Re: The Roland CM-500 GS/LA Sound Module

Congratulations on your purchase! Sounds like the market for sound modules must be in a demanding place at the moment, though. I got an SC-88 Pro for $55 on ebay last summer. No defects whatsoever, brand new and unused; only problem was that it was missing a power supply, but a quick trip to Radio …

Re: MUNT 0.1.3 w/ CM-32L support anytime soon?

There are still major problems with percussion similar to the symptoms I described in this bug report: http://sourceforge.net/tracker/index.php?func=detail&aid=1099276&group_id=123616&atid=697157 Testing the MT-32 emulator on latest ScummVM CVS with MI1 or MI2, the percussive track / part 9 is …

Re: PCjr Emulation Plays At Incorrect Pitch

Actually, no, it doesn't affect the PC Speaker emulation. I thought I would have noticed if it did, but just to double-check, I recorded the output of Monkey Island 1 intro and compared it to a clip of a hardware PC Speaker playing back the same portion of the intro.. matched completely. So this …

Re: PCjr Emulation Plays At Incorrect Pitch

No, that's not what I mean. I mean raise the pitch by 33.3% - i.e., it's outputting at 2/3 of the pitch that it ought to. To reproduce this in Cool Edit / Adobe Audition, sample the output from DOSBox, then Effects -> Time/Pitch -> Stretch. Then do Pitch Shift (Preserves Tempo) and move the slider …

Re: PCjr Emulation Plays At Incorrect Pitch

Sorry to bring this back up to the top again, but this issue still exists with DOSBox 0.6.3 and there's been no commentary on it. Try switching to machine=tandy and running any PCjr/Tandy Sounds-enabled game. Record the mixer output in your favorite recording app, then compare it to a hardware-based …

Re: Chained MT-32 "Exc. Checksum error"

The SysEx is being transmitted too fast. Just to let you know, this isn't the case. I've set the baud rate incredibly low as I mentioned before, and I've tried using MoSlo now to decrease the speed to almost unplayable levels, and I still receive the error. When it's too fast, I generally get "Exc. …

Re: Chained MT-32 "Exc. Checksum error"

No, I haven't asked the question elsewhere. Perhaps I should head over to Quest Studios and see the response. Still don't know why the data is arriving too fast, though. I've set the COM port to be as low as 150 bps with hardware flow control and no FIFO buffers, and it still produces the same …

Chained MT-32 "Exc. Checksum error"

..and now for something completely off-topic. I realize this may not be the best place to ask for help regarding an actual MT-32, given that this forum is about Munt/MT-32 emulation, but on the other hand it seems likely that a greater number of people here will own actual MT-32s or similar modules …

Re: Tandy 3 Voice?

You are correct that there are no actual PCjr/Tandy sounds add-on boards for PC ATs. This was a misconception of my own after having read several vague comments on the web about PCjr/Tandy Sound System support in games. However, irrespective of this, all of the points that have been previously made …

PCjr Emulation Plays At Incorrect Pitch

I noticed tonight while messing around with the PCjr emulation in DOSBox 0.62 [despite the lack of graphics in most games!] that playback occurs at a pitch 33.3% lower than it should be. I confirmed this by recording a sample of the PCjr emulation in Monkey Island and comparing it to a hardware PCjr …

Re: CMS Emulation Removed in DOSBox 0.62

"software wavetable" implementation wasn't in that many games... Yeah, the only major examples of games with software wavetable I can think of are some of the early 90's Epic games and Star Control 2. "Software wavetable" is such an ugly name for it, considering that it had very little in common …

Re: CMS Emulation Removed in DOSBox 0.62

In any case, having the DAC at 220h as well as CMS really doesn't do any sort of harm, because I'm totally unaware of any games that would support Sound Blaster DAC and Gameblaster simultaneously it is using DAC and adlib simultaneously on port 220 that may make conflicts (cause cms will be set to …

Re: CMS Emulation Removed in DOSBox 0.62

in real sb16 it was like this: 220-DAC 220-adlib 388-adlib in dosbox sb16 will have to look like this: 220-DAC 220-cms 388-adlib so if the game wants to use adlib on port 220 there will be conflict in dosbox Aaah, that makes it much clearer. Thank you for the detailed explanation. I was unaware …

Re: Tandy Sounds/PCjr emulation flaw

There was a game that detected tandy sound and cause of that the game tried to use tandy graphics too. This resulted in game not running. So developers just wanted to make sure no newbie will have such a problem. That makes sense, but then as you mentioned in a previous reply, there should be a …

Re: CMS Emulation Removed in DOSBox 0.62

Still, it makes more sense to treat CMS as a separate device from FM synthesis because it WAS a separate device! It actually a little more complicated than that. First there was the CMS, which was standalone, and then the SB1.0, which had the FM chips, the DAC and the CMS. Then SB1.5 and SB2.0 left …

Re: CMS Emulation Removed in DOSBox 0.62

Actually, it's oplmode=opl2 that allows use of both CMS and OPL/2 simultaneously, presumably because OPL/2 would be associated with SB1 and SB2 and therefore support CMS as well [even though SB2 really doesn't -- you'd probably find one out of the thousands that purchased it that actually bought the …
