MIDI Layers is an AUv3 MIDI plugin designed to allow sophisticated routing of MIDI data in hosts such as AUM or Cubasis. Have you ever wanted to play multiple instruments from a single master keyboard during a live performance? Would you like to be able to set up keyboard splits, crossfade layers or create an ensemble of layered instruments? If you answered yes to either of those questions, then MIDI Layers may be your solution. Layers allows you to create up to 12 scenes, each with up to 127 layers, spanning your entire master keyboard. These scenes allow you to seamlessly switch between various layer mappings at any time during a performance. Each layer controls the MIDI output, which can be routed to one of MIDI Layers 16 output ports and 16 channels. So if you have 5 layers in your scene, each layer is able to divert MIDI key input to 5 destinations, allowing you to control 5 instruments from one master keyboard. Layers can overlap, meaning you can create an ensemble of two or more instruments. Layers can also have cross fades so that you can fade from one instrument to another across a specified range. You can also control the velocity curves of a layer if you need to emphasize note velocity at a certain set of octaves. Each layer can also be remapped so that you can target a different key range on the destination instrument. This allows you to have several single note layers that can target specific drum machine samples for instance. You can assign a song per scene, or have several scenes containing parts of the same song. Switching scenes is simple, using the on screen scene buttons, via AU parameters, or you can even add a special control layer to a scene which can then be triggered via your master keyboard. It is also possible to assign a Program Changes to a layer. When you switch scenes, each layer can fire off its own program change to your destination instruments. Each scene can be assigned its own scale, which enables you to play using only the white notes so say goodbye to wrong notes. Finally, layers can be assigned to mute groups, allowing you to quickly turn on/off groups of layers with a single key or button press. Features: ○ Up to 127 layers per scene. ○ 12 scenes per preset. ○ Supports 16 output ports and 16 channels. ○ Remote switching of scenes using MIDI or AU. ○ Supports layer mutes and mute groups. ○ Named scenes with large scene selection mode. ○ Supports scales per scene which can be played using white notes only. ○ Each layer can define a Program Change that is sent when scenes are switched. ○ Supports per layer velocity curve. ○ Supports per layer remapping of notes on output. ○ Each layer can have a cross fade settings assigned. ○ Definable Master Keyboard size (6, 7, 8 or 10 octave). ○ Scene and mute control layers. ○ Provides default custom layouts. Please Note: This product will not work with GarageBand since it cannot load AUv3 MIDI plugins.
Wobulator
This audio effect plugin provides a stereo chorus with a unique "wobble" feature for a less predictable modulation. It can be used standalone or within compatible music production applications.
- Stereo chorus/modulation effect
- Adjustable delay time (10-100ms)
- Variable modulation rate (0.01-2.00Hz)
- "Wobble" parameter for unpredictable modulation
- Adjustable dry/wet mix
- AUv3 compatible plugin

Wobulator Modulator Plugin (AUv3) Wobulator is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic or GarageBand. Overview Wobulator is a stereo chorus / modulation effect with a wobbly twist! The chorus effect is typically achieved by modulating the time of a delayed version of the dry signal, and mixing the two. Typically, these delay times are very short, around 20ms. Wobulator includes a "Wobble" parameter that adds variation to both the rate and depth, which makes the modulation cycle less obvious to the listener. Parameters Active - Toggles the effect On or Off. Delay - Varies the base delay time between 10-100ms. Higher delay times can be used to create ADT (automatic double tracking) type effects. Rate - Sets the base modulation LFO frequency between 0.01 and 2.00Hz. Depth - Sets the amount of base delay modulation. For example, a 50ms Delay, with 50% Depth, will be modulated between 25 and 50ms. Wobble - Sets the amount of variation introduced by an internal wobulation matrix! At extreme settings the unpredictable nature of the resulting modulation can sound almost tape-like. When Wobble is set to zero, Wobulator behaves like a standard chorus effect. Mix - Sets the balance between the dry / input signal and the wet / processed sound. At 50%, the mix is an equal amount of dry and wet. At 100%, you hear the wet / processed sound only, which is good for wobbly tape effects! If the name sounds familiar, Wobulator is an updated version of the WOBULATER module developed for Voltage Modular by Waverley Instruments.
