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 note's pitch and velocity using knobs. Or don't, and rely on a global track's 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 you're 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 oscillator's 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 - it's quantized to octaves and fifths. A mix of these sound sources goes into the low-pass filter. The filter's 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 - Recording's start and end time can be quantized to the sequencer transport's start and stop - Synth can be used as separate AudioUnit - 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 can’t 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! "

Percussive Synth version 1.4.2
Updated At: 2026-06-03
Changes: Version History This bugfix release includes:
* Returned the "lost" Perc Synth Sequencer AudioUnit.
* Ensured the app's default MIDI in/out works as expected.
Some helpful information:
Using AUM as an example, this is how you can find Perc Synth AU plugins:
Perc Synth Plugin - audio channel -> inserts/effects (middle "+" button) -> Audio Unit Extension.
Perc Synth Sequencer Plugin - MIDI channel -> Audio Unit MIDI Processor.
If you exchange MIDI within one device, say, in AUM, it's very straightforward, just create a route between your plugins and the Perc Synth standalone.
But when you want to send MIDI over to your Mac or another remote device, select "Network Session" as MIDI Input/Output in the app's "midi io" section. On Mac, open MIDI Studio, enable a Network Session and route network MIDI traffic to the IAC Driver device. Using the IAC Driver is helpful because some apps won't provide the "Network session" option.
