Re: Type 1 Hanging Note bug
Posted on 2022-04-22, 16:53
does this mean that the bug ONLY affects the aforementioned games? Or that it can affect all games but it's most obvious in those listed? On affected cards, and where the MPU has been initialized, the last (latched) MIDI byte is re-sent with each and every DMA interrupt that occurs during digital …
Re: Is a Roland SC-55 Okay or do I need a MT-32 ?
Posted on 2022-04-21, 05:52
What I mean really are games that *only* support MT-32 and not GM ... I am fairly certain it is not in the hundreds. Here's a summary of "Western" PC titles that I put together several years ago, based on a larger and mostly-validated set of data from the MobyGames database, and specific to …
Re: Fixing the Roland CM-500 Vibrato Bug
Posted on 2022-02-10, 03:43
Out of curiosity, could a fix like this be made for the SC-55 and SC-155 units with the 2.00 firmware which have that bug with the missing drums ? In theory. I don't believe the SC-55 firmware has yet been disassembled to the necessary degree though. That particular behavior is almost a non-issue …
Fixing the Roland CM-500 Vibrato Bug
Posted on 2022-02-09, 16:47
In 2005, MT-32 music enthusiasts made known a discrepancy in the LFO rate of Roland's third-generation Linear Arithmetic synthesis implementation affecting both the CM-500 and CM-32LN modules, as well as the LAPC-N C-Bus boards. This errant behavior noticeably manifests as a faster vibrato rate than …

Posted on 2022-02-05, 17:56
Would you explain how this works with your setup, please? With the MTP, it's just a matter of routing a given input port to any combination of output ports, and then muting MIDI channels on the output ports as appropriate. E.g., input 1 routes to outputs 1 and 2, with the even MIDI channels muted …

So you should try a game that is known to use only the default instruments: I realize the list isn't of your making, but the owner really ought to remove Legend of Kyrandia, which sends an entire bank of 64 custom timbres. Most of these are indeed related to sound-effects, but that usage is pretty …

I prefer Yamaha's MU devices for this kind of setup, as they provide some additional functionality beyond most …
