Reversing the UNO Pro #6

Open mungewell opened 3 years ago

mungewell commented 3 years ago

It seems that the UNO Pro is a least a little similar to the original, obviously the storage size will be a lot bigger. https://cgi.ikmultimedia.com/ikforum/viewtopic.php?f=43&t=27841&p=120259#p120259

The Pro does not respond to the enquiry message: F0 7e 00 06 01 F7

It does respond to the version inquiry: f0 00 21 1a 02 03 12 f7 Response: F0 00 21 1A 02 03 00 12 01 31 2E 30 2E 31 20 23 23 2E 23 23 20 23 23 2E 23 23 00 F7

Interestingly, the Pro emits SysEx when scrolling through presets, like this: F0 00 21 1A 02 03 32 00 01 00 01 F7 F0 00 21 1A 02 03 32 00 02 00 02 F7 F0 00 21 1A 02 03 32 00 03 00 03 F7

When sending something like f0 00 21 1a 02 03 31 f7 which appearently caused the predecessor to dump the current patch, the response of the Pro looks like F0 00 21 1A 02 03 01 31 00 F7

Feeding this one back results in F0 00 21 1A 02 03 01 01 00 F7 Feeding this back results in the same response.

mungewell commented 3 years ago

In the response F0 00 21 1A 02 03 01 31 00 F7 I believe the 01 after the ID is the synth saying 'error'. It does not understand the request... this byte is normally 00 for OK.

This means that the request will need to be 'adjusted'. It could be that the Pro is more like the Drum which separates patches into Kits & Patterns, rather than having 1 item.

You can slowly increase the numbers of bytes (zeros?) you send until the Synth accepts the command, and then figure out what the bytes do.

Another thing to note is that I sometimes saw a response with a lower cmd value - for example CMD 0x33 to change preset would have 0x32 in it's response.

As you saw 0x32 being sent from device perhaps these are async messages, replies without a CMD, I also sees these in my logs from the Drum. Anyhow build confidence that CMD 0x33 is for setting which present is active.

mungewell commented 3 years ago

Next suggestion?

Maybe add same bytes from 0x32 to CMD 0x33... ie select patch 5 with $ amidi -p hw:1,0,0 -S 'f0 00 21 1a 02 03 33 00 05 00 05 f7'

Maybe the two vales are patch & sequence pattern?

mungewell commented 3 years ago

Noted the Drum replies (0x32) in double bytes, so maybe the Pro just uses 2 bytes for selecting preset $ amidi -p hw:1,0,0 -S 'f0 00 21 1a 02 03 33 00 05 f7'

Yes... Pro has 256 presets, so it MUST use 2 bytes. Note Midi is 7 bit, so 01 00 would be preset 128.

Hello from the future! I'm interested in working on reverse engineering the Uno Pro spec assuming it's not been done yet. The data in this thread is about two years old: does anyone know if further progress has been made? Such as identifying the patch-request sysex command?

mungewell commented 1 year ago

Hi @SeanLuke personally I never got my hands on a Pro, so haven't done any real investigates. Above was from discussion with another user...

Willing to offer any help/encouragement I can.

SeanLuke commented 1 year ago

Okay, here's what I have ascertained at first glance.

REQUEST PATCH NAME: [Patch names are for some reason independent of patches]

F0 00 21 1A 02 03 24 01 BANK PATCH F7

RESPONSE:

F0 00 21 1A 02 03 24 01 BANK PATCH NAME... ZEROS... F7

NAME... is a non-zero-terminated string of UP to 14 characters, followed by enough zeros to make the entire message 43 bytes long.

WRITE PATCH NAME:

F0 00 21 1A 02 03 23 01 BANK PATCH NAME... F7

NAME... is a non-zero-terminated string of UP to 14 characters.
Thus this message varies in length up to 25 bytes.

REQUEST CURRENT MEMORY:

F0 00 21 1A 02 03 37 00 00 F7

RESPONSE:

F0 00 21 1A 02 03 00 37 00 00 BANK PATCH BANK PATCH DATA... F7

DATA... is 294 bytes long. It appears to be a simple parameter byte encoding. It does seem that the Bank and Patch appear twice

WRITE PATCH:

F0 00 21 1A 02 03 28 BANK PATCH DATA... F7

DATA... is 294 bytes long. It appears to be a simple parameter byte encoding. Patches do not include their names (ugh)

At present I don't know how to request a patch (other than doing a PC, then requesting from current memory, which is suboptimal).

REQUEST PATCH CHUNK: [ Unknown Function. This happens when copying a preset in the librarian but why I don't know ]] 

F0 00 21 1A 02 03 29 BANK PATCH CHUNK F7

CHUNK goes 0...4

RESPONSES: [To each chunk request]

F0 00 21 1A 02 03 00 29 BANK PATCHNUM CHUNK DATA... F7 [checksum unknown]

Chunk 0 is 305 bytes total Chunk 1 is 204 bytes total Chunk 2 is 223 bytes total Chunk 3 is 209 bytes total Chunk 4 is 209 bytes total This appears to be a grand total of 1090 data bytes! Why does it need this?

SETTING PARAMETERS: Parameters are both sent to and received by the device. Most parameters are set by CC, see IK's "Midi Chart".
The following appear to be set by Sysex instead.

mungewell commented 1 year ago

Okay, here's what I have ascertained at first glance.

That's some pretty awesome info!

It might be helpful to identify/hilight the 'CMD' byte(s), and if you haven't noticed the response appears to include a 'error' byte (00 is Good, 01 is Bad command). I was able to use this to manually search for other commands.

REQUEST CURRENT MEMORY:

F0 00 21 1A 02 03 37 00 00 F7

RESPONSE:

F0 00 21 1A 02 03 00 37 00 00 BANK PATCH BANK PATCH DATA... F7

DATA... is 294 bytes long. It appears to be a simple parameter byte encoding. It does seem that the Bank and Patch appear twice

Perhaps it's telling you the [current patch], followed by the [patch] for the data. For the original the data was a [count] of the parameters, followed by each [parameter, type, value].

Note: SysEx/Midi is 7bit, so two bytes is actually 128 * 128 max value.

DATA... is 294 bytes long. It appears to be a simple parameter byte encoding. Patches do not include their names (ugh)

Can you provide a hexdump/example?

At present I don't know how to request a patch (other than doing a PC, then requesting from current memory, which is suboptimal).

Did you try replacing the 00 00 in the command? Original had different CMD for current (0x31) vs specific (0x24).

Chunk 0 is 305 bytes total Chunk 1 is 204 bytes total Chunk 2 is 223 bytes total Chunk 3 is 209 bytes total Chunk 4 is 209 bytes total This appears to be a grand total of 1090 data bytes! Why does it need this?

Why is this more data than the 'request current patch'? Do you see the same data structures? Perhaps into also includes sequencer info.

SETTING PARAMETERS: Parameters are both sent to and received by the device. Most parameters are set by CC, see IK's "Midi Chart". The following appear to be set by Sysex instead.

Note: I found that the SysEx setting of parameters allowed for finer resolution.

F0 00 21 1A 02 03 11 01 05 F7 [unknown purpose]

CMD 0x11 used to enter device mode?

F0 00 21 1A 02 03 21 00 1D VAL F7 0 ... 14 for scales in order

CMD 0x21 write setup parameter?

F0 00 21 1A 02 03 33 00 02 F7

CMD 0x33 = switch to preset?

SeanLuke commented 1 year ago

Some more. When SONG is pressed, this unknown command is emitted by the machine:

F0 00 21 1A 02 03 27 00 15 01 F7

Then this unknown command is emitted

F0 00 21 1A 02 03 32 00  01 00 01 F7

Can you provide a hexdump/example?

Sure. After loading patch 0 bank 0 into memory, here's the current memory dump:

I note that these chunks have different lengths (at least chunks 1-4) than described earlier. I can't explain that.

Did you try replacing the 00 00 in the command? Original had different CMD for current (0x31) vs specific (0x24).

Yeah. I'm guessing that chunk 00 is the patch data.

SeanLuke commented 1 year ago

More.

Why is this more data than the 'request current patch'? Do you see the same data structures? Perhaps into also includes sequencer info.

It appears to be the same structure. So chunk 0 is probably the patch data.

Note: I found that the SysEx setting of parameters allowed for finer resolution.

Thing is, the unit emits CC, and the editor also emits CC. And you're right, they're not fine enough! But I don't know what the sysex equivalents should be.

Also this appears to be NAK:

F0 00 21 1A 02 03 01 COMMAND  UNKNOWN F7

UNKNOWN varies: it might be the remaining bytes in the original message? Not clear.. COMMAND is in response to your particular command. So if you sent something like

F0 00 21 1A 02 03 29 00 00 05 F7

["Request Chunk #5 from patch 0 bank 0" -- there is no chunk #5]

You'd get back:

F0 00 21 1A 02 03 01 29  03 F7

On the original you could use the 'write current patch' (CMD 0x30), but only send one (or a few) parameters/values.

$ amidi -p hw:1,0,0 -S 'f0 00 21 1a 02 01 30 00 01 20 22 00 03 f7'
                                                         ^^ ^^ Param Value 
                                                   ^^ ^^ Param ID/Type
                                                ^^ Param count

Also this appears to be NAK:

F0 00 21 1A 02 03 01 COMMAND  UNKNOWN F7

Yep, 01 in response (before CMD) tells you it didn't understand. Like I said you can use this to fuzz for new commands.

mungewell commented 1 year ago

Can you provide a hexdump/example?

Sure. After loading patch 0 bank 0 into memory, here's the current memory dump:

0000  F0 00 21 1A 02 03 00 37  00 00 00 00 00 00 01 00  |  !    7        |

As you note this is similar format to that from "Chunk 0".

It doesn't really look like Original's format, which was a sequence of parameters/values. as described here: https://github.com/mungewell/uno-synth-utils/blob/master/uno_synth.py#L46

For the UNO Drum they implemented some really weird stuff, and this made it hard to understand what was what.... if you change a single parameter slightly, does that change show in hexdump? Does change in data make logical sense...

The 0x3F is very suspicious.

Midi/SysEx is only 7bit, I've seen multiple different devices pack 8bit data into 7bit to send across Midi. You may need to unpack 7bit->8bit before the patch data makes sense,

Examples: https://github.com/mungewell/zoom-zt2/blob/master/zoomzt2.py#L236 https://github.com/mungewell/circuit_samples/blob/main/circuit_samples.py#L39 https://github.com/mungewell/twinlooper/blob/main/twinlooper.py#L67

Are you able to save a patch (from the editor) to hard-disk? What format does that have?

Christedge commented 1 year ago

Hi all, here's »Above was from discussion with another user« :) . Thanks for sharing your findings. I was able to request patch names from my Pro. I also was able to fetch "current memory" by F0 00 21 1A 02 03 37 00 00 F7. Did you have any luck requesting a particular preset (or even request all presets) in order to do a backup?

Christedge commented 1 year ago

I now have the editor running on a Mac as well as MIDI monitor. When pressing "Get" in the editor, the Uno Synth Pro sends all 256 preset names as SysEx. 256 preset names.syx.zip

Christedge commented 1 year ago

When I select all presets on the Uno Synth Pro in the editor window and press "TO LIB" (which means dumping all presets to the Mac), the Uno transmits 1280 SysEx messages of different sizes, potentially 5 per preset. 1280 SysEx messages, potentially 5 per preset.syx.zip

Christedge commented 1 year ago

When I try to fetch presets 1 by 1, e.g. Preset 1, then preset 2, then 3 and then 4, the Uno always sends 5 SysEx messages. However, the length of those messages differs per preset, see hardcopy attached. At least the first one always consists of 305 bytes. Presets 1 through 4

jounih commented 2 months ago

any updates on this? would love a CTRLR panel for the uno pro

Christedge commented 2 months ago

Didn't work with my Uno since then, so no news at my end.

ce

Christedge commented 5 days ago

On my Mac, I can listen to the SysEx communication between the editor and the Uno Synth Pro. HOwever, it's always multiple SysEx packages and my time and skills are limited to understand the meaning of them.

Christedge commented 5 days ago

BTW: The editor uses both MIDI CC (e.g. filter cutoff) and SysEx messages (e.g. mod matrix) to communicate with the hardware.
