Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Casio Casiotone MT-40.

Setup and maintenance

  • A common issue is interference leaking into the noise generator transistor, possibly due to a failed capacitor or ground path issues.

    Source
  • The rhythm section's ringing noise can be linked to a malfunctioning D325 transistor, which connects via three wires on the board's bottom.

    Source
  • After an IPA bath, ensuring complete dryness, especially for contacts and switches, is critical to avoid malfunction.

    Source
  • Most multimeters cannot check capacitance in-circuit effectively; specialized tools or removing components may be necessary for accurate diagnosis.

    Source
  • To avoid static damage when modifying, use an anti-static wrist strap or touch an earthed metal object, and avoid soldering while plugged in.

    Source
  • Consider using a resistor or small capacitor on outputs to buffer against capacitive coupling when modifying for separate outputs.

    Source
  • It's crucial to use a 9V power supply with correct voltage to avoid damaging internal components, even if the amperage matches.

    Source

Mods and upgrades

  • Adding separate output jacks for bass and drums involves intercepting at test point 7 after an 820K resistor and potentially cutting a trace or lifting a resistor.

    Source
  • Original volume pots for bass/drum mix and overall volume are 10k linear; bypassing may require recalibration to prevent impedance mismatches.

    Source

Features and functionality

  • The Casiotone MT-40 uses three 4558DD op amps; one serves as a mixer, and the bass and drum signals share a trace to the mixer.

    Source
  • The MT-40 requires a center-negative power supply, similar to some retro gaming consoles like the Sega Genesis.

    Source

Use cases and applications

  • Modifying for separate outputs can enhance live dub performances, inspired by channels like Manudigital's UK sessions.

    Source

User experience

  • Owners advise against using a power supply with higher voltage than specified to prevent potential damage to the MT-40's internals.

Great design, great bass and amazing presets, lacking drums.

I've owned two of these (they tend to degrade over time so I've never had one that was perfectly functional) and the instruments are great. I just love the unique sounds that keyboards that do synthesis as opposed to PCM/sampling have. The iconic bass holds up just fine to this day, and I still use it in some of my tracks. The drums are honestly the biggest drawback for this keyboard, the snare is terribly dull and the drum patterns are so simple. Even Sleng Teng has a clap overlaid on the snare in the riddim, if you can't take my word for it. Not to mention that both MT-40's I've had have a terrible ringing noise in the drums from some sort of open connection, which makes using them pointless anyway.

Great drums massive bass

Search youtube for MANUDIGITAL, he has plenty of songs with Reggae artists and this machine only. Battery operated (the chunky ones) , simple machine. Basic fills on the (analog) drums, a simple 4th and 8th notes with the kick and snare, but can make your beats interesting. The bass keys are on the left, very good bass tone which can not be altered. A one man band can not get any simpler than this. There is also a dark version of this -> MT-41.
