New Device Request: Elektron Analog RYTM / Four

[RadekPilich]

Starting this "issue" along the lines of the Korg and Akai issues.

I was wondering if anyone has explored / attempted this.

I've found some other github projects deconstructing the sysex, so it might not be so hard to do now, although I'm definitely not competent enough to start this from scratch.

Cool! I think this has most useful information: https://github.com/bsp2/libanalogrytm/blob/master/sysex.h

Looks like quite some work given this is just other code and not really a documentation on how to work with the device, but there seems to be a lot of good information already.

@RadekPilich Here is a very first version for the Analog Rytm, It supports only the Sounds bank for now, to see if it can operate with the synth:

@christofmuc thanks, you are a machine! 😃 I will test both M and RYTM over the weekend.

[RadekPilich]

@christofmuc Error: This synth has not implemented a single method to retrieve a bank. Please consult the documentation!

Connecting via USB, it is visible / auto-detected, running in audio + midi USB mode.

MIDI comms work both ways - KK sees MIDI from RYTM and I can play RYTM from Masterkeyboard.

[christofmuc]

Great, can you show me the MIDI log of the auto detection? I can look why it is not wanting to do the program dump sending.

[christofmuc]

Oh, stupid me, I named a function convertToSingleProgramDump which should have been called convertToProgramDump...

Attached a fix, this should be better!

Yes, that did download the 128 project sounds (sound pool). It just mislabeled as kits in the KK library tree.

What I believe should be the primary interest for us it's the +Drive sound library with 16 banks of 256 sounds (4096 altogether)

[christofmuc]

Ok, what I can tell from the libanalogrytm source code:

#define AR_NUM_KITS (128u)
#define AR_NUM_SOUNDS (128u)
#define AR_NUM_PATTERNS (128u)
#define AR_NUM_SONGS ( 16u)
#define AR_NUM_SETTINGS ( 1u)
#define AR_NUM_GLOBALS ( 4u) /* global slots / settings */

I am seeing codes that can request 128 of each type in the "normal" way, and the same amount as an "x base". I am not sure how to access more data, probably with bank switches? The library doesn't seem to be able to do that.

Here is a more complex version that should allow access to 256 Kits, 256 Sounds, and 256 Patterns (if these even exist). You need to create a new database for these as I changed the numbering scheme of the items.

Hmm, I forgot that it's normally necessary to select the +Drive bank on the device manually before exchanges via Elektron Transfer app. So it might not be fully accessible via MIDI.

That sucks :(

[christofmuc]

Yeah, on some synths you have to activate the memory bank, but then you can normally access it even via MIDI.

I put the version we have into the release 2.5.1. Let me know if there are more open issues, we can reopen this.

[RadekPilich]

Nothing besides patterns and sounds work as far as I can tell.

Only get hundreds of these....

New version which should not throw the errors on the names. Obviously songs and kits have no names stored, or just at a different place. I turned it off for those types.

[RadekPilich]

Patterns don't seem to have names on RYTM. Songs and Kits have names.

Anyways, as I said before, this is unfortunately not really useful, the patches (sound library in the schematic in one of my previous posts) that can be purchased / created and stored on the +Drive are currently not being accessed. And that's the main area of the device where KK could be helpful as librarian.

Everything that is being downloaded currently is the actual project data and while it downloads, I don't think it can be easily send to the device / active project in this partial manner but only as a whole project.

Here is some random video, where uploading of sounds to the +Drive starts at 4:30

Closing this for now.

In the video it seems the Drive+ is behaving more like a USB external drive than a MIDI sysex communication? We could do that of course as well, but that's a different epic.
