1322.0. "Wanted: MIDI to CV converter" by HUNEY::MACHIN () Wed Apr 20 1988 13:34

    
    I have a moog synth with all the usual ins and outs, and I'd
    like a relatively simple box to do note ons and offs from a midi
    sequencer (a sort of 'note-on' to 'appropriate cv' converter).
    
    Anyone know of such a device?

    I believe Roland makes (or once made) such a device.  Don't know
    the model number.  Will see if I can track it down.  Don't hold
    your breath.

Last I heard, PAIA was designing a kit that does MIDI <==> CV conversion.
Don't know if it is on the market yet, but the price was gonna be in the
below $100 range.

I made a design for one on paper using an 8051 and a 12-bit A/D, but
like most of my other "projects", it never made it into the
implementation stage.

Let me know what you find.  I have an ARP Avatar that I'd love to convert
to MIDI in both directions.  Then I'd have a MIDI guitar controller plus
a fat analog sound source available thru MIDI...

1322.3Roland MPU-101DYO780::SCHAFERWalk between the linesFri Apr 22 1988 16:268
    I think the box you're looking for is a Roland MPU-101. 

    Thought about getting one for my Arps before I sold them.  The box
    cost more than the Arps were worth.

    Good luck.

    I talked to PAIA about 3 monthes ago and they do have CV->midi and
    midi->cv including a mux which will take midi and produce 8 cv's
    (voice allocation) the real kick is that its only 89$ (as i recall)
    call them (I dont have the number, but get it from Oklahoma City
    directory info). They will send you a catalog.
    
    By the way, Anyone out there have a CAT-SRM synth working or not
    working for sale? Mine just died and I want to midi it.!
    
    
1322.5But go ahead and try it if you want...GCLEF::COHENRichard CohenFri Apr 22 1988 18:166
    PAIA stuff usually requires a power supply (hidden cost). Also (from
    experience) their stuff is not generally up to commusic's high
    standards :-)

    Anyone have a recent address for PAIA?  Cheap midi to cv sounds
    interesting. Put that old moog on the net !

1322.7Any practical Advice?NRPUR::DEATONFri Jan 05 1990 12:449
	Having recently obtained a couple of monophonic analog synthesizers with
CV/gate interfaces, I'm interested in either Roland's MPU101 or PAIA's MIDI-CVI
devices.  Has anyone had any experience with either of these?  I have the PAIA
catalog right on my desk and ordering their device is only a phone call away.
They will ship it in kit form or fully assembled/tested.  The difference is only
$20.

    All I can say is thst every PAIA kit I've built in the past, I've
    always managed to screw up something that took a little time to debug.
    For $20, *I'd* buy it assembled.

    Review of PAIA Midi<->CV converter.
    -----------------------------------
    
    	I finally build and hooked up the Paia Midi-CV converter I
    mentioned awhile ago in this conference.
    
    In a nutshell, Im impressed and glad I got it.
    
    It cost $79 as a kit (this price has since gone up to $99)
    The kit consists of a 6x8" circuit board with about 75 parts.
    Sockets are provided for all chips, except the main CPU, which
    is this weird staggerred pin 70 pin deal, which I recommend
    buying and using Molex strips as a socket for.
    
    All you need is an edge connecter, jack for your synths cv and gate
    (my cat srm uses a stereo 1/4"), socket for the wierd chip,
     and a +15/-15 supply. I picked up a nice supply from Micromart 
    mailorder for $12. 
    
    
    I'm a experienced solderer and it took me about 2 hrs to solder
    everything on the board, about 15 minutes to wire up the edge connecter
    to the jacks, and about 1 week to debug the thing.
    
    I powered it up and it didnt work, but PAIA has EXCELLENT support,
    and Scott there was very patient and availbile every time I called.
    Turns out my ground connection to my power supply wasn't good
    and I had a floating ground.
    
    Now it works great. I am able to play tempo 1->500 riffs into the
    thing and my cat follows it faithfully.
    
    The unit also has a simulatious CV->midi, which I have not used.
    Also, it has a DIP switch selectable midi channel for in and out,
    and a RS232 port to talk to its firmware OS. 
    
    It comes with a kit manual, and a developers manual for reprogramming
    it and adding additional features to it.
    Also availble is a 1-64 channel mux that hooks up to it and allows
    midi to 16 assignable CV outputs, including MIDI controlllers to
    CV. Sounds great if you have a patchcord synth.
    
    I would recommend spending the additional $20 for having it build
    for you. Overall, im psyched. My circa 1979 fat analog cat is 
    now on midi channel 16.
    
    any questions let me know.

1322.10DOPEY::DICKENSWhat are you pretending not to know ?Thu Feb 15 1990 15:214
Could you post the current address and phone number for PAIA ?  

How about for Micromart (where you got that cheap power supply !) ?

1322.13Studio Electronics---MIDIed Vintage Analog GearAQUA::ROSTBad imitation of Jerry JemmottThu Apr 26 1990 14:5724
    
    Sounds like this PAIA kit is a good deal.  I saw an article on Studio
    Electonics, the guys who advertise in the back of the music rags for
    their rack-mount MIDIed versions of the MiniMoog.
    
    Their current lineup is the MIDIMoog (the racked Mini), a rack of two
    Oberheim SEM units and a rack of the Roland TR-808.  Coming soon:
    Prophet 5.  
    
    Prices?  Sitting down?  Slightly varying but about $1500 if you supply
    the synth and $2000 if they have to find a used one.
    
    They go in and rehab the unit, add MIDI control well beyond what this
    PAIA thing does....would you believe velocity and CC control of
    parameters on a MiniMoog?  For the Prophet they have obtained the
    source code for the microprocessor and are rewriting it to allow MIDI
    control of almost everything on the machine.
    
    The article also said that the Japanese are now buying up all the old
    analog synths they can find, much as they have sucked up old Les Pauls and
    Strats in recent years.  The first *50* Prophet racks are to be sent to
    a Tokyo music store.  Hmm....

1322.14drooling...DYO780::SCHAFERBrad - boycott hell.Thu Apr 26 1990 15:215
    I wonder if they're considering doing any other P5-era synths? It would
    be great to have an OB-Xa (or OB8, for that matter) than responds to
    CCs, velocity, etc.

    Re: .14
    
    At their prices, you could go buy yourself an Xpander.
    
    It's all based on studio musician demand (thus the TR-808, heard any
    rap records lately?).

1322.16didn't make myself clearDYO780::SCHAFERBrad - boycott hell.Thu Apr 26 1990 15:566
    No, not that (!) - I mean if they can get their hands on the code, and
    blast a few ROMS ... I already have the Xa, and a MIDI kit on it.  I'd
    fork over a few quid to get some opsys mods.  Otherwise, I can twist
    knobs on the fly as well as anyone.

1322.17Looking for CEM chipsHSKAPL::VERGHESEhe ought to see a professionalThu Aug 16 1990 10:2814
    I was wondering, is PAiA still in business? Do they have a
    FAX no.?
    
    I'm looking for a source for CEM synth (VCO) chips. I know Wine
    Country Productions sell them as spares for Prophets, and
    they are priced accordingly - $45 each !!!
    I could use SSM chips, they are still being made (by Precision Monolithics),
    but they have no VCOs.
    
    Didn't PAiA sell CEMs at some time?

1322.18New Midi to CV stuff by PAIAUNXA::LEGAImpeach FlorioTue Sep 18 1990 18:2130
	I have here a brochure for the new PAIA MIDI/control voltage 
	interface and new MUX Expander cards. (comes in kit or built form)
	You can use a system of these things to accomplish

	midi -> cv, cv <- midi

	midi control change -> CV
	ie: pitch, velocity, CC1 (mod wheel), CC3 (chan press), CC4 (foot),
	CC7 (volume)

	Plus various other modes that allow midi to polyphonic CV and/or
	a mix of control voltages.

	The detailed brochure outlines how you can control up to
	64 analog instuments with a system or control lighting 
	with midi.

	I have the basic midi/cv board and can tell you its good.

	Prices for built items are:

	midi to cv	$139	(one midi to one cv)
	MUX master card $ 99	(midi to 8 cvs, many modes)
				(add up to 16 Muxs for more CV out)
	Buss card with
	power supply	$ 39	(backplane for up to 5 cards)

Re .19:

Hey, thanks! I've seen the perennial ad for the PAIA vocoder in EM for what
seems like eons, and often idly wondered if they sold anything else- I'm not
silicon- and solder-literate to the extent that I'd attempt a DIY project of
any significance, but kits I can do!

BTW, FWIW, (love that alphabet soup!) PAIA was connected with the music journal
(can't recall the name) which eventually became EM. The news that PAIA has kits
for all of Craig Anderton's projects (oh so welcome) is somewhat understandable
given the amount of shared history.

Thanks again,
	Bob
