WoodTroller is NOT an app to annoy people. It’s an MPE and midi V2 multi touch bar keyboard and midi controller : The MPE touch bar supports multiple notes with individual pitch shift (horizontal movement), pressure and cc74 (vertical movement). WoodTroller has 8 general purpose rotary controls : - Each can send 6 different CC messages to different channels. - Each of the 6 command values can be mapped differently to the full rotary range. - So 1 rotary can control several parameters on the same or on different instruments. - Rotary names, colour, unit, range can all be user set. WoodTroller also has 8 general purpose on-off or push buttons : - Each button can send up to 8 different midi commands (CC, PC, NoteOn, …) to different channels. - This allows to quickly switch multiple midi instruments or devices to another program or to other settings. - Each midi command’s data value can be auto incremented/decremented. - All button names, colour, type can be user set. All settings can be stored in presets in iCloud which yield automatic preset syncing between several WoodTrollers on different devices. WoodTroller is available as stand-alone app and as AUv3 plugin.

Concept: “Jacquardi4” is an AUv3 instrument that does not make any sounds but can send out 4 analog-like “Envelope” signals via MIDI control changes (MIDI CC). That is, the app contains 4 MIDI modules of envelope generator. The user can use them for modulating any parameter of 3rd-party’s plugins that can be assigned to MIDI CC , for example, cutoff frequency. System Requirements: AUv3 host that has a flexible capability of MIDI routing (AUM, apeMatrix, LoopyPro, etc). Usage: Just assign MIDI keyboard to Jacquardi4's MIDI IN (it needs to trigger Jacquardi4) and assign Jacquardi4's MIDI OUT to 3rd party's plugins. Explanation of sliders: Channel: determines MIDI channel. Control Rate: determines the resolution of MIDI processing. Higher value, higher resolution. Active: turn on or off the module. Useful when using MIDI learn functionality of 3rd party plugin. MIDI CC: determines MIDI control number. (text-editable) Amp: determines amplitude in dB Offset: determines an initial value. Attack: attack value. Decay Time: decay time value. Decay Curve: decay curve value. Sustain: sustain value. Release: release value. Explanation of Preset File System: At first make a new bank folder, in which you can save a preset file. And push "Save As" button. Also the user can export or import preset files.
