Title: roland s 330
Post by: nochtanseenspecht on June 07, 2007, 09:21:42 AM
anyone ever poured in this baby ??
i thought it might be harmless as it is an open system, the firmware is on a floppy, so
there is no eeproms wich can be wiped....i think
any ideas ?

I don't think it would work because of how the RAM is set up. Its the same with the Akai S612, it seems like it should be good for bending as it can only hold one sound and its 12 bit but when you open it up half the board is taken up with a huge array of very low capacity RAM chips.

For some reason that layout doesn't seem to be able to be circuitbent. I think that like with a lot of digital delays it has something to do with how the RAM is accessed, in that due to the low size of the RAM available at the time rather than using one or two RAM chips to store data they had to spread data out over a lot of chips.

On the other hand i could be completely wrong. If anyone has any real knowledge of how the RAM is accessed on old samplers and delays i'd be interested to hear about it.

I'd try bending it anyway if i were you  ;)

thanks for the advice  :)
hmm...i think of it, but i'm scared to kill it.
will check for datasheets on internet.i guess i'll give it a try later on ( if i'm in the right mood  ::) )
