v2 Update – A little wider stereo spread, and found a couple rogue connections that weren’t going to the right places.

Although this patch is called Dueling Loops, it actually uses 2 sets of cascading delay lines, giving you up to 32 seconds for each loop. Loop 1 leans more to the left side, and Loop 2 leans more to the right. It is loosely inspired by the Soma Cosmos in principle, as well as the EHX 22500, and really any asynchronous looper.

From the UI page, press the red button to record to either Loop 1 or 2. By default the loop has infinite feedback, meaning it won’t ever clear, but the Aqua and Magenta buttons below the record button can select 50% feedback (the loop will slowly trail off), or 0% feedback (the loop will be cleared in 1 pass).

Next to the record button is the 2x audible button. Because the cascading delay lines can be up to 32 seconds long, engaging this switch will make both delay lines audible (so you will hear a repeat at ~16 seconds, and another at ~16 seconds). The beauty of the patch is that the loops are well out of sync, so the delay line lengths have been set at odd intervals for maximum “never happen again-ness”.

Down the middle row, we have the mix of dry to wet signal (Surf), on/off for a slow asynchronous tremolo (yellow), on/off for a High Pass Filter (White), and on/off for a reverb (Blue). Each effect has its own page with more controls. Only the essentials are included on the UI page. I have tried to label everything pretty meticulously, so it should be pretty easy to navigate.

CPU usage runs around 80%, so there is some flexibility in customization.

The patch is Stereo-In, Stereo-Out and has no footswitch control, but this could be easily Implemented
