Description by Satoshi Kajii(from the App Store)
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.
Each subscription will automatically renew 3 days before the expiration date for
