PolyDelay vs XenoVerb

PolyDelay Polyrhythmic Delay Plugin (AUv3) PolyDelay is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand. Overview PolyDelay is a dual delay line / stereo effect with optional host tempo sync. While PolyDelay can be used to create interesting stereo polyrhythmic delays, it can also produce more familiar delay patterns such as dotted eighth and quarter note triplets. Polyrhythms, Divisions and Beats PolyDelay calculates delay times based on a BPM (beats per minute) tempo, and the polyrhythmic notation of D:B, where D = divisions and B = beats. For example, 3:2 would mean that the time for 2 beats should be divided by 3. If you're more use to the idea of note lengths and delay times, such as quarter notes and dotted eighths, etc., this might be confusing at first, but hopefully this guide will help. Firstly, everything starts with the beat! So, for 120BPM, each beat (or quarter note) will be half a second, or 500ms. So if you want a quarter note delay, you want 1 division within one beat, so you would set Divs and Beats to 1. Here are some typical note values, lengths (120BPM) and their D:B values: 1/4 = 500ms = 1:1 (take the length of one beat, and divide that by one) 1/8 = 250ms = 2:1 (take the length of one beat, and divide that by two) 1/16 = 125ms = 4:1 (etc.) 1/32 = 63ms = 8:1 (etc.) See how the divisions are doubled-up for each note? And here are some dotted and triplet note examples - see how the D:B numbers start to get interesting! 1/4D = 750ms = 2:3 1/4T = 333ms = 3:2 1/8D = 375ms = 4:3 1/8T = 167ms = 3:1 A classic stereo delay would be 1:1 (1/4) left, and 4:3 (1/8D) right with Width set to max. If you want a really long delay, a 1:8 setting would give you 4 seconds at 120BPM with Multiply set to Normal, or 8 seconds set to Half. The Presets also include some typical (and not so typical!) examples to get you started. The fun really starts when you start mixing "unusual" (typically odd numbers) divisions and beats, such as 5:4 or 2:7. These sorts of relationships are what we typically refer to as polyrhythms. Try experimenting with PolyDelay on simple sequences and drum parts / patterns and you may start to hear all sorts of interesting rhythmic interplay as your brain tries to figure out what's going on! For additional tone-shaping, PolyDelay includes variable stereo width, a high and low pass filter, stereo modulation and internal limiting to keep audio levels in check.

XenoVerb is a versatile reverb processor featuring both classic and creative reverb algorithms delivering a wide range of reverbs with a clean and simple interface. MULTIPLE ALGORITHMS - ROOM: A flexible room algorithm useful to create classic environments ranging from small studios to large dancing clubs. - ROOM B: A smoother revision of the ROOM algorithm. - HALL: A classic yet versatile hall reverb ranging from small concert venues to huge canyons. The smooth reflections and soft building tail are beautiful on pianos, drums and vocals. - LARGE HALL: A bright large hall inspired by late ‘80s Japanese studio reverbs. The smooth tail works like a charm on drums, vocals and synthesizers. - PLATE 1: A simplified version of a classic plate algorithm found in late ‘70s hardware processors. - PLATE 2: An extended version of a classic plate algorithm found in late ‘70s hardware processors. Very smooth, great on vocals, drums and pads. - PLATE XL: A huge and dense plate algorithm with a pitch shifting vibrato as modulator. Perfect for ambient synths, pads, guitars and vocals. - SPRINGY: A fully algorithmic spring tank reverberator. Dirty, ringing and metallic, great on guitars and to add sparkle to synth and percussions. - GLASS (FDN): A modern highly diffusive and transparent reverb. This versatile algorithm can be used on any source material and can range from small ambiences to outer world spaces. - FLOW: A lush, smooth, hugely diffusive creative reverb based on the ‘90s hardware processors, where a lot of allpass blocks were used to create dense late reverberation. The result is a lush, soft building reverb, great for pads, guitars, voices and creative sound design. - SHIMMER: A smooth reverb with a dual pitch shifter in a feedback loop creates an evolving harmonizing soundscape. That’s a classic effect pioneered by Eno, Lanois and U2’s The Edge. - BODE: A weird sound design oriented algorithm made by placing a frequency shifter in the reverb feedback loop. Useful to create metallic resonances and drones. - FORMANT: A creative reverb algorithm featuring a formant filter before the reverb tank.
