SuperTrue Software Emulation

Postby russo.mic » Mon May 19, 2014 12:59 pm

I have purchased an Amek Big, and of course the computer has a bad serial port. So, I went ahead and rebuilt the damn thing from a cobbled together bunch of parts I dug out of the back of computer stores. yeah! problem solved!

only not...because the one I rebuilt died. So, in the interests of not having to deal with an old computer constantly dieing, I've had much luck emulating the DOS environment by doing some heavy programing around DOSBOX, a dos emulator for linux, windows, and OSX. So far, I've got most of everything working, only thing left is to get recall working, which is a matter of analyzing the serial output from the software and creating a wrapper to interpret it, then rewrite the data back to the board. Shouldn't actually be too hard, but I've fallen into a project that is preventing me from continuing until next week.

I've so far been ignoring the parallel port, so rupert's voice isn't going to work...for now. The way I see it that is probably a largely unused feature. However, it shouldn't be impossible to get it to work.

Serial communication is being handled by a USB serial adapter, cost around $25. That feeds into a microprocessor unit I've built and programmed to rewrite serial data back into the Virtual Dynamics, TCG, and faders in a way that they can understand. It should be possible to run this along side whatever DAW you happen to be using, or with a standalone computer. You could purchase a cheap little laptop and throw Linux on it and supertrue to your heart's content.

My question is, is there any interest within this small community of having such a thing? I'm developing it for my own personal use, however I'm not the greediest of people. Anybody still using this stuff and stuck with an old piece of crap computer? Best of all, it should be possible to transfer any work on the current machine over to the fake one with relative ease.

It is great that you have spent time and effort on this. I thought about doing this for my Einstein, but since it did not have a working PC with it when I bought it, I ended up just ditching on the automation all together, in leu of just automating in my DAW. I still have the automation system in place still inside the console, and it is fully loaded with dynamics cards for all 80 channels. Maybe it is time to bring it back to life.

I for one would love to know more details of this process. What apps are used and where you got them.
If it can be done fairly easily, I think there are a lot more folks here that would also like to know this, if for no other reason than having a back up plan for when their PC dies and there are no replacement parts available.

Hi,

Yeah, I would be very interested! I have four AMEK consoles, all running SuperTrue software and on old, tired computers that keep failing, LOL.

So what exactly is this system? Is it like a shell program running SuperTrue on a computer running Windows 7 or 8? I think this is the essence of what you are doing, right?

I'm not the most computer savvy person, so pardon my lack of knowledge in regards to what you posted. But my interest is very high!

Regards,

Hi
There is a bit of a problem with desks other than the Big, Recall and 501 in that all the others use an AMEK card inside the PC to communicate with the desk.
Otherwise it would be a fantastic idea to program up a Raspberry Pi or Arduino or whatever which could then even be 'desk powered' and live in the back with practically no external cabling.
Offering an 'IBM' with a suitable flash drive rather than 'clockwork' drive may make things more reliable.
The Big/Recall/501 use one or two pins of the parallel port to divert 'comms' which may be your issue with recall function.
The BIG did in fact start out using MIDI into an ATARI for the first couple of years. The processor in the desk had new code, and the card in the desk at the back with the D subs was added to make it 'speak IBM'. Apart from a bit of voltage translation the processor essentially speaks 'midi' to the outside world although with 'IBM' the clock rates were changed to suit 'com' ports. The processor card was 'upgraded' over the years to get better fader resolution but during the ATARI/IBM transition it was possible to change one to the other with a crystal or two, a new EPROM and a few wire links.

Am looking for a Amek DB25/DB9 to DB15/XLR automation cable or the pinouts so I can make one.

Hi
The information is in the manual in one of the earlier sections concerned with the various connections.
