668.0. "QX7 Memory Full, TR707 Sync Err, Spring Reverb for Drums" by DYO780::SCHAFER (ROCK the planet) Tue Jan 20 1987 16:06

    I wasn't sure where to post this, so I'll list it here.  This is
    intended to be a list a miscellaneous nits encounted with various
    equipment.  FYI. 

TR-707, Tape Sync, and MIDI

    If you are using tape sync with/from a 707, make sure you don't have a
    MIDI IN to the 707.  The MIDI clock in will screw up the tape sync and
    cause it to randomly skip pulses.  This drove me crazy yesterday.

QX7 Memory Full

    I don't know about other Yamaha sequencers, but when you *completely*
    fill the memory of a QX7, it becomes brain damaged.  Random things
    happen to the recording track (1), the most common of which causes the
    display (and track 1) to stop at a random measure.  (Track 2 plays
    happily along with no indication of where it might be.  The only way to
    get track 1 back is to re-record it.

    You know you're getting near the edge when the display starts flashing
    "nF".  You have roughly 48 - 64 notes left to stop before it performs a
    self lobotomy.

668.1No!! I won't enter a title! You can't make me!!JAWS::COTELet's change the rules and giggle!!!Tue Jan 20 1987 16:1813
    Since the QX7 has only a 2 character display they had to compromise
    on some of the abbreviations. "nF" is a condensed version.
    
    Hint - Score big gobs of memory on your QX7 by deleting the contents
    of the temporary buffer. This buffer holds the unquantized rev of
    your last hatchet job ("Why play tight? I can quantize!!").
    
    D2-B4(1)-D2 will get you acres of luscious green bits in which to
    sow your musical wheat.

Re: .1

    Thanks for the hint, giggles.  I thought that the quantize function had
    its own buffer which was seperate from main memory. 

    Another unrelated gripe - I've been using a spring reverb (built in w/
    mixer board) to get some ambience in my recordings.  I've been having a
    heck of a time trying to get boing out of percussive patches. (I've
    almost given up on reverb for the 707.)  What do I do?  Do digital
    units have this problem, or is this peculiar to spring reverbs?

    Maybe a little more volume ...?  Nahhh.  Help!

668.3They're Great. Don't Buy OneDRUMS::FEHSKENSWed Jan 21 1987 14:3510
    Spring reverbs do not mix well with percussive sounds.  I know of
    no way to get rid of the "boing".  Digital reverbs don't go "boing"
    on percussive sounds, but they can produce a "hissy" kind of tail
    on a percussive sound.  Sharp percussive sounds are one of the real
    tests of a quality reverb.  One of the reasons that I like the Roland
    SRV-2000 so much is that it works *very* nicely on percussive sounds.
    (Not to be construed as a sales pitch.).

668.4Boingie, Boingie, Boingie...JAWS::COTEIn Search of Excellence. Seen any?Wed Jan 21 1987 14:4112
    Different springs have different amounts of ping....
    
    The spring in my mixer is all but useless for percussion, but I
    have a fairly high-end (is that an oxymoron when discussing springs?)
    Fostex unit that is considerably more usable.
    
    I've heard that springs of different lengths in the unit will cut
    down on the boingies.
    
    Mix-master Dreher also tells me they can be eq'd into submission.

    Jam Master 'D' here.
    
    I've had success with spring reverbs by EQ-ing the high end off
    the reverb return.  Start high and work your way down in frequencies
    until it disappears to an acceptable level.  I used a spring reverb
    on the Linndrum snare and congas on Acapulco, which is on COMMUSIC I.

668.6length. JON::ROSSdont shoot the MKS20 player!Wed Jan 21 1987 16:3519
    
    Must say that the shorter the springs, the :
    
    	1. Boingier they are (cant eq out. makes a 'noise')
    
    	2. They have a resonant peak mid to low freqs somewhere.
    		(Might eq out)
    
    High end hiss from mega-amping the teensy signals out of these
    critters is of course eq'able. The 16inch or so spring in my
    2600 is very good. The 6 to 8inch springs Ive experimented with
    are downright poor.

668.7Thanks & undocumented feature of SRVDYO780::SCHAFERROCK the planetWed Jan 21 1987 17:259
    Thanks.  I tried eq'ing the snare, but I lost tone altogether. Did NOT
    try eqing verb return.  Will screw with that this evening. 

    BTW, Len - did you read the reader comment in Keyboard (Feb 87) that
    you can get digital delay out of your SRVs?  Seems that you can press
    three selectors (?), power up, and voila! the display comes up with
    "DELAY".  I'd be interested to know what the deal is.

    Thanks, Brad, but see my review of the SRV where this "feature"
    is described in full detail (including how all the parameters work).

    Brain damage.  Now I remember.  I should have known that no feature
    can escape the grasp of the mighty len.  ;-}  Egad, I must be tired.

668.10QX5 nit fix, if you've got the gutsECADSR::SHERMANThings get curioser and curioser...Tue Jun 02 1987 20:4719
One of the nits I have with the QX5 is that it has only one MIDIout.  It has
a MIDIthru, but I have no use for it.  I found I needed one more output, and 
I didn't want to buy/build a thru-box.  So, I found that a simple jumper fix
in the QX5 was sufficient.  This probably voids the warranty (so sue me!), but 
it works well and satisfies the MIDI specs.  If you open the box up and get to
the board that has the MIDI sockets on it, you'll see three jumpers labelled
J20.  Cut the middle jumper and solder the end closest to the sockets to the
jumper on the right.  This will make the MIDIthru socket circuitry drive by 
the same driver that drives the MIDIout socket circuitry.  Yamaha pretty much 
follows the MIDI spec for the circuit except that they add what looks like some
kind of resistor/fuse/filter pack in line with the sockets.  If you do decide
to do the fix, be sure you know what you're doing i.e.; be especially careful
with the ribbon cables and connectors and with the display board which has some
hairy surface-mount stuff on it.  I was tempted to mount a switch so that the
MIDIthru would be programmable, but I'm too lazy and cheap.
