Well by the looking of your code;

Couldn't the second triggering needing to be later in the interval? I've ber check the pattern sequencer but this is really good information.

I know this is old, but if anything has been done with this I'd be really interested to hear about it! Really cool stuff

If you use a Mac I have a version of it. Found it the other day since any links on here had long since been dead. Seems to be running on Mac OSX 10.10 for me. You'll need Adobe Air to run it, but it's free. A quick google search will bring you right to it on the Adobe website.

Hi guys...
I sent a message to Rumori (BankRobber's author) last week to ask if he was still on board with the editor. He hasn't replied yet, but in the meantime I thought I'd do my own (free) app with a few things I was expecting in BankRobber. It's not a hijacking, rather a continuation of Rumori's already excellent work.
It's still a buggy draft for the moment, but if anyone's interested I'll post a working version as soon as it's usable.
The shortcuts for banks are based on my French keyboard layout. This will be improved when I'll have a working version.

Basically it works like Bankrobber, except you can :
- select a bank and play its assigned pads live on your PC keyboard, and eventually record patterns this way
- slice a sample (not implemented yet) based on its auto-detected tempo
- edit sample tempo
- swap samples from bank to bank, replace or delete samples in banks - play, record and edit patterns (not implemented yet).
A left click on a miniature pad plays it immediately showing its waveform, whereas a right click brings the "Swap/Replace/Delete" popup tool.

I'm not the best dev in town, so there are things I don't master yet, but hopefully I'll succeed and who knows, it might be useful to someone.

That looks amazing please tell me it will run on OSX too ? I'd actually pay for a finished bankrobberesque app.

Ah, sorry for that, guys, I should've mentioned it from the start... Unfortunately the app only runs on Windows since it's written in Visual Basic (VB6, yay, the old-school tool !).
But AFAIK, there's an app on MacOS that allows to run Windows software. Not sure about Linux, though.

OK if we really are going to call this the hacking the 404sx topic then lets start looking at the binary file (the .bin file provided by roland as the firmware)

From trawling with a hex editor looks like it is written in C++

So we can try and decompile or reverse engineer by making small changes and then testing - or we runn something like mess on a computer to emulate the 404sx chipset and then look at the code running on it. (to do this we would need "a dump of the boot ROM(s) and information on what the chips inside are (a scan of the motherboard or some good photos). "

see my comments on this youtube video - https://www.youtube.com/watch?v=ulQo5SjNTaQ

If I understand video description correctly, this guy is controlling emulator through midi out, right? If that's true, we cannot use this trick with 404 since there is only midi in. I'm not expert in embedded, but I think that we can olny emulate hardware, but emulating with all that peripheral components is hard. Also, since we have then flat assembler file only, it could be impossible to reconstruct cpp files, because we miss the information about variables and functions names. Okay, there are some decompilers, but I'm not sure if there will be version for 404 chipset.

PS Do you have some info about RDAC? I found only rdac2wav source, but i really couldn't understand this.

Does anyone here have the schematics/service notes for the SP-404SX?
Not the OG service notes which are available here
