@JonathanChunPrevenge Yes, the same mods will work on the HT 3000 as the HT 3000 uses the same sound engine as the HT 700. About the only difference between the two is that the HT 3000 has full size keys and has a mod wheel.
Lots of 80's synths had knobs...polysix, prophet 5, memorymoog, and lots of others..like the oberheim ob series.
Knobs are crucial if you want to make your own sounds. You need either knobs or sliders in order to have quick hands on editing and tweaking...otherwise you may as well use a piece of shit dx7 which nobody bothered to program because it was so convoluted and unfriendly.
(most DX7 sounds you've heard on records were presets for this reason)
@SPAZZOID100 The were these couple guys who programmed all the DX7 presets in four days, because they had deadline to meet. These four days contributed to years of DX7 supremacy. These guys simply knew what they were doing. Knobs are for lazy dudes, who can't focus their attention to learn something.
@SPAZZOID100 Life is short indeed, but I enjoy reading keyboard manuals and twiddle with Parameters. My favorite synths are the D-50, DX7, Casio CZ-1, VZ1, etc. My Minimoog Voyager OS has been sitting in the closet for last year or so.
@SPAZZOID100 Agree with that. Although having a keyboard with velocity and aftertouch, and mod and pitch bend wheels is enough of a real time control for a musician. Look at Chick Corea's playing, he masterfully uses all these controls on Yamaha KX5, which my favorite remote keyboard. If you can't do with these controls well, then the knobs won't help you.
@SPAZZOID100 I payed $250 for mine couple years ago at Manny's Music. Even though the oscillators are distorting a bit, the cosmetic condition is quite good. Then I paid $350 I think, for a DX7IIFD at Rogue Music. That one is super clean, and so is my D-50 for $450, also from Rogue. For the HT-700 I paid $100 in a brand new condition with original box and all. I would never do such a damage to it like the guy in the video. I don't have the kind of money to go for a Jupiter 8.
@SPAZZOID100 Back in the late '80s, I had the HT-6000. It was my first serious keyboard after a Bontempi toy electronic organ. Then I sold the HT-6000 when I got the VZ-1. Then I sold the VZ-1 when I got the D-70. All I can say now after all these years is that the HT-6000 was a very serious synthesizer. I didn't realize this in the old days, but I realize it now. Oh well, sometimes we learn the hard way. The HT-700 is a simplified version.
@butheadVSbevus Try the Casiochord function on the Casio CT-410V/ MT 400 and run it through the factory standard onboard analogue filter - it takes on a whole new dimension and sounds very cool ;-)
I saw your page on modifying the MT-600 filters, is it generally the same with the HT-700? I found one today in town dirt cheap - the power input was damaged but I replaced that with ease - I bought the keyboard for circuit bending but it looks like it may be more worthwhile to turn it into a decent synthesizer... p.s the casio funk vid rocks :P
congrats on the ht700 find! the filter is the exact same IC as on the MT-600; main difference is the ht is a programmable paraphonic hybrid analog synthesizer, kinda like the Poly-800.
If it were me, I'd mod rather than bend the HT because it is programmable. I prefer one-knob-per-function controls, though and that's why I did these mods.
one note to be aware of: the HT has no VCA at the end of the sound chain, just an analog switch. so you have to take care with the filter resonating...
Thanks for posting this! I was just about to sell my HT-3000, but this made me think otherwise! Awesome mods. I'd love to get the info on how to do these mods!
I used to have a HT 3000 back in the 80's and I'd love to know how you did this. How did you add the cut-off and resonance pots? Did you need to use any ICs or just solder pots to the right place?
two people in a row asking how to program the loop!
I can't really detail it here, but it is in the Owner's Manual, which you can get on the web. I think Casio New Zealand has posted a copy.
maybe I'll post another video that shows how to program the loop (but not too soon - I'm swamped with work). besides, I still have to get the schematics of the mods together!
My documentation of this is a mess right now, and I have one or two more mods to go, but after I get them cleaned up, I definitely will post them sometime soon!
I like your circuit bent! I've got the same model, but i'm newbie in synths so I ask: how did you programmed the loop (the thing you play with using effects)?
I'm just wondering if you managed to "clean up" the documentation for the mods (though I could probably use even a "dirty" one :P )
Great job there.
Personally I wasn't so smart to figure out all this, just accidentaly stumbled upon a partial control for one of the filters cutoff. I would realy-realy appreciate some hints about this :)
Would this work for a Casio HT-3000?

I'd never do this to an instrument. The knobs on 80's keyboard are totally out of place. They destroyy the sleek style of the instrument. Sorry.

The dx7 was good for 4 sounds, let's face it.
Knobs for lazy dudes? NO dude, life is too short to be fussing around with parameters which are buried in sub menus of menus, don't you think?
Look, you have the right to your own opinion, as backwards and warped as it is.

Interesting assessment.
As far as i'm concerned, the minimoog voyager has 100 times more grit and personality/warmth than all those synths you mentioned (put together)
SPAZZOID100 1 year ago
@SPAZZOID100 Nah... The Voyager is cleaner than the Model-D. Not much grit, really.

I payed $60 for my DX7...i'm very happy that I didn't pay more for it.
Jupiter 8's go for $5,000 now...nobody would ever pay that for a dx7
