackmount phaser, flanger or other modulation effect. Of course fitting it in the allotted space might prove tricky. A bit like an LED display with infinite resolution (instead of 10 or even 20 segments). The general idea is to be able to anticipate the turnaround point for setting speed, either by means of tap tempo or by manual control.Īn analog VU-meter would be nice as LFO display :) In some respects, the ideal compromise of space, complexity, and functionality might be a 2-LED or bi-color LED display that swelled in brightness and switched colors at the crossover point (halfway during the descent, and halfway during the ascent). ![]() It's been a couple of years since I've seen that one, so I don't remember whether it simply flashed or whether it swelled as the Liqui-Flange display does. Here there are two different-coloured LEDs, one for one half cycle of the sweep, one for the other. One of the slightly more useful LFO displays I've seen is one that Mike Irwin implemented on one of his more complex phasers. While perhaps not as useful for keeping track of a 12-second sweep as something like a rolling 10-LED meter-display might be, it is pretty much as useful as a single LED can be, and really helps a lot for planning out taps. Instead of simply blinking briefly at the "turnaround point", it gradually glows brighter over the sweep cycle. I'm not sure whether this feature was built in already at that time and I overlooked it, or whether our collective whining here made a difference, but I am very pleased to report that the status LED on the Liqui-Flange now does what I wanted it to do. ![]() I had played with the prototype over the summer, but hadn't touched one since late July and hadn't seen/tried the production version yet. Huge" Tripps over at Line 6, one of which is the production version of the Liqui-Flange. On Monday, I was pleasantly surprised to receive a bunch of modules from the very kind Jeorge "Mr. ![]() Especially in the absence of any visual feedback to aid the imagination. Once the sweep cycle gets long enough, though, it gets harder to imagine where the cycle is at right now, and harder to strategically tap your foot on any tap tempo switch. The basic underlying principle was that when the LFO speed is fast enough to follow or anticipate in your head, you can mentally imagine where the cycle is at right now and tap your foot appropriately to set the intended speed. If you followed that thread (dear lord, I need to learn how to use the search feature! :icon_rolleyes: ), you will know that some suggestions cropped up including a brightness "swell" over the LFO cycle as well as assorted multi-LED "visual metronomes". I had expressed some frustration earlier in the fall with the visual monitoring of tap tempo for slow vs fast LFO sweeps.
