GM/GS/XG system exclusive messages and controllers default values

I would like to know which controllers/NRPN/RPN, etc are reset when midi stream/file send a sysex message to reset synth system to GM/GS/XG; and then for each controller which reset value is assigned to.

I would also like to kwow which controllers are reset by "Reset All Controllers" controller change MIDI message (cc 121).

I think that depends on BASSMIDI library implementation.

This info would be very useful when creating/editing a MIDI file.

Thnak you.

For all the supported reset SysEx messages (GM/GM2/GS/XG) it is true that all controllers and all RPN/NRPN values are reset to default (also programs/instruments are reset to default). According to my results these are the default values for controllers 0-127:

    0, 0, 0, 0, 0, 0, 2, 100 {Volume}, 64 {Balance}, 0, 64 {Pan}, 127 {Expression}, 0, 0, 0, 0,
    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
    0, 0, 0, 0, 0, 0, 0, 64, 64, 64, 64, 64, 64, 64, 64, 0,
    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 40 {Reverb}, 0, 0, 0, 0,
    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0,
    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0

Contrary Reset All Controllers (CC# 121) message resets only a subset of controllers. This is for GM/GS but Bassmidi in GM/GS mode uses the same values for these controllers. If you need more detailed answers you should as Ian at www.un4seen.com

I do not think Claudio here can give you more detailed answers.

Tnank you, Falcosoft!

I assume that setting to GM or GS or XG always reset controllers the same way.

Overall I see that BASSMIDI behaviour conforms to Roland MIDI specs. Is there a particular reason for CC#6 (Data entry MSB) is reset to 2?

One difference between GM/GS and XG/GM2 resets is that Bank MSB (CC# 0) on channel 10/drum channel is set to 127/120 respectively by XG/GM2 resets. In case of both GM and GS Bank MSB is set to 0 on all channels.

This corresponds the default Pitch Bend Range/ RPN(0,0) value of 2 semitones that is set by all known resets in Bassmidi.

Re: GM/GS/XG system exclusive messages and controllers default values

Now that is clear about NRPN, controllers and their default values it would be nice to know which system exclusive messages are understood by BASSMIDI and so by VMS.
I see that there are a lot of sysex messages out there and each device manufacturer has defined his own. I see also that a few Roland sysex msgs are also well understood by VMS.
Can you please tell me which ones are supported by BASSMIDI/VMS?
Thank you.

As I have already said you should ask Ian at www.un4seen.com.
