Hey, I'm Fred developer of FAC
We share the same passion: MUSIC. A wonderful universal language and an amazing source of happiness.
FAC is a one person business, and as you may guess designing such apps is a very long process.

You are my motivation, and as I’ve already tweeted, your support provides me an instant coding nitro boost. So the more you give the more you receive.
Being a MIDI effect in its essence, controlling your synthesizers parameters (e.g volume, cutoff, res) with MIDI CC and notes, FAC Envolver is also able to transform the input audio via two exclusive effects: a Noise Gate and a Trance Gate. This combination is the key to breathe life into your sound, providing interesting natural modulation and sequences that will always be different by nature.
Under the hood, FAC Envolver is an envelope follower delivering MIDI data generated from the contour of a signal. The source of this signal may come from two distinctive circuits: the first one is a classic envelope follower and the second one is a rythmical pattern called trigger gate. Both circuits are responsible for providing a signal envelope that can be altered by a set of parameters and delivered as MIDI control change messages (CC).
The generated signal envelope also passes through a gate detection mechanism driven by a threshold. When the signal goes above the threshold, the gate is open and when the signal goes below, the gate is closed. This open/close sequence provides a second envelope which is delivered as MIDI CC (on/off) and notes. The pitch of the note may be set within the effect or from an external value provided by MIDI input. Both may follow a particular scale progression.
The envelope follower circuit also provides a noise gate to control precisely the level of your audio signal. This uses the same open/close sequence built by the gate detection mechanism that delivers MIDI data but acts on the audio. Following the same logic, when the second circuit - the trigger gate - is engaged, the open/close sequence provides a trance gate style effect to the audio.
FAC Envolver is a stereo effect and provides two slots, one slot per channel. Both can be linked to facilitate the manipulation. The audio can also be turned to mono and the dry and wet audio can be mixed.
Following the diagram below, the sound flows from the left to the right or from the input to the output.
Slots 1 (L) and 2 (R)
Note: The MIDI/AUDIO combo makes FAC Envolver usable in every host, even the ones that still do not provide MIDI out support, in this case the MIDI generator is disabled and the fx can be used as a standard AUDIO fx.
As with all FAC products, the interface has a unique sober look and provides a great user experience. The value of each knob can be monitored at any time and two waveform viewers provide an accurate visual monitoring of the input signal levels layered with the output envelopes. The knobs are very responsive, natural and follow a specific curve according to the parameter type.
FAC Envolver also comes with factory presets to provide you a source of inspiration to satisfy your needs in any situation you might require.
The preset button provides common management features: loading, organization, and saving. The left and right arrows allow fast navigation shortcuts among all the presets (factory + user), a short press on the center label provides a detailed list of all the available presets, select the one you want to work with. On the other hand a long press (hold) provides contextual operation. For factory presets it's possible to save the current preset to a user preset, for user presets it's possible to rename, save and delete the current preset.
The provided factory presets are organised by the following categories:
FAC Envolver - ApeMatrix
FAC Envolver - Garage Band
FAC Envolver - AUM (AUDIO + MIDI Keyboard -> Envolver CC/NOTE -> Zeeon)
FAC Envolver - Cubase
Check out what musicians think about FAC Envolver
Brilliant app this, able to create the most subtle and natural modulations from different sources, more than just using an LFO and of course you can combine it with or control an LFO so the sky's the limit
I think a lot of people are going to absolutely love this. Once you get your head around the routing the power of this is almost limitless.
Just when I was thinking most Dev's/Apps are a pretty boring and uninspiring bunch, along comes a killer app that can do so much, and is so open to interacting with IOS and hardware. 10 outa 10!!
Brilliant! Game changer right here.
