Sounds like the CD Rom drive is set to the same ID as the internal HD. Try changing the number on the CD Rom drive before you start poking around inside the S-770 to change termination etc.
Maybe its the fact that you are trying to use a SCSI2 device. Not sure if a simple cable adapter is all that you need to make it compatible.
Seems like an eternity since i last had to deal with SCSI issues......
Got a closet full of old drives waiting for binary Nirwana

Yes, first try ID and it may be that you need an older CD-ROM drive. IIRC older Apple CD rom drives like the CD300 or CD100 are fine.

Might very well be the situation - as David suggested, an older Apple CD-ROM will work for sure. That said, termination will have to be addressed.

Yeah, no need. I have quite a few Akai CDs too, but for sure, they are nothing compared to native Roland libraries. (in that the Roland ones will use the synthesis engine of the S-7xx/SP-700/DJ-70, and not be simple sample playback).

Yeah, I sure have sampled my SH-2 as well...it's a good one for that.

1 to 4 samples make up a Partial.
the Partial can have basic synthesis params assigned.
then Partials are mapped across the keys into a Patch.
the Patch can then have synthesis params that offset or modify the Partial settings.

So yes, you modify the filter at the Patch level to affect all Partials at once.

Do some research to be sure, but IIRC, it uses a MSX-format mouse. DO NOT use anything other, or you will burn out the port on the sampler.

while on the patch screen go to the com menu and select edit partial. now in the special edit mode or, 'subsidiary mode' (as shown by the asterisks at the top) when you change the edit mode at the top from 'single' to 'global' you can now edit partials globally. this also means that selecting a different sample in one of the four slots will also affect the other partials likewise fyi. without totally copying the manual here:

"it can be a convenience when dealing with multisampled patches. global editing of envelopes, for example, makes it much faster..."

page 127 of the manual


also, while in this mode you can only access those partials that are in the patch you came from via the com menu. selecting to edit samples via the com menu while in a partial page is the other 'subsidiary mode' that functions the same way. once edits are done just press exit and you will be sent back to the patch/partial page you accessed this mode from.

The Roland S-7xx hierarchy can be seen as byzantine, but for the programmer, it also offers a creative environment for timbre creation.

Waveform data that has been assigned an original key, loop mode, and loop points becomes a Sample. (512 in RAM, 8192 on disk)

Samples can be layered, velo-switched, and crossfaded, assigned a filter and amp ENV, tuned, panned, assigned an output and level, keyfollow, and an LFO - once done, you have a Partial. (255 in RAM, 4096 on disk)

Partials are assigned to the keyrange, splits are created, and poly/mono mode is chosen, MIDI assignments are made, and assignments can be made for tuning, output and level, as well as velocity and filter offsets/overrides - this is a Patch. (128 in RAM, 1024 on disk)

Patches can be layered, assigned MIDI channel numbers, keyboard splits and positional crossfades can be created, and once again, output assigns and levels can be set - this is the multimode, or Performance. (64 in RAM, 512 on disk)

Multiple Performances can reside in RAM - and the sum total of what does is called the Volume, and is also the top-level disk structure. (1 in RAM, 128 on disk)

-----

What I like about this system is that you can set up Samples and Partials and then create multiple Patches that use them - each Patch with unique filter and amp offsets/overrides - and those Patches take almost no additional memory. Also, any changes to subordinate objects are automatically carried upward in the hierarchy, as well as reflected across any and all parts of the hierarchy that use the changed subordinate objects.

The CD-Rom drive just arrived from scsiforsamplers and it works fine with the S-750!

...hey where did everybody go?

More arguing and both parties risk a ban..
