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.

SploshBox Reverb / Sustainer (AUv3) SploshBox is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic or GarageBand. Overview SploshBox is vintage-flavoured digital reverb that also allows you to "freeze" the reverb tail for infinite sustain effects. The early generation of hardware digital reverbs had a slightly grainy and "unnatural" quality to them due to limited CPU and RAM. SploshBox has similar tonal characteristics, but while being kind to your CPU, it also features up to one minute of reverb decay time! Or, infinity when you engage freeze mode... Parameters Active - Toggles the effect On or Off. When SploshBox is turned Off, any reverb will continue to decay, similar to "trails mode" found in many effects pedals. Delay - Sets a pre-delay time before the incoming audio is passed on to the reverb DSP. This can be used creatively so that the initial attack / transients of a sound are preserved and not "smeared" by the reverb tail for example. Decay - Sets the overall decay time for the reverb tail. This is calculated as the time for a 0dB impulse to decay to -60dB. Typically, unless the incoming signal is 0dB, the actual decay time may appear a little shorter before it hits -60dB. Spread - Sets the stereo width of the generated reverb from totally mono, to very stereo-tastic! LPF - Sets the cutoff frequency of a lowpass filter on the generated reverb. Reduce this parameter to make the reverb effect warmer / softer. Mix - Adjusts the balance between the dry incoming audio, and the wet generated reverb, from completely dry to 100% wet. Freeze - Engages the reverb freeze effect so that whatever is in the reverb buffers will sustain continuously. By toggling Freeze in and out, very interesting creative and drone effects can be achieved, especially when assigning the parameter to a MIDI controller. Please note that when Freeze is On, reverb will not be applied to your dry input signal - it's as if the reverb is frozen in that moment. SploshBox does not store "frozen" audio between sessions, so if Freeze mode is On when restoring a session, you won't hear any reverb. If the name sounds familiar, SploshBox is a version of the SPLOSHBOX module developed for Voltage Modular by Waverley Instruments.
