Thread: Cassette Martenot

    Cassette Martenot

    Hi !

    I have this idea for a long time in mind : create a Martenot like instrument, with one single cassette, and a position sensor like this :

    The idea is to put a single band (going in loops) with the record of a continued note (for exemple an organ, in D1.)

    The position of the finger on the position sensor gives the speed of the rotation of the tape. This way we have a Cassette Martenot.
    I think a teensy could do easily that.

    Do you think it's possible ? Any advice ?

    Thanks !

    Hello
    I know that the simpler way to mimic Ondes "ruban" is use an analog VCO chip
    like SoundSemi ones, but if I well understood you want to make some like a
    Mellotron ?

    PS Francophone ?

    Hi !

    Yes I want it to sound analogic, so I need it to be on a tape..

    Yes, je suis français !

    Chic alors !
    SoundSemi stuff Is fully analogic, of course output is basic waveforms, maybe
    you can use a 4.1 with sampled sounds on SD card and control with a Spectra
    ribbon pot ?

    Hi,
    Analogic, but not a tape right ? Do you have a picture of the device ? Thanks

    Do you want to reproduce Ondes sounds (sine, sawtooth etc.) or Mellotron sampled instrument notes ?

    I want to have a constant note on a tape (for exemple D4) and then play with the speed of the rotation of the band to create different notes. I hope you understand !

    Bien, then a mellotronic instrument, but you want to use necessarily a mechanical tape deck ?

    Hi, yes a mellotronic instrument, but with only one tape, that can be pitched by playing with speed. Yes I want a mechanical tape deck, it's for an art project.

    Now is more clear, well you can use a uC, connect a ribbon pot to ADC and
    control a motor via PWM.
    I guess you can use a Teensy LC for that
