If anyone wants a challenge.... IMHO the holy grail mod for CZ-101 (and presumably the other CZ synths) is a data wheel or knob. Unlike a lot of 80s digital synths, programming a CZ is actually really easy and straightforward.....but it’s still a PITA because everything relies on the two up/down bu...

Yeah mine is up and running

I have been working on a solution for the unobtanium scale switches for this project and I finally have something to show. Figured I would post here to maybe catch anyone who has worked on this project but doesn’t frequent the RE-303 forums or Facebook group. 63261B15-3C03-44D8-94C9-104B23FB11AF.jpe...

This was probably an ill-conceived thread to start when I have DIY modules for sale in BST, but I thought there should be a thread for us to come and say bad words when we are done thinking and troubleshooting, and just want to vent. I can’t speak for anyone else but me, but personally I’d rather b...

I might lean toward option 2. The kick on the 110 is probably the least interesting sound it has. Also, not having heard what the pitch/decay mod in this currently sounds like, I associate these type of analog drum mods (tried similar stuff with a DR-55) with a really small sweet spot of actual usab...

I was wrong!

Wow, that’s amazing.

Apologies. No insult was intended. If the only thing that will do is a 16n full kit, I am not aware of anywhere you can get one cheaper than what you’ve found.

Slow down a bit. Realize that you’re asking for things that are somewhat opposed to one another—you’re asking for as much of the work as possible to be done for you, but also that you not pay for all of that extra work. If cost is your main concern, you should teach yourself some critical DIY skills...

Replace with a shorter electrolytic

(This is 85% a joke, but also thought it should be mentioned just in case it hadn’t occurred to you.)

Glad you got it sorted! I’m about to work on a similar issue on a 202.

Do some diagnostics before just replacing everything. There is a lot you can check before even turning on your soldering iron. Every time you heat a PCB, you reduce it’s expected lifespan, so especially with highly valuable and collectible instruments, it’s worth the effort. Do you get a clock signa...

Just ordered a blue pill to give this a shot. Thanks!

It’s true that there’s not much more than resistors in the schematic, but there are two issues with proceeding based on this assumption. One, it’s quite rare for resistors to just...die. Two, there’s more to a synth than its schematic—if you open it up and look at this section, there’s a switch that...

And a few of the items I've noticed people say isn't very good from them is crap from all suppliers, so it's more the manufacturing quality, not the supplier's fault. It wasn’t always like this, as the OP implied. Just a few years ago they had a much wider selection of crap components. Lots of fake...

Somewhere I have an OPL3 chip set that’s been waiting for a project like this...

The film caps I've had from there are fantastic, every bit as good as the $$$ ones I have used in the past.

Do you use the little box caps or the greenies?

I have avoided buying 1900h knob clones there, as I’ve been advised they lack the internal copper collar (ie, set screw is threaded only into plastic). I like to get my set screws real tight, so I went with some cheap AliExpress clones that include the copper collar instead. I have bought other knob...

I use my TTSH as an output module

Got some cool audio chips to play with and just spent an hour wondering wondering why my shit wasn't working...the pinout on the first page diagram on the coolaudio datasheet is wrong!! The Vc4 pin is swizzled. I was wondering why the thing wouldn't just be nice and symmetric so I opened the SSI216...

I ordered some of these by mistake (wanted 1.3"): 128x64 OLED Module SPI 0.96"Graphic Displays,White on Black Free to good home! I have 5 to go Just realized I have a couple of them too. Any ideas where they could be used? If you have any old synths/computers that still use a floppy drive, you can ...

Had lots of success with PM Foundations so far. I've messaged the owner a few times and he's always been very helpful. What do you think of the quality of the front panels? I've never used the pcb material for front panels yet and am curious if they feel as sturdy as metal ones. Honestly don’t noti...

My main “trick” for stripboard: learn KiCAD ASAP because stripboard is super annoying!

There’s one resistor change to make when using the Alfa clone but otherwise they’re pin compatible.
