Using Programmed PIC micro Controller

Using Programmed PIC micro Controller

2009-08-07 by Colin Peiris

Dear Friends!

I would like to sudjest that a programmed Pic micro controller or an EEPROM can be adopted to boot up the emax key board instead of Floppy or other methods.

In this regard you have to modify the interface so that u can read the eprom or controller to boot the emax. So any abel body can experiment in this method.

Any ideas about this very much appritiated.

Thanks

Colin-

While in theory, booting from some other method is possible someone  
has to develop this new method, and that takes time, and $$$.

I have searched for days on the Web trying to find tools to pull  
apart / debug / trace the NS32008 code.
I have not found any of the Assembler language tools or reference  
documents for this CPU anywhere.
That includes searching websites in foreign languages and translating  
them where possible.

obsolete CPU and documentation is out of print are the replies I have  
gotten from potential sources.

Do you know how to successfully load a foreign format (not PC  
compatible) OS image for a different CPU machine code into the EEPROM  
or PIC so that it can be read correctly by the Emax native NS32008 CPU?
If you have the tools and reference documents for the NS32008, please  
share!!!!!!

I wanted to increase the # of available sample banks and size of hard  
drive, and increase the possible available Emax memory by tearing  
apart the firmware and OS used in the Emax.

Please note, the floppy or "other methods" you speak of are necessary  
to load sound sample banks into the Emax.
Emax has no built in sounds.

The facts are that MIDI is slow to load samples. :-(
Emax doesn't support SCSI dump standard. :-(

That leaves RS422 sample input (not as slow), and the analog input  
(realtime sampling).
Then you have to save off your work if you change the samples in the  
Emax.....

The methods work, but are not nearly as fast as having a hard drive,  
CF, or Zip to load many banks from, when desired.

While it does cost some $$ for a SCSI update (where desired), and  
available floppy options (either my slim floppy, or original  
replacement from Route66, or if you know how to modify a standard  
drive to Floppy ID 0)---
These are proven options. They work.

If the idea for a new boot process does not incorporate some form of  
technology that is current using removable media to interact with  
multiple sound banks, and is inexpensive to implement, I just don't  
see it being a viable solution.

My 2 cents.

What about something like this to replace the floppy drive with a USB flash drive?

Re: [emax] Using Programmed PIC micro Controller

2009-08-07 by Ted Summers

Have you tried this with Emax?
What is the cost?

Is the floppy ID # 0 on this unit? IF not it will not work "out of the  
box" with Emax, it would have to be modified.

Is it compatible with DS/DD disk size, as it mentions 1.44MB which  
Emax is not compatible with (Emax is 720K disk size).

Looks like this is reading /writing DOS / PC format to each disk  
directory.
That makes it easy to work with on the PC.
Emax has its own format.
There would have to be a driver written to write the raw disk image  
into each Floppy disk directory.

Just my thoughts having reviewed the PDF.

While the idea is not a bad idea, I just think there is a little more  
to it than slapping in a unit like this.
If it were easy, someone would have done it - like me.     :-)

Esynthesist- any thoughts?

Regards,
Ted

Its not exactly cheap, but USB flash drives are.... If this could boot the Emax and work with the 
floppy controller and 800kB disk format then it would be a great solution! The 100 floppy images 
are stored on the USB drive as files that can be easily archived when the USB drive is plugged into 
a PC or Mac :)

Re: [emax] Using Programmed PIC micro Controller

2009-08-07 by tu@...

No, I have not tried it with an Emax, I just saw this mentioned today on the Waldorf mailing list. 
The price is approximately $USD350. 

According to the manual there are jumpers that set the disk drive mode.  I don't know if that 
relates to drive ID or something else. 

It may be worth emailing the manufacturer with more detailed questions at info@...

Re: [emax] Using Programmed PIC micro Controller

2009-08-07 by jammie

if there is enough room on the boot rom it can go on there 

just need to have an instruction to boot the reason they put os on floppy was because that way they could change the os when ever with out haveing to reflash the rom

on the akai,s they installed it on there rom with the instructions to rewrite os to flash rom

with the emax rom you would need to take out rom reformat it the reflash it it would be alright to do this now as there is no new os for it

Re: [emax] Using Programmed PIC micro Controller

2009-08-07 by mr julian

...I think the problem is, ted looked very hard and couldn't find the 
datasheet (and therefore the opcodes) for the microprocessor the emax 
uses.. and without anyone knowing what the opcodes are, no disassembly 
or hacking is possible.....

so to modify the emax to boot off a different kind of device, or handle 
more banks per disk, you'd have to replace the main microprocessor, and 
rewrite everything from scratch.

that's do-able, but wouldn't exactly be fun...

Yes I agree to all what u said. But as an experiment I thought I must see whether I can implement this method. If you recall the past BBC Micro technique, they have used this rom booting method. not only for booting to use some software packages.

While going through this concept I thought I must learn about this a little and see whether we can do something about.
Also I publish this in order to collect some information.

Also Ted I near future I may order one converter kit for me to use in my emax. Still I couldn't find a slim floppy.

Re: Using Programmed PIC micro Controller

--- Hi Julian thanks for the info.
But the emulator or converter just do what the existing processor wants. So, I think u need not to worry about the processor just mimic the floppy. that is what Tod must have done.
Best regards

we would need to ask emu for the assembly langauge and opcodes but if they are like ensoniq then they will say no

Re: [emax] Re: Using Programmed PIC micro Controller

2009-08-07 by Ted Summers

No I did not mimic a floppy-
I bought the emax schematic, determined how Emu interfaced the floppy  
(schugart interface, not standard PC), took a floppy converter board  
that uses slim floppy, and modified it to Schugart spec.

Anyone with know-how can do it.
But since most musicians are not necessarily Electronics tech, I  
provide the floppy converters so that it is a plug and play solution  
for them /us.
I could have done the mod 2 x for my own emax and never told a soul.  
But that is not in the spirit of this community.

SCSI was available from the manufacturer previous, and I got  
assistance to recreate a valid binary image for the Locking PAL.
That is how that happened.
All I have done there is re-create similar to the original mfr kit.
The SCSI CF drive I use is a standard SCSI drive, no modification.
I am not emulating anything.....

BTW- you can get a brand new CF drive for a lot less than that USB  
stick thingy, though it does get about 30 more banks.....

But I got my CF drive for like, $5 or $10 used. It does happen, you  
just have to get lucky, keep searching.

As it is, you can get into a more modern type of media for a lot less  
than $350.

I dunno where you are located that you cannot get a slim floppy / scsi  
drive.

ebay is worldwide.

I helped someone else find a slim floppy in germany on ebay for  
germany for less than $10USD.
Here they are less or more depending on used or new.....

As to the assembler, stuff - Rob at Emu Archive said he spent more  
than 2 years trying to get those binaries for the SCSI.
I doubt they are going to let the OS go- if they even have the  
assembler anymore.... look what happened with the SE update disk, and  
the memory expansions for Emax 2......we thought they were gone  
forever....

BTW- did anyone win that unused mem expansion on ebay for Emax2? what  
happened with that.....


Regards,
Ted

Re: [emax] Using Programmed PIC micro Controller

The Emax main CPU is a National Semiconductor NS32008 and the data sheets are included in the NS32000 Family databook, which is available for free 
download from http://www.bitsavers.org/pdf/national/_dataBooks/1986_NS32000_dataBook.pdf

I think the issue is more that without the OS source code and documentation it is a long and grueling task to go through the OS binaries to disassemble 
them and understand how they work. There will no doubt also be various design constraints that can only really be discovered by trial and error when 
you don't have the original design documentation. Then you still need an assembler to reassemble the modified code.... but it can be done...

Sadly, you cannot easily build one of these floppy emulators and I don't have any to give :P If you 
want one you will need to contact the company that makes them!

actually with the opcodes it should be very possible to disassemble the 
  code, and make changes... yeah it'd be a bit of a slog, but not really 
much more than what esynthesist already did with the sample format.

and people have already done this for other samplers.

especially if you're just looking for something like the HDD code, to 
enable a wider range of SCSI devices, bigger sizes, and more banks... or 
the boot code, to put the OS onto an eeprom.

You'd just need to look for memory accesses at the location where the 
related hardware is, and then poke around looking for what interacts 
with that code.

Emax 2 vs kurzweil K2500 Sampler

Can you tell me if the Kurzweil K2500 with sampling option is as nice  
a sounding sampler as Emax 2
Anyone own both

thanks in advance

Re: [emax] Emax 2 vs kurzweil K2500 Sampler

2009-09-13 by Tristan

Hello David,

Yes, I own both. The K2500 operating system and features are much more
sophisticated than the Emax 2 and the sound is also quite different.
The K2500 sample playback is very clean, and can of course be
processed by the VAST DSP engine, but lacks what I can only describe
as the grain and bite of the Emax 2. The K2500 can also only transpose
samples up about one octave (or two at reduced fidelity) whereas the
Emax 2 can go up 5 octaves. But the K2500 supports 44.1kHz and 48kHz
sampling rates and the sampling option provides digital I/O. When I
originally changed from an Emax 2 to a K2000 I must admit I was a bit
disappointed by the sound of the Kurzweil, but at today's prices you
can easily afford to have both :)

Re: [emax] Emax 2 vs kurzweil K2500 Sampler

2009-09-13 by jammie

i own both the capabilities of the k2500 blows the emax2 away it has superior synthesis functions and with 128 mb of ram you dont need the sampling option as its better to use the conp and then save as wave files as the kurzweil loads wav files you only need the sampling option if you are going to sample instruments direct in to the k2500

i dont use any of my samplers inputs any more but use the converters on my sound card as they are far superior then any samplers i then use awave to make instrument files for my samplers and exmp for the emax1/2 i also use awave robot for my lopping as its got the best looping engine i have ever come across

spectral synthesis is good on the emaxes transform is good aswell but i use it on the ex2 sampler as its much faster  you can pick up a k2500 with a kdfx for about £400-500 were as a 2mb emax goes for £100 and the 8mb version £200-400 its up to you or go for a k2000 which has the same engine as the k2500 but does not have the kdfx and is only 64mb sample ram you can get one of these from £100-250 depending on condition

the sub systems of the kuraweils are windows compatible so you can stor krz or k25 files on a pc and just move them across to a media format ie zip or hardrive or ramcard depending on what drive you have installed to you k2500

and awave studio you can make patches with upto 3 layers per patch and you can make massive banks with only a few samples useing variations of parameters and fx

it also loads ensoniq files roland files and s1000 akai files and wav

you can also use single cycle wave forms and use the synthesis functions to warp and transform them so you can make a lot of synth sounds with very little samples in memory its like having a vsti softsynth in your hardware and it came out way before vsti did 

personally i lke both synths but to me the emax1 is better than the emax2 for the analog warmth of the filters all be it tiny memory size but i use single cycle waves any way and use the synth section this way you have unlimited memory and layering to samples with diferent panning settings can give a very large sound and using more channels with the same samples and pitching them slightly to get fat unison sounds

Is this the same thing as the "find" loop function in Awave Studio?

I discovered "wave robot" , but haven't come up with anything

Thanks Tristan
What interested me about the K2500 is early Autechure used a K2500RS   
and they claim that is their best sampler for mangling samples at the  
time --late 1990s
I did notice that the sampling on Emax 2 contains that magic grain  
much like the SP1200. EMU lost it with the Emulator 4 series
I bought the K2500 keyboard USD$400 ---I like the keyboard and  
appegiator.
One advantage is you can send midi notes out in the appegiator but one  
the otherhand you cannot clock the appegiator to midi clock directly  
unless you go into dequencer song mode and record it as a sequence--- 
go figure
In the Emax 2 Appegiator you can clock to midi clock but it does not  
send midi notes out


cheers David

Re: Emax 2 vs kurzweil K2500 Sampler

2009-10-09 by Reinaldo

I had a K2500RS and I didn't like it. I could see why people did but no my kind of texture. Too complex, too many perameters, too many options that no one actually used. If you were an actual programmer kind of person the machine is awesome. But for me was anoying and everyone who had it barely pulled something different out of the presets already had. 

Personally I like the Emax II beter even is an inferior machine but is simple and to the point. For me is more fun to use, is more towards live performance and music rather than programing.

Re: Emax 2 vs kurzweil K2500 Sampler

2009-10-09 by nonlocalmusic

fwiw the period of Autechre that I've most enjoyed (amber to chiastic slide) is super heavy on the ensoniq samplers eps/asr10.

The k series samplers certainly can do a lot interesting processing, but they are not nearly as immediate or fun to use as an emu or ensoniq.

I love the E4 series.  Maybe not the best for grainy, but not surpassed for creamy smoothness. fantastic filters and sick bass!

I'll second the notion above tho... with the prices for hardware samplers where they are at today -- if you're making the choice to use hardware, you may as well buy one of each and use them for what they particularly excel at.

Depending on the market where you live, one could buy nearly all the top samplers for the price of one midlevel board ten years ago.

emax $40,  e4xt $50, s770 $150, eps $150 ASR10 350, MPC60 $450, s950 $150 k2000 $200, .   

The s770 alone listed at $13000 when new :-O

Re: [emax] Re: Emax 2 vs kurzweil K2500 Sampler

2009-10-09 by Brooks Mosher

fact:

you can do a lot more on a K2500 than any of the other mentioned samplers.
with all the functionality it offers, it's like the swiss army knife of
samplers.  not too mention, if you're into techno that comes out of Detroit
you should know that a lot of producers used the K2000 (Carl Craig, Kenny
Larkin, Anthony "Shake" Shakir...).  they're really more than a sampler;
they're hardware DSP machines that sample.

my opinion:

they are punchy sounding but definitely lack the warmth of Emu samplers such
as the Emax or EIII.  i've always thought the K2000 to have somewhat of a
colder metalic quality but that could also be the internal ROM sound set
(really nice strings on it though).  contrary to other opnions i found the
K2000 to be quite immediate and easy to get what i want out.  you can do
whole tracks with one as well (unlike an Emax)...

Re: [emax] Re: Emax 2 vs kurzweil K2500 Sampler

2009-10-09 by jammie

i own a eII eIII emax and emax2 and e4ultra 

i own a k2000 

i own a number off eps16+ and asr10

a bunch of akais

roland s330 and s760

korg dss1/ dsm1

and mirage

each has its qualities the others dont 

the k2000 is very easy to use and having 64mb memory helps you can have upto 3 layers to 1 instrument so you can get fat sounds and the dsp synthesis function are great you can take a single cycle waveform and use a choas dsp function called wrap and just by setting the wrap you can warp the single cycle into new unheard of sounds theres a lot more filter types to 

its all in the programming

the down side to the k2000 is the tronspose function of a sample you can only double the root when sampling at 48khz as the top most playing capacity is 96khz so you need more samples when using multi samples but having 64mb this does not matter plus its 16 multi timbral

the good thing about the emaxes is they use special voice chips that deal with the transpose function so you can layer 1 sample across the keyboard if necessary this is good as the memory is small

remember the emax2 is digital just the same as the k2000

and saying that the emax2 is warmer is obsurd 

now if your talking about the emax1 or the eII or eIII then these are much warmer as they are analog filtered out put with digital oscillators

the korg dss1 is another fat analog digital hybrid but this has the ability to sync its oscillators 

the eps16/asr 10 are another great pair of samplers that can do transwave synthesis this is like owning a ppg wave in your sampler as you can do wave sweep modulation which allows you to sweep through a wavetable sample 

roland have the best sounding digital resonance filter of all the digital filters in any synth its a very brash warm filter 

the e4 series filters are great as they are able to do filtration that no other sampler can
and on the software version you can create your own

the mirage is totally aliased digital crunch through warm analog filters and are great for drums for that retro hiphop sound nasty by janet jackson thats produced on a number of mirages

casio fz1 has nice warped digital filters and was a fave of the early drum and bass and hardcore scene

i use all of them because each is special in its own way and every one of them has its own sound its all in the programming and how you want to percieve them 

you can make any sound analog by using more than 1 layer and variating a few cycles of waveform and then changing the fase slightly from 1 another and detuning a little bit to the other sample so that you get a small bit of drift between the oscilators 

but in this climate you can pick up hardware really cheaply

    fact:

  you can do a lot more on a K2500 than any of the other mentioned samplers.
  with all the functionality it offers, it's like the swiss army knife of
  samplers. not too mention, if you're into techno that comes out of Detroit
  you should know that a lot of producers used the K2000 (Carl Craig, Kenny
  Larkin, Anthony "Shake" Shakir...). they're really more than a sampler;
  they're hardware DSP machines that sample.

  my opinion:

  they are punchy sounding but definitely lack the warmth of Emu samplers such
  as the Emax or EIII. i've always thought the K2000 to have somewhat of a
  colder metalic quality but that could also be the internal ROM sound set
  (really nice strings on it though). contrary to other opnions i found the
  K2000 to be quite immediate and easy to get what i want out. you can do
  whole tracks with one as well (unlike an Emax)...
