Gearfacts: Definitely appeared as if you were having fun with it. 😁

I've been reverse engineering the synth chip they used in this and a few other keyboards, I had heard some glitches like this while deliberately messing with it but had no idea they were so easily accessible from the front panel! It makes sense that most of the glitches are related to pitch envelopes and detune (9:40, 10:08), as the internal pitch table is pretty small and it's easy to run off the end of it into other data. The volume envelope glitches (5:24) sound as crunchy as they do because the internal timing for that is pretty loose/uneven. I have a MT-750 I've been repairing (one of the worst battery leaks I've ever seen) and that uses the same chip with I think higher quality samples, will love to play around with the tone editor once I get it to a usable state.

Este teclado/sintetizador de Casio de los 90 fue una joya para la época, sin mucho esfuerzo podría atreverme en mi humilde opinión decir qué podría haber competido con el Yamaha DX7 , salvando las diferencias por supuesto, un sistema de banco de sonidos bastante completos, con efectos que podrían competir con cualquier sintetizador de alta gama. Esto es una demostración que Casio cuando quería sacar teclados buenos no hacía solo juguetes. Saludos desde La Rioja, Argentina.

I got this keyboard in the 5th grade as a birthday present, 1 yr after I began piano. It was great, had a blast on it. Just a few yrs later, my older brother borrowed it to college and lost the power supply, bc he always did that shit to me. I never used the keyboard again. Even though it just needed a PS, i didnt bother bc i honestly thought it was like a "nice toy" keyboard. I was young and dumb and didnt know anything about digital music. Still, barely do. I played classical piano through college and have used my talents off and on over the years. But, since i love the instrument, i never threw away my first keyboard. 32 years after my 11th bday, it looks to be in amazing shape! So, I just now stumbled on this video on Google trying to figure out what type of power supply (are all 9v power supplies the same?) my damn brother lost so I can lend this keyboard to my first ever student. But yeah, I love random youtube docs and I am so excited to learn about my old "toy." I have a feeling I'm not going to want to lend it. Edit* great vid!

Which would you pick, the Yamaha PSR-36 or the Casio CT-670? You made a video of each. I see a CT-670 on sale for $40 near me and a PSR-36 on sale for $60. I don't really care about the price difference, I just want the better / higher-end product but I have no idea which is better. Thanks!

I cant seem to get it to move with a pair of plyers? Thanks. Dan

I was surprised by the lack of zipper noise when using the 'Tone Editor'. I have the Yamaha PRS16 with a similar editor on it yet that just has 5 steps (I think) per parameter which makes it more limited. Guess I will just have to try and find one of these!

@@gearfacts Zipper noise is that horrible sound you get when actively changing a value with a digital pot and you can hear the discrete values being stepped through rapidly. It is a problem with early digital and/or budget gear, where the resolution of the steps is very low. Think of a detailed picture shown on a screen with very low bit resolution. In audio terms I believe it also adds a lot of enharmonic tones as it is in effect applying a square wave onto the audio, on top of the clunky steps themselves. I hope that makes sense. :)
