"don't start the body of your message with any indentation, or it may be eaten" ??????????? This is my first post, and I'm scared... First question: In the same line as the discussion of turning off those obnoxious lattice "ads" - Is there any way to get rid of the Ctrl-C break requester code? I couldn't find a way to do this in the manual (V 4.0) Is this a result of linking with c.o? Second: I've written a lot of code for audio, including a nice waveform editor, and I've noticed a really strange phenomena. If your waveform data is a sine wave (supposed to produce a "pure" tone) there's little to no sound output!! Jagged and sharp noises are PLENTY loud, but sines are not just soft but nearly silent. I've tried this with many different wavelengths/frequencies, but all sines are diminuatively quiet. This is not my computer's fault, for other programs like Sonix work fine - it's sine waves are soft but very audible. My code is based on several book sources, including the RKM's. I hope this is technical enough for this group. If it's not, just tell me and I'll go away quietly :-) .............still too new to have a signature... bdiscoe@tybalt.caltech.edu

Look in the lattice manual under "Break Handling", there are a couple of functions one onbreak() sets a pointer for the break handling, and the more UNIX like signal() call which does the same thing. Pass onbreak() a pointer to a function that returns 1, or use "signal(SIGINT, SIG_IGN)" which will do just that for you. >Second: I've written a lot of code for audio, including a nice waveform >editor, and I've noticed a really strange phenomena.

A check to see that you frequencies are lower than the low pass filter cutoff. (Something like 7Khz) and second make sure you are setting the volume! If you can find a copy get the "AudioTools" from Rob Peck which have some good example routines in them for accessing Audio functions.

(They are part of >the 1988 Developers Conference Notes) If you can't get the DEVCON notes, I am still able to supply that version of the Audiotools disk: $5.00 plus a blank usable disk or $8.00 and I supply the disk: DATAPATH, POBox 1828, Los Gatos, CA 95031-1828. The most important change between version 2 and version 3 (DEVCON/current) is the addition of the ability to synchronize graphics and sound, by which the audio device itself sends the user task a message that a particular note has just begun to play. Prior to that ability, a programmer might have found it necessary to produce graphics, and following the graphics output, send a note request to the audio device. Certainly a less than optimal means of synchronization. And for those of you who DO have the audiotools or DEVCON version, in the doc file (actually an update of the original Amiga World article, I suggested 8 to 10 additional enhancements that I'd like to see or make happen to the tools --- anyone out there take that seriously and patched their version to add these features??? If so, would you care to share it with the rest of us (by sending such additions to me for redistribution?). Like reading SMUS files and other such enhancements. Just thought I'd ask. Rob Peck

I couldn't find a way to do this in the manual (V 4.0) >Is this a result of linking with c.o? To get rid of Ctrl-C code, put a function in your program called ChkAbort() that simply returns 0. This will take precedence over the ChkAbort() func in the Lattice libraries and no requester code will be pulled in. If you simply do a signal() or install a break handler, all the Ctrl-C code will be pulled in only to be disabled by your program. You can check for the presence of unwanted library code by looking at the map of your program - use the 'map hsfx' option on BLink. --- Doug

They can't be turned off for lc & blink. My solution is to run PD make & cc commands. The make is closer to v7 make than lmk, and the cc maps BSD flags to lc1/lc2 flags. Between those two, I only see the blink copyright notices. <mike -- That time we slept together Mike Meyer That's as far as it went mwm@berkeley.edu Yet though we're not quite lovers ucbvax!mwm You're more than a friend mwm@ucbjade.BITNET

Hallo, folks. Got just two quick questions for you...
1) I'm looking for a nice, easy-to-use, INTUITIVE musical editor that I
can use to incorporate soundtracks into my own programs. Ideally, I'd
like to steer away from programs like MED, which force you to talk to
the computer in its own language, and get much closer to a standard
musical program that can handle something more akin to normal musical
notation, or a -translated- version of that notation. KnowwhutImean?
2) Has anybody butchered up his/her Amiga 500 and thrown it into a different
case, like those _terribly_ cute 'Baby Tower' cases that you find PC
clones in? How did it work out? Did you find an acceptable enclosure
for the orphaned keyboard? Such a scheme would make hooking up a
Denise Extender Board and FlickerFixer much more asthetic, and I could
then get rid of a lot of my extra cabling, you know?
Thanks...
