Re: About Roland Virtual Sound Canvas 3

In this post I want to make list of All VSC Sound Banks that are available and can be used in Format analysis effort: VSC 1.00 Trial ("VSC55T.EXE") : SC-55 Sound bank "vsc.dat", size: 1,452,448 bytes VSC 1.00 to 1.20 Update ("v5up120e.exe"): no new Sound bank is included with the update VSC 1.20 …

@Stretch thank you, at the moment, the 2nd post is useful to me, because it shows where in the VST DLL v1.60 the Sound Bank data are embedded. I think to prepare post, were I collect information for all VSC Sound Banks available and especially those that allow direct comparison between their …

@Falcosoft , thanks for the info. I guess is some compatible with "CM-32/64 sound bank" definition, but as you said nothing close to the real device or what Munt is capable to do. I guess same is with TR-808/909 text I found in the VSC Sound Bank - interesting, now Roland has VST that is TR-808 …

I figured out few bytes from the Sound Bank Header: * there is text string "0.97" (VSC 1.x), "1.01" (VSC 2.x), etc, which obviously is the Version of the Sound Bank * also the Sound Bank Size is very obvious, for example there is "A0 29 16 00", which written as 001629A0 in hex is 1452448 decimal …

BTW, the VSC decrypted Sound Banks contain information about "CM-64/32L", possible copy of its ROM (maybe Roland included their own "MUNT" in the VSC soft-synth, who knows?!) - to show the encrypted section and the one decrypted with "vscdec.c" i am attaching the corresponding screenshots.

I was wondering how you'd concluded it was decrypted, being that you don't know the format of the data? by getting readable ASCII strings in the data. [EDIT] add screnshots to make it more clear - how Encrypted and Decrypted data block looks like. it's the same with VSC Sound Banks - I am not sure …

I am releasing my decryption code - it's attached to this post. Contrary to the old 'sm0n' release: https://www.vogons.org/viewtopic.php?t=13865 it doesn't use hard-coded decryption key, but rather it is able to find the key. That allows it to work not only with VSC 3.x as the old 'sm0n' release, …

Big news (at least to me, maybe it was done in the past, but I am not aware of it - if you know, let me know, to prevent me reinventing the wheel): So, I was able to decrypt small portion of the Sound bank from ROM dump from real SC-55 hardware device! Yes, only "small portion" for the moment, …

for completeness, i've just found this link in the web-archives: https://web.archive.org/web/20050205022507/http://www.edirol.com/products/info/archive/vsc88h3.html indeed VSC 3.x was released for MacOS too. So, that's consistent with what 'Jo22' poster earlier in this forum thread: https://www. …

Guys, I've already moved several steps further from what 'sm0n' did, all those years ago, here : https://www.vogons.org/viewtopic.php?t=13865 We're very lucky that in VSC 3.x Roland messed up the Sound Bank encryption big time (thank you, whoever Roland employee did that! BTW, when such thing …

mattw, there is code posted in vogons.org which decodes the bank format here: Virtual Canvas Sound Banks @Stretch, big thank you! And even Bigger thank you to the person made that post with full details for the encryption algorithm almost 15 years ago!! Wow, it's amazing that the Sound banks from …

Roland Virtual Sound Canvas 3.x I fully covered in the first 3 posts, as well as subsequent and last from the series Roland Virtual Sound Canvas MP1 (Multi-pack V1), which is VSC 3.23 + VST version of the soft-synth. So, I have nothing to add. Now, we can only hope someone will reverse-engineer the …

Roland Virtual Sound Canvas VSC-88 (Official name) Roland Virtual Sound Canvas 2.x (Unofficial name) Year of Release: 1997 (I must say very impressive, because according to Roland Help files, it emulates Roland SC-88VL, which means that less than 1 years after they released the SC-88VL hardware, …

OK, in the next several posts, I will post version by version all the information I collect, starting here with: Roland Virtual Sound Canvas VSC-55 (Official name) Roland Virtual Sound Canvas 1.x (Unofficial name) Year of Release: 1996 Features (from the Roland Help File): Number of parts: 16 …

I didn't expect this - it took me no time to find Demo/Trial version of VSC-88 v2.1a using Google, the file is called: "TVSC8821.EXE" and even more surprising Roland released version of it for Macintosh as well: "vsc88-21-trial.sit". However, it seems "TVSC8821.EXE" is Win9X only, i.e. v2.x contrary …

OK, I dig up Release/Update History mainly from the old Edirol brand website of Roland, it's interesting so to sum it up here: * first release was VSC-55, i.e. Virtual version of SC-55 * then there was VSC-88 2.1a, i.e. the second release was Virtual version of SC-88: I guess it was supporting SC-55 …

Actually, the VST from Roland VSC-MP1 is even more interesting in terms of reverse-engineering potential, because it has 3 files: * RVI01.dat : identical to 'vsc88pro.dat' from "Edirol (Roland) Virtual Sound Canvas 3.x", i.e. that's the sound bank. Also, that means the VST defaults to SC-88Pro mode. …

Hi All, something like 15 years before Roland released "Sound Canvas VA": https://www.vogons.org/viewtopic.php?f=62&t=46111 they did release "Edirol (Roland) Virtual Sound Canvas 3.x" : https://web.archive.org/web/20120302180655/http://www.roland.com/products/en/VSC-88H3/ I cannot find any …
