I use python and mido. In the hacktribe-editor repo there is e2sysex.py with functions for getting and setting patterns. As I add new SysEx features to hacktribe I will add functions to that script. I can't give helpful advice on Windows, I haven't used it in over a decade. |

All SysEx messages defined in Electribe 2 Sampler MIDI Implementation. I've added SysEx functions for arbitrary read/write of CPU RAM and flash. The best way to use these is via e2sysex.py. This includes helper functions to get and set data such as groove templates and IFX presets. Writing these to the flash memory will be added in a later update. |

This program uses Electribe sysex: https://github.com/rafamj/elecmidi |

So I've started reading through that sampler midi implementation doc from Korg for a project Im working on and I've run into a few interesting things - I wonder if @bangcorrupt or @rafamj either of you may know about these? First off, the sampler doc is almost identical to the synth one, so pattern data for each part only has a field for "Oscillator Type": Also I can't see anywhere in the Global data dump fields where the oscillator/sample names for each slot number are - I guess Korg didnt bother to include that so @bangcorrupt I wonder if that something you may have access to and perhaps could add as a future sysex request-response, somewhat like you did for IFX? |

I haven't checked but I think you're right about the doc being wrong. The Global Settings sysex dump includes only the things in the Global Settings menu. I can add functions to get the oscillator presets at some point. The new sysex functions I've added all use an arbitrary read/wriite function in the firmware. Selecting specific data and extracting parameters is all done in python. We can use |

Awesome work @bangcorrupt ! I think |

Hello, I have the synth Electribe. When sent a value from 0 to 408 the osc changes accordingly form 1 to 409. For values over 408 the osc type seemingly changes to %408 but the oscilator name displayed changes randomly. I have modified elecmidi to include the parameter oscType. For example one file with the 3 following lines would send the value 217 to oscType of part 1 and change the type to Darbuka1 |

Reporting back to follow up on my own question, it turns out that the docs are just wrong and that user samples in >500 slots are stored in the oscType just fine on the hacktribe firmware. |

If you get buffer overruns or error messages when trying to send pattern files, try installing https://github.com/bangcorrupt/mido and https://github.com/bangcorrupt/python-rtmidi. These will split long sysex messages into 512 byte chunks. Sending other MIDI messages while a split sysex message is transmitting can break transmission. |

Many thanks. I have incorporated this idea to my program, sending 512 byte chunks. It runs without errors when the electribe is stopped, but when it is playing a pattern I still get some errors. |

Thank you for testing. What errors do you get, are they from the OS or the electribe? It may just need smaller chunks, or a longer delay between them. |

I have only put a delay every 512 bytes in my program. It seems that when the electribe is running it has no power to process de data. |
