This is a help page listing which MIDI messages can be used for common things across General MIDI, Roland GS and Yamaha XG.
General notes:
- GS doesn't seem to have a publicly available formal standard, so the Roland SC-55mkII manual is used as a reference. Later Roland devices seem to use the SC-55mkII as the baseline for GS.
- Microsoft GS Wavetable Synth only supports a tiny fraction of the GS features, despite the name.
- XGLite only supports a subset of the XG features.
Symbol legend:
- ❌ — Not supported (according to the standard; the device might still have it as an extension)
- 👻 — Undocumented, but appears to work on some devices in testing
- ⚠️ — Supported, but not useful
- *️⃣ — Supported, but meaning is standard-specific or depends on other factors
- ✅ — Supported
- [88] — Supported only by Roland SC-88 and later (not part of basic GS/SC-55)
Control Change messages

|
Notes |
|---|---|---|---|---|---|
| 0 | Bank Select MSB | ❌ | *️⃣[1] | *️⃣[2] | On GS, this selects variation instruments. On XG, this selects banks. Common numbers: |
| 1 | Modulation | ✅[3] | ✅[1] | ✅[4] | On GS and XG, this is Vibrato by default[1][4] |
| 5 | Portamento time | ❌ | ✅[1] | ✅[5] | Value 0 is shortest/fastest.[1][5] On XG, it is cent-linear.[5] |
| 6 | Data entry MSB | *️⃣ | *️⃣[1] | *️⃣[5] | (Used for RPNs and NRPNs) |
| 7 | Volume | ✅[3] | ✅[1] | ✅[5] | |
| 10 | Pan | ✅[3] | ✅[1] | ✅[5] | |
| 11 | Expression | ✅[3] | ✅[1] | ✅[5] | On GS, this is multiplied with Volume to control overall volume.[1] |
| 32 | Bank Select LSB | ❌ | ❌[1] | ✅[2] | On GS/the SC-55, this does nothing. But the SC-88 onwards use this to select maps:
On XG, this selects extension instruments.[2] |
| 38 | Data entry LSB | *️⃣ | *️⃣[1] | *️⃣[5] | (Used for RPNs and NRPNs) |
| 64 | Sustain or Hold1[6] |
✅[3] | ✅[6] | ✅[7] | 0–63 = Off, 64–127 = On.[6][7] |
| 65 | Portamento | ❌ | ✅[6] | ✅[7] | 0–63 = Off, 64–127 = On.[6][7] |
| 66 | Sostenuto | ❌ | ✅[6] | ✅[7] | 0–63 = Off, 64–127 = On.[6][7] |
| 67 | Soft or Soft Pedal[8] |
❌ | ✅[6] | ✅[8] | |
| 71 | Sound Controller 2 or Harmonic Content |
❌ | 👻[9] | ✅[8] | On XG, relative adjustment of filter resonance (64 is zero change).[8] On GS, there is no documented support for it, but there is an NRPN. SC modules from at least the SC-88VL onwards appear to respond to it anyway and behave like XG.[9] |
| 72 | Sound Controller 3 or Release Time |
❌ | 👻[9] | ✅[8] | On XG, relative adjustment of envelope release time (64 is zero change).[8] On GS, there is no documented support for it, but there is an NRPN. SC modules from at least the SC-88VL onwards appear to respond to it anyway and behave like XG.[9] |
| 73 | Sound Controller 4 or Attack Time |
❌ | 👻[9] | ✅[8] | On XG, relative adjustment of envelope attack time (64 is zero change).[8] On GS, there is no documented support for it, but there is an NRPN. SC modules from at least the SC-88VL onwards appear to respond to it anyway and behave like XG.[9] |
| 74 | Sound Controller 5 or Brightness |
❌ | 👻[9] | ✅[10] | On XG, relative adjustment of filter cutoff (64 is zero change).[10] On GS, there is no documented support for it, but there is an NRPN. SC modules from at least the SC-88VL onwards appear to respond to it anyway and behave like XG.[9] |
| 84 | Portamento Control | ❌ | ✅[6] | ✅[10] | Value is MIDI note number.[6] On XG, ignores Portamento Time (always 0).[10] |
| 91 | Effect 1 depth or Reverb send[6] |
❌ | ✅[6] | ✅[10] | On GS and XG: Reverb send level[10][6] |
| 93 | Effect 3 depth or Chorus send[6] |
❌ | ✅[6] | ✅[10] | On GS and XG: Chorus send level[10][6] |
| 94 | Effect 4 depth or Variation send or Delay send[11] |
❌ | [88][11] | ✅[10] | On XG: Variation send level.[10] XGLite does not require variation effects to be supported.[12] Not supported on GS/SC-55, but SC-88 and onwards use this for Delay Send Level.[11] |
| 96 | Data increment | ❌ | ❌ | *️⃣[13] | (Used for RPNs and NRPNs) (TODO: check this) |
| 97 | Data decrement | ❌ | ❌ | *️⃣[13] | (Used for RPNs and NRPNs) (TODO: check this) |
| 98 | NRPN LSB | ❌ | *️⃣[6] | *️⃣[13] | (Used for NRPNs) |
| 99 | NRPN MSB | ❌ | *️⃣[6] | *️⃣[13] | (Used for NRPNs) |
| 100 | RPN LSB | *️⃣ | *️⃣[14] | *️⃣[15] | (Used for RPNs) |
| 101 | RPN MSB | *️⃣ | *️⃣[14] | *️⃣[15] | (Used for RPNs) |

|
Notes |
| 120 | All Sound Off | ❌ | ✅[14] | ✅[16] | Standard but optional MIDI feature, not required by GM. Cuts off currently played sounds on the channel as soon as possible,[17] skipping the "release" part of sounds, unlike All Notes Off.[16] |
| 121 | Reset All Controllers | ✅[3] | ✅[14] | ✅[16] | (TODO: How does this affect RPNs and NRPNs?) |
| 123 | All Notes Off | ✅[3] | ✅[14] | ✅[16] | Standard but optional MIDI feature,[18] required by GM. |
| 124 | Omni Off | ❌ | ⚠️[14] | ⚠️[19] | Standard but optional MIDI feature,[20] not required by GM. "Omni" means each part responds to all channels,[20] which is not appropriate for a GM synth, so changing to/from Omni mode is not possible. The message is treated only as an All Notes Off.[14][19] |
| 125 | Omni On | ❌ | ⚠️[21] | ⚠️[19] | |
| 126 | Mono On (Poly Off) | ❌ | ✅[21] | ✅[19] | Standard but optional MIDI feature,[20] not required by GM. On GS and XG, this message sets the part to monophonic mode and performs an All Sound Off.[21][19] GS and XG ignore the value in the message,[21][19] but note that it has a meaning in the MIDI specification! |
| 127 | Mono Off (Poly On) | ❌ | ✅[21] | ✅[19] | Standard but optional MIDI feature,[20] not required by GM. On GS and XG, this message sets the part to polyphonic mode and performs an All Sound Off.[21][19] GS and XG ignore the value in the message,[21][19] but note that it has a meaning in the MIDI specification! |
RPN messages
| RPN MSB |
RPN LSB |
(combined) | RPN name |
|
|
|
|---|---|---|---|---|---|---|
| 0 | 0 | Pitch Bend Sensitivity | ✅[3] | ✅[14] | ✅[16] | |
| 0 | 1 | Fine Tuning | ✅[3] | ✅[14] | ✅[16] | |
| 0 | 2 | Coarse Tuning | ✅[3] | ✅[14] | ✅[16] |
For software that needs a single number for an RPN rather than a separate MSB and LSB, you can just use the LSB.

System Exclusive messages
System Exclusive (SysEx) messages are required for advanced features like changing effect types, configuring controllers/LFOs, etc. There are a huge number of them and they are completely incompatible between standards, so they are out of scope for this article. The following are only a few essential ones:
| SysEx (hex) | Name |
|
|
|
Notes |
|---|---|---|---|---|---|
| F0 7E 7F 09 01 F7 | General MIDI Level 1 System On | ✅ | ✅ | ✅ | Sets module to GM1 mode and resets settings for all parts. Broadcast message addressed to all devices. Note: some early GS devices (early SC-55 models) don't support GM and won't respond to this. |
| F0 41 10 42 12 40 00 7F 00 41 F7 | GS Reset | ❌ | ✅ | ❌ | Sets module to GS mode and resets settings for all parts. Addressed to device 17 (default device number). |
| F0 43 10 4C 00 00 7E 00 F7 | XG System On | ❌ | ❌ | ✅ | Sets module to XG mode and resets settings for all parts. Addressed to device 1 (default device number). |
| F0 41 10 42 12 40 1A 15 02 0F F7 | GS: Patch parameters, Part 11 § USE FOR RHYTHM PART → MAP2 | ❌ | ✅ | ❌ | Sets part 11 (mapped to channel 11) to drums mode, using the 2nd set of drum parameters. Addressed to device 17 (default device number). For XG, you can use a Bank Select MSB instead (see above). |
