G2 USB messages

Updated 18-9-2011 Bruno Verhue

Overall remarks/findings

The host software (clavia pc software) starts with asking the complete current state of the G2 in the "Start up sequence"
After that it indicates to the G2 that it is ready to receive operational messages from the G2.
These messages contain for example the data for the volume indicators that are shown on some modules .
When knobs are turned on the G2, i expect that these will result in messages from the G2 tot the host.
Also when the G2 resceives sysex or cc midi messages.
When modules or cables are added to or deleted from the patch in the host software, it does not send the complete new patch over to the G2 but a much smaller message.
This message contains just enough information to modify the patch data that the G2 holds internally so that matches the patch data that the host software holds.
The G2 keeps track of the patch version in a slot by a counter. Each time a new patch is loaded after the start up sequence, this counter is increased. Maybe this has to do with the possibility to change patches with sysex, but i haven't checked that yet.
When you want to make a change to a patch or parameter from the host, you have to send this version counter with the command.
I also noticed that when patches that are downloaded from the G2 by the usb interface, they have 10 variations in stead of 9 (8 + init).
The send messages contain a main command code indicating that it is a system command (0xc) or a slot command (0x8 + slot) and a sub command code. The response messagealways has the main command code and sometimes the sub command code plus or minus 1. Haven't found the rule to this yet.

How to read the messages

From https://github.com/msg/g2ools g2ctl.py

Updated 23-8-2011

Send message

Message send from PC to G2

Messages are sent formatted as bytes:
SS SS MM MM MM .. MM CC CC
SS: Big endian 16-bit size of message
MM: Message (variable length)
CC: Big endian 16-bit crc of MM MM .. MM

Then the message itself (MM MM ..MM):
Messages start with 0x01 0xRC 0xDD 0xDD .. 0xDD
C: command (usually just the lower nibble)
R: 0x2 when request, 0x0 for response
0x3 ? maybe response-less request
DD: data for command

Interrupt message

Interrupt messages are send from G2 to PC
It can contain the compleet reply when it fits in 16 bytes else it contains the length of the extended message.

Message structure:
0xLT 0xRT 0x0C 0xVV 0xSC 0xDD 0xDD .. 0xDD 0xCC 0xCC (16 0xDD bytes)

L: embedded message length (<=0xf, always zero for extended message)
T: type: 2 embedded message, 1 extended message
RT - Response type
0C - The command the message responds to
VV - Version
SC - Sub command
DD - Data
CC - Checksum

Extended message

These are the longer replies:

Message structure:
0xRR 0x0C 0xVV 0xSC 0xDD .. 0xDD 0xCC 0xCC

RT - Response type
0C - The command the message responds to
VV - Version
SC - Sub command
DD - Data
CC - Checksum

The following table shows examples of response messages.

This seems to be soms sort of universal aknoledgement message like "ok"

When the initialization part is done the clavia software sends the same message as this one, with 00 in stead of 01. Then you see messages comming through from the G2 to the clavia software. Some of these messages are volume indicator values.

When you send this message with value 01 the G2 stops sending messages.

Get patch or performance version counter

Example:

Send message

000000 - 00 09 01 2C 41 35 04 42 54 ...,A5.BT

Each time a patch is loaded in a slot, the version number is increased. So when a command for a particular patch is send to G2, it checks if the patch in the slot is still the same. (You have to send the version no with the command).

You get the same respons with a new version counter if you load a patch with usb.

The init message resets the version numbers.

CRC	2 Bytes	Checksun

This message probably contains a table, with how much of the available recourses are currently in use in the VA section.

With this table the software can check if there are enough recources available to add a particular module.

Resource could be cycle times, memory or delay memory or something like that.

Every module has a kind of fingerprint of how much of each resource it needs.

So at a particular stage you might not be able to add module x, because it would overflow the memory, but you still can add module y, that uses more cycles but
less memory.

Probably with this, the totals "Cycles" and "Memory" that are shown in the software are calculated.

The response probably is the parameter that is focussed on the G2 display.

In the example this would be Location 02 : patch settings, Module 01 : patch, Parameter 00. Can't check it because i only have an engine.

Then come the other 3 slots...

Basically the same as above.

The meaning of the field "IsLed" is yet unknown.

I understand that Uprate means that the module goes in higher processing mode when modulated by audio. So it's a property of the module that depends on how it is patched. Maybe Isled has also some meaning like that.

After this a messages is send from the host to the G2. This probably sets the focus of the G2 display on the inserted module. It looks a bit similar with the Get focussed parameter message.

After adding a module the G2 sends to the host the updated resources used table, message Resources used VA or Resources used FX for the location the module was put in and for each slot.

The host also sends the message Unknown 6 for each slot.

Adding a Cable

Examples

Add cable from Noise (ModID=1, connector type = 1(out), ConID = 0) to 2Out (ModID=2, ConType = 0(in), ConID = 1)

00 0D 01 28 00 50 18 01 40 02 01 E5 28

Add cable from Noise (ModID=1, ConType=1, ConID=0) to Mix4B (ModID=2, ConType = 0, ConID=3) -> module Mix4B gets uprated

00 11 01 28 00 50 18 01 40 02 03 2a 01 02 01 4d dd

Here an example where i first made a chain of Mix4B modules, alle cables are blue, then i connect a noise module to the first Mix4b in the chain-> all Mix4b's get uprated and all cables turn red

00 2f 01 28 00 50 18 05 40 01 03 2a 01 01 01 54 08 02 03 01 40 2a 01 02 01 54 08 04 01 02 40 54 08 03 03 04 01 2a 01 03 01 2a 01 04 01 7c bd

Before connecting noise, all cables are blue.

After connecting noise, all cables are red, modules in chain are uprated

So the usb message for adding a cable looks like the following:

It is also important to keep the right order for the modules in the cable connection, when i put the 2-out as the "from" module and the noise as the "to" module, the clavia software
gives an eror like:

"Version corrupted: Connector does not exist"

After adding a cable the G2 most of the time sends to the host the updated resources used table, message Resources used VA or Resources used FX for the location the module was put in and for each slot. Somethimes it does not, but then the clavia software makes a request for the resources used table.

The host also sends the message Unknown 6 for each slot.

Delete module

In the example a module with one cable is deleted. The send contains first a message to change the cable color to white, then to delete the cable and finally to delete the module.
So basically you have to delete alle the cables first and then delete the module.

Messages from G2 to Host

The G2 sends messages to the host on it's on initiative, when tthis is enabled by the host with message Start communication to host.

Resources used messages

When something in a patch is changed, for example a module added or a cable deleted and so on, the G2 sends the updated resources in use table for each slot.

This is the same message that is received in response to the Resources in use message in the start up sequence.

Example

01 00 00 72 01 00 0d 00 07 02 00 00 00 04 00 02 00 0d 00 00 00 01 00 07 00 00 00 00 00 00 00 00 72 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 57 54

Volume indicator data

When there are modules with a volume indicator in a particular slot, the G2 sends the following kind of messages:

01 00 00 3a 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 38 b1

01 03 00 3a 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0a b0

In this case there's a patch in slot A and D and slot B anc C are empty;

It seems that in this message two bytes are reserved for each volume indicator and the position in the message corresponds to a particular module. I don't know yet how this position relates to the module id.

When a noise is connected to the an input of a Mix4b module the message changes in

01 00 00 3a 00 06 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ea 22

then when de mix is connected to a 2Out the message chages in

01 00 00 3a 00 06 00 06 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 91 11

When the volume knob on the mix module is opened up, these change in:

01 00 00 3a 00 07 00 07 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 52 be

And closing the volume controle:

01 00 00 3a 00 02 00 02 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 af ce

Appendix : Sequence of messages when making a patch

Another almost complete sequence of messages, i only left out some of the volume indicator data messages.

2Out, Mix4B, FltClassic, Noise

Example patch 1

Connect Mix4b Out to Modulation input FltClassic
Connect Noise to Mix4B in => so fltclassic and mix4b should be uprated in one go.

Add module 2-out:
