iPhone app Percussive Synth

Percussive synth will accompany you while you jam, be your groove experimentation space, or be your source of recording material you may export and mix in a DAW.

Fine control over many virtual analog synth parameters allows for vast sonic experimentation potential.

And unique sequencer implementation equipped with such potential creates an exceptional user experience.

The app consists of the sequencer and the synths engine:

SEQUENCER

A rhythm or a melody can be created using the sequencer.
Tap notes into one of the four tracks, one track for each voice of the synthesizer.
Set notes pitch and velocity using knobs.
Or dont, and rely on a global tracks pitch setting.

Each synthesizer voice has a completely independent set of parameter values, so you get four different synths playing polyphony.

One of the cool features of the sequencer is the ability to switch between straight and odd subdivisions - a note can be one-fourth of the bar, but also one-sixth, and one-tenth.
Also, notes can overlap and re-trigger after overlap ends, which allows for creating weird rhythms when used with odd subdivisions.
And if youre into drone music - BPM can go over 9000.

SYNTHS

The basis of each voice is two oscillators and a white noise generator.
Each oscillator can produce a square, saw, triangle, or sine wave shape.

`The second oscillators frequency can be discretely shifted from -2 to +2 octaves, or smoothly offset using the osc2 freq knob.` + `Oscillators frequency can glide to a higher or a lower value - decay time will set the duration of this glide, and decay amt the frequency destination - its quantized to octaves and fifths.` +

A mix of these sound sources goes into the low-pass filter.

The filters cut-off frequency can be dynamically controlled by ADSR (attack, decay, sustain, release) module.

The amount and direction of this control are set by the env knob.

The second ADSR module controls the volume envelope.

OTHER FEATURES

- Sequencer and synths modules have separate preset managers and undo histories

- Audio can be recorded and exported as .wav files from the app

- Recordings start and end time can be quantized to the sequencer transports start and stop

- 8-voice synth and sequencer can be used as separate AudioUnits

- Ableton Link support

- MIDI io, CC mapping

- Export preset files

- Toggle between quadratic and linear ADSR

- Toggle velocity sensitivity in knobs

Some of the amazing feedback from our precious users:

I cant stop playing with the app and love using Record in stand-alone for doing quick exports with live tweaks

Really Good work man, different from my habitual drums seq plays, and this is good

Definitely some lovely sound coming out of this

The sequencer looks very unique and interesting for odd and glitchy tunes

I have only scratched the surface of it.
Going to be awesome for sure.
Wow high praise indeed.
Can hardly wait to play some more.
Enjoy!

The sequencer in the standalone is really interesting and fun to play

Still diving in.
Lots of fun.
The flexible simplicity of the sequencer with wide range of bpm is really cool.
So far the sounds make me believe i am existing in an apocalyptic 80s film

Recently purchased your app and i love it so so much.
I do all my jams in AUM and have been looking for an interesting sequencer, found yours and i love it! ,
