Xynthesizr is a streamlined yet capable 32-step matrix sequencer/monotimbral synthesizer with generative features and MIDI.
"This really is a lot of fun and, hooked up to a synth like Thor or Z3TA+, there are plenty of creative options to be explored here." - John Walden, musicappblog.com
"Xynthesizr is about the only tone matrix app that can keep up with my short attention span. There are so many ways to shape, and constantly reshape, your sound... There's a lot to play with here!" - Tim Webb, discchord.com
"Overall, Xynthesizr is a very interesting instrument that is fun to play and lovely to look at." - Tom Flint, Sound on Sound
"Xynthesizr holds a lot of creative potential, and between a user friendly interface, a practical onboard synth, inspiring generative features, and solid MIDI implementation, this is a useful tool that can really benefit a wide range of iOS musicians." - Chip Boaz, iosmusicandyou.com
"...one of my absolute go-to apps" - Sean Garland, iosmars.com
Create patterns and modify them in real time, or let Xynthesizr do it for you using its morphing algorithms. Change scale and key, or transpose within a scale on-the-fly. Tweak parameters of the internal synthesizer or output MIDI to your favorite apps and devices. Record and share your creations.

Synthesizer and FX feature:
◦ 32-bit floating point sound engine
◦ 16 voice polyphony
◦ 2 antialiased oscillators per voice
◦ 4 waveforms (sine, triangle, sawtooth, square)
◦ 4-pole (24 dB/oct) low-pass resonant filter
◦ 2 ADSR envelope generators (amplitude and filter cutoff frequency)
◦ 2 LFOs to modulate 4 selectable LFO targets (filter frequency, pitch, amplitude, second oscillator detune)
◦ Stereo delay, reverb and randomized panner
◦ Ableton Link support
◦ Audiobus 3 support (including AB MIDI)
◦ Added an on/off switch for Inter-App Audio tempo synchronization
◦ Added an option to have notes labeled as MIDI note numbers (e.g. 60 instead of C4; see app settings)
◦ Extra note labels on step 17 (iPhone)
◦ Now adding asterisk to song and preset names instead of displaying as ‘(Unsaved’) when changes happen
◦ Settings and MIDI Settings dialogs can now be closed by tapping outside their ‘windows’
◦ New About screen
◦ Updated user guide
◦ Updated AudioShare SDK
◦ Fixed timing irregularity on playback start when using internal clock
◦ Fixed a crash when an input MIDI note is out of range in scalar transposition mode
◦ Fixed MIDI CC control over OSC and LFO waveform, OSC octave, LFO destination, step length controls (it would jump to the first value regardless of CC value)
◦ Fixed a bug where the sound engine wouldn’t turn on (i.e. make sound, despite the switch being in the ‘on’ position), if the app was launched with it off
◦ Fixed some app lifecycle management issues when in IAA or AB session (this should fix the lost sound issue some experienced)
◦ Fixed an issue where the squares in the first grid column could not be selected with 3D Touch enabled
◦ Fixed a bug in song/preset select mode where checkmarks would be displayed incorrectly when scrolling the table
◦ Fixed pattern shift down button malfunctioning on some devices
◦ Various other fixes and improvements
Ratings and Reviews
Could be good for loops if you could get the steps past 19. Not even with a stylus. Hard to even get it back to 16. Change it to a slider. Not sure why there should be odd numbers anyway. Fun to play with you don’t try to adjust anything. Lowered to 2 stars because the manual I finally found is no help. Edit: found that if you go into settings and change Knobs to linear you can get all 32 steps. Raised stars to 4, but now the tempo is 119.8 and I can’t get it to 120.
Excellent Midi Sequencer...
...With a a brilliant synth engine. This is now permanent on my AUM set up to trigger other synth. I love the multiple channels and the randomizer feature.
*Update brought Ableton link 🙌🏿 . Best thing ever.
- 128 steps
- pattern bank (to trigger for live performances)
- When playing and switching to another app (AUM, iSEM) and I switch back to change a parameter during live performance, the sequence stops (obviously a vibe killer). Am I doing something wrong?
- In the Midi options there are 22 colors and channels, how can I actually access them to create patters? Am I missing something?
Anyway, keep up the great work.
- Ableton Link support is now in beta, should be available soon if everything goes well.
- Could you please contact me at firstname.lastname@example.org or via the app's built-in feedback form about the sequence stop issue? I would like to know a way to reproduce it.
- The 22 colors is a quirky bit: it's the maximum theoretical number of scale 'periods' or 'repeat intervals', given the possibility to create scales consisting of only one note, and having a repeat interval of less than an octave.
Always a good addition to your synth library. If you need a step sequenced, try experimenting with this and make a beat. Hopefully it can add more steps to be a song sequencer.
With Family Sharing set up, up to six family members can use this app.
