Hello,
I've found quite an interesting "bug" if you will. I am not entirely sure if
its with MIDIMapper or some sort of hardware limitation.
I use MIDIMapper on two computer that previously had very close
specifications where the CPU, memory, motherboard, windows version, sound
card, and USB MIDI device were all the same as follows: i7 12700K, 64GB of
DDR4, Asrock Z690 Extreme(BIOS v1.17) , Windows 10 Pro 21H1, Sound Blaster
Audigy Rx, Roland UM-ONE Mk2. The GPU and Storage was different on both PCs
but I dont think that is relevant here. On both these computers I had them
setup to use effectively one of 5 MIDI devices that I could select at will
with MIDIMapper;
- Microsoft GS Wavetable Synth
- SB Audigy 5/Rx Synth A [4FC0]
- SB Audigy 5/Rx Synth B [4FC0]
- OmniMIDI
- 2 UM-ONE
Both computers worked flawlessly with this setup for a bit over a year.
However, last week I got my hands on 13700K in exchange for one of my
12700K(someone needed it's AVX-512 support). One 1 of these PCs I updated the
BIOS from 1.17(First version for retail release) to v10.04 for 13th gen
support to use my new 13700K. Everything initially appeared to work fine but
I noticed that the SB Audigy 5/Rx Synth A/B [4FC0] options were missing from
MIDIMapper(2.0.3). At first I thought it might be an error with MIDIMapper so
I updated it to the latest 2.1.1 beta thinking this might fix it; It did not.
For the sound card drivers I am using Daniel K's Audigy support pack 8.0 on
both computers. I thought maybe the BIOS update effected the drivers somehow
so I Uninstalled the drivers and Re-installed them. This changed nothing.
Since I have 3 Sound Blaster Audigy Rx(s), 2 in these PCs and 1 spare, I
tried all 3 in the updated PC while uninstalling/reinstalling the drivers and
MIDIMapper each time I swapped one out; The SB Audigy 5/Rx Synth A/B [4FC0]
options never came back on the updated PC. Since I have a spare PCIe slot on
the Updated PC I tried the Sound Blasters in that slot with no change. I
tried using the last Audigy Support pack from Daniel K (v8.1) and that didn't
change anything. I double checked all BIOS settings on both PCs and made sure
they matched(outside the CPU settings obviously)
I verified each of the 3 Sound blasters on the outdated PC and confirmed all
3 worked with their SB Audigy 5/Rx Synth A/B [4FC0] options without needing
to reinstall the drivers or MIDIMapper. Just as a sanity check I did update
the drivers to those from the Audigy Support pack V8.1 and the SB Audigy 5/Rx
Synth A/B [4FC0] options remain in MIDIMapper on the Outdated PC.
Since I do still have one of the 12700K CPUs; I pulled it from the Outdated
PC, put it in the Updated PC, reverted the Updated PC's BIOS back to v1.17
and lo and behold; the SB Audigy 5/Rx Synth A/B [4FC0] options came back to
MIDIMapper (2.1.1 for the record). So I put the 13700K back in the system
after Re-updating the BIOS to v10.04 and the SB Audigy 5/Rx Synth A/B [4FC0]
options disappeared again!
I am not sure if this some new hardware limitation from the Z690 BIOS update
or a bug in the MIDIMapper Software, so I figured I'd share this here and see
if anyone has any ideas.
