Sure thing. Remember that each parameter has its own specific address. For Master Volume, it's 10 00 16.

So, to adjust only the Master Volume, the format would be:
F0 41 10 16 12 10 00 16 DATA CHECKSUM F7


I made a little ASCII diagram in this thread that may or may not help explain this better:

Eh, I imagine you're referring to its effects daughterboard?

I can't recommend contacting Roland Japan at all. If it's operational or parts-related help you're after though, Roland's US support group has been pretty stellar.

I imagine it might be the same issue affecting the "Space Alvin" patch, described on the earlier pages of this thread. I'll try to take a deeper look sometime this week...

It looks like the "Sound Machine" is a Chinese SB 2.0 clone that was bundled/sold by QuickShot.  There was some discussion about it in this thread on the VOGONS forum.

I can't claim to be a hardcore Sierra collector or anything, but it does look like there were at least two versions.  I imagine the version with the glittery box and MPC-label (as in my photo above) was both early and short-lived, given some of the file dates, and the references to Windows 3.0, which was succeeded by Windows 3.1 just a few months later.

Here are some additional audio sample comparisons.  I'm a bit conflicted as to which I prefer, and think some combination of the two would be ultimately preferable.  In the cases of pronounced sibilance, as with the Weeping Willow song, the filtering is welcome, but in many others (as the following examples show), the audio quality was needlessly compromised.

There's an AUDCOMPU.DRV driver for use with the CompuAdd Multimedia card on the original release, if anyone cares about such things.

Frequency spectrums tend to paint a more comprehensive picture (I'm going to be lame and not post pictures), but it looks like pretty standard low-pass, "EQ" filtration of the high-end. (In addition to the amplification your waveform diagrams show for the newer version.)

I recently found a copy of King's Quest V MPC at a thrift shop, the likes of which I've not seen before (having both the textured/glittery box and an MPC-logo-bearing requirements label).  I imagine this is the original CD-ROM release.  Compared to the version that I have as part of the 15th Anniversary Collection, the audio files are noticeably different...


MPC edition:
AUDIO001.002, 114MB, 12/12/1991

15th Anniversary edition:
AUDIO001.002, 92.6MB, 04/17/1992


While the size discrepancy seems mostly due to unexplained file duplicates, and a number of audio samples are altered besides, the biggest difference is that the audio samples themselves have gone through a filtering process between the two versions.

Here is an example from each version demonstrating the difference:

http://www.symphoniae.com/misc/KQ5CD/Audio9999_0.wav
http://www.symphoniae.com/misc/KQ5CD/Audio9999_1.wav

It doesn't seem like normal behavior, based on the manual and MIDI implementation.  Have you tried hard left/right panning, and are the rear outputs and headphone jack similarly affected?

It's nice to finally see the inside of one of these things.  I definitely wasn't expecting a different SoundEngine board. (Creative's "Wave Blaster," as you're probably aware, is an OEM version of E-MU's earlier, EMU8801 SoundEngine board.)

Other than the "Test Mode" information, everything is documented in various owner's manuals. I've not seen the "WAVE ROM" check in anything other than the Japanese E-70 manual, however...

http://media.rolandus.com/manuals/SCC-1_OM.pdf


The "Test Mode" stuff is still mostly derived at this point. I'd questioned Roland Japan about it recently, and was simply told that it's for internal use only. How nice. Notwithstanding, it is briefly mentioned in the two MIDI implementations noted below, and the specific "WORK RAM" test comes from the CM-300/500 Service Notes. Everything else I'd posted regarding the Test Mode was the result of poking around with SysEx using the CM-500, and comparing the audible results to the panel-initiated tests described in the SC-55mkII Service Notes. While I'm pretty comfortable with the Sound Test descriptions used, "EXIT TEST MODE" may not be the most accurate description of the first entry, as it's more of a reset, and perhaps more closely comparable to a "factory reset" at that.

The PC-98 version of "Steam-Heart's" is the example that Rhizome had provided in context with this issue.

Someone interested in using the MT-32 for gaming might find a guide detailing its use with newer systems/software/interfaces useful, but may not have a lot of use for hardware technicalities. From a technical standpoint, most of the relevant topics are already detailed in other publications (Wikipedia, owner's manuals, service notes).

A few of the topics seem arbitrary (Power-draw comparison? Number of PCBs?), and I'd leave out any sort of personal recommendation.



http://queststudios.com/smf/index.php/topic,1654.msg30306.html#msg30306

MIDI-OX can be used for this.

The 16-part limitation may coincide with the effect-processor's 16 separate and concurrent MFX. When compared to, say, the XV-5080, where 3 MFX are shared amongst 32 parts, the trade-off of not having to effect-juggle seems pretty well justified.

I can't imagine what technical limitation (if there even was one) might have resulted in the 128-voice polyphony. It certainly seems like a poor decision, whatever the case may be.

The "lapcn_1" photo I posted above shows "side B" of the C-Bus pinout, with the ganged +5V pair on the far left, and GND on the far right.

All three voltages are required.

I'd provided a picture in one of your threads some five years ago...

Here are the photos again though (with working links even!).

Which is, of course, the same architecture shared by the baby-D synths...
I may have overlooked something, but I couldn't see any difference in the MT-32's handling of timbre selection, as compared to the D-series synths.

Thank-you for starting this topic, by-the-way. The MT-32 doesn't seem to get much recognition for being as innovative as it was - its rhythm capabilities being another excellent example.

As Datschge pointed out, Roland's drum machines were basically either analog synthesizers or straight sample players prior to the MT-32, which leverages the LA chip to reduce the number of required PCM waveforms for a drumset through approximation (pitch-shifting, synth waveform generation, etc.).  The MT-32 drumset really was another "Roland first" in this regard, despite my presumption that it was more of a cost-cutting measure than anything else.

Take a look at the "Quijada." This instrument is a 32K waveform sample in the TR-727, but is approximated by a corresponding timbre in the MT-32 that utilizes the looping Rim Shot and Hand Clap samples.




There's a lot of shared PCM commonality between Roland's TR/CR units. Based on names/dates/sizes, it seems to me that the MT-32 shares waveforms with the TR-505/CR-1000 and TR-727, while the later D-10/110/20 synths appear to draw from both the TR-727 and the larger waveforms in the TR-626.

I'm a bit surprised you find the MT-32 drumset to be superior, frankly, and what's this about the MT-32 being more flexible? At the time, the rhythm section found in the D-10/110/20 was technically superior to contemporary Roland offerings. Is it the waveforms that you're comparing, or the timbre/tone programming (which also drastically differs)?

Yep, just a raw SID and simple joystick port - no MIDI capabilities whatsoever. While the music does have to be specifically programmed/converted for the SID, the idea was that developers would have been able to (more) easily port wares from the Commodore 64 to the PC. The premise was nice, but the Innovation board was released as the larger U.S. companies were ending C64 development, and was presumably an immediate marketplace failure.

Penya's, DemonBob's, Jolaes76's... the very same.
