Xynthesizr: 32-step matrix sequencer/synthesizer with generative features and MIDI

By Yuri Turov

Open iTunes to buy and download apps.


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,

"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,

"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,

" of my absolute go-to apps" - Sean Garland,

Great sequencer

Easy to use, stable, fast to program; use it to control your other iPad synths and drum machines. Visually, you can be looking at up to four different MIDI outputs simultaneously on one screen interface, which can be very helpful: bass, drums, keys x 2 for example. Also good for real-time tweaking of sequences on the fly. 32-steps, you can choose length, so odd time signatures like 9/8 are no problem, which is a BIG plus. Internal synth is actually pretty good too, I started off just using it to doodle with, but actually wind up making some sounds that I want to use. Velocity programming is a breeze, would love to see that extended to other modulation, filters or volume. This also has very robust generative features.
Sometimes I want a keyboard or pad input for MIDI, but when I want step sequencing, Xynthisizr is king. As easy to use as Gadget or Auxy but with MIDI out!

One of my top ten. So many possibilities

Very smooth and obvious workflow interface. Can make mellow drones or crazy randomized acid madness... the randomization is great because you can choose random or conways game of life. There are even two sets of rules for game of life setting. This developer seems great. Looking forward to more. Really fun and productive app for me.

Another big fan

I love how easy this is to use, and especially appreciate that it is universal. It works just as well coming up with quick ideas on iPhone as well as iPad. And the fact that it is possible to assign different MIDI channels to different sound sources via Audiobus is icing on the cake.
