Help with Blue

[konsumer]

Hi,
Pardon me, if this is the wrong place to ask, but I have a Electribe2 (blue) that I bought specifically to install hacktribe on, and I can't figure out how to get it working with the new synths + original sounds.

I updated to hacktribe, and it seems to work (I can switch oscillators and they work great) but on standard firmware (2.02 from korg website) it has drums and lots more samples. I want both the new stuff and the old stuff.

If I understand correctly, I need to boot into original firmware, then "EXPORT ALL AUDIO", and manage it in Oe2sSLE, moving it all to 500+, but on device, I see no option to "EXPORT ALL AUDIO" in menu.

Is there another step I need to do?

I'd be happy to write some start-to-finish docs for the blue, if I figure out how to set it up.

I also tried instructions here and get thsi error:

I ran into this one too when trying to extract pcm synth samples. According to this mido issue you seem to have the wrong version of rtmidi installed. You'll need the version with slightly different name called python-rtmidi that is available via pip.

Try to:

• remove rtmidi using pip uninstall rtmidi
• install the version that works with mido: pip install python-rtmidi

This got me around this particular problem.

I sort of got it working without the dump-script, but all the samples are out of order and incorrect (like the saxes are drums.) Here is what I did:

• Load hacktribe firmware for blue (use the header patch option)
• checkout synth-pcm-dump branch
• Get official sampler firmware, patch it
• Install on device
• boot with no SD, plug SD in after it's booted, "EXPORT ALL SAMPLES" (in menu now!)
• Checkout main, patch official sampler firmware
• Update (goes in KORG/electribe sampler not KORG/electribe)
• Now, you have e2sSample.all in Samples/, so offset start index to 500, save & copy that to KORG/hacktribe/Samples and boot

It definitely seems closer, but inspecting that e2sSample.all, it's definitely wrong. Is there any other way to extract this?

The PCM samples from the Synth are not fully supported yet, Hacktribe won't load or dump the multisampled instruments correctly. At boot, the samples are decompressed and sent to the DSP RAM, the synth-pcm-dump branch will also store a copy of the samples in CPU RAM. We can use dump_extracted_pcm.py to copy the samples as a single block via sysex, there isn't a script to cut them up yet. I think the error you get with the script is due to not having python-rtmidi installed (note: rtmidi-python is a different package).

• Install python dependencies and check the script runs.
• Install Hacktribe synth-pcm-dump branch and reboot.
• Run dump_extracted_pcm.py.
• This should give you the synth samples as a single block.
• You will need to manually cut this up and pick the samples you want.
• Install Hacktribe main branch.

Support for the synth samples and custom multisampled instrument is planned for the future.

This totally makes sense. I ended up getting a dump of the samples as WAV files (with extra meta), which seems to be close enough to hear the basic sounds, even though it seems a bit off, still (multilayer, I'm sure.)

I think a related & cool feature would be to allow the new synths to be placed at another offset, so you can keep all the built-in samples and all the demo patterns work. Since I am new to Electribe2, it would be very cool if all the example patterns worked, so I could use the new stuff, but still see the factory demo patterns.
