waylomodelay88 free multi-fx | chorus | delay | phaser by sean wayland waylo software

waylomodelay88 is a free multi fx and chorus and delay and phaser VST, Audio Unit plugin developed by sean wayland waylo software. Compatible OS(s): Windows 64b, macOS.

This is an audio plugin which is works in a fairly similar fashion to recent Japanese made “Ultimate Delay”-STOMP guitar pedal.

There are 8 bands of delay. The delay times can be modulated by a Sine wav. What that means is that time of the delay is slowly changing from say 98 to 102 and back smoothly with a delay time of 100 and a mod depth of 2. Really short delay times with modulation creates a chorus effect. The last 4 delays also have feedback added and the feedback can be adjusted. Once the feedback gets high enough the delay will repeat forever. Lower than that amount the delays slowly die out. I usually use 4 short delays and 4 long ones. The long ones had feedback. In this plugin the delays are just panned left and right alternatively.

The plugin was made with JUCE and MAX7.

It’s a 64-bit plugin and won’t work on an older 32-bit computer.

I have compiled OS X .vst and .component (apple) plugins and a windows .dll.

My friends and I have tested it out with Cubase, Reaper, Logic and Mainstage.

It works with recent windows and OS X operating systems (as of dec 2017).



Here is a demo of it. This is a pedal steel sample from the Yamaha QY70 run through it.






Hopefully the controls are pretty self explanatory. There are sliders for each delay (time, modulation frequency and delay level), one for direct level and one for mod depth. There is also 4 more sliders which control the feedback for the last 4 delays.


My suggestion of how to learn to use it is to start with the first 2 delays and set the times really short and the frequency and amount really short.


The level of the sliders on my plugin don’t really relate exactly to this list but this should give you an idea of how you might want to set it up.




One quirk of the software is that if you load a saved preset button you have to press the yellow ” load current preset ” button on my plugin to get the sliders to move to the preset values.



Have fun with it.
