ZOOM MS-50G/60B/70CDR MIDI Mesasges

This is a non-official document based on a personal and non-strict experiments.

Short messages

Patch Select

[0xc0,pp] : Program Change

Select a patch. pp=patch number (0-49)

Tuner Mode On/Off

[0xb0,0x4a,mm] : Control Change CC#74

Tuner Mode On/Off. mm<64:off, mm>=64:on

System Exclusives

Identity Request

[0xf0,0x7e,0x00,0x06,0x01,0xf7] : Identity Request

This is a MIDI Universal System Exclusive message, 'Identity Request'. returns ID code and version number, Bytes 10-13 represents firmware version.

MS-50G : [0xf0,0x7e,0x00,0x06,0x02,0x52,0x58,0x00,0x00,0x00,0x33,0x2e,0x30,0x30,0xf7] productID = 0x58, version="3.00"
MS-60B : [0xf0,0x7e,0x00,0x06,0x02,0x52,0x5f,0x00,0x00,0x00,0x31,0x2e,0x30,0x30,0xf7] productID = 0x5f, version="1.00"
MS-70CDR : [0xf0,0x7e,0x00,0x06,0x02,0x52,0x61,0x00,0x00,0x00,0x31,0x2e,0x30,0x30,0xf7] productID = 0x61, version="1.00"

In following exclusive messages, 4th byte (0x58) is for MS-50G. it should be (0x61) or (0x5f) for MS-70CDR/MS-60B.

Send Patch

[0xf0,0x52,0x00,0x58,0x28,effect1,effect2,...,(effect5),(effect6), patch-name,0xf7] (50G/70CDR:146bytes, 60B:105bytes)

Write 146bytes/105bytes patch-data to current program. It consist of effect1-6 or effect1-4 parameters and patch-name. Details are described later.

Request Patch

[0xf0,0x52,0x00,0x58,0x29,0xf7]

Request patch-data of current program. it returns 146/105 bytes patch-data (same as Send Patch command)

Parameter Edit

[0xf0,0x52,0x00,0x58,0x31,nn,pp,vvLSB,vvMSB,0xf7]

Parameter value edit. nn=effect#(0-5) pp=param#(0-10) vv=value. It seems effective only for effect1-3
value range is depends on each effect.

pp=0 : switch Effect/Bypass vv=0:off / vv=1:on.
pp=2 : page1-knob1
pp=3 : page1-knob2
.
.
pp=10: page3-knob3

Store Patch

[0xf0,0x52,0x00,0x58,0x32,0x01,0x00,0x00,pp,0x00,0x00,0x00,0x00,0x00,0xf7]

Force store to memory. pp is patch#(0-49). Message [Storing...] is displayed

Request Current Program

[0xf0,0x52,0x00,0x58,0x33,0xf7]

Request current bank & program. The device returns bank select and program change :
[0xb0,0x00,0x00, 0xb0,0x20,0x00, 0xc0,pp]
here the pp=program#(0-49). This is MIDI bank select and program change messages (bank = always 0) .

Parameter Edit Enable

[0xf0,0x52,0x00,0x58,0x50,0xf7]

Parameter value edit enable. This is needed before Parameter Editing.

Parameter Edit Disable

[0xf0,0x52,0x00,0x58,0x51,0xf7] Parameter value edit disable.

??? :

[0xf0,0x52,0x00,0x58,0x60,0xf7]

Not yet sure

Patch Data Format

Patch-data is MIDI system exclusive data. It starts with F0 and ends with F7

146bytes MS-50G/MS-70CDR
105bytes MS-60B

consist of :

F0 52 00 (devid) 28.. eff1 eff2,... (eff5 eff6) patchName F7

here the devid is:
0x58 MS-50G
0x5F MS-60B, (eff5,eff6) is not exist
0x61 MS-70CDR

eff1 to eff6 include the on/off state, type of each effect, parameter values. bit arrangement is scrambled rather than fixed format.

In the following table, the notation like '1p2b3' means :
[Effect number(0-5)] p [Parameter number(0-8)] b [bit(0-7)].
0cab ... Seems a special byte used in AMP cabinet model
0x00 if "OFF"
0x50 v1 B-AMP (SVT - MarkB)
0x51 v2 B-AMP (SMR - Heaven)
0x40 G-AMP
(this is depends on CAB setting, not for effect type)

0v ... Also a special bit for B-AMP? it is ON if the effect is ver2 B-AMP
(this is for effect type, not for CAB setting)

Other notation means :
0t ... Effect1 Type Bits
0EfOn ... Effect1 On/Off
c0 ... Current Effect Focus 6-n => 0-5
n0 ... Max Effect Number
df0 ... DSP full bits
N0-N9 ... Patch Name (max 10char)
tt0-7 ... Tap Tempo
