Memory Management?

I just got my O88 3 weeks ago and am still exploring it. It's loaded with 2 G ram and has all previous sounds loaded except the brand new EXs 3 sounds.

I realize that when you load new factory sounds they go onto the hard disk and then load upon startup.

Currently, both EX1 and EX2 (Steinway) load at startup (thanks to 2 gig of memory).

1) Will the EXs 3 sounds also automatically load upon startup or will I be limited to only 2 EX's being loaded?

Since I haven't yet heard all the sounds (both programs & combis) in all the banks, I'm not sure if all of the banks are currently full.

2) Another question is this: Do the new sounds you load occupy existing program/combi banks that are now blank (if there are any of those?) or do they overwrite existing sounds or do they create their own new program or combi numbers/slots?. Just wondering if you're flushing existing sounds or truly expanding the number of sounds?

Thanks for any help!

If you have 2 Gb of memory you can load EXs1, 2 and 3 at the same time...
You can even change such settings without turning off the Oasys.
You can also set where the programs and combis will be loaded. By default they will be loaded in program bank USER-G and the combis in the Combi bank USER-G also. They don't create any new program / combi slot. So please check first that the banks to be used are empty or save to disk such banks before loading the EXs3 programs/combis.

Rgds.

Programs and Combis are small "reference data" that are stored in ROM so they are available at power up. Programs reference underlying samples (multisamples) and those are either:
-- factory samples (auto loaded at power up)
-- external samples (you must manually load them, and they are erased on power down).

If you create a Program that uses/refernces external samples, you can run into a situation where you can "see" the programs sitting in one of the Program banks but the sounds don't sound because you forgot to load the samples.

I have a number of sampled sounds in both wav and akai format that I might want to move to the O for the sake of convenience. Where is the best place to put them? In the user G bank? Only on hard disk to be called when needed?

As I look through the user banks there are many programs that start with "init....." most of which were based on a piano sound. I assume these are just basically place fillers for the program slots, is that correct? Is it best to put the samples there? And if I do, are these going to require manual loading every time I want to use them as you state below?

All of the Korg keyboard products that include sampling functionality (including the OASYS) use a 2-tier approach to storing sounds:
-- Programs and Combis are small data files that really just store settings. For example, a Program is just a set of data that contains EVERY parameter you see on all of the Program screens. One of those parameters are pointers to real audio samples
-- the underlying samples themselves, which are stored on the internal hard drive.

The program data itself is stored in non-volatile program banks (which means they are reloaded on power up). The underlying samples are handled differently whether they are factory multisamples or your own samples. With the factory samples, they are auto-loaded on power up and instantly available. With your own samples you must load them yourself.

To understand the difference betweeen Program data and the underlying samples, uncheck the EXS 2 Grand piano box, then pull up its associated Program bank and select a program. You will see that the Program data is still there, but your playing produces no sound since the underlying samples are not loaded.

With your own sample libraries you will want to create Korg Programs and store those programs in a Program Bank that is currently not being used. After you create those Programs, which are simply data settings which refer to samples temporarily loaded into RAM, you will also then want to perform the Disk Mode "Save Sampling Data" command, which will store those "underlying Samples" in the Korg Sample format. This will allow you to simply re-load the associated .ksc file the next time you power up.

I would suggest browsing through the Parameter Guide 'Disk Mode' section to help explain this better than I have.

Thanks Martin!

I'm still slogging my way thru the parameter guide and haven't got that far yet. The newest Korg product I had before the O was the wavestation, so I never had any Korg product that sampled. Always used Akai samplers previously.

A few things have remained familiar, but many things have changed!
