-
- There are no dual DAT decks for under $10k. The lowest cost DAT deck
- currently is the Sony TCD-D7, just discontinued in favor of the TCD-D8.
- You can still find them for $500 or just a bit under that.
-
- Why not ask this on the DAT-heads mailing list? That's where the net's
- collective DAT experience resides. Are you subscribed? If not...
-
- To subscribe send a one line message with *only* the word SUBSCRIBE in
- the body to:
-
- DAT-heads-request@fedney.near.net
-
- To unsubscribe do the same with the word UNSUBSCRIBE, or UNSUBSCRIBE
- <address>, where <address> is the e-mail address to which your DAT-heads
- mail is sent. If that fails, contact the list owner: liam@near.net and
- wait -- he's busy but eventually he'll unsubscribe you. Please don't
- send unsubscribe requests to the list.
-
- To post:
-
- DAT-heads@fedney.near.net
- or
- DAT-heads@virginia.edu
-
- Ask for their "quality listing," the FAQ, and the microphone FAQ. These
- and the archived DAT-heads digests also available via WWW
- (http://www.atd.ucar.edu/rdp/dat-heads). The faq is available via ftp
- from ftp.atd.ucar.edu:pub/dat-heads and ftp.funet.fi in
- /pub/culture/music/DAT. The microphone faq is available via ftp from:
- www.ultranet.com in /pub/jgm/public_html/mic-faq.txt.

-
- Where excactly is this resistor located? On Midi Adaptor or on GUS
- board?
-

-
- I tried MIDIMON with the midi-input (how does it work with midi
- output?) No problems here. I have been able to locate the problem to midi
- output, not the input: I tried to use GUS' wavetable GM sounds as a
- soundmodule and so without using the Midi Adaptor's output there were
- absolutely no droppings or delays (well, that's some progress, I guess). But
- when I'm trying to get something out from the midi output, there are those
- horrible delays and midi droppings again. It doesn't matter if the midi
- output is coming from a sequencer or playing my master keyboard and using
- midi-thru from my sequencer. Whenever midi is coming out from the computer,
- it's absolutely awful garbage.
-
- >My guess is that your problem lies in the interface hardware.
-
- Me too. But maybe those drivers need some fixing, too.
-
- >I'm not sure how accessible the electronics are, but the next step for me

- >maybe tweak the circuit slightly.
-
- Well, I don't own a logic probe, otherwise that would be quite good
- idea.

-
- Maybe your keyboard is sending uneven velocity values...? Just a
- guess. What sequencer are you using to record/edit your songs?
-
- >Because your problem increased by changing your motherboard, I think you
- >should NOT suspect your MIDI-cable or external stuff in the FIRST place.
-
- I agree.
-
- >Let's try to LOCATE your problem. Take another (= a patchcaching) sequencer

- >your GUS as the soundmodule! Is the problem still there?
-
- No. And when I'm using my external master keyboard to play GUS'
- internal GM sounds, there are absolutely no delays or droppings. So the
- problem is not the midi-input.
-
- >In this case you
- >might have the same sort of problem as I!
-
- Well, I don't have any loud or silent notes (=velocity problems?),
- just those note-on and note-off delays and even completely lost midi messages.
-
- >In this case it must be located between the software and the GUS MIDI-port.
-
- Yes.
-
- >I have in mind the following chain:
- >Sequencer program -> Windows drivers -> (BIOS?) -> ISA BUS -> GUS card ->
- >GUS MIDI Port
-
- That's excactly what I had in mind, too.
-
- >If anyone has corrections or additions to this chain please drop us a line!
-
- Please do so.
-
- >If the problem in your case is located somewhere else, you can of course
- >extend the chain to reflect your external configuration.
-
- Tried already. No change.
-

-
- My old VGA-card was using Local Bus (Avance Logic 2228). I don't
- think the video card causes the problem.
-
- >The last thing i can think of at this time is trying my configuration with

-

-
- I'm afraid he will be facing troubles with that configuration... :-(

-
- Well, this mailing list has certainly been a quiet one for too long :-)
