Talk:Roland MT-32

message: "in the original MT-32 by dropping bit 14 (the highest monotonic bit) and shifting the remaining bits to the left, reducing the effective resolution to 15 bits"
Trying to translate this article and I'm wondering what exactly "the highest monotonic bit" means. 
Also, how does that double the volume? If a 16-bit sound signal's sound floor is -96dB, you'd exceed digital maximum in 10 bits if each bit doubles the sound. Davhorn 14:42, 4 June 2006 (UTC)
replies: text: The "highest monotonic bit" is the the highest non-sign-carrying bit. Bit 15 carries the sign; bits 14 to 0 carry the absolute amplitude. Shifting by one bit to the left (while keeping the sign bit) is the same as multiplying by two. We're talking about linear amplitude values here, not logarithmic decibel values. - NewRisingSun 19:46, 4 June 2006 (UTC)

thread_title: Monotonic bit?

message: Fair use#Common misunderstandings suggests that Roland failed to properly claim copyright over the MT-32's sound samples.  Does this mean they are considered to be in the public domain?  The Emulation section of this article seems to be referring to this in the short mention of Munt's legal "squabble", but fails to report on what the resolution was.

The MT-32 had various key combinations that could be pressed before powering up the unit. To run one of these functions, simply hold down the buttons needed and turn on the MT-32.

*Part 3, Volume and Master Volume = Runs the MT-32's test mode.
** No need to press Master Volume. Just 3 and Volume are enough to enter test mode.  —Preceding unsigned comment added by 141.70.69.139 (talk) 20:15, 21 March 2009 (UTC)

message: Someone has marked devices with entries related to the MT-32(ex. the CM line) as non-notable/subject to deletion. However, the information is still useful. Perhaps these entries should be folded into the MT-32 page? 76.102.131.84 00:26, 28 August 2007 (UTC)
replies: text: They should be deleted. There's no information on them that isn't either dispensable or already explained on the MT-32 and SC-55 pages. - NewRisingSun 13:09, 28 August 2007 (UTC)

message: An audio rendering of Sierra On-Line's Space Quest 3 Introduction music  produced using the MT-32 is available from another article. Should this media be reused for this article under the Music for PC games heading in a sound sample box? TamaMan (talk) 08:59, 24 September 2008 (UTC)
thread_title:  Sound sample box under Music for PC games 

message: I think this needs to be qualified/clarified.  It was a 'de-facto standard' only on the content-production (music composition) side of the PC-gaming industry.
In the (consumer) PC home/gaming market, the Creative Labs Soundblaster was the "de-facto standard" music card (well, actually the older "Adlib" card, which the Soundblaster fully emulated), in terms of units sold and percentage marketshare amount multimedia-equipped MSDOS PCs.  When I played some MP3-recordings of game MIDI-music (rendered on the Sound Canvas or LAPC1), I'm amazed how much better lots of old DOS games could have sounded.  —Preceding unsigned comment added by 99.50.57.185 (talk) 05:33, 10 June 2009 (UTC)
replies: text: It was the de-facto standard in that most major game studios at the time composed music for the MT-32 et al, and the music was then converted for playback on other devices. As such, the standard for MIDI playback was an MT-32 compatible synth. Everything else (OPL-based synth) was merely a pale imitation. You can liken it to the modern "de-facto standard" for audio acceleration being OpenAL (as poor as it may be), despite the fact that non-OpenAL compliant on-board audio chipsets dominate the market. 66.167.51.156 (talk) 07:41, 22 June 2009 (UTC)
thread_title:  'de-facto standard' in pc gaming music?  

message: In the article it says. "Also, some games were written to use instruments not found in the MT-32 models, and require a compatible module, such as a CM-32L, for proper sound playback"
Does that mean the CM-32L has different voices or more voices? I think a clerifcation would help the article. --95.88.250.251 (talk) 07:57, 30 June 2010 (UTC)

message: Some of the onboard sound cards circa 1997 were qualified by DOS games of 1988-1994 as:
* Sound = SoundBlaster
* Music = Roland MT-32.

replies: text: Both the MT-32's LA32 synthesizer and reverb chip compute sound data using integer instead of floating-point arithmetic, thus losing precision during every division operation, which manifests itself as quite audible quantization noise in the digital output.
It provides no references, and in the late-80s few if any other digital synths would have been using FP at the time, so this is not at all unique to the MT-32. Thus I find this passage vague and provides no useful information. Deleting in favor of better information I'm adding. 64.83.196.13 (talk) 21:06, 2 September 2011 (UTC)

message: There, added some info about the RWI mods. Might want to follow up with User:Robin Whittle for some info past 1990, like if he ever reworked the mods for the newer revisions/derivatives, and maybe an estimate of how many RWI MT-32 mods were performed. Back in the day, my dad had his MT-32 modded by LA Custom Instruments. 64.83.196.13 (talk) 20:42, 3 September 2011 (UTC)
