Does anyone know of a good source of this stuff? The Zoom is REAL nice, but I need more knobs to twiddle.

I've been thinking of making a D/A for my PC, I found a chip that seems to be the right thing (TDA1541AS1N, 2 chan,16 bit with error correction) but I need some advice on how to hook the thing up; particularly help with i/o addresses and machine language to get it to work. I think I can write the programs to generate the data though My knowledge of electronics is a bit limited but I'd appreciate recomendations on books. Also I've heard a bit about the motorola DSP56000. Is this a bit of what I'm looking for? Does anyone know where I can get one and how do they come? ------------------------------ Date: Wed, 11 Sep 1991 00:00:43 CDT From: Bill Huston Subject: DSP chips, etc RE: Richard Humphries/advice needed on D/A and DSP for PC The Moto 560001 only does fixed point, which may or may not be OK. I'm just learning about DSP and I know there's lots of integer based stuff out there, but it just seems to me that floating point must be better. This chip has an advantage: This is that chip used in the NeXT, which may mean cool software which you could port (comp.sys.next?). I'm looking at building/buying a similar setup, but I'm probably going to use a TMS320C30. If you call TI at 1-800-336-5236, ext 3528 and give them your address, they'll send you a big box of data books FREE (the same ones found in bookstores for >30$ each; cheaper binding). They even offer a developer's board for around $1000 stuffed and tested, but without much memory. I'm looking around for other board makers.... BTW: Those DACs sound great! Who sells them and how much? 16 biters are tough to find.

Its part number is TDA1541as1n and they will send you some info on it if you call 1-800-digi-key. It's price is $78.57, but it seems to be worth it, it needs very little external circuitry ------------------------------ Date: Fri, 13 Sep 1991 08:29:00 EDT From: cbema!wbf@ATT.ATT.COM Subject: advice needed on D/A and DSP for PC Attention: Richard Humphries!

Dannenberg" Subject: Re: CMU MIDI Toolkit >From EMUSIC-D, in response to the extremely-belated vol. 38 of the >digest: The CMU Midi Toolkit for the Mac has been in an incomplete but often-used state for a number of years now. CMT is distributed by the CMU Studio for Creative Inquiry, Carnegie Mellon University, Pittsburgh, PA, 15213. For $20 to cover our costs, we will send you two disks including source code and an 80 page manual. There are several versions available, although we have only supported and documented two: [Lattice C, IBM AT/XT/PC, Roland MPU] and [Aztec C, Commodore Amiga]. Others that we have distributed on a strict "as is" basis without specific documentation are: [Microsoft C, IBM AT/XT/PC, Roland MPU] and [Think C, Apple Macintosh]. CMT is also available via ftp from g.gp.cs.cmu.edu. Start with the file /usr/rbd/cmt/README. N.B.: this is a protected machine. You CANNOT cd to and run ls in arbitrary directories. You CAN cd directly to /usr/rbd/cmt. I haven't kept up with the new release (4.0) of Think C, and new implementations of the Mac, but with help from Damon Horowitz this summer, we're close to a new release. One of the last things on the to-do list is switching from our home-grown drivers to the Midi Manager. Now that I know about Nick's code, I'll see what I can do with it. CMT (especially the new version) is much more than just a midi library. I hope you'll check it out. - rbd ------------------------------ Date: Fri, 13 Sep 1991 12:54:01 EDT From: "Roger B.

Thanks, Bill! - JM] ----------------------------Original message---------------------------- No problem with forwarding message to the list. Here's an abridged copy of the documentation. LIBRARY MASTER PROGRAM INFORMATION Copyright (c) 1989 by Harry Hahne 1. Program Description: LIBRARY MASTER is a Bibliographic and Textual Database Management System with special features which make it useful for anyone who needs to organize a large amount of textual information. This includes writers, teachers, students, librarians, researchers, scientists, lawyers, ministers, public speakers and many others. LIBRARY MASTER makes it easy to keep track of thousands of books, periodical articles, corporate documents, manuscripts and recordings and to create properly formatted bibliographies from these works. It also allows you to take notes on these works when doing research in preparation for writing. Unlike most database programs, LIBRARY MASTER does not require you to know how much information will go into a field when you create the database. All fields are variable length and may be up to 65000 characters in length. Many different record types may be included in one database, allowing you to include records which require different fields. Hence a bibliographic database may include books, journal articles, articles in books, theses, reports, audio recordings, video recordings, and other types of records. Data entry is very much like working with a word processor. It allows easy input of accented Western European language characters. Data already entered can be easily changed. 2. Hardware Required: IBM PC or compatible with at least 384K of memory (512K recommended) and DOS 2.0 or higher. 3. Major Program Features: *Flexible Data Structure *Simple to Learn and Use *Rapid and Powerful Searches *Flexible Report Generation *Data Security 4. Typical Applications: *Personal Bibliographic and Research Management *Professional Library Management *Churches and Ministers *Other Database Applications 6. Purchasing information: For more information or to order the program, contact: Balboa Software 61 Lorraine Drive Willowdale, Ontario M2N 2E3 Canada (416) 730-1896 BITNET: HAHNE@UTOREPAS A free demonstration version of the program is also available.

I know that Apple makes one for about $100, and I have heard of another one by Aztec, I think, that seems to be available for about $60. My intention is to run a "home keyboard" (in this case possibly Yamaha PSR500) using the program Deluxe Music Construction Set. Any suggestions, advice, or comments would be appreciated. Thanks.

I've had good lu ck with Midi-=Translator (Passport Designes?) available from mailorder Mac houses for about $40. Good luck! ------------------------------ Date: Fri, 13 Sep 1991 07:59:00 EDT From: Mario Vergona Subject: Mac Midi Interface hi I just received a catalog that has a listing for a MAC JL COOPER midi interface. It works off of the serial port and comes with the connecting cables, all for only $60. Given the rep of JL COOPER and his products, like the FadeMaster, etc this is a very good deal for all you Mackers. m p.s. as an aside, does anyone out there have a feel for the used price (but in its original box and packing material, hardly used) for a ROLAND MicoComposer MC-202. It is a pre-midi device with CV input/outputs. It is a module with a mini button keyboard 2 oct builtin. It has a number of slider switches and a builtin sequencer. ???? m ------------------------------ Date: Fri, 13 Sep 1991 11:09:51 EDT From: Brian Adamson Subject: Re: Midi Interface for Macintosh Carl, The Altech interface is as good if not better than the Apple interface.... The current Alltech that is. I had an older Altech interface which was poorly designed and failed eventually. I took mine apart to repair, and took a friends interface part to compare. Although they looked identical on the exterior, my friend's (a newer interface) had a different design which made more sense to me, So, scavenging parts from my poorly designed, defective interface, I rebuilt mine, which works perfectly now. I have a a complete schematic in MacDraw II (or MacDraw Pro if you prefer) format. It's simple to build, only a few parts, probably costs < $20 to build (use a VHS tape box for the case).

Here's a question for users of MIDI Manager: Are there problems using MIDI Manager programs with old address-the-serial- port-directly MIDI programs on the Mac? That is to say, not using them simultaneously w/ the patcher but as follows: What happens with these scenarios: 1) Use a MIDI Manager editor/librarian, then switch, under Multifinder, to a non-MIDI Manager sequencer. a) both using an interface on the same serial port b) using different MIDI interfaces on each port: one for the MIDI manager, one for the traditional program. and c) QUITTING the MIDI Manager application before switching to the non-MIDI manager application. By using two MIDI interfaces creatively, could I run a MIDI manager program which uses the printer port (say MAX doing MIDI effects for example) and then run my non-MIDI manager program (say sequencer) out the modem port to a different MIDI interface, route the output of that interface into the input of the MIDI manager interface (for added MIDI effects). The reason I ask this is having invested in and in love with a non-MIDI manager sequencer whose company is out o' the business (It does work with System 7.0, believe it or not). Just how truly "multi-tasking" are MIDI manager programs? Can I word process to a backdrop of sequenced MIDI music?
