No problem. It's your thread and it's not 'old' either, so all good.

I know that with many card readers that certain CF cards present issues with saving samples properly (ie. noise free). Have you tried different cards, brands, capacities?

I have another card, but I believe it's the same brand. However, the fellow who made me the reader recommended this particular card.

However, it seems that it happens without the CF reader or anything plugged into the SCSI port. If I sample 'dead air' into the analog ins, and assign it to a pad, I still get the digital whine / noise.

Well I don't know what it could be, assuming you've done all the basic checks (backlight, invertor, RAM, reseating). Could simply be a faulty component that needs replacing somewhere, beyond my level of knowledge.

well perhaps I haven't. I suppose those basic checks are in another thread here somewhere?

I'll take a browse

well i tried reseating the RAM and it didn't seem to change anything.

It should be noted that the noise only occurs on sample playback. So if I sample, and then hit play (before saving), there is no noise. But once I assign it to a pad, and play back, now there is noise.

I was searching and read there is stock RAM as well as expanders? (i have 32mb). If so, where is the stock ram?

Stock RAM is (was) the EXM3002 module (2MB). A lot of good info in this thread:

It looks like your machine is expanded to 32 megabytes. ( RAM looks like the stuff I purchased from eBay seller Fourniersean )

If this is the case.

Make certain you remove the AKAI EXM3002/EXM3008 memory board ( currently installed in your machine ).

The AKAI EXM3002/EXM3008 memory board does not need to be installed when your machine is maxed out to 32 megabyte.

Leaving the AKAI EXM3002/EXM3008 memory board installed is not necessary as the MPC3000 just "maps it out".

The function performed by an AKAI EXM3002/EXM3008 memory board while its in a "mapped out state" will be that of straining the power supply stages.

Just thought I'd let you know.

If so I have to uninstall that too!

yes i'm aware...was just a joke.

Anyways, ive re-seated every part, tightened everything, still have the same issue. Armen's is pretty close to me, so perhaps I'll give him a ring
