If they are SC-88 Pro files: I had this too. I think some effects in those MIDI files (NRPN/Sysex) causes it. It's with SC-88 Pro files only as far as I'm aware.

I'm glad it's not just me! Were you able to find a midi file that causes this? because it definitely smells like a bug.

It's not a bug; it just happens to be the X16GS responds to SC88 Pro insertion effects commands in a different way.

The board claims it's fully GS compatible. Does SC88 Pro have a different spec? If so, what is it?

GS compatible = SC55 native. Native modes for later modules such as 88, 88 Pro, 8850, etc are a different thing.

I Have not purchased the x16gs yet.

I couldn’t find information about requirements for the software. Will it run on windows 98/98SE?

Can I “permanently” connect the USB the PC while it’s installed on a soundcard in the PC?

Are there any power/ground issues if you room that USB and hooked it to another computer (#2) while it’s installed/running in computer #1?

I just don’t wanna blow anything up unintentionally. I don’t see any written warnings; at the same time, I don’t see anything telling you that it’s ok.

Thanks!

Hello,

I've bought a DreamBlaster X16GS from Serdashop. It's very good quality MIDI module, but I don't understand how the Insert Effects are working.

The manual said it has to be turned on by NRPN Controls:

NRPN # Description default
39xxh Set Insert FX mode ON/OFF for MIDI channel xxh
xxh=0 to 0Fh if port 1, 10h to 1Fh if port 2, 20h to 2Fh if port 3, 30h to 3Fh if port 4
value 0 = normal track mode, 1 = connected to IMFX1, 2 = to IMFX2, 3 = to IMFX3

Ok, I'll send the CC#99 57, CC#98 0 (MIDI port 1 ch. 1) and CC#6 1 (IMFX1) and after that the MIDI port 1 ch. 1 is muted.

Next in the maual:

Insert Effect NRPN Controls
Stereo Insert MFX1 is controlled by NRPN controls send on MIDI channel1, MFX2 by MIDI channel 2, MFX3 by MIDI
channel 3.

I don't understand this exactly... Someone please help me what does it mean?

Configuration
NRPN Description
0x0C00 Effects Configuration:
• 0 = Off
• 1 = Dyn -> EQ -> Mod/Wah -> Tremolo/Delay
• 2 = Dyn -> EQ -> Mod/Tremolo /Wah -> Delay
• 3 = EQ -> Dyn -> Mod/Wah -> Tremolo/Delay
• 4 = EQ -> Dyn -> Mod/Tremolo /Wah -> Delay

Ok, I'll send the CC#99 12, CC#98 0, CC#6 1 NRPNs, but the port 1 channel 1 is still muted.

What am I doing wrong? How to make the IMFX audible?
