I want to add my 2 cents on

option available in some forks.

In my testing the treble output gets slightly elevated with this option called vs. without it. I confirmed this with a spectrogram. There may be a technical explanation related to how SDL handles sample rate mixing. I don't know the specifics. Based on the spectrogram it could be that residual frequency content stays contained in ultrasonic frequencies, thus inaudible, whereas without oversampling the residual content gets combined in the audible frequency ranges instead.

What matters most to me is that I prefer the warmer tonal quality when

Very interesting, i need to try this option.

Kinda offtopic question: what font did SC-55 use on its front panel?

Roland's SCVA uses ODRF_UPR-Regular.otf, if that is of any use?

https://github.com/jcmoyer/Nuked-SC55/releases/tag/0.6.1

Added hashes for mk2 roms with a CTF patch applied from shingo45endo/sc55mk2-ctf-patcher. (#51)

hey uh popping by here to ask a question about the license. do audio recordings of the program count as derivative works? i want to upload an UNMONETIZED song that i made with the program to youtube, but i'm worried that i might be violating the license by uploading it to a site that runs ads on all videos (regardless of monetization)

also sorry for double post, but i've been unable to contact nuke over discord about this for the past 363 days

I'm pretty sure the Doom + Doom II and Heretic + Hexen remasters used Nuked to record the SC-55 versions of the soundtrack, so I don't think it should be a problem.

I'm pretty sure the Doom + Doom II and Heretic + Hexen remasters used Nuked to record the SC-55 versions of the soundtrack, so I don't think it should be a problem.

The problem is that
Heretic was recorded in Soundblaster AWE32 hence the higher range since SC-55 is missing a ton of tones and some music mainly The Crypts sounds off when in AWE32 is perfect, and Hexen obviously used a SC-88/SC-88PRO for the redbook audio and ingame music.
Which Nightdive fumbled it and Edward went on to show a AWE32 without OPL claiming that the card and the soundtrack was OPL, and say that the game was recorded in SC55.

I hope that one day we get a Nuked-SC88 so Hexen, shadow warrior and such can be finally heard as it was intended.

I'm reasonably sure you are allowed to upload recordings of midi files played back with nuked. You are of course allowed to upload music you compose. You probably do have to own your own sound canvas or sound canvas VA, though.

If youtube runs ads on the video, it's because someone legally monetized it. If it's a song you made with roland samples, then it would probably have to be Roland themselves that monetized it. If they monetize it and don't have it taken down that's giving permission.

They don't randomly put ads on videos that can't actually be monetized. There will probably be no ads on it.

Can someone please add some clarification surrounding the RLP-3237?

Currently, on github.com/nukeykt/Nuked-SC55 the ROM set is listed as follows...

1RLP-3237:
2R15199827 (H8/532 mcu) -> rlp3237_rom1.bin
3R15209486 (H8/532 extra code) -> rlp3237_rom2.bin
4R15279824 (WAVE 16M) -> rlp3237_waverom1.bin

I did some research and it seems that RLP-3237 is the part number for the VE-GS1. But when you look on Google it seems all of them use part number R15239229 for the WAVEROM, instead of the listed R15279824. See the example below...

Said example uses the exact same rom1 and rom2 chips. It's just the WAVEROM that's different.

Any idea as to which is the real 16M WAVEROM?

I'm including the works by mattw, to try to answer this question.

Thanks, @Karmeck

Would you be fine sending me a DM? I've also got a similar list I'd like to send you.

I'm more of a forum dweller, so I can't seem to send DMs myself.

There's still no sign of Roland releasing updated replacements to their Virtual Sound Canvas offerings, so I think this is safe for the time being. They have just released a massive VST offering of their late 90's and early 2000's pro-grade synths (non-SC/GS) and seem to be fully focused on music composition offerings, rather than music enjoyment.

Update from https://github.com/linoshkmalayil/Nuked-SC55-GUI-Float

Update 0.6.2 Latest
- Added loading ROMS using ROM Hash
- Added command line option to control gain
- Added ASIO channel routing support
- Fixed crashing when using no LCD mode
- Basic support for EMIDI looping points

Coming late to the party, but I'm only just now discovering Nuked SC-55 and its emulation. As a user of an SCC-1 in the 90's, and in more recent decades, an SC-55mkII owner, I wanted to share some opinions.

First off, it's quite remarkable! It sounds just like the real thing, virtually indistinguishable. Though when I compare it side by side with my real hardware Roland SC-55mkII, something seems slightly off. The real SC-55mkII definitely sounds louder, but also the instruments are just a bit brighter and the reverb/echo fuller. I was listening to the chimes for example in one MIDI piece, and they just seem sharper and more defined. To get a more level playing field, I hooked a different pair of speakers directly into my Roland, and then the computer playing Nuked. Same thing. Even adjusting the volume levels down on my Roland to compensate.

Is it my imagination, or is there an actual subtle difference? I should probably try some headphones to compare, but wondering if anyone else has noticed a difference or it's just me...

On a side note, I'd love to try tinkering with Nuked live using my MIDI keyboard that's connected to my old Audigy sound card's joystick port (with a DIN-5 break out adapter). Particularly the JV-880 or the SC-88 and others which I don't own. Is there a recommended way to do it with Windows 7? I've installed LoopMIDI and tried using MIDI-OX to remap the MPU-401/MIDI output to the virtual LoopMIDI, but nothing is happening. Probably overlooking something obvious.

Hi,
1. Nuked SC-55 does not emulate the analogue circuits/amplifier parts, only the digital parts of the box.
2. There is a command line option to define what Midi In port should be used by Nuked SC-55. (AFAIR it's -px where x is the port number). You should not use LoopMidi for this, you simply have to set your Audigy's Midi In port as the active one used by Nuked SC-55.

Ah, that would explain the subtle, but audible, difference. It's certainly not a day/night difference, most people wouldn't notice unless you compared them side by side.

Good tip! Not only did I need to disable LoopMIDI, but I inadvertently was trying to go through the OUTPUT MIDI port, while plugging into the front MIDI INPUT on my SC-55mkII. I had forgotten I didn't have dual DIN cables connected. Plugging directly into the MIDI input on my PC end, all is now well!

I am noticed some delay lag between playing notes on the keyboard, and Nuke-SC55 responding. It makes playing difficult, if not impossible. Would a faster machine eliminate the lag? Another question, I'm trying to get my MIDI keyboard to communicate with the Roland JV-880 in emulation, but not having much luck. I likely need to figure out what virtual button presses are required to have it receive MIDI data to have a listen to the different patches it offers.

Latency is defined by the audio buffers/buffer sizes. If you do not experience garbled sound with your current audio buffer settings then a faster machine will not help. You should try to decrease the amount and size of the audio buffers until you get garbled sound. But to tell you the truth Nuked SC-55 is not really optimized for real-time jamming.
(Use the -ab command line switch. But first you should start Nuked SC-55 with the -help command line switch to get more info about the syntax.)

For real-time jamming through Midi Input less than 10 ms audio latency is required but with the SDL audio backend that indirectly uses shared WASAPI audio output mode on Windows this is not realistic.
There is a newer fork of Nuked SC-55 that introduced ASIO audio backend but AFAIR you have to compile it for yourself with ASIO output mode enabled to get it:
