+DSP - for amplifier it is always 5
+mod - amplifier model; different for each emulated amp
+vol - volume
+gai - gain
+ga2 - gain 2
+mvl - master volume
+tre - treble
+mid - middle
+bas - bass
+prs - presence
+dep - depth
+bis - bias
+number - don't know what this is; different for each emulated amp
+ng - noise gate; value 0x00 - 0x05
+ths - threshold; value 0x00 - 0x09
+cab - cabinet; value 0x00 - 0x0c
+sag - sag; value 0x00 - 0x02
+bri - brightness; value 0x00-0x01
+?? - values which I haven't decoded yet; different for each emulated amp
+
+After packet with data described above you have to send a packet which will tell the amp to actually apply the settings. This packet have zeroth byte set to "0x1c", first to "0x03" and all other to "0x00".
+4. Setting and clearing effects
+
+Data format for setting an effect is:
+
+     0                                       1
+     0   1   2   3   4   5   6   7   8   9   0   1   2   3   4   5
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+00 | 1c| 03|DSP|     00    | 01| 01|               00              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+16 |fxm| 00|slt| ??| ??| ??|                   00                  |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+32 |kb1|kb2|kb3|kb4|kb5|kb6|                   00                  |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+48 |                               00                              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+
+DSP - can be either 6, 7, 8 or 9; depends on effect familly
+fxm - effect model; independent for each effect
+slt - slot; before amp have numbers from 0 to 3, after from 4 to 7
+kb1, kb2, kb3, kb4, kb5, kb6 - knobs values; not every time all are used; maximum
+  value of the knob depends on the effect
+?? - some strange numbers specific for each effect
+
+If you want to remove the effect send normal effect-setting packet but set "effect model" and knobs fields to zeros.
+I haven't tried what happens if you send such packet to DSP 0x05.
+"Execute" command for both setting and clearing the effect is the same as for the amp setting.
+5. Saving settings on amplifier
+
+Saving settings is very easy since you don't have to transmit all the settings which you want to store. You only send a command containing slot number and name for a preset. Data are taken directly from DSPs.
+Packet format is:
+
+     0                                       1
+     0   1   2   3   4   5   6   7   8   9   0   1   2   3   4   5
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+00 | 1c| 01| 03| 00|SLT| 00| 01| 01|               00              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+16 |                              name                             |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+32 |                              name                             |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+48 |                               00                              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+
+SLT - memory bank to which to save settings; value 0x00 - 0x17
+name - name of the preset ended with "\0"; if not all fields are used used the rest
+  is set to 0x00
+
+Fender FUSE after saving settings chooses memory bank it just saved. PLUG also does this.
+6. Choosing memory bank
+
+"Choose memory bank" command looks like this:
+
+     0                                       1
+     0   1   2   3   4   5   6   7   8   9   0   1   2   3   4   5

+Technicalities
+
+Here I want to put all the info I have about how Mustang amp works
+under the hood.
+
+Table of contents
+
+    Overview
+    Connecting
+    Setting amp
+    Setting and clearing effects
+    Saving settings on amplifier
+    Choosing memory bank
+    Captured data 
+
+1. Overview
+
+It has five DSPs. One for each effect family and one for amplifier
+emulation. DSPs are addressed from 5 to 9. I don't know why first five
+addresses are omitted and if this means anything.  DSPs with their
+functionality are as follows:
+
+    0x05 - amplifier emulation
+    0x06 - stompbox effects
+    0x07 - modulation effects
+    0x08 - delay effects
+    0x09 - reverb effects
+
+    I also have found packets with device address 0x0a but don't know what this is.
+
+2. Connecting
+
+All the transmission between program and amplifier is using USB
+interrupt transfer. Endpoint to which you want to send data is 0x01
+and USB interface which you want to claim is 0x00. If you want to
+receive data from amplifier use endpoint 0x81.
+
+Each packet carries 64 bytes of data.
+
+When connecting you should send two packets to the amp and get
+response for each of them. First should have value "0xc3" set on the
+first position (counting from zero) and second values "0x1a" and
+"0x03" on zeroth and first position.
+
+After that a packet asking for amp's settings is send. The packet is
+of form "0xff" on zeroth and "0xc1" on first position. Amplifier
+responds to that sending:
+
+    names of all presets in the form:
+
+        packet with name in a form: values "0x1c 0x01 0x04" as first
+        three bytes, then slot number on forth byte and name encoded
+        in ASCII on 32 bytes starting from sixteenth
+
+        packet with two first bytes and forth (slot of the preset) the
+        same as in name packet
+
+    current state of the amp in the form:
+
+        name of the current preset in the form as described above
+
+        amplifiers setting in the form the same as when setting
+        amplifier's settings (below) except that first byte is not
+        "0x03" but "0x01" and preset number encoded on the forth byte
+
+        settings of four effects as described below with the same
+        change to the first byte as in amplifier's settings and preset
+        number encoded on the forth byte
+
+        setting of some mysterious device with address "0x0a"
+
+        confirmation packet same as in preset names 
+
+    names with settings of all presets on the Mod and Dly/Rev knobs
+    (first all settings for Mod knob then all settings for Dly/Rev
+    knob) in the form:
+
+        name of the preset in the form: values "0x1c 0x01 0x04" as
+        first three bytes, value "0x01" for Mod or "0x02" for Dly/Rev
+        knob on third position, slot number on forth position (counted
+        from zero), name encoded in ASCII on 24 bytes starting from
+        sixteenth byte
+
+        settings of the effect in the same form as for setting the
+        effect (below) except that first byte is "0x01" not "0x03" and
+        preset number encoded on the forth byte
+
+        This packet is set only when sending Dly/Rev presets Dly/Rev
+        knob hold settings for two effects so the next packet carries
+        info about second effect, if effect is not set the packet have
+        the same form as packet for clearing effect except that first
+        byte is "0x01" not "0x03" and preset number encoded on the
+        forth byte
+
+        confirmation packet with values "0x1c 0x01" on zeroth and
+        first byte, "0x01" or "0x02" depending on the knob on third
+        byte and preset number encoded on the forth byte
+
+Wireshark file with whole initialization communication can be found here.
+
+3. Setting amp
+
+Format of data for setting amp is as follow:
+
+     0                                       1
+     0   1   2   3   4   5   6   7   8   9   0   1   2   3   4   5
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+00 | 1c| 03|DSP|     00    | 01| 01|               00              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+16 |mod|                         00                                |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+32 |vol|gai|ga2|mvl|tre|mid|bas|prs|?? |dep|bis|?? |   number  |ng |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+48 |ths|cab|?? |sag|bri| 01|?? |               00                  |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+
+DSP - for amplifier it is always 5
+mod - amplifier model; different for each emulated amp
+vol - volume
+gai - gain
+ga2 - gain 2
+mvl - master volume
+tre - treble
+mid - middle
+bas - bass
+prs - presence
+dep - depth
+bis - bias
+number - don't know what this is; different for each emulated amp
+ng - noise gate; value 0x00 - 0x05
+ths - threshold; value 0x00 - 0x09
+cab - cabinet; value 0x00 - 0x0c
+sag - sag; value 0x00 - 0x02
+bri - brightness; value 0x00-0x01
+?? - values which I haven't decoded yet; different for each emulated amp
+
+After packet with data described above you have to send a packet which
+will tell the amp to actually apply the settings. This packet have
+zeroth byte set to "0x1c", first to "0x03" and all other to "0x00".
+
+4. Setting and clearing effects
+
+Data format for setting an effect is:
+
+     0                                       1
+     0   1   2   3   4   5   6   7   8   9   0   1   2   3   4   5
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+00 | 1c| 03|DSP|     00    | 01| 01|               00              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+16 |fxm| 00|slt| ??| ??| ??|                   00                  |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+32 |kb1|kb2|kb3|kb4|kb5|kb6|                   00                  |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+48 |                               00                              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+
+DSP - can be either 6, 7, 8 or 9; depends on effect familly
+fxm - effect model; independent for each effect
+slt - slot; before amp have numbers from 0 to 3, after from 4 to 7
+      kb1, kb2, kb3, kb4, kb5, kb6 - knobs values; not every time 
+      all are used; maximum value of the knob depends on the effect
+?? - some strange numbers specific for each effect
+
+If you want to remove the effect send normal effect-setting packet but
+set "effect model" and knobs fields to zeros.  I haven't tried what
+happens if you send such packet to DSP 0x05.
+
+"Execute" command for both setting and clearing the effect is the same
+as for the amp setting.
+
+5. Saving settings on amplifier
+
+Saving settings is very easy since you don't have to transmit all the
+settings which you want to store. You only send a command containing
+slot number and name for a preset. Data are taken directly from DSPs.
+
+Packet format is:
+
+     0                                       1
+     0   1   2   3   4   5   6   7   8   9   0   1   2   3   4   5
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+00 | 1c| 01| 03| 00|SLT| 00| 01| 01|               00              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+16 |                              name                             |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+32 |                              name                             |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+48 |                               00                              |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+
+SLT - memory bank to which to save settings; value 0x00 - 0x17
+
+name - name of the preset ended with "\0"; if not all fields are used
+  used the rest is set to 0x00
+
+Fender FUSE after saving settings chooses memory bank it just
+saved. PLUG also does this.
+
+6. Choosing memory bank
+
+"Choose memory bank" command looks like this:
+
+     0                                       1
+     0   1   2   3   4   5   6   7   8   9   0   1   2   3   4   5
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
+00 | 1c| 01| 01| 00|SLT| 00| 01|                 00                |
+   +---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
