Specs : (from the sidstation.com)

Drummachine style sturdy aluminium casing 
Highest quality in all components 
Motorola CPU 
Potentiometers using cermet technology (not coal!) 
Rotary wheel for easy dataentry 
etc..

Another article which claimed this chip to have the same cpu specs as a
modern synth..
which does DSP and analogue modelling! ..

Well, well... I must have overlooked it. Daniel?

afaik, the motorola is responsible for updating the SID at 200 times
per/sec ..
that lil old chip needs to be forced to do that right? since the c64 was
1mhz..

but what else could it do? .. will the future OS offer more ways (within
software)
to manipulate the SID?

Also -- sample playback.. any chance of sending sounds to it via midi?

Uhm well, probably not. The processor in use in the SidStation is a
68HC11A1fn - a microcontroller running at 2MHz. All written in 100%
20.000+ lines or assembly language. Extremely efficient, but I'm afraid
there is no room for DSP or analogue modelling. :)

The SID-chip is still running at 1Mhz. We're using latches together with a
PAL to control the programming of the SID-chip which is appearently
running at a different speed than the main processor. The extra power of
the HC11 allows us to run a complex synthesis engine which is updating
the SID-chip up to 200 per second, updating the user interface, and
handling MIDI at full speed.

There is no problem updating a SID-chip many times a second, even on a
C64. The problem is updating the synthesis engine which is quite complex,
running for instance four nifty LFO's and tons of software
counters/envelopes.

Actually the CPU is pretty much stretched to it's limit as it is. You can
notice this when setting the update speed to 200, and enter the main
screen where the SID-logo is scrolling in. It will be rather slow. :) At
least you can see I've made a decent process scheduling as the responce
time never is slowed down - just the user interface.

Could be done... Just a matter of taking the time to do it. Would be cool!

YES!!! Finally I have something at 2 Mhz and can still boast about it as well!

true lo-hi-fi-tech!
brilliant :)

ah yes i saw this :) .. 
great work with the assembly (are you an ex-c64 scener??) :)

>Could be done... Just a matter of taking the time to do it. Would be cool!


great! .. so how would it recieve the data?

Of course! :) I've spent many hours coding demos, making sound editor and
music on the little box.

> great! .. so how would it recieve the data?

SYSEX would be the obvious way. There is a standard for dumping samples
over SYSEX I think.
