Sample Extraction Info

 --------------- INSTRUCTIONS ---------------
There are different file types and they all require a specific way to be extracted, at the end of this you'll learn why I archived everything in WAV format.
Let's start with the easier one, the AKAI files:

---> .iso

Simply open these with CDXTRACT, go to Virtual Drives on top, choose the .iso and click on Disc (right below the big square shaped Refresh button) and then select Convert Full Disc...
A huge dialog box will open, just select whatever format you prefer on top (I always used Mesa, as that gave me clean WAV files) then chose an output folder on the right-top and press Convert at the bottom.
Give it a couple of minutes and you are good to go!

---> .nrg

CDXTRACT is not gonna be able to see through .nrg archives, and because of this, you're gonna have to make use of DAEMON Tools Lite:
Open the program, go to images (on the left side) and drag-drop your .nrg file in there. Right click on it and press Mount.
From this point on, you open CDXTRACT and follow the instructions above, you'll be able to treat the .nrg file as it it was an .iso.

---> .bin + .cue

CDXTRACT is perfectly capable of opening .bin files, but keep in mind if that comes with a .cue file, it has to be in the same directory of that .bin file, otherwise it's not going to work! NOTE: In a fringe case I've come across a supposed AKAI .bin/.cue file that I wasn't able to open. Someone suggested to use foobar2000 and somehow, that worked. That's why I told you to download that program, hopefully this will make you avoid confusing head-scratching moments.

That's it for AKAI Stuff, let's move onto Roland files. Now, while I've managed to open some of it using CDXTRACT, their older stuff is simply off limits. You need their proprietary equipment to hope and extract some audio, I remember finding a website that went into more detail, on top of actually having the samples extracted, I believe it was this one:

Moving onto Ensoniq files, you'll have to use Chicken Systems Translator Pro now. This is a software I started using recently but I can already tell you with confidence that it's kinda trashy. It's unbelievably slow and a bit more unintuitive compared to CDXTRACT. Now then:

---> .iso

Open the program and go to: Tools -> Register Items -> Virtual Drives -> Single... and open your .iso File. It should appear in the tree menu on the left, under Ensoniq. Click on it, look at the screen on the right, select all of the items that appear in that window and click on the Translate button on top. A new window will open, just select WAV or any other format you want and click ok. Get ready to potentially wait for as longas 20-30 minutes, depending on the file, or if you're very unlucky.

---> .bin + .cue

I'll be honest I have no clue how to open these! Found several of these Ensoniq files in .bin/.cue but never managed to open them! Some guy on a forum said you should be able to extract those using an older version of KONTAKT or something like that, before v4.2 methinks. Here's the thread I found: https://audiosex.pro/threads/bin-and-cue-ensoniq-format.27128/
Good Luck!

--------------- TROUBLESHOOTING ---------------
Both of these programs are far from perfect and sometimes weird stuff can happen. here's a couple of things you may want to be careful of:

 - CDXTRACT -
Sometimes while extracting your Samples this program might take an ungodly amount of time and basically lock up completely.
This happens whenever it encounters a broken sample with either their Left/Right channels missing or corrupted. If that happens use the Task Manager to kill the process. Depending on how bad the sample in question is, you can either attempt to salvage it through other software solutions, otherwise you're gonna have to ignore it. Happened to me a few times. Make sure to check your output folder if there are any of these errors, as CDXTRACT will render a huge 1Gb+ audio file worth of silence!!!

 - Chicken Systems Translator Pro -
Haven't used this much like I said, but one time something weird happened. I went to open an Ensoniq .iso and the program listed the thing as an EMU File. I couldn't manage to render or convert the thing at all no matter what, so I just assumed it was either broken or a bug in Chicken Systems Translator

--------------- CONCLUSION ---------------
And that is all I know about this sort of stuff. Probably there are better tools and programs I am not even aware of. I'll leave everything else up to you now. Good luck everybody!
