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.

StompBox Lite turns your iPad into a flexible Multi FX Processor which comes with 3 free effects; Delay, Reverb, Chorus and a further 16 Effects to choose from in the Online store.

StompBox Lite supports AudioBus and Apple’s Inter-App Audio making an excellent general purpose audio processing tool for all musicians, not just guitarists.

With StompBox you get the best of both worlds, a rack of professional sounding stereo effects (with far more control than simple foot pedals) and a foot controller to access a tuner and all your patches.

Simply listen through a pair of headphones, or attach to an external amplifier or hifi to truly experience the program in all its glory.

Once you have built up a library of patches, you can use the virtual foot controller to quickly and easily move between patches. The Virtual Foot controller gives instant access to all patch parameters and amp settings, with the ability to enable and disable individual effects at the touch of a button. If you want to modify an effect parameter, simply scroll the effect rack into view and make your changes.

In-App options include:

  • Media Player – Load your favorite MP3s and play along, you can even slow down the music without effecting pitch so you can play along at your own pace.
  • 4 Track Recorder – Record your own backing track.
  • Loop Station – Record your own loops.

Many guitar apps use a form of Amp Modelling which in most cases is just fancy form of EQ. This is great for electric guitars, but not so good for acoustic. StompBox allows various amp EQs both via the PreAmp and additional effects, but the important thing for acoustic guitar users is that these EQs can be completely bypassed. This is where StompBox really shines, giving a faithful reproduction of acoustic instruments. This also means StompBox can be used on keyboards too.
