1992 - 16 bits, finally also from Creative Labs, SCC-1
Sound Blaster 16
SB 16 ASP - thx to Jörg Weske
Creative Labs brought their first 16 bits sound card, the SB 16, substantially later to the market than their competition. Equipped with a 16 bits DSP, an OPL3 for FM music playback, as well as in extended versions with an ASP ("Advanced Signal Processor" - for compression, speech synthesis and QSound spatialization), and an interface for expansion boards, this card should sweep all other competitors from the market.
Full CD quality with 16 bits and 44.1 Khz was finally also possible with a Creative Labs card. They had also put effort to clean up the interface chaos of its predecessors. Unfortunately, they've done their job very thoroughly.
Generally, the consumer thinks that if a product carries the same brand, backwards compatibility is given. And by looking on the product packet, you also see there's a "Sound Blaster compatible" written on it. Therefore everything should be ok, shouldn't it? Yes, because the imprint didn't lie... the card is actually SB-compatible - nonetheless, however, not SB Pro compatible! Admittedly the card plays along without complaints if you use it as SB Pro compatible, and returns also everything with the correct frequency. However, there was a little point, that they forgot in the pre-delivery inspection - the card could not play stereo while being in SB Pro mode! This manifested itself in a very twisted (mono) playback of stereo samples, since samples are being sent interleaved to the card, alterning left and right.
Creative will officially probably never call this a bug. It is however already peculiar funny if the card processes the rest of the SB Pro commands, and only fails at this point....
They seemingly also cheated in some other aspects. Namely, the ADC (Analogue Digital Converter) could only dissolve only bits! Many users could prove this in their attempts, however this has never been officially confirmed. That is even more tragic, as exactly these 12 bits were seen as the disadvantage of the AdLib Gold compared to this card.
Sometimes, marketing is simply everything.
Nevertheless, this card found many buyers. After all old games could often work easily with the card, and upcoming games adapted this card very fast, thanks to Creative's support. So, also this card placed a quasi standard again, that could not be broken by anybody else. The integrated ASP of the more expensive models however was practically never used. Probably also, because they - contrary to the usual practice - never disclosed any direct programming guides. Developers should use the delivered drivers, which most users probably just uninstalled since it was taking up the precious lower 640KByte RAM.
Creative Labs Wave Blaster I
This card introduced the possibility of using an add-on card, for example to extend it by a wave table. Finally newer games could be played with something better than the pathetic FM playback. While they didn't land a hit with their own "Wave Blaster I", many other companies, for example Roland and Yamaha, offered such boards as well, and could easily pass the WB I.
It shouldn't take too long that competition offered this extension interface on their cards, too...
If you are going to purchase a used card for compatibility with old games, you may be overwhelmed by the number of SB 16 versions. You can skip the ASP chip, which is practically not used. If you want to use a MIDI add on board, skip any Value version (which doesn't have it) and watch for a DSP version of 4.05, if possible. These should can be identified by having jumpers for their IRQ selection (the later versions used software based configuration). Higher DSP versions have a hanging note bug, which occurs when you use MIDI and sampled audio at the same time (as it is the case with most games).
Avoid any cards with a Vibra chipset! These cards lack some features, like bass/treble settings and the expansion header. More importantly, however, some later Vibra cards skip the OPL3 chip for an inferior solution using "CQM synthesis", which will make any AdLib based games likely sound pertty thin and not like the original. You can identify these cards by their much smaller size, by less chips, and mostly one of its chips has "Vibra" standing on it.
Another pure MIDI card of the house Roland was developed, this time based on the external Sound Canvas module SC-55. Also this one was primarily targeted at professional musicians, and represented the first PC card with Roland's expansion of the General MIDI standard, General Synthesizer (GS).
The card has got 24 channels, that were fed with 16 bits PCM samples from the 4 MB sized sample ROM, and were mixed with 44.1 Khz resolution. Also here is valid, as with the LAPC-I, that 24 channels doesn't mean 24 different instruments playing simultaneously. However it's not as extreme as with the LAPC-I, 16 Instruments could be played, 16 times multitimbral here. The ROM content was compressed and included 317 sounds in the first, 354 sounds in the second version of the card.
There was an MPU401 compatible interface on board as well, consequently it was supported by almost each program that played music - the card was plugged in and it worked. No drivers, no unnecessary hurdles.
Additionally, the card adds chorus capability over the LAPC-I, that only supported reverb/delay. The card could also be brought into MT-32 compatible mode, but no samples could be uploaded! Games doing this - and their amount was not that small - didn't sound like on the original LAPC-I.
However you shouldn't look at the card in the way of mediocre LAPC-I support, because it presumably represents until today the highest of the feelings when dealing with MIDI playback! Game music composers at the time preferred Roland products which this card was derived from, hence using this card often lets newer games sound as they're supposed to. I shouldn't talk about it, you have to hear it - try the samples!
As always, you buy good with Roland, but definitely not cheap. The card was prized at about $500 - approximately the same as the LAPC-I, which temporary sold in parallel.
Trough this it is, as the LAPC-I, a rarity, and only hard vs. expensive to get in hands.
The RAP-10 should be mentioned as well, which approximately hit the market one year later. This was the first consumer card by Roland, which also mastered sampling on CD niveau. The MIDI part was with 128 instruments (based on the SC-7 module) in opposite to the SCC a bit shortened, but otherwise identical. Though this card was intended only for Windows use, it was supported by quite a bunch of games, either directly as RAP-10, but also indirectly (MPU401/SCC-1).
