This is the Ultrasound Daily Digest for Mon, Oct 26 1992. ============================================================================ From: dionf@ERE.UMontreal.CA (Francois Dion) Date: Mon, 26 Oct 92 0:54:16 EST Subject: 16 bit instruments for GUS. My sources. Ok, To reply to all the requests: 1- I managed to emulate some Yamaha DX-7 patches and produce some 16 bit samples with a wave and music description tool. It's called Csound and can be found on cecelia.media-lab.mit.edu. If you have access to a Unix machine take the executables, sources, examples and doc from there. If you would rather use it in a DOS (text) system, you'll have to get the executables from bath.ac.uk and get the documentation, examples and tutor files from cecelia. The doc is either in ps or in Macintosh Word 4.0. I managed to read it with Word 2.0 for windows. If any of you have problems getting a working package, email me. 2- Somebody also asked if he could use his dx7 patch dumps ( i suppose it's the 4096 byte dump with 32 patches, 128 bytes/patches). Well, if i can get the info on the format (ie byte 7:fmop1, 8:fmop2, 9: ... you get the idea) i'll be able to do a program that translates these patches in Csound orc files. 3- Another asked if there were other sources of samples... Well there are several other wave generators. You'll have to dig for them. One of *my* source is an EPS16+ keyboard. I've managed to extract EPS16+ Individual Instrument Files from EPS16+ disks. I have not totally figured out the IIF format (file type 3) but i'm working on it. 4- Yet another person wanted to know if he could hear the .pat with playfile. No problem. Use playfile -16 -o1 name.pat This is the minimum options. If you wanna skip the first header use -o335 instead of -o1. (the samples are on a odd offset, after a general patch header, some pointers, and for each instruments if multisampled, there is a 96 bytes additional header). BTW, the .pat are from EYE&I prod. a company who does EPS-16+ samples disks. Also, to play Csound samples use -h -s to generate raw 16 bit. Playback with: playfile -2 -16 -o1 name.snd Again, if you have any questions, dont be shy. 5- Haha. Now you are wondering: Will we be able to use some 16 bit samples as patches? Well, not yet. I'm also working on finding the format. My HP 48s has never been this busy! If any of you are also looking at this, email me. 6- Still there? Another person asked me after i replied on the -2 -16 etc... options of playfile, if there was a way to make the change permanently. i.e. to change signed int to unsigned int, ulaw to unsigned, 16 to 8 bits, 22050 to 11025, 44100 to 22050 etc... Good news for you: you can use SOX. Best sound format exchanger. Support .wav, raw, signed, unsigned, 8, 16, 32, floats, ulaw, alaw, aiff?, 8svx, voc etc... It's probably on wuarchive. Get sox4e. 7- Not finished yet... If you have some disk dumps, instrument files or other sysex dumps or whatever of samplers, get in touch... I'll try to convert those also so we can have almost infinite quantity of quality patches. 8- As you can see we'll definitely need an FTP site! (I have megabytes of EPS instruments that will be in GUS patch format in the near future, and all PD). 9- Request for midi files: the site was posted two days ago. Please stop requesting them from me... Speaking of the devil: i tried to use the midi port... How am i supposed to select it? I have Ultra and some SBP things defined ( how come SBPro drivers are in midi mapper?). How can i select external midi connector? Now, i know midi in doesn't work because Gravis said so, but what about the midi out? Which brings to mind another point or two: 10- Midi cable. I have built one, but have not been able to test it yet. 11- Developper kit: i will receive one in the near future which means that i wont be able to give any more informations on certain points... But i'll finish the patch format, midi cable and anything that's important for you before i get the kit, so it can be considered "publicly know information". For the Unix driver, i'll have one in source form, but it will be licensed so i'll be protected in regard to the non disclosure agreement (i talked to Brad Craig, and he was very cooperative on that point). Last, i have a question. Is Gravis saying that the windows driver is working?? If so, what's the latest version? My version doesn't respond to program changes with any application with the exception of mediaplayer. And even with mediaplayer, the sound is pretty fucked up... (Yes i erased everything, reinstalled and moved the file as said in the readme. But nothing different...) Did i forgot something? Remind me if i did...
