I can not.

How about if I record from a midi synced actual gameboy?  Will my magical slicing tools work then?

Tempo wobble. Can you non automatively slice like a boss

Resurrecting this topic for a related issue:

I'm using BGB to render songs and then chopping those renders into loops for use in other software.  I'm using a high pitched pulse instrument at the beginning and end of the song to indicate where the render needs to be trimmed and I'm pretty confident that I'm doing a good job of trimming at the exact sample point where the actual song starts/stops.  This is all being done with 2-4 minute long files.

When I load the wave into BeatCleaver or the Renoise sampler to chop it up I just cannot seem to get the perfect loops I'm hoping for.  If I go by tempo detetection there's always a tiny slice left at the end and the loops are all off-set slightly.  If I use an option to slice into a specific number of equal size chunks it's a little better but still drifts enough that (for instance) the first hit of a loop is missing it's impact.

So with all that said:  Am I dealing with "tempo wobble" from lsdj in bgb, poorly trimmed wave files, or tools that aren't up to the task of slicing "big" files?

My Gambatte version is 0.4.1
It come from "svn checkout http://gambatte-opendingux.googlecode.com/svn/trunk/ gambatte-opendingux-read-only"
I modified it and put it in https://github.com/yoyz/emulator

In this version which works on opendingux for dingoo A320 the save file for lsdj is 128K so it's okay.
I have no issue with it.
I use lsdj 3.7.4

The latest LSDJ, 4.7.3, is what I've been working with. The .sav file with the same loop I demo'd before is here, but I've honestly had the lagdragsag issue with every uber-simple project I've started / played with so far in BGB. Let me know if anything comes to mind since it seems like you have pretty decent experience with LSDJ on BGB yourself.

Could you tell me the LSDj version you're using and share the save file with me?

Yeah, and that... by default BGB was set up to prefer GBC emulation. I had the problem from the getgo. So I've tried switching that around to every possible emulation mode as well, no difference.

I am using what appears to be the most recent version of BGB (1.4.3) and what, far as I can tell, is the most recent Win32 build of Gambatte available to me (r537).

From my machine, here is a 39-second sample of 2.5 quick passes through an eight-bar song in BGB 1.4.3, with, like I said, no tables / vibrato / really ANY note commands nor demanding timing requests, groove table still set to default 6/6. Just two pulse channels and one kit, all entered in simple sixteenth notes in the phrase editor.

In addition to sort of less-than-tight timing in general on the sixteenths, you'll hear each loop pass has a different spot midway through where the tempo goes super-saggy for at least a bar or two. This is direct BGB .wav writer output.

I would also think the exported wave file should be "sample perfect." It MAY in fact be sample perfect, with the problem happening somewhere in BGB's emulation itself.

Maybe record a small sample for us or something?
I don't think I've had any sort of problems.

The exported wave file should always be sample perfect, even if the audio playback is not. As noted in the thread I linked to, there is a bug in versions prior to 1.4, and you should upgrade. Other than that, the timing should be as consistent as it can be on a Gameboy with respect to CPU load. (In other words heavy use of tables and vibrato and such.) Using GBC a the emulated CPU will give you more GB side CPU power.

And as for Gambatte and the save size, I haven't experienced that problem. Again, could it be that you need to upgrade to a later version?

I'm attempting to use the latest LSDJ, 4.7.3. Gambatte version = r537 build, also the most recent Win32 .exe build I could easily locate.

BGB and Gambatte are creating differently-sized .sav files and I believe this is the issue - according to the manual, the file manager will only be usable on carts with > 1Mbit SRAM available, and otherwise you get the "reset memory" command instead. Gambatte seems to create a 32kb .sav no matter how many times I delete the .sav / restart the emu / reset mem, and BGB uses a 128kb .sav file.

I don't think the .sav size is user configurable in either emu. Have been looking to see if there are any docs to create an .ini for Gambatte and force the .sav size larger, but so far, no dice. If you can let me know what versions of both LSDJ and Gambatte *you* are using, that would be helpful too and I'd be very grateful for a chance to try it.

I won't be performing live, light recording is a possibility. However, I think you may have misread my query - I'm not trying to sync two virtual instances (neat that you can do that, though), I'm trying to get ONE instance to run with correct / consistent timing. I dug into BGB's prefs last night and played around with just about every possible system-relevant setting for a full hour but nothing helped. Gambatte was pretty much locked in right off the bat, but now we have these other problems, and I wish I could get BGB working because the multichannel .wav export would be really handy at minimum.

Are you trying to use this for recording or live performance? You can do two things, sync two instances of BGB using a virtual link cable, and export audio. If you want to export audio from two instances of LSDj running synched, you snould combine these methods. If you just want the two instances to stay in synch between each other, just using a virtual link cable would be enough. It's all described here. Study it carefully.

I have seen two different issue on this emulator :
- wave channel works really well for an emu, especially sample ;
- I think it's the S command on wave channel which sound different, not a problem at all, but it's a little weird and you could do great thing with it ;
- on the gameboy there is some kind of natural low pass filter which give a warm sound,  gambatte sound is different, the sound is... More mettalic I think. I can't describe it. It's not a problem on some sound especially the noise channel. I like it on some song dislike it on other song.

I Will look at it. IIRC I had no problem saving multiple project on lsdj with gambatte.
It works, but I don't recommend using gambatte savestate AND lsdj save/load project at the same time.
it become a mess to understand because there is two different level of "save" which is annoying IMHO.
Could you send the version number of lsdj you are using ?
Check if it is not the demo version on this folder.
Remove the .sav in this folder. I don't know if BGB and gambatte understand the sav file the same way.

I'd read some complaints about LSDJ on Gambatte so I hadn't tried it. The output is much, much more tightly timed than BGB on my Win7 machine. Thanks for that suggestion.

Now the "problem" I have, and I'm not sure what's normal here as I'm new to LSDJ, is that in BGB I can reach what appears to be a multi-song load/save screen off the project menu (following the clean song/instrument) commands, while LSDJ under Gambatte only offers me a "reset memory" command in that space. So it looks like I can only work on one song at a time under Gambatte, maybe (I guess I could use savestates? maybe?). Am I missin' something?
