 -Position
 -Possible value range

-There seems to be two possible ways to figure that out.
+There seems to be three possible ways to figure that out.
 1) Use USB sniffer together with X-Edit
   Once you set up X-Edit and usb sniffer, set some option.
   USB sniffer should report something like this being sent to device:
   (all numbers here are hex)
   04 F0 00 00 04 10 00 5E 04 02 41 00 04 30 09 00 07 00 34 F7

-   To get SysEx command out of it, remove every 4th byte, so we have:
+   MIDI data is transferred over USB using 32-bit USB-MIDI Event Packets.
+   Byte 0 is Cable Number (high nibble) and Code Index Number (low nibble).
+   Bytes 1, 2 and 3 are data.
+   Every bulk transfer on USB MIDI endpoint contains atleast one such packet
+   (those are sent one after each other).
+   In case of Digitech devices, the Cable Number seems to be 0 (correct me,
+   if I'm wrong).
+   There are three different Code Index Numbers that are being used in this
+   particular case:
+   0x4 - SysEx starts or continues (Byte 1, 2 and 3 from this packet are
+         part of our MIDI message)
+   0x5 - SysEx ends with following single byte (we just need to take Byte 1
+         from this packet)
+   0x6 - SysEx ends with following two bytes (we just need to take Byte 1 and 2
+         from this packet)
+   0x7 - SysEx ends with following three bytes (we need to take Byte 1, 2 and 3
+         from this packet)
+
+   Unused bytes in USB-MIDI packets are supposed to be 0.
+
+   To get SysEx command out of it, apply above rules, so we have:
      F0 00 00    10 00 5E    02 41 00    30 09 00    00 34 F7

   SysEx message format seems to be formed like this:
-   magic bytes - F0 00 00 10 00 5E 02 41
-   status byte - in this example 00
+   SysEx start byte - F0
+   Manufacturer ID - 00 00 10
+   Device ID - 00
+   Family ID - 5E (RP)
+   Product ID - 02 (RP250)
+   Procedure - 41 (see MessageID in gdigi.h) 
+
+   As MIDI messages must not contain bytes with MSB bit set, Digitech
+   devices use packing system.
+   First byte contains MSB bits from following 7 bytes (this scheme
+   continues as many times as needed) (see pack_data() and unpack_message() in
+   gdigi.c for details).
+
+   Assuming message has been unpacked, the meaning of next bytes:
   ID - in this example 30 09
   Position - in this example 00
   Value - in this example 00 (can be more bytes long, see below)
-   Checksum - to calculate it, XOR all bytes, and then XOR it with 07
+   Checksum - to calculate it, XOR all bytes (of packed message)
   Every message ends with F7

-   Status byte bits explained:
-      7th - ???
-      6th - if active add 80 to ID
-      5th - ???
-      4th - is active when value will start with length
-            In such case value can be something like:
-              01 12 or 02 12 34 or 03 12 34 56
-            and proper values are:
-              01 - 12
-              02 - 1234
-              03 - 123456
-      3rd - when 4th bit is also active, and first value byte is 01
-            then add 80 to value
-      2nd - when 4th bit is also active, and first value byte is 02
-            then add 80 to value
-      1st - when 4th bit is also active, and first value byte is 03
-            then add 80 to value
-
   So for above example:
   ID = 3009 (hex) = 12297 (decimal)
   Position = 0

       save new patch
       check patch file and note the change
     while you don't have all possible values
+3) Use gdigi
+   After starting gdigi turn the knobs on your device.
+   Check out console output, you should notice something like this:
+      ** Message: Received parameter change ID: 210 Position: 4 Value: 0
+   ID is ID, Position is Position and Value is one of possible values.
+   To get all possible values keep turning knobs and watch the output.
+   If you change effect type usually there's more messages - where,
+   usually the first one is type change, and rest are default values.
+   This way you *CANNOT* gather all information (there're X-Edit only
+   controlled values, check device manual for more information).

Tim LaBerge	35e42dc653	Detect DigiTech devices on startup. If more than one device is found, ask user which one to use.	2012-03-26 16:17:03 +02:00
Tim LaBerge	ce296d2698	1) Require libxml-2 and build new file preset_xml.c 2) In effects.c, some EffectsValues are changed to better reflect the strings used in the XML. 3) New EffectSettings are added for use when writing out effects to XML. 4) Added an XmlLabel structure for mapping a value to a string. Generally, these are the union of the set of all values over the set of supported devices. 5) There's a large array of XmlSettings used to derive the translation of a preset to XML. 6) Add an enum for product_id and use it to set a filter for file suffix. 7) Minor cleanup in push_message() that suppresses spurious error messages. 8) Fixed a bad memset in read_data_thread(). 9) In gdigi.h, a few changes in names to be consistent with XML. There are some new definitions of LFO and VSWITCH parameters that need to be computed. 10) In gui.c, fixed up a compiler warning. Added a map from device id to file type and code to set a default filter in the read dialog. Wired up the 'save to XML' callback and reorganized the menue entries to better distinguish between 'save to file' and 'store to device'. In preset.c, sort the params so that what we write as XML more closely matches what is generated on the windows side.	2012-03-26 22:08:29 +08:00
