According to the "Computers and Music" writer in Keyboard magazine, the Amiga has an unreliable timer chip that causes problems in sequencers written on the amiga. I've considered an Atari ST or one of the new A500's to driver my ESQ-1, and while the ST seems to be the machine of choice for synth stuff, the Amiga seems better overall. If the rumors of A500's showing up in mass retailers for Christmas is true, it should be the better machine for long term support too. The only down side to the Amiga is the report mentioned above. Can anyone provide more info? Scott scottw@ico.isc.com

There is no ulreliable timer chip in the Amiga. The issue is the granularity and precision of the system timer services available to the software. Early software developers considered these to be unsatisfactory, but didn't realize that they could allocate one of the timers on the I/O chips for their own purposes. By doing so, they get access to more than adequate precision. > I've considered an Atari ST or one of the new > A500's to driver my ESQ-1, and while the ST seems to be the machine of > choice for synth stuff, the Amiga seems better overall. The Atari ST has been cheaper than the Amiga and is quite adequate for the role of programmable midi-controller, therfore many of the midi oriented developers targetted the ST, while while the developers intrested in programmable systhesis and sound sampling targetted the Amiga. Try to see a demonstration of the Mimetics/Soundscape Amiga software for some interesting crossovers between Midi and sampled sound. > If the rumors > of A500's showing up in mass retailers for Christmas is true... These rumors sound improbable at this point in time. We do intend to sell lots of A500's through the dealer channels between now and Christmas, however. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)

Ah... no. That writer probably used Deluxe Music Constriction Set, which is NOT NOT NOT a MIDI sequencer (even Electronic Arts says so). DMCS is known to crash the machine and cause all sorts of unpleasantries when using MIDI, since the MIDI support in DMCS appears to be a not-very-well-thought-out addition. Many of the other packages for the Amiga, such as Aegis' SONIX -- the sleeping giant of Amiga music software -- and Mimetics' Soundscape MIDI Pro are much better suited to the task, depending on what it is you're trying to do. On the other hand, the Amiga is a multitasking system, and the serial port is not a DMA device. It is possible that right in the middle of a SYS/EX dump, the blitter can decide it needs to decode a track of disk data, interrupting the serial port. It's also possible that you have a number of other processes/tasks running .. in that case, you might see the timing mess up but (at least with SONIX and Soundscape) you won't lose any data. In real life, most people don't/won't run into these problems because of the nature of making music. When's the last time you had the urge to recompile your spreadsheet in the middle of editing a song? I would ignore what the author of the C&M article said. > I've considered an Atari ST A nice MIDI machine, and the Dr. T's stuff is real nice too.

One of the timers are available to the serial port and the resolution is down their in the microseconds. What Keyboard and others have been misled by was the fact that a lot of people use the serial.device to do MIDI, and while it can handle the baud rate it does not timestamp the incoming events so you have to kludge that in. This is generally not acceptable to 'pro' MIDI muscians. David Joiner of MicroIllusions (author of Faery Tale) wrote a midi.device for their upcoming music program. It was written as a MIDI device, doesn't support any baudrate but 31.25K etc etc. Works fine from what I hear. If anyone cares to write one and wouldn't mind putting it out for not too much money I would be interested in it. I have this strange desire to see to new devices written for the Amiga, MIDI: and SYNTH:. The latter would be similar to soundscape's 'speaker' module in that you could open the device and send MIDI events to it and it would play music out the speaker. To turn the Amiga into a MIDI voice box with 4 voices would then be as simple as 1> COPY MIDI: SYNTH: You might want to have SYNTH0 - SYNTH3 for more accurate Audio channel selection. --Chuck McManis uucp: {anywhere}!sun!cmcmanis BIX: cmcmanis ARPAnet: cmcmanis@sun.com These opinions are my own and no one elses, but you knew that didn't you.

It's got build in MIDI, so there are no problems with it on the hardware side. It's also approximately half the price of an Amiga. There is no lack of software for it, as the detractors would have. Dr. T's Software support the ST heavily on the MIDI side, as their ads in Music Technology would have. If you're concerned about other applications, there is now a software emulator for the ST which turns the ST into an IBM clone running at more or less the same speed as a real PC. There is also a Mac adaptor for it. You effectively get three machines for the price of one. And the original cost is quite low. Direct further queries to JSD@UMASS.BITNET... --Jon Drukman

cw@vaxwaller.UUCP (Carl Weidling) was pretty underhanded in his reply
to my article saying "there's nothing wrong with the Amiga as a MIDI
machine."
He posted the first article that said "Amiga has an unreliable timer
chip" but EDITED out my reply (for "brevity" he said) and then said
"you can put up to 4MB on the Atari ST."
Look, if you can beef up an ST, fine -- I stand corrected. But since
the real reason for my posting was to dismiss the ludicrous claims by
some writer who didn't know better, why repeat the bogus info at all?
It was a swipe against the Amiga, intended to promote disinformation.
Look, I'm not anti-ST. If I didn't have a machine already I might buy
an ST so I could run Dr.T's software, which I think is great. I might
have ANYWAY, even though I already have an Amiga, except that they've
told me they're doing an Amiga port.
Had Carl not included the first (inaccurate) quote, or HAD included my
reply with the innacurate quote, that would have been fine. But to do
what he did was underhanded, unfair and just plain misleading.

The only *hardware* difference between an Amiga and an ST with respect to MIDI is the "level conversion circuit to MIDI". The ST has it built in, the Amiga needs one plugged into the serial port. I have personally built the needed circuit, which costs $10 in parts and one evening of trivial wiring. They are also available commercially for $40-$50. So when you say the ST was *designed* for MIDI, lets just put things in perspective. The MIDI standard was carefully designed to be extremely simple to use by many types of devices. Any computer with a serial port can speak MIDI with this simple interface (provided it can support the MIDI data rate of ~32K too). If you're talking about some other aspect, like some specific software package or something, well that's different. But for a person considering which computer to do MIDI with, they shouldn't base it on the presence of internal MIDI conversion completely. Ralph

<<Stuff about my computer versus yours>> I have to disagree about any one computer "being desinged for MIDI" as mentioned in the previous article. In the case of an Atari ST, there *is* already a DIN jack which is convenient that is attached to a serial port. With an Amiga, an inexpensive cord can be plugged into the serial port to provide a DIN jack. In the case of an IBM p.c., some sort of interface card is required to provide an adequate serial port. Depending on the model of IBM p.c. clone, its pre-existing RS-232 port might be able to be used in the same manner as the Amiga's serial port, requiring only an adapter cord. Even an Apple McIntosh (where did they ever come up with MacIntosh anyway? Is the spelling of the edible type of apple copyrighted? 8:-) ) can be used as a MIDI controller. There really isn't anything inate the the architecture of any of the above three computers that makes one better than the other for processing, receiving or transmitting MIDI data. Although, the out-of-the box affordable graphics capabilities of the Amiga and ST are nicer for looking at musical staves (staffs ??) on the screen. Basically all that is required for a computer to receive MIDI data is a serial port capable of operating at 32500 bits/second the ability of the serial port's USART to generate a processor interrupt so that the incoming events may be accurately time stamped. All three of the above named computers meet this requirement. All three computers, in fact, have useful MIDI software written for them. One place an Amiga based MIDI project could get into trouble is if some CPU instensive task wouldn't yield to acknowledge an incoming MIDI event in a reasonable amount of time. I suspect that most people using an Amiga for MIDI input would be multi-tasking unfreindly sotware that would prove troublesome. Ergo, I'll class this as likely a moot area of concern. The McIntosh's multifinder could be a problem since it does not have **true** (preemptive) multitasking (tee-hee). Notice that this article doesn't say which computer I like the best (grin, wink, nod). My theory is that you use what you've got handy, so get to work and use what you've got.

Since the ST dosen't provide such graphics modes, it may not gain from the advantage of having some memory not affected by memory contention when running with 640x400x4 or 320x200x6 screens. But then again, I don't know, does the ST memory run completely without wait-states when it's new blitter is running? If not, then yeah, all ST memory *is* "slow", if so, then I would doubt that the blitter provides the kind of speed the Amiga blitter affords, not being allowed to use the memory without CPU contention during blit operations.

They use the ST because there is no cheaper way to get a MIDI sequencer. Apparently even a C=64 (the previous low-end favorite) costs more once you add the MIDI hardware and whatever else you need to run a decent package. The mid-range favorites are the Mac and the PC/AT (with the Roland MPU-401 sequencer or equivalent). For the high end there are dedicated machines. As for the Amiga MIDI problems, I'd like someone to explain exactly what they are without jingoism (on the part of ST people) or mealymouthed platitudes (on the part of Amiga people). Is it just that people building sequencer programs didn't bother reading page whatever-it-is in the ROM kernal manual that explains how to keep time synch?

>As for the Amiga MIDI problems, I'd like someone to explain exactly what >they are without jingoism (on the part of ST people) or mealymouthed I think the problem is mainly the serial driver currently installed. After all, 303uS per character seems like plenty of time for an interrupt handler to queue to a FIFO. Does anybody know how long the copper takes to setup the video chip at 320x200x4? Secondary problems occur when one is in extremely high resolutions, but assuming the MIDI program only uses something simple, like 320x400x4 (16 colors interlace), this is a moot point. The RBF interrupt (Read Buffer Full) is at priority 5. The only things above it are the disk-sync interrupt (5) and external interrupt (6). Neither of these are used normally. The only other thing I can think of is if somebody is calling Disable() for too long a period of time. Could somebody at CATS fgrep the kernel source for Disable() calls?????

In a multitasking system you cannot guarantee getting the events exactly as them come in (not without giving up the advantages of multitasking). There are timers available on the Amiga which would allow your program to timestamp the events when your program receives them, but sometimes this isn't good enough. The solution ? There are two...(I like this one) write a small, very fast midi.device (which can leave out a lot of stuff the serial.device has to keep around) or set up a small task, running at a high priority, whose task it is to get bytes from the serial.device, timestamp them, and feed them to whoever asks.

It seems very narrow-minded to exclude discussions on computer music, in this age of MIDI, from rec.music.synth. One could start a rec.music.computers group, but since the line between synthesizers and computers gets fuzzier all the time, it seems natural to keep discussions of both together. If one of the main purposes of this group is for musicians to help each other create, then talking about computers is crucial to the group. What is the point in trying to hook up synthesizers to each other and to computers, if you don't know how to use them to help realise your ideas? Talking about the tools of the synthesizer trade is as important as violinists talking about bows or practice techniques. Computer music is still at such an early stage, that many people are still at the stage of playing "chopsticks", as far as sophisticated use of their instruments. I think any discussion of how to use computers better as instruments is greatly needed. (naturally there will be articles that you don't find helpful, but that's true of the rec.music.classical group as well. If you don't like it, you can just turn the page. In the case of the Amiga discussion, most of it has been concerned with the accuracy of the timing capability of the computer, which of course is vital to its use in music. Craig Anderton had a good answer to a recent letter in Electronic Musician magazine, saying essentially the same thing, that you need to really get down into knowing the details of how an instrument or a computer responds before you can get it to express what you want it to express. What good is having a great idea about a piece, if you have no idea how to realise it? People do lose their perspective on the final goal, sometimes - here, making music. But these people may be the people who'll design the next great sequencer. I'd like to hear what they have to say. Rick Bassett CompuMUC <16natiternu

I own an Atari ST and I don't feel that the ST is necessarily 'better' than the Amiga......I bought mine because of the price and I felt that the extra cost (at that time) associated with the Amiga was related to features that I would not find PARTICULARLY useful as a musician..... that's not to say that the features would IMPEDE its' usefulness as a music computer, only that I personally didn't feel that some of them were going to necessarily ENHANCE musical performance....I thought that the features had to do more with other types of processing that I personally am not involved in. Maybe someone with an Amiga can answer Peter's question more specifically, and please ------ no responses from Atari owners . And by the way......my note WAS flaming people who don't provide information. Keitth Hedger

I hate to see the misinformation regarding MIDI on the Amiga. I have used the timer device as the basis for a MIDI sequencer that I wrote for the Amiga. It works fine. In fact, it can easily keep up with the jazz style of a good friend of mine who is not only an outstanding keyboard performer but also knows his sequencers. My friend is the Vice President of Engineeering for a well known synthesizer manufacturer. After playing some FAST riffs into my Amiga sequencer and then listening to them play back, he said "Very cool". So what is all this complaining about the timer device?? -- Phil Cohen (phil@scubed.arpa, sdcsvax!phil)

As pointed out a couple of times, there is no fundamental reason why the Amiga is not fit for serious MIDI use. There is a minor difficulty in the system software doesn't provide a timer service with enough resolution to accuratly timestamp midi events. A number of people have written MIDI device handlers that use one of the available hardware timer to provide this service. The ST has some slight advantage, since it's MIDI port is built in and does not tie up the serial port. However as others have mentioned, it the software that's really the important thing and the MIDI user has to balance the cost, software quality/availabity and any non-MIDI applications to decide which system is best for that user. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)

If there's no MIDI software that works properly, then it doesn't matter if the machine is fundamentally capable of doing MIDI or not, now does it? After all, a Macintosh is fundamentally capable of concurrent multitasking, right? So... the question then becomes... 1) Is there a problem caused by software not timestamping events correctly? (apparently not) 2) Is there a problem caused by software not generating events correctly, presumably because it's not keeping proper time? (This seems to be the common complaint: MIDI events generated by the Amiga not being in sync with everyone else) 3) Is there no problem and most (if not all) Amiga MIDI software works correctly (barring DMCS)? (what I suspect, but do not know) Will someone from rec.music.synth who has experience with MIDI and has seriously looked at the Amiga get in on this? All the technical people on comp.sys.amiga are (quite rightly) saying there is no fundamental problem. What does the real world say? Are the harmonics right as well :->? -- -- Peter da Silva `-_-' ...!seismo!soma!uhnix1!sugar!peter -- 'U` <-- Public domain wolf.

Mac MIDI programs such as Professional Performer uses a resolution of hundreds of units per quarter note. By setting the tempo to a slow 60 beats per minute, (assuming a quarter note per beat), it easily achieves a resolution greater than 3ms between events. If the Amiga, as rumored, has trouble time stamping events with no greater resolution than 20ms, than it's accuracy would be seriously impaired. Small difference in timing have a HUGE different on the feel and interpretation of recorded passages. Just because one Jazz player didn't notice anything amiss doesn't mean someone playing another style of music wouldn't be bothered. Unfortunately, the journalists who made these accusations did not fully explain the technical nature of the supposed problem. Looking at the turmoir that oversite has caused, it was very unprofessional of them to put rumors into national publications. I do not own an Amiga, and cannot confirm or deny what was printed, only that it WAS printed, and distributed over the entire United States. Michael S.
