Promise I’ll get the Matt Gray bank up tonight and start on a few other famous C64 musicians as a bit of a theme. I checked back on the patch original last night with the intention of uploading it but it was screwed. I *think* it’s bacause I was saving to patch 1 which is possibly like ensemble 1 where you have to kinda leave it alone (?). Dunno.
Anyway, I started re-creating the sounds again and saving to patch 2/ensemble 2, and it all *seems* to be saving OK now.
OK, I’m not uploading this to the correct patch thread just yet as I *think* I’ve found some sort of a bug in the multi mode(?). You can get all the bits and pieces here and maybe someone can confirm that it’s not just me that this is happening to?
OK - first take a listen to the MP3 - this is what the patch should sound like when playing the MIDI file (which is also enclosed). What I am finding is that if I load the oatches into the Sammich, they sound completely wrong (usually on osc2 the ring mod and sync are turned off and osc 3 is replaced by a noise wave)!
To get it to sound like it should, you need to load the patch into MBSID Java editor and double click on the patch so that the editor screen opens. 9 times out of 10 the sounds are as they should be. If not, close the editor page and then double click again until it sounds right.
If you then transmit the patch back to the Sammich and save via the front panel, it still goes screwy when you change select another patch or reset it.
Any idea’s what is happening here? Maybe the osc’s aren’t initializing properly somehow?
As far as I´ve understood in Multi Engine Mode (I don´t use it usually :-)), there are no single oscillators configurable (as you´ve described in the last post), but six different “instruments” that are mapped to the three oscillators of the two SIDs. You can address these instruments via different MIDI channels (and you did that in the demo midi file). You can configure those instruments of course with different oscillators and you did that, so I guess it is just a “naming misunderstanding” in the last post.
When I open your multi patch in Rutgers Librarian
instrument 1 uses a square
instrument 2 uses triangle, sync and ring mod
instrument 3+4 use square with different sustain levels
instrument 5+6 use triangle with different sustain and release levels
Does this match your intended patch? If so, the displaying in Rutgers Editor is correct - also the uploaded patch appears to be identical, when uploaded to a MB6582. I uploaded it by selecting to the appropriate bank slot (A 56 in my case) in the java editor, followed by “file -> load patch -> your patch file” and then “transmit -> patch to memory”. So, no problems in uploading to a MB6582 on my side.
Yes - naming difference I think. What would normally be a SID oscillator becomes a 1 oscillator instrument in it’s own right in multi mode.
Those values sound correct. Now that you have saved your patch into your MBOX, if you close Rutger’s editor and turn off your MBOX, when you turn it back on (and maybe change patches and come back to the Matt Gray patch), does it then still sound the same? If it does, then maybe it’s a saving bug in my Sammich’s (they both do it).
Yes, it stays the same - I navigated to different patches meanwhile and came back to verify…
Are you sure you didn´t just “upload to buffer”? It only stores the patch in “volatile” memory, in that case you need to save it manually from the MIDIbox…
The other upload method (“upload to memory”) directly writes to the bankstick and it should be conserved there for some time…
Hiya - yep, I’m saving to the bankstick not the buffer. I’ve even gone as far as to use the front panel of the Sammich to save the patch. Hopefully someone with a Sammich will chip in.
I tried the patch in both my usual MBSID and in a Sammich, showed symptoms are the same.
I can upload the patch to memory from the editor and it sounds just fine from what I can tell but it doesn’t retain some settings (after saving and browsing patches).
Behavior looks similar to what Tonka described before.
please forgive me my ignorance. what is it actually that makes a Matt Gray bass, technically?
of course i’ve listened to the demo you made and it sounds very cool. I’m gonna try it too as soon as i’ve hacked my sid together again (finally).
also i must admit, i haven’t done anything yet with the multi engine, except for testing that it works. so the discussion about the technical details in this thread is, embarassingly, a bit over my head.
is there an easy way to explain, or would it rather be shut up and try ?
It’s a fairly simple wavetable bass which begins with a high pitched noise wave and then goes into a pulse which is swept from narrow to wide to create hammering basslines which really cut through a mix nicely. I guess the best way is to give an example from the man himself (though *technically* I think Rob Hubbard used this type of bass first in the Sanxion loading music):
