2502.0. "Roland CP40 - Pitch to midi converter" by MLNCSC::M_FRANZONI (Blue like a Blues) Tue Nov 27 1990 14:41

Does anyone have any information about Roland MP40 - I'm uncertaing about
the model name, anyway is a pitch to MIDI converter that, according the ad
I saw on a magazine, is able to convert any analog signal (generated by
mic, or electric guitar or so ...) to MIDI.

I'm interested in functionality and price (in us and/or uk)

Also, I would be interested in any cheap pulse-to-MIDI converter (and what else
is required) to connect an acoustic (and/or practice) drum/set to an Amiga with
MIDI interface, running sequencing software.

Thanks for any info,
Cheers, Mauro.

2502.1It's about DM 550IBEEAM::GENIUSI'm *not* this mouse!Wed Nov 28 1990 10:1310
Roland's Pitch-to-Midi converter is exactly what you said. It supports either 
voice input via microphone or guitar pickup. If you can accept some tracking
especially on low frequencies it is a very useful tool for converting
your humming into Midi signals.

By the way: I am selling mine for DM 420,--.

I could be interested, where are you located ?
Anyway I'd like to try one before (looking for a dealer here), so don't refuse
other offer.

BTW, CP40 it is introduced (by the ad I saw) as the latest Roland product ...
are we (in Italy) so late as usual, or is it actually a brend new product ?

... and again, any info about pulse-to-MIDI converters ?

Thanks, Mauro.
2502.3Acoustic piano -> MIDI ?CLADA::ODEAJohn O'Dea GAO DTN 822-2983Thu Nov 29 1990 10:254
    I wonder could you hook this to a grand piano and drive a midi synth
    with it ?

    re: .1:
    
    why are you selling yours?  strapped for cash, or doesn't it do
    what you wanted it to?
    
    are these available in the uk?  (italy isn't the only country where
    products arrive a couple months after release in the states!).
    
    if it's mono only, that just means you have to play each piece 10
    times, doesn't it? :-)

I asked a dealer about it, it's mono voice ... he couldn't answer about chords
(e.g. guitar) handling because he just tried it with microphone (vocal) ...
he'll do it as soon as he'll receive the new delivery (he sold all the units he
had).
My guess (my hope) is that it can recognize the chord note but not its
components (so you'll need a little editing on the part, after the sequencing)
I just wonder how well it does it...
BTW, I phoned to Roland Italy as well, but they seemed to be less informed than
the dealer.

Good question.

Here products usually arrive a couple of months after all the other european
countries received it a couple of months after the release in the states...

Cheers, Mauro.

    re a pitch to MIDI converter - a friend of mine has one, and we tried
    to get it to emit MIDI by playing guitar chords... it will NOT do it.
    in fact, it's VERY sensitive and has a hard time with pitch-wavering 
    vocals or too quiet signals.
    
    best of luck, but I don't think it'll work for you.  karl
2502.8is that the Roland?MINNIE::DOUGWhen half-gods go\The gods arriveMon Dec 03 1990 20:114
    re: .-1  are you talking about the Roland one?  or another one? there
    was another one released about a year ago, which did exactly as you
    describe.  i was hoping that roland (being a kind of "big" company)
    could sort out these kinds of problems. 
2502.9KEYS::MOELLERForgot 2 pay my gravity bill againMon Dec 03 1990 21:455
    .. I think it was called the Pitchrider.  Been about a year.
    sorry for the ambiguiuty, but my impression that all pitch to MIDI
    converters have a definite mono in requirement.

    Pitch to MIDI is going to be an essentially mono thing until someone
    is willing to throw hardware at it.   Poly output is possible, but it
    takes a much more involved analysis, with FFTs.  Mono output can be
    done by filtering and counting zero-crossings.  To do the FFTs fast
    enough will require DSP chips and very fast processors.
    
    This is if you want to do it in real time, of course.  If you are
    willing to do it slower than that, you can do it in software on a PC.

    How well does it handle doing one note at a time on the guitar?
