Well, stjohn.gsfc.nasa.gov (formerly castrovalva, hopefully castrovalva again soon) has all of the EMUSIC-D stuff in compressed format, and is both ftp and gopher accessible. I'd like to get all of that back over to AU in some searchable form, but I don't think we've got enough disk space. We do have a number of interesting items at stjohn that probably should be at au as well. I'll have to see if I can make room in my schedule to get them over to au as well. Meanwhile, I have caught up to April '93 on the EMUSIC-L back issues. God, we talk a lot. --- Joe M. ------------------------------ Date: Fri, 28 Jan 1994 17:58:30 -0700 From: Yang Joo Shin <18253@EF.GC.MARICOPA.EDU> Subject: getmusic I wish I could download some fancy electronical music, of computer songs.

Midi out is fine playing all the >sample 'MID' files you get with the software (MIDI PRO), This is good. It means that basically your interface is working and that your synth is responding OK. >but however >midi in is not working. After recording work through the midi, when i >play back the data, it plays all jumbled up. Hmmm. "Jumbled up" how? Are all of the tracks playing back with the same voice or different ones? Are the voices assigned improperly (e.g., what was the pian part is now the drum part, etc.)? Try muting all of the tracks except one and see if the individual tracks are playing back with the proper instruments. If not, it's some kind of a channel assignment problem. Either you've recorded all of the tracks from the same channel, and all of the MIDI data is going back out on that channel when you play back, or you simply need to check that the track assignments are all to different channels for playback. >Could it be a problem with IRQ and DMA settings on my Sound Blaster PRO? No. If this were the case, it probably wouldn't be working at all. >Or could it be my midi channel settings on the keyboard.? This is much more likely. Also, check to see if the sequencer isn't somehow reassigning the channels on playback. You might be recording from channel 5 (say), but all playback is ending up on channel 1. --- Joe M. ------------------------------ Date: Thu, 13 Jan 1994 12:21:26 +0000 From: Buchanan Blake Subject: HELP ME. I am a student studying in Edinburgh. I am having great difficulty in setting up my Roland D5, with my 386 PC. Midi out is fine playing all the sample 'MID' files you get with the software (MIDI PRO), but however midi in is not working. After recording work through the midi, when i play back the data, it plays all jumbled up. Could it be a problem with IRQ and DMA settings on my Sound Blaster PRO? Or could it be my midi channel settings on the keyboard.? Any information regarding this would be very helpfull.

I've looked at the topic and found it interesting to add few lines. >From acoustic point of view human's ear can pick up only freq range -<> 20000Hz. If an device has the same limit of high freq. it will not reproduce sound properly. Lets say we have an square wave with basic freq. 20000Hz and as many know from Fourier Transformate it has harmonics so it can be square not sine... But from second point even if a device will reproduce this wave fully with harmonics out of ear's range and it will be square a human will hear it as sine... What I want to say is that some people hear 20kHz and some 16kHz as you mentioned. And high frequencies by one can be heard differently than another. What's more the human body can receive also vibrations with large ranges of frequencies. Source that will have the same range that ear will 'sound' differently than one that exceeds it...That's why acoustic instruments sound better than speakers etc. Jack L. ------------------------------------------------------------------------ Jack Latanowicz tel/fax Pl-(0-61) 798-202 Ul.Porzeczkowa 27 jack@plpuam11 (bitnet) 61-306 Poznan jack@vm.amu.edu.pl (internet) P O L A N D "'Dancing barefoot' - Patti Smith..." ------------------------------------------------------------------------ ------------------------------ Date: Sat, 1 Jan 1994 17:52:14 +0200 From: Matias Dahl Subject: Re: High frequencies. *>The number of bit is the amplitude resolution of the signal and it *>gives the noise/signal ratio. The highest is this number, the better *>is the N/S ratio. *>The sampling frequency is the time resolution. So, the sampling frequency will simply allow higher frequencies into the sample ? When I have sampled sounds there was a lot of noise when say sampling at 4kHz where does this "noise" come from. Is it the higher harmonics that mess up the sampling ? This noise would then go away if all frequencies over 4khz/2 is filtered away ? Therefore the noise.. ? matte ------------------------------ Date: Tue, 11 Jan 1994 10:53:10 GMT From: ANDY MCDONOUGH Subject: lack of controller WARNING: message contains material that might not be suitable for this forum (sorry, i'll make it quick.) i missed some of the posting on the u20 key problems, but i recently became frustrated with my lync controller (as one key sent erratic velocity) and opened the box. lync, as you may know, is out of business so that helped me make the decision. besides, there was no "qualified technitian" sticker :-) okay, so i had my contact spray ready, but found that each contact had a little condom on it...like a little booty, raincoat, not-something-to-spray. frustrated, but hopeful, i wiggled the little rubber thingy around (gently) with some needle-nose pliers, rubbing what felt like a t.v. remote contact below, and now all is well. ....andy ps for those still reading: lync actually has wood (from trees) parts inside. anybody know why lync went down? what happend to the guys? ------------------------------ Date: Tue, 11 Jan 1994 17:29:14 CST From: FA19000 Subject: MIDI & PC's I want to connect a synth to my PC.

Also, is there >a difference in quality of MPU401-compatible interface cards? > Janice Saffir > Northeast MO State U I do not think 'MIDI performance' is compromised on a 286 or above processor. You can probably expect the same throughput on each machine. The important part is the *program's* (sequencer, notator, editor, etc.) ability to pump data out through the interface card. On programs that utilize Windows, using a 286 will probably be a drag to use, and may compromise your MIDI data stream exiting the computer. All the data will exit, but there may be subtle intermittencies in the data stream. If you are not using Windows software, I doubt there would be a difference in MIDI throughput using a 286 versus a 386 or 486. It sounds like you want to do alot of things, so if you are in the market, a *fast* 386 or any 486 would serve your needs, and would far outweigh any cost:capability ratio of buying a used 286. Hope this helps a little.

I want to use notation, sequencing, and sound editing software, at least. Also, is there a difference in quality of MPU401-compatible interface cards? ----------------------- I used to use a 386 DX 16MHz. This is borderline sufficient for Windows based sequencer programs. Cakewalk 1 is fine. Cubase 1.1 is just about OK and Recording session is no good. The performance with a Windows program is not determined by the data rate through MIDI which at 31 k bits per second is a lot slower than for example a floppy diskette. However what does affect it is the amount of graphics that you try to throw up on the screen and scroll while playing back a MIDI song. I now have a 486 DX 33 which runs any sequencing software OK for playback. Note however that programs such as Finale which produces very good printed musical scores is still slow on this machine. I have both an MPU 401 clone card and a general sound card which includes MPU 401 emulation. All software I have tried runs on the MPU 401. I have not personally tried using the MPU 401 emulation on my general sound card, a Pro Audio Spectrum 16, but I hear from friends and reading on the net that it is fine for Windows programs, but may be a problem with some DOS programs which try to use the interface in intelligent mode rather than dumb UART mode.

Daisy chain is my choice. Put plain and simple, how do I connect them? Also, what tools are available on the Internet to perform text searches on files on a LISTSERV?

SYNTH B is your multitimbral module, presumably set to some base channel (say, 2). -----------< Cognitive Dissonance is a 20th Century Art Form >----------- Eric Harnden (Ronin) or The American University Physics Dept. 4400 Mass.
