ONO-SENDAI is an hybrid between a generative drum machine and a groove box with unique takes. You play it realtime by ear, rewriting and morphing the sequencer quite elastically. We have taken Mutable Instruments code from Braids as a base to build the oscillators and then applied percussive estrategies. You can apply LFO´s and envelopes to sculpt the sound in realtime while you record parameter locks. It rewrites the sequences in realtime giving variation and organicity to the sound.

    The result is a mix of retro sounds and quite futuristic and avant garde landscapes.

The firmware is in expansion rigt and there are planned a good chunk of new features like MIDI implementations and some alienesque ideas.

    FIRMWARE 1.6 AVAILABLE, HAS THE FOLLOWING FEATURES:

-Redesigned graphical interface.

-Clearer sound (no glitches)

-The coarse pot plays in chromatic scale (always in tune, you can still detune with the fine pot)

-Easier/more logical interface (recorded parameter locks are implemented when you release theREC button, no need to turn another potentiometer/key)

-CLOCK IN

-CLOCK OUT

-CLEARER SOUND

-PRESET LOAD

-BPMs displayed on screen

-USER MANUAL AVAILABLE

Please read the QUICK USER GUIDE to learn how to play it. It´s located here:

      https://github.com/spherical-sound-society/ONO-SENDAI/blob/main/ONO%20SENDAI%201.6%20QUICK%20GUIDE.pdf

And the FIRMWARE is here:

      https://github.com/spherical-sound-society/ONO-SENDAI/tree/main/ONO_1.6

To change the firmware in your ONO-SENDAI just connect it to the computer with a USB C cable. Then, press BOOT, without releasing it press RESET. Release RESET, release BOOT. A window will open in your computer. Just drag the firmware that you want to install to that window and you are ready to play it.

 We have a video explaining how to update your synths here:

ONO-SENDAI feeds from a common USB C type cable (not included) and therefore can be powered via a Power ank turning it into a portable unit.

     It comes comes in 3 flavors:

-As a fully assembled unit.

-As a complete kit (with all the components) so that the user can play with it from the beginning.

-As a prepolulated PCB + Programmed microcontroller for medium and advanced DIYers.
 The user has to source the rest of the components and build the synth.

There´s a user guide that explains every function, knob and button that you can download here:

And there´s also a interactive BOM for the DIY users.
