  • This is my full review about the Casiotone MT-70, a keyboard from 1982. It is one of 6 Casio keyboards that uses sine waves instead of multipulse square waves. It has a memory system with barcode reader pen, 20 Instruments and 10 Rhythms.

    My grandfather has a MT-70, I remember playing with it when I visited them during the holidays. If I recall correctly, this was the second keyboard I put my hands on, the first being a Casio SA-38 PCM-based keyboard. I rembember thinking it sounded kinda weird, as I had never heard anything like it before. Never really touched the memory stuff as I kept myself sufficiently entertained playing with the chords. Never knew about the barcode reader!

    My mom bought me one of these recently from an old lady who passed away and I've been having so much fun with it. Unfortunately it didn't have the power supply, so I'm running it on batteries, but it's been lasting quite long on them so I can't complain too much..

    • @riley1636
      @riley1636 2 місяці тому +1

      If you haven't already, you can buy a power supply, just make sure its the right DC voltage (they make universal with changeable voltage) and make sure the tip size is correct (the universals also have changeable tips). I believe in the video he showed it needed 7.5 V. If your supply doesn't have that exact value, try the lowest which is closest and then the next one up if that doesn't work. Typically batteries are 1.5V each so you can use this for reference for the # of batteries you use. If you have any questions feel free to reply.

    Hi! I just discovered this channel and it was an insta-suscription. But, most important, I'm here looking for help.
    I happend to have this keyboard. It was cheap in facebook's marketplase near me and I wanted to practice keyboard for a long time, so it was a win-win situation.
    The thin is that it doesnt wark quite well. You see, when I put the Casiochord switch to fingered or On, the first octave and a half doesn't work. But, when it's Off, It kinda works. I press a note repetly, but it just a few times. But, this error happens in all the keys. When, with the switch on or fingered, they work correctly.
    Also, the speaker its a bit noisy. I don't know if it's dirty or it's just interfirence.
    Thanks to anyone that can help and, again, amazing channel!
